2011-11-01T02:05:44 < zhanx_laptop> having issues making the demo's on ubuntu anyone got ideas?
2011-11-01T02:06:04 < zhanx_laptop> make says there is nothing to do
2011-11-01T02:06:31 < karlp> which demos?
2011-11-01T02:06:44 < zhanx_laptop> the stm32f4 discovery ones
2011-11-01T02:07:12 < karlp> what compiler are you using?
2011-11-01T02:07:15 < zhanx_laptop> i got board commo etc but they are not compiling with my generic makefile
2011-11-01T02:07:33 < karlp> board commo?
2011-11-01T02:07:38 < karlp> your own makefile?
2011-11-01T02:07:47 < karlp> that doesn't sound like the demos, that sounds like your code :)
2011-11-01T02:07:49 < zhanx_laptop>  summon-arm-toolchain with gcc
2011-11-01T02:08:39 < zhanx_laptop> gcc CONFIG_STM32F4_DISCOVERY=1 main.c fails
2011-11-01T02:08:58 < zhanx_laptop> think i need to update my paths first
2011-11-01T02:09:07 < karlp> which demos are these?
2011-11-01T02:09:14 < zhanx_laptop> the st ones
2011-11-01T02:09:24 < zhanx_laptop> let me update my path and try again
2011-11-01T02:09:35 < BrainDamage> gcc by default calls the native x86 compiler
2011-11-01T02:09:47 < BrainDamage> you might want something like arm-none-eabi-gcc
2011-11-01T02:10:39 < zhanx_laptop> k
2011-11-01T02:10:51 < zhanx_laptop> arm-none-eabi-gcc i will try
2011-11-01T02:11:13 < BrainDamage> also, that env var, sounds like something you'd pass to a makefile, not gcc
2011-11-01T02:11:30 < zhanx_laptop> k
2011-11-01T02:11:35 < zhanx_laptop> fails also
2011-11-01T02:11:38 < karlp> what is the link to these demo's, and this makefile you're using?
2011-11-01T02:12:00 < zhanx_laptop> i skipped the makefile on the last command
2011-11-01T02:12:17 < zhanx_laptop> arm-none-eabi-gcc
2011-11-01T02:12:19 < zhanx_laptop> err
2011-11-01T02:12:23 < zhanx_laptop> arm-none-eabi-gcc main.c
2011-11-01T02:12:33 < zhanx_laptop> will paste bin the error message
2011-11-01T02:12:42 < karlp> where did you get this makefile from?
2011-11-01T02:12:57 < zhanx_laptop> i made it
2011-11-01T02:13:04 < zhanx_laptop> very very basic
2011-11-01T02:13:22 < karlp> perhaps too basic? ;)
2011-11-01T02:13:36 < zhanx_laptop> http://pastebin.com/EB3jBNRx , thinking i need to add a few more lines to my path
2011-11-01T02:13:46 < zhanx_laptop> as it finds one file now
2011-11-01T02:14:29 < karlp> you probably need a few -I parameters
2011-11-01T02:14:56 < karlp> also, some of the stm32 download examples won't compile unedited with gcc, they have attributes and pragmas for other compilers
2011-11-01T02:15:38 < zhanx_laptop> k
2011-11-01T02:19:49 < zhanx_laptop> this is the last thing i need to get going in order to compile my code and upload etc
2011-11-01T02:23:54 < zhanx_laptop> searching for thw lib that contains RCC_AHB1Periph_GPIOD and i should be good
2011-11-01T02:29:29 < zhanx_laptop> hmm i cant get an empty file to compile either
2011-11-01T02:30:23 < karlp> can you build the examples in https://github.com/texane/stlink ?
2011-11-01T02:30:31 < karlp> that has blink examples for f4, with makefiles
2011-11-01T02:30:44 < zhanx_laptop> will try
2011-11-01T02:31:46 < zhanx_laptop> main.c:86:2: error: #error "Architecture must be defined!"
2011-11-01T02:32:15 < karlp> make CONFIG_STM32F4_DISCOVERY=1 ....
2011-11-01T02:32:36 < zhanx_laptop> k
2011-11-01T02:32:57 < zhanx_laptop> yep i can make tht

2011-11-01T16:44:38 < Laurenceb> https://github.com/willdonnelly/pirate-swd
2011-11-01T16:57:02 < karlp> heh, more duplicated effort :)
2011-11-01T16:57:30 < karlp> there's a guy who wrote the scsi pass through that the VL board needs, but he did it for an STM8,
2011-11-01T16:57:42 < karlp> almost identical, but no-one talked to each other, as usual :)
2011-11-01T16:59:07 < karlp> he even apparently developed this to program it from linux, which was already supported back in march from stlink.
2011-11-01T17:00:35 < karlp> looks like some useful stuff though.
2011-11-01T17:03:27 < karlp> oh no, my bad, he did this in 2010, not 2011

2011-11-01T19:07:38 <@jpa-> karlp: well, doing swd using bus pirate is useful if you don't own a stlink board :)
2011-11-01T19:08:19 <@jpa-> (though they are so cheap that not exactly worth the effort)
2011-11-01T19:58:16 < karlp> true, the swd work is useful,
2011-11-01T19:58:27 < karlp> it should get slurped into openocd,
2011-11-01T19:58:37 < karlp> so it can be used with a buspirate, or anythign else though,
2011-11-01T19:58:43 < karlp> openocd has a buspirate backend iirc
2011-11-01T20:08:22 < BrainDamage> can't openocd get a stlink driver now that there's some code available around?
2011-11-01T20:08:30 < karlp> sure,
2011-11-01T20:08:51 < karlp> but I haven't gotten far enough in my own development to start submitting patches yet :)
2011-11-01T20:09:03 < karlp> I wasn't using openocd before, so it's not number one on my list of things to do :)
2011-11-01T20:09:28 < BrainDamage> understandable
2011-11-01T20:09:29 < karlp> but the girlfriend  just left town with work for a week, so there should be a few hacking nights this week :)

2011-11-01T21:17:31 < karlp> man, I can not work out a quirks mode to get this VL board to attach peacefully.
2011-11-01T21:18:45 <@jpa-> they never do :)
2011-11-01T21:19:04 < karlp> well, I was hoping that there would be acombination of quirks that would work :)
2011-11-01T21:19:13 < karlp> was trying them out over dinner :)
2011-11-01T21:19:19 <@jpa-> mine spams dmesg for the first 30 seconds after attaching, giving 100% cpu usage :)
2011-11-01T21:19:25 < karlp> only 30sec?
2011-11-01T21:19:28 < karlp> hah, lucky you
2011-11-01T21:20:05 < karlp> I get no cpu, but it's more like 3-5 minutes

2011-11-01T21:33:03 < karlp> hang on, which problem?
2011-11-01T21:33:17 <+Steffanx> That great stm32vl discovery + linux
2011-11-01T21:33:19 <+Steffanx> + os x won't boot with the stm32vl discovery
2011-11-01T21:33:24 <+Steffanx> connected
2011-11-01T21:33:28 < karlp> oh yeah, my linux doesn't boot with the vl connected
2011-11-01T21:33:43 <+Steffanx> Here the bootloader doesn't like it i think
2011-11-01T21:33:44 < karlp> it normally eventually settles down, but it's a DOG compared to the 32L
2011-11-01T21:34:02 < karlp> and presumably the F4 too, I believe it has the same stlinkv2 as the 32L
2011-11-01T21:34:02 <+Steffanx> I think the bootloader tries to do something with the fake mass storage device
2011-11-01T21:34:19 < karlp> yeah, it robably tries to work out whethe rit's a bootable driver
2011-11-01T21:34:22 <+Steffanx> Both st-link/v2 not?
2011-11-01T21:34:31 < karlp> 32L and F4, yeah, I believe so
2011-11-01T21:34:49 <+Steffanx> We need a fw update for the stm32vl
2011-11-01T21:34:56 < karlp> hah
2011-11-01T21:35:18 < karlp> would be nice, I'm sure the stlink can be put in dfu mode...
2011-11-01T21:35:36 <+Steffanx> Yeah, you have to use windows though
2011-11-01T21:35:55 <+Steffanx> The st-link utility has the tool for it
2011-11-01T21:36:13 < karlp> I'd be ok with that,
2011-11-01T21:36:23 < karlp> finding a windows machine long enough to do a fw upgrade is one thing,
2011-11-01T21:36:30 < karlp> having to use windows to use it at all is a different matter
2011-11-01T21:36:56 <+Steffanx> I have a vm for things like that

2011-11-01T21:44:03 < BrainDamage> I've seen some people that actually put the versaloon firmware on the vl
2011-11-01T21:44:30 < BrainDamage> which makes it openocd compatible too
2011-11-01T21:44:38 < Laurenceb_> does stm32 have a lockbit?
2011-11-01T21:44:54 < Laurenceb_> im wondering it its possible to grab the firmware off stm32discovery
2011-11-01T21:44:56 < karlp> on which, the stm32 that is the stlink, or on the "demo" part itself?
2011-11-01T21:45:02 < Laurenceb_> to get st-link v2 firmware
2011-11-01T21:45:18 < BrainDamage> the stlink part
2011-11-01T21:45:20 < Laurenceb_> has anyone tried?
2011-11-01T21:45:22 < Laurenceb_> yes
2011-11-01T21:45:49 < karlp> how were they doing that?
2011-11-01T21:45:49 < BrainDamage> there was the thread http://www.versaloon.com/bbs/viewtopic.php?f=2&t=17&sid=6910fa04143bf8349a8fd15d6937ccbc
2011-11-01T21:45:57 < karlp> takk
2011-11-01T21:46:18 < BrainDamage> see also http://takenapart.com/?p=82
2011-11-01T21:46:24 < BrainDamage> which is much more clear
2011-11-01T21:46:57 < karlp> ahh, yeah, heðs using a working stlink to program via leads on the donor's swd pins
2011-11-01T21:47:19 < BrainDamage> yuppers
2011-11-01T21:47:20 < Laurenceb_> how come there are only two jumpers?
2011-11-01T21:47:27 < Laurenceb_> what happens to the reset wire?
2011-11-01T21:47:33 < karlp> swd doesn't need the reset
2011-11-01T21:47:37 < Laurenceb_> oh
2011-11-01T21:47:54 < Laurenceb_> cool
2011-11-01T21:48:20 < Laurenceb_> my stm32F4 discovery should arrive tomorrow
2011-11-01T21:48:27 < karlp> the "SWD" header on the stlinkv2 boards has 6 pins, and includes a reset and a reserved, but I've programmed a VL board via SWD from a 32L board with just three wires, (SWD, SWCK and ground) plus power
2011-11-01T21:48:27 < BrainDamage> I've got a standalone stlink here before I could grab my hands on a discovery vl
2011-11-01T21:48:31 < BrainDamage> now I wish I didn't :/
2011-11-01T21:48:43 < Laurenceb_> RS have them in the UK
2011-11-01T21:48:48 < Laurenceb_>  £12
2011-11-01T21:48:59 < Laurenceb_> +vat and postage and everything :(
2011-11-01T21:49:00 < BrainDamage> does it have sane shipping costs? I'm in italy
2011-11-01T21:49:16 < Laurenceb_> dont know.. they do international shipping
2011-11-01T21:49:45 < BrainDamage> every US-based store charges me with courier -> 20$+ shipping :/
2011-11-01T21:49:59 < karlp> I only order them if work has an order going out
2011-11-01T21:50:11 < karlp> mosuer/farnell/rs/digikey all have silly shipping
2011-11-01T21:50:24 < BrainDamage> I'm a poor student
2011-11-01T21:50:35 < BrainDamage> no workplace I can piggyback with
2011-11-01T21:51:08 < karlp> local hackerspaces sometimes do group orders?
2011-11-01T21:51:36 < BrainDamage> what hackerspace?
2011-11-01T21:51:40 < karlp> hehe
2011-11-01T21:52:01 < BrainDamage> the only hackerspaces here are interested with software
2011-11-01T21:52:15 < BrainDamage> at least, all the hackerspaces I could find on the internet
2011-11-01T21:54:51 < Laurenceb_> my local hackspace seems to be a homeless charity
2011-11-01T21:55:23 < Laurenceb_> but they did have a talk by RMS - sadly before i discovered about it
2011-11-01T21:55:28 < Laurenceb_> or i could have trolled him
2011-11-01T21:55:43 < BrainDamage> I missed a RMS talk in my univ few weeks ago

2011-11-02T18:17:51 < grummund> Anyone done anything with stm32 and USB ?
2011-11-02T18:18:36 < grummund> ..or tried to build the code from UM0424 ?
2011-11-02T18:19:20 < _Shurik_> I haven't gotten to that yet
2011-11-02T18:19:46 < _Shurik_> But I have a dev board with stm32f103rbt6 on it
2011-11-02T18:19:52 < _Shurik_> that should have USB support
2011-11-02T18:19:54 < karlp> not enough days in the week fo rme yet :(
2011-11-02T18:21:12 < Laurenceb> i need SWD working
2011-11-02T18:21:36 < Laurenceb> arduino RF22 code is just blocking forever
2011-11-02T18:23:16 <@jpa-> schedule a timer interrupt and print the PC in the interrupt :)
2011-11-02T18:23:28 < Laurenceb> hmm nice one
2011-11-02T18:23:34 < Laurenceb> i ran out of pins
2011-11-02T18:23:51 < Laurenceb> so the SWD pin is used for the nIRQ
2011-11-02T18:24:02 < Laurenceb> from Si4432
2011-11-02T18:24:05 <@jpa-> i wonder if there is any simple to use GDB stub for stm32 yet
2011-11-02T18:24:18 <@jpa-> i saw a mention somewhere of creating one, but no code included
2011-11-02T18:24:38 < Laurenceb> GDB works for stm32 aiui
2011-11-02T18:24:42 < Laurenceb> with SWD
2011-11-02T18:24:57 < karlp> yeah
2011-11-02T18:25:00 < grummund> and JTAG with openOCD
2011-11-02T18:25:11 < Laurenceb> just not with mine
2011-11-02T18:25:17 < Laurenceb> as theres not enough pins XD
2011-11-02T18:25:18 < karlp> are you on windows or linux/mac?
2011-11-02T18:25:24 < Laurenceb> ubuntu :P
2011-11-02T18:25:31 < Laurenceb> of course
2011-11-02T18:25:34 <@jpa-> sure, with SWD
2011-11-02T18:25:42 < karlp> I was using gdbserver from stlink with an SWD lead over to a different board
2011-11-02T18:25:45 < karlp> workd fine.
2011-11-02T18:25:45 <@jpa-> but i want to debug over gprs :)
2011-11-02T18:25:50 < Laurenceb> lmao
2011-11-02T18:26:16 < Laurenceb> i debug with junk dna encoded in sperm
2011-11-02T18:34:31 < grummund> no-one played with USB yet then?
2011-11-02T18:34:57 <@jpa-> i have usb working on stm32, but i didn't code it :)
2011-11-02T18:35:08 <@jpa-> "it came with the firmware" :D
2011-11-02T18:35:22 < grummund> what firmware?
2011-11-02T18:35:31 <@jpa-> dso quad
2011-11-02T18:35:38 < grummund> ah ;)
2011-11-02T18:35:45 <@jpa-> i think it uses stm's fwlib quite directly
2011-11-02T18:37:07  * grummund attempting to build the demo code from UM0424
2011-11-02T18:44:08 < Thorn> I just soldered my first stm32
2011-11-02T18:44:25 < Thorn> board looks like shit but works
2011-11-02T18:46:31 <@jpa-> i'm gonna solder my first one this weekend.. but i have proper boards :) http://koti.kapsi.fi/jpa/stuff/pix/PA250089.JPG
2011-11-02T18:47:29 < Thorn> I've got these http://iteadstudio.com/store/index.php?main_page=product_info&cPath=19_21&products_id=297
2011-11-02T18:48:03 < Thorn> unfortunately having manufactured boards doesn't stop my solder job from looking like shit
2011-11-02T18:48:28 < grummund> what technique did you use for soldering?
2011-11-02T18:49:24 < Thorn> technique? I wouldn't call it that
2011-11-02T18:50:17 < grummund> i've yet to try my hand at a fine pitch lqfp
2011-11-02T18:51:28 < Thorn> 1. put flux on the pads. 2. tin them. discover lots of shorts. 3. drag wick over pads. break two. 4. put them somewhat in place with tweezers. 5. take stm32, put flux on the pins. 6. position (most difficult part).  7. apply solder. 8. use wick for 10-15 minutes until no shorts remain
2011-11-02T18:52:18 < grummund> why tin the pads?
2011-11-02T18:52:37 < Thorn> dunno. it says so in step 2
2011-11-02T18:53:29 <@jpa-> i usually 1. put tin on one pad 2. put the chip in place and solder that one pin in place 3. check alignment 4. apply flux and solder all the pins
2011-11-02T18:53:51 < grummund> http://store.curiousinventor.com/guides/Surface_Mount_Soldering/101
2011-11-02T18:54:08 < Thorn> yes, it's important to solder 2 opposite corners first. forgot that
2011-11-02T18:54:40 < Thorn> Dave Jones had a video tutorial too (including how to break off pads)
2011-11-02T18:54:59 < grummund> but he's annoying :P
2011-11-02T18:55:59 < Thorn> I wish he did more actual tutorials. the rare ones that he does are quite useful
2011-11-02T18:57:19 < grummund> the curiousinventor video is quite good, if you haven't seen it already...
2011-11-02T18:57:48 < Thorn> the chip itself looks more or less well (it wouldn't work otherwise, not much room for error). but 0805 resistors/capacitors are awful
2011-11-02T18:58:21 < karlp> solder tweezers are awesome for those
2011-11-02T18:58:34 < karlp> tin pads, pick up part with hot tweezers, put down, donw.
2011-11-02T18:58:52 < Thorn> also hot air or a reflow oven
2011-11-02T18:59:27 < Thorn> $$$$$
2011-11-02T18:59:49 < karlp> someone here had a nice link to using a garden fork to hold down parts while you soldered them
2011-11-02T18:59:59 < karlp> looked like it worked rpetty well, especially for things like resistors and caps
2011-11-02T19:07:19 < Thorn> that video is indeed quite good, thanks
2011-11-02T19:11:04 < Thorn> one good thing about soldering your own boards is being able to use whatever led colors you want.

2011-11-02T22:10:24 < Laurenceb_> its just flashing like a christmas tree atm XD
2011-11-02T22:10:34 < Laurenceb_> too many flashing leds
2011-11-02T22:10:44 < CheBuzz> It's purtee
2011-11-02T22:11:03 <+Steffanx> Christmas tree Laurenceb .. come on
2011-11-02T22:11:16 <+Steffanx> Be patient
2011-11-02T22:11:41 < CheBuzz> If you want to use stlink with the F4 however, you need to use jnosky's repo until his changes get merged into texane's: https://github.com/texane/stlink/network
2011-11-02T22:11:53 < BrainDamage> CheBuzz: I'm using stlink for the vl
2011-11-02T22:11:59 < BrainDamage> I wanted to know about the f4
2011-11-02T22:12:08 < CheBuzz> Yes, I am using stlink for the F4
2011-11-02T22:12:20 < Laurenceb_> im busy with other projects - will try later with the stlink
2011-11-02T22:12:26 <+Steffanx> st-link from texane sucks for the VL :P
2011-11-02T22:12:28 < Laurenceb_> discovery just arrived
2011-11-02T22:14:15 < CheBuzz> It's slow for me, but it works.  Flashing a 4kb chunk takes about 5 seconds, so if you are flashing a large file very often, you'll be pulling out hair before too long.
2011-11-02T22:15:05 <+Steffanx> And it doesn't support os x CheBuzz :P
2011-11-02T22:15:22 <+Steffanx> And indeed, i HATE it when i have to wait :P
2011-11-02T22:15:30 < Laurenceb_> K bytes ?
2011-11-02T22:15:31 < CheBuzz> That I can't say.  But BrainDamage asked about Linux so that's what I was referring to.
2011-11-02T22:15:40 < Laurenceb_> hmm thats quite slow
2011-11-02T22:15:49 <+Steffanx> I can CheBuzz
2011-11-02T22:16:03 < CheBuzz> Yes it is.
2011-11-02T22:17:09 < CheBuzz> Is there a better alternative?
2011-11-02T22:17:22 < karlp> everything for the VL sucks
2011-11-02T22:17:29 <+Steffanx> Reflash the st-link fw with the versaloon firmware
2011-11-02T22:18:01 < karlp> stlinks flashing perf could probably be vastly improved by some reading of the flash programming manuals
2011-11-02T22:18:11 < CheBuzz> Are you referring to the SW running on the F103CB chip?
2011-11-02T22:18:22 < BrainDamage> yes, you can reflash the F103 chip
2011-11-02T22:18:27 <+Steffanx> Yeah
2011-11-02T22:18:43 < CheBuzz> But then would I need a versaloon programmer?
2011-11-02T22:18:53 <+Steffanx> You need another st-link/programmer
2011-11-02T22:19:19 <+Steffanx> So you just replace the original fw of that f103 with other one :)
2011-11-02T22:19:48 <+Steffanx> It's irreversible afaik
2011-11-02T22:19:55 < CheBuzz> I have an FT2232-based JTAG board.
2011-11-02T22:20:01 < BrainDamage> versaloon, unlike stlink, it's supported by openocd
2011-11-02T22:20:14 < Tom_itx> jpa- you can always go to that directory and get previous days logs
2011-11-02T22:20:15 <+Steffanx> You need swd CheBuzz
2011-11-02T22:20:56 <+Steffanx> Had some time to read the license/blablalba documents from cdiweb yet Tom_itx ? :)
2011-11-02T22:20:56 < karlp> or, wait a while (whoe knows when) and stlink will be supported by openocd as well
2011-11-02T22:21:10 < CheBuzz> But honestly it's probably too much work.  stlink may be slow, but it's fine for my purposes as I am just using the F4 Discovery to begin the software dev process while I wait for my prototype PCBs to come in.
2011-11-02T22:21:11 < karlp> probably starting with stlinkv2 though, because no-one likes working with the stlink v1
2011-11-02T22:21:14 <@jpa-> Tom_itx: but if i haven't explained much about the board at all, it won't be in any log :)

2011-11-02T22:22:52 < Laurenceb_> can you grab the stlink firmware image off the stm32f103 on the F4discover board?

2011-11-02T22:23:11 <+Steffanx> I'm not married too young :P
2011-11-02T22:24:03 < Tom_itx> jpa- you make those?
2011-11-02T22:26:15 <@jpa-> yeah, my first board i ordered from factory :)
2011-11-02T22:26:34 < Tom_itx> where did you order from?
2011-11-02T22:26:50 <@jpa-> seeed
2011-11-02T22:27:09 < Tom_itx> their quality is fair
2011-11-02T22:27:35 <@jpa-> yeah, the 0.3mm vias are great
2011-11-02T22:27:58 <+Steffanx> seeed isn't that bad :)
2011-11-02T22:28:15 < Tom_itx> not as bad as that other place
2011-11-02T22:28:22 < Tom_itx> itead or whatever
2011-11-02T22:28:24 <+Steffanx> itead?
2011-11-02T22:28:34 <+Steffanx> Don't they use the same manufacturer?
2011-11-02T22:29:01 <@jpa-> i think they are the same
2011-11-02T22:29:13 <@jpa-> the specs are the same, the price is the same
2011-11-02T22:29:16 < Tom_itx> i dunno but the quality control isn't as good
2011-11-02T22:29:42 <+Steffanx> I prefer seeed .. at least the website looks 1000 times more professional
2011-11-02T22:30:12 <+Steffanx> *imho
2011-11-02T22:30:21 < Tom_itx> so apparently i have the right ver of stlink for the F4?
2011-11-02T22:30:44 <+Steffanx> The F4 has version 2
2011-11-02T22:30:48 <+Steffanx> Which is the 'best'
2011-11-02T22:31:15 < Tom_itx> from texane or other?
2011-11-02T22:31:48 <+Steffanx> I think there went something wrong in our conversation
2011-11-02T22:32:02 < Tom_itx> there did?
2011-11-02T22:32:23 < karlp> allegedly you can't flash with the standard texane version
2011-11-02T22:32:26 < karlp> you can only run from sram
2011-11-02T22:32:29 <+Steffanx> The ST-LINK is the programmer part of the discovery board. That Texane ST-LINKS is just a utility to talk with that part
2011-11-02T22:32:32 < Tom_itx> i was asking about this one : https://github.com/texane/stlink/network
2011-11-02T22:33:06 <+Steffanx> They should change the name of that tool imho :P
2011-11-02T22:33:11 <+Steffanx> st-linktool or something like that
2011-11-02T22:33:13 < Tom_itx> i need to install ubuntu again and start afresh i think
2011-11-02T22:33:21 <+Steffanx> Why?
2011-11-02T22:34:01 < Tom_itx> i might switch to the ssd, haven't decided just yet
2011-11-02T22:34:05 < karlp> Steffanx: or, just kill the tool, if the device gets supported in openocd, it has no further purpose right?
2011-11-02T22:34:23 < Tom_itx> is it supported there yet?
2011-11-02T22:34:27 < karlp> nope :)
2011-11-02T22:34:32 < karlp> one day (tm)
2011-11-02T22:34:36 <+Steffanx> Are there plans for it ?
2011-11-02T22:34:38 < Tom_itx> 0.5.0?
2011-11-02T22:34:39 < karlp> sure!
2011-11-02T22:34:42 <+Steffanx> as sin REAL plans
2011-11-02T22:34:46 <+Steffanx> *in
2011-11-02T22:34:52 < karlp> it's something I'd like to do, yes.
2011-11-02T22:34:54 <+Steffanx> More than just 'ideas'
2011-11-02T22:34:55 < Tom_itx> or is that not an official release
2011-11-02T22:35:02 < karlp> I have no started on it.
2011-11-02T22:35:16 <+Steffanx> Most of my projects end there…. in the 'i have an idea'-phase :P
2011-11-02T22:35:17 < karlp> I was planning on trying to get the VL boards to work better first, ie, on macosx
2011-11-02T22:35:44 < karlp> but given how much that irritates me, and that I can use teh stlinkv2 to program the VL board anyway if I really want, I'm not sure how much I care.
2011-11-02T22:35:57 < Tom_itx> karlp what compiler toolchain do you use?
2011-11-02T22:36:16 <+Steffanx> codesourcery :)
2011-11-02T22:36:26 < karlp> codesourcery lite
2011-11-02T22:36:29 < Tom_itx> i got that g++ from them, is that it?
2011-11-02T22:36:35 < karlp> yep
2011-11-02T22:36:51 < Tom_itx> apparently it didn't install properly or something
2011-11-02T22:36:52 <+Steffanx> I used eclipse, just because i'm lazy :P
2011-11-02T22:36:53 < karlp> I also installed it all from scratch on another computer last night, using the summon-arm-toolchain, and it also worked just fine
2011-11-02T22:37:06 < Tom_itx> Steffanx how do you get eclipse to see it?
2011-11-02T22:37:22 < Tom_itx> got a link for that one?
2011-11-02T22:37:27 <+Steffanx> I used a tutorial (which is actually meant for windows)
2011-11-02T22:37:49 < Tom_itx> i started one and it said to add stuff to the blacklist
2011-11-02T22:37:57 < Tom_itx> which makes me wonder
2011-11-02T22:38:12 <+Steffanx> blacklist :S
2011-11-02T22:38:36 <+Steffanx> My 'stuff' is based on this https://sites.google.com/site/stm32discovery/open-source-development-with-the-stm32-discovery/setting-up-eclipse-for-stm32-discovery-development
2011-11-02T22:38:41 < karlp> yeah, that odev one looked really dodgy
2011-11-02T22:38:49 < karlp> blacksing _ALL_ cdc-acm devices
2011-11-02T22:38:55 < Tom_itx> i think i'll pass on it for now
2011-11-02T22:39:36 <+Steffanx> lol karlp ?
2011-11-02T22:39:38 <+Steffanx> :S
2011-11-02T22:40:49 < Tom_itx> i think i'll go thru that later Steffanx
2011-11-02T22:41:06 <+Steffanx> Good luck
2011-11-02T22:41:15 < Tom_itx> did you get it to work?
2011-11-02T22:41:20 <+Steffanx> i'm not sure if that linker file works for the f4 ..
2011-11-02T22:41:33 <+Steffanx> And what you have to change to compile for the f4
2011-11-02T22:42:18 < Tom_itx> so another wasted evening?
2011-11-02T22:42:31 <+Steffanx> I guess so
2011-11-02T22:43:16 < CheBuzz> Tom_itx: libopencm3 is working on the F4 Discovery if you are looking for toolsets.
2011-11-02T22:43:20 <+Steffanx> It took me a while to make it functional, just because i forgot to read one important thing
2011-11-02T22:43:34 < Tom_itx> CheBuzz, link?
2011-11-02T22:43:59 < Tom_itx> Steffanx you forgot to read the directions?
2011-11-02T22:44:02 < CheBuzz> http://sourceforge.net/projects/libopencm3/
2011-11-02T22:44:14 <+Steffanx> Something that's more clear now Tom_itx
2011-11-02T22:44:18 <+Steffanx> A Eclipse bug related thing
2011-11-02T22:44:37 < Tom_itx> i crashed that before i ever used it
2011-11-02T22:44:42 < Tom_itx> i'm not impressed
2011-11-02T22:44:55 <+Steffanx> An very old version?
2011-11-02T22:45:06 < Tom_itx> i don't think so
2011-11-02T22:45:07 <+Steffanx> -n
2011-11-02T22:45:14 <+Steffanx> Then it was a pebkac :P
2011-11-02T22:45:26 < Tom_itx> i don't think so
2011-11-02T22:45:31 <+Steffanx> Ok
2011-11-02T22:46:08 < Tom_itx> indigo
2011-11-02T22:46:12 < Tom_itx> is that the wrong one?
2011-11-02T22:47:11 < Tom_itx> 2011 09 16
2011-11-02T22:52:14 < karlp> indeigo is probably a good choice
2011-11-02T22:52:22 < karlp> it's the latest
2011-11-02T22:56:11 < Tom_itx> so how many in here have the discovery board and how many have something else?
2011-11-02T22:56:49  * grummund has the Olimex H103 board
2011-11-02T22:57:15  * Steffanx has no board
2011-11-02T22:57:25 <+Steffanx> Except the stm32vl discovery
2011-11-02T23:02:03 < karlp> I have a VL and an L discovery board
2011-11-02T23:08:58 < Thorn> this iteadstusio board has a pin header block between the mcu and max3232, you can connect one of 2 uarts to the rs-232 port and also do loopback. nice idea

2011-11-03T20:35:13 <+Steffanx> ure
2011-11-03T20:44:14 < karlp> is that the v8 64 bit stuff?
2011-11-03T20:48:24 <+Steffanx> yeah

2011-11-03T21:55:49 <+Steffanx> F103, SRAM :(
2011-11-03T21:56:10 <+Steffanx> I prefer this one Thorn http://www.ebay.com/itm/STM32F207ZG-module-HY-STM32F2xxCore144-Core-Dev-Board-/170707449711?pt=LH_DefaultDomain_0&hash=item27bef4f76f
2011-11-03T21:56:44 <+Steffanx> It's cheaper, also SRAM, but a F2 :)
2011-11-03T21:57:53 < Laurenceb_> could that run linux?
2011-11-03T21:58:12 <+Steffanx> uclinux perhaps?
2011-11-03T21:58:54 <+Steffanx> I want a raspberry pi :)
2011-11-03T21:58:59 <+Steffanx> That one CAN run linux very well
2011-11-03T22:00:00 < Thorn> how come that cortex-a chips are advertised as starting from $5 but most boards are well beyond $100?
2011-11-03T22:00:16 <+Steffanx> SRAM is expensive?
2011-11-03T22:00:21 <+Steffanx> The board too?
2011-11-03T22:00:24 <+Steffanx> Profit?
2011-11-03T22:00:56 < Thorn> I'm 99.9% sure they use sdram. also boards are probably 4 layer
2011-11-03T22:01:10 <+Steffanx> Oh, i can't read again sorry
2011-11-03T22:01:21 <+Steffanx> cortex-a really sells for $5?!
2011-11-03T22:01:43 < Thorn> TI press releases keep repeating that
2011-11-03T22:01:50 < karlp> how do people think that double pin rows like that are breadboardable?
2011-11-03T22:01:56 <+Steffanx> Press releases :)
2011-11-03T22:02:02 < karlp> perf board perhaps
2011-11-03T22:02:02 <+Steffanx> When oyu buy 100.000?
2011-11-03T22:02:11 <+Steffanx> I HATE that too karlp
2011-11-03T22:02:26 < karlp> it's completely useless
2011-11-03T22:02:41 < karlp> it's one of the few times when arduino style sockets are more useful than the pin headers
2011-11-03T22:03:08 < Thorn> many boards come with no headers installed
2011-11-03T22:04:50 < karlp> mouser sells A8s, from freescale, but they're 35€ and up in singles
2011-11-03T22:06:23 < Laurenceb_> yeah im really annoyed my F4discovery is populated
2011-11-03T22:06:37 < Laurenceb_> double pin headers :(

2011-11-03T23:18:01 < Laurenceb_> XD
2011-11-03T23:21:21 < karlp> NonaSuomy: what?
2011-11-03T23:22:06 < NonaSuomy> <karl_> TeknoJuce: it comes up from time to time, but I think the common answer is one of a) how much money do you have, and b) do you have any existing tools from any of them?
2011-11-03T23:33:54 < karlp> how long ago was that? what were you asking?

2011-11-03T23:35:27 < NonaSuomy> <TeknoJuce> whats the most n00b friendly tool chain for stm32f4 development toolchains:

2011-11-03T23:36:30 < Thorn> MDK-ARM is >$6K is it not?
2011-11-03T23:36:34 < Laurenceb_> if you are rich
2011-11-03T23:37:29 < NonaSuomy> dont get why any company would make a kit to compete with arduino and make it so convoluted and pricey to piss around with
2011-11-03T23:38:42 < Thorn> what kit is that?
2011-11-03T23:39:50 < NonaSuomy> stm32f4
2011-11-03T23:40:23 < Thorn> it's a microcontroller family, not a kit
2011-11-03T23:40:45 < NonaSuomy> stm32f4-discovery
2011-11-03T23:41:20 < NonaSuomy> discovery of the pain in your wallet apparently
2011-11-03T23:41:22 < Thorn> I really doubt it's competing with arduino
2011-11-03T23:41:41 < Tom_itx> maybe it's me but i find setting up the tools to be a pita
2011-11-03T23:42:13 < NonaSuomy> when something has a name like that seems to me like thats what they are doing
2011-11-03T23:42:13 < Tom_itx> but then i haven't tried the ones they recomended yet either
2011-11-03T23:42:36 < Thorn> I heard good things about crossworks ($150 non-commercial license) though never tried it myself
2011-11-03T23:42:38 < Tom_itx> stm32f4-Mystery
2011-11-03T23:42:40 < NonaSuomy> they should have called it stm32f4-electronicengineering
2011-11-03T23:43:24 < NonaSuomy> I have two of these now and can't do anything with them
2011-11-03T23:43:46 < NonaSuomy> the page was all butterfly's and rainbows
2011-11-03T23:43:59 < NonaSuomy> to me that doesnt screen non-n00b friendly
2011-11-03T23:44:16 < NonaSuomy> scream
2011-11-03T23:46:48 < NonaSuomy> Quote from page "The STM32F4DISCOVERY helps you to discover the STM32F4 high-performance features and to develop your applications easily. It includes everything required for beginners and experienced users to get started quickly. "
2011-11-03T23:47:11 < NonaSuomy> it included nothing but the board
2011-11-03T23:48:47 < grummund> send it back for a refund
2011-11-03T23:49:17 < NonaSuomy> i want to use it though just dont know how when alls they did was list those tools that are fortunes
2011-11-03T23:50:44 < NonaSuomy> it didnt even include any usb cables which it requires both a mini usb and a micro usb to utilize it
2011-11-03T23:50:45 < Thorn> well makefiles work too, and the actual toolchain is free
2011-11-03T23:52:27 < NonaSuomy> where do you get the ST-Link/V2 driver
2011-11-03T23:52:51 < karlp> if you're on windows, like they expected everyone to be, there's a stlink tool on their website that can flash things
2011-11-03T23:52:59 < karlp> they link to promo versions of the windows tools
2011-11-03T23:53:08 < karlp> you only need one usb mini cable
2011-11-03T23:53:11 < NonaSuomy> I plug it in and it askes for that, but when I read the documentation it says you need to download one of those expensive packages
2011-11-03T23:53:25 < karlp> and if you don't have a usb mini lying around, what have you been doing with the last 10 years?
2011-11-03T23:54:05 < NonaSuomy> it has mini on the left side and micro on the right side
2011-11-03T23:54:15 < karlp> right, but only one of them is for programming and power
2011-11-03T23:54:22 < karlp> the other is because it's a USB OTG device.
2011-11-03T23:55:10 < NonaSuomy> so do you know a link to get the driver for the mini st-link/v2 driver? yet to find it on there site
2011-11-03T23:56:28 < NonaSuomy> as when I plug in the mini cable it fails to install the driver for the embedded st-link/v2

--- Day changed Fri Nov 04 2011
2011-11-04T00:00:53 < NonaSuomy> hmm windows xp that might have bad news written all over it
2011-11-04T00:01:12  * karlp shrugs
2011-11-04T00:01:15 < NonaSuomy> wonder if that /v2 might be different
2011-11-04T00:01:17 < karlp> I'm not on windows
2011-11-04T00:02:04 < Laurenceb_> ive just got F4discovery working on ubuntu
2011-11-04T00:02:11 < Laurenceb_> with SWD
2011-11-04T00:02:35 < karlp> f4 on linux should work ok.
2011-11-04T00:02:40 < Laurenceb_> it does
2011-11-04T00:03:00 < karlp> how are you connected again? directly to the SWD pins on PA13 and 14 or something?
2011-11-04T00:03:12 < Thorn> Laurenceb_: what hardware/software do you use for swd?
2011-11-04T00:03:22 < Laurenceb_> just the board
2011-11-04T00:03:40 < karlp> yeah, the onboard stlinkv2 should work just fine with texane's stlink on ubuntu
2011-11-04T00:03:42 < Laurenceb_> im using the texane code from github, then GDB from codesourcery and nemiver
2011-11-04T00:03:56 < karlp> some people are saying there's problems with flashing though
2011-11-04T00:04:06 < Laurenceb_> havent tried yet
2011-11-04T00:04:19 < Laurenceb_> wait.. i never setup the correct GDB in nemiver
2011-11-04T00:04:20 < Laurenceb_> odd
2011-11-04T00:05:24 < Laurenceb_> yeah its using standard gdb
2011-11-04T00:05:39 < karlp> standard gdb, as in arm-none-eabi-gdb?
2011-11-04T00:07:37 < grummund> /usr/lib/gcc/arm-elf/4.5.2/../../../../arm-elf/bin/ld: error: ../../Libraries/CMSIS/CM3/DeviceSupport/ST/STM32F10x/startup/TrueSTUDIO/startup_stm32f10x_md.o uses hardware FP, whereas vcomdemo.elf uses software FP
2011-11-04T00:07:38 < Laurenceb_> /usr/bin/gdb
2011-11-04T00:08:03 < Laurenceb_> ill need to set that up if im to do proper debugging
2011-11-04T00:08:07 < karlp> /usr/bin/gdb won't work with the gdbserver provided in stlink.
2011-11-04T00:08:33  * grummund has seen this error before but can't remember what the probem is
2011-11-04T00:08:47 < karlp> grummund: wrong arch targets?
2011-11-04T00:08:55 < NonaSuomy> so if I run a ubuntu build it will pick up the st-link right away?
2011-11-04T00:09:01 < NonaSuomy> over mini usb?
2011-11-04T00:09:35 < Laurenceb_> hmm wtf
2011-11-04T00:09:47 < Laurenceb_> its certainly working
2011-11-04T00:09:58 -!- district [district@2607:f2f8:20c0::69] has joined ##stm32
2011-11-04T00:10:02 < Laurenceb_> but i can see /usr/bin/gdb has been started by nemiver
2011-11-04T00:10:04 < karlp> odd.
2011-11-04T00:10:22 < Laurenceb_> doesnt look like i can configure which gdb
2011-11-04T00:10:29 < karlp> perhaps your usr/bin/gdb has some magical multiarch stuff mine oesn't have
2011-11-04T00:10:40 < Laurenceb_> atm im just mucking about with the registers and stuff
2011-11-04T00:10:45 < grummund> karlp: something like that
2011-11-04T00:10:46 < Laurenceb_> havent tried reflashing it
2011-11-04T00:10:52 < Laurenceb_> its working fine
2011-11-04T00:10:56 < karlp> if I try and use normal gdb it goes pearshaped trying to read the arm.elf file and expected x86 registers
2011-11-04T00:11:07 < karlp> so you can load things like the blink.elf and run from SRAM?
2011-11-04T00:11:14 < Laurenceb_> hmm but some of my register names are wrong
2011-11-04T00:11:20 < Laurenceb_> havent tried
2011-11-04T00:11:28 < NonaSuomy> aye theres the windows 7 driver http://www.st.com/internet/evalboard/product/251168.jsp
2011-11-04T00:11:32 < Laurenceb_> its definately thinking its x86 i think
2011-11-04T00:12:02 < Laurenceb_> doesnt look like nemiver has an option to configure which gdb :(
2011-11-04T00:12:36 < BrainDamage> edit -> preferences -> debugger -> gdb binart
2011-11-04T00:19:47 < grummund> you need a matching gdb for the toolchain

2011-11-04T00:29:34 < Tom_itx> they made a board for hackers and gave it away to us but what they failed to realize was most of the hackers use linux
2011-11-04T00:30:29 < Tom_itx> at least when motorola sent me an eval board i got a CD AND serial cable with it
2011-11-04T00:30:39 < Tom_itx> i kept the cable and tossed the rest
2011-11-04T00:30:53 < Tom_itx> i didn't even get a cable to keep with this
2011-11-04T00:31:02 < Laurenceb_> oh dear
2011-11-04T00:31:20 < Laurenceb_> ubuntu dependency hell
2011-11-04T00:31:30 < Laurenceb_> i cant upgrade nemiver
2011-11-04T00:31:35 < Tom_itx> Laurenceb do you have a working toolchain?
2011-11-04T00:32:25 < Laurenceb_> yes
2011-11-04T00:32:37 < Laurenceb_> codesourcery - nice and simple
2011-11-04T00:32:39 < Tom_itx> you should post what you did somewhere
2011-11-04T00:32:48 < Laurenceb_> linker scripts and stuff are epic pita
2011-11-04T00:32:52 < Tom_itx> from Mentor Graphics?
2011-11-04T00:32:59 < Laurenceb_> its on my github - search for Laurenceb
2011-11-04T00:33:00 < Laurenceb_> yes
2011-11-04T00:33:20 < Tom_itx> i installed that
2011-11-04T00:33:29  * karlp grumbles about stupid stupid usb mass storage 
2011-11-04T00:33:46 < Tom_itx> good thing christmas is coming up soon
2011-11-04T00:33:57 < Tom_itx> i can at least hang it on the tree and watch the leds blink
2011-11-04T00:34:14 <+Steffanx> :P
2011-11-04T00:34:22 < Laurenceb_> haha
2011-11-04T00:34:26 <+Steffanx> Get a tree with a usb port Tom_itx
2011-11-04T00:34:32 < Laurenceb_> yeah theres _way_ too many flashing leds
2011-11-04T00:34:48 < grummund> lol Tom_itx
2011-11-04T00:34:59 < Laurenceb_> looks like and arduinogasm
2011-11-04T00:35:30 < Tom_itx> i haven't given up, just noting frustration with an introductory tool
2011-11-04T00:35:42  * grummund spent days getting the toolchain to run, no reason it should be easier for anyone else :P
2011-11-04T00:35:52 < Laurenceb_> when i was an undergrad my uni put flashing blue leds all over the front entrance :(
2011-11-04T00:35:58 <+Steffanx> :)
2011-11-04T00:36:09 < grummund> Tom_itx: which toolchain do you have?
2011-11-04T00:36:15 <+Steffanx> Poor you Laurenceb
2011-11-04T00:36:17 < Tom_itx> several :)
2011-11-04T00:36:34 < Tom_itx> grummund, i downloaded the Mentor Graphics and installed it
2011-11-04T00:36:45 < Tom_itx> and was trying to interface it with eclipse
2011-11-04T00:36:51 < karlp> I think it's more that the rest of the tools, like the linker scripts and stdlibs, are no-where near as easy to use, unified and well documented as say, avr-libc

2011-11-04T00:37:31 < Tom_itx> grummund using that as a somewhat guide
2011-11-04T00:37:49 < grummund> Tom_itx: what IDE do you use for avr?
2011-11-04T00:37:53 < Laurenceb_> just install codesourcery
2011-11-04T00:38:01 < Laurenceb_> then grab my github and try making
2011-11-04T00:38:05 < Tom_itx> grummund, i use notepad
2011-11-04T00:38:06 < Tom_itx> and make
2011-11-04T00:38:12 < grummund> use that then
2011-11-04T00:38:15 < Tom_itx> but i don't have a good make for this yet
2011-11-04T00:38:21 < BrainDamage> under arch, I just installed the gnu arm eabi, and gave me gcc 4.6
2011-11-04T00:38:31 < Tom_itx> and studio for debugging once in a great while
2011-11-04T00:38:34 < BrainDamage> err, arm eab none
2011-11-04T00:38:35 < BrainDamage> sorry
2011-11-04T00:38:42 < BrainDamage> the gnu one is for targeting linux
2011-11-04T00:40:22 < karlp> hmm, I thought I was making progress.  Yesterday I could only send a single request to the stlinkv1 on the VL board, before having to unplug and replug.
2011-11-04T00:40:30 < karlp> Now I can send more, but only "version" and "status"
2011-11-04T00:40:39 <+Steffanx> Waow!
2011-11-04T00:40:40 < BrainDamage> your code?
2011-11-04T00:40:40 < karlp> any attempt to leave DFU mode just fails.
2011-11-04T00:41:17 < karlp> this is trying to remove the sg-utils dependency from stlink, so it works on OSX as well.
2011-11-04T00:41:23 < karlp> giving me some headaches :|
2011-11-04T00:41:58 < karlp> doesn't help that I didn't write the original code, so I don't know where some of the magic is coming from.
2011-11-04T00:42:13 < grummund> Tom_itx: so you have sample code, but no Makefile?
2011-11-04T00:42:23 < Tom_itx> i have their sample code
2011-11-04T00:42:29 < Tom_itx> i'm sure they have makefiles
2011-11-04T00:42:46 < Tom_itx> but likely set up for windows tools
2011-11-04T00:43:08 < NonaSuomy> 18:35:43 : Connected via SWD.
2011-11-04T00:43:08 < NonaSuomy> 18:35:43 : Device ID:0x411
2011-11-04T00:43:08 < NonaSuomy> 18:35:43 : Device family :STM32F4xx
2011-11-04T00:46:58 < karlp> oh, hmm. I wonder if it's because I told usb-storage to ignore the device
2011-11-04T00:47:00 < karlp> blah
2011-11-04T00:47:31 < Tom_itx> anybody use summon-arm-toolchain?
2011-11-04T00:49:10 < karlp> yeah,
2011-11-04T00:49:13 < karlp> worked just fine for me
2011-11-04T00:49:16 < karlp> takes a while though
2011-11-04T00:49:49 < Tom_itx> show me one that doesn't
2011-11-04T00:49:51 < Tom_itx> :)
2011-11-04T00:49:58 < grummund> anyone have an idea why this is failing to link? - http://pastebin.com/TWXsDKhh
2011-11-04T00:51:00 < Laurenceb_> off to insight i go

2011-11-04T00:52:06 <+Steffanx> "uses hardware FP, whereas vcomdemo.elf uses software FP" I had that problem too and i've no idea to fix it grummund
2011-11-04T00:54:59 < karlp> grummund: try "gcc" -dumpspecs, and look at th eline for multilib_defaults:
2011-11-04T00:56:00 < grummund> Steffanx: did you use -nostartfiles, it fixed the error for me before.

2011-11-04T01:05:22 < grummund> btw, the same toolchain and makefile worked ok for a simple led blinker
2011-11-04T01:05:22  * karlp shrugs
2011-11-04T01:05:38 < karlp> I was reading something just recently about how the hard/soft float stuff all played together

2011-11-04T01:07:11  * grummund suspects the problem is it's trying to link with glibc instead of newlib
2011-11-04T01:07:23 < karlp> thanks Steffanx  :)
2011-11-04T01:07:32 < karlp> ooooh yeah.
2011-11-04T01:10:06 < karlp> grummund: this is the page I was reading, but it seems to imply that if you have a "recent" gcc, with proper EABI, this should "just work"

2011-11-04T01:23:45 < grummund> fantastic, i was using startup.s from truestudio to match the linker script from truestudio, but it seems i need startup.s from gcc_ride7
2011-11-04T01:24:04 < grummund> so now it compiles *and* links :)
2011-11-04T01:24:18 < grummund> mission accomplished (for today)

2011-11-04T01:55:30 < Laurenceb_> https://launchpad.net/~gezakovacs/+archive/nemiver
2011-11-04T01:55:39 < Laurenceb_> that worked on ubuntu 10.04LTS
2011-11-04T01:55:52 < Laurenceb_> nemiver is working now with correct gdb
2011-11-04T01:58:38 < Laurenceb_> yeah registers are sane nowq
2011-11-04T01:59:38 < Laurenceb_> i spent ages trying ddd and insight
2011-11-04T01:59:47 < Laurenceb_> this is best by far
2011-11-04T02:07:23 < karlp> was probably bugs in the old v0.7 that was on 10.04.
2011-11-04T02:07:31 < karlp> that actually looks pretty, I might try that out :)
2011-11-04T02:08:44 < Laurenceb_> got 0.8.2 working now
2011-11-04T02:08:49 < Laurenceb_> ram dump works XD
2011-11-04T02:09:20 < Laurenceb_> im not sure if load executable or core file will work
2011-11-04T02:09:44 < Laurenceb_> i need to know what the do first
2011-11-04T02:11:20 < Tom_itx> is that debugger?
2011-11-04T02:12:30 < Laurenceb_> yes
2011-11-04T02:12:36 < BrainDamage> gdb interface
2011-11-04T02:12:40 < karlp> Laurenceb_: you should be able to just "tar ext :4242"
2011-11-04T02:12:44 < karlp> then load blah.elf
2011-11-04T02:12:57 < Laurenceb_> i should probably make some  .bins i know wont fry anything on the board
2011-11-04T02:12:59 < karlp> _if_ the linker maps were set up properly, the gdbserver knows what to do.
2011-11-04T02:13:11 < karlp> there's some nice safe ones in the stlink/examples directory :)
2011-11-04T02:13:16 < karlp> they run from sram by default :)
2011-11-04T02:14:21 < Laurenceb_> for F4 board?
2011-11-04T02:15:04 < karlp> I hope so, but I don't have an f4 board
2011-11-04T02:15:21 < karlp> given that people were complainint that it doesn't write to flash for F4 anyway, it should be safe :)
2011-11-04T02:15:21 < Laurenceb_> i dont think i should try this XD
2011-11-04T02:15:38 < karlp> blink does,
2011-11-04T02:15:42 < Laurenceb_> well serial it is then
2011-11-04T02:15:42 < karlp> that's the example I've used the most
2011-11-04T02:15:54 < karlp> serial?
2011-11-04T02:16:02 < Laurenceb_>  o.bin in /blink?
2011-11-04T02:16:06 < Laurenceb_> serial bootloader
2011-11-04T02:16:10 < karlp> no, run make
2011-11-04T02:16:12 < Laurenceb_> theres python code for that
2011-11-04T02:16:13 < karlp> you should get a blink.elf
2011-11-04T02:16:27 < karlp> o.bin ha sbeen removed in my tree at least
2011-11-04T02:16:30 < Laurenceb_> not sure i have the F4 toolchain setup yet

2011-11-04T02:17:37 < Laurenceb_> odd
2011-11-04T02:17:38 < karlp> I don't suppose anyone here knows how to make netbeans ctrl-click through function pointers?
2011-11-04T02:17:49 < karlp> make CONFIG_STM32F4_BLAH or something
2011-11-04T02:17:53 < karlp> the names are in the makefile
2011-11-04T02:18:06 < karlp> in my tree I just let you press "make" and it builds all three, as they are so simple
2011-11-04T02:18:25 < Laurenceb_> oh
2011-11-04T02:19:14 < Tom_itx> ok time for opinions. which is better for windows? IAR or Keil?
2011-11-04T02:21:06 < Laurenceb_> how do i pass the arguments to make?
2011-11-04T02:21:27 < BrainDamage> edit the makefile
2011-11-04T02:21:37 < BrainDamage> or the makefile variables?
2011-11-04T02:21:45 < Laurenceb_> CONFIG_STM32F4_DISCOVERY needs to be defined
2011-11-04T02:21:47 < BrainDamage> then just make variable=1
2011-11-04T02:21:51 < Laurenceb_> but i suck at makefiles

2011-11-04T02:23:04 < Laurenceb_> its does support M4, but i have an version thats over a year old
2011-11-04T02:23:19 < BrainDamage> since I assume you're using linux
2011-11-04T02:23:31 < BrainDamage> why not just use summon arm toolchain?
2011-11-04T02:23:36 < BrainDamage> just let it grind for a while
2011-11-04T02:24:25 < Laurenceb_> isnt that different to codesourcery?
2011-11-04T02:24:34 < Laurenceb_> codesourcery has a nice math lib
2011-11-04T02:24:46 < BrainDamage> yes, it's normal gcc
2011-11-04T02:24:57 < BrainDamage> with minimal patches
2011-11-04T02:25:28 < Laurenceb_> hmm
2011-11-04T02:26:21 < Laurenceb_> i dont want to screw up my F1 projects
2011-11-04T02:26:30 < Laurenceb_> well here goes...
2011-11-04T02:28:14 < Laurenceb_> blerg its not simple
2011-11-04T02:28:23 < Laurenceb_> im going to sleep and try this tomorrow :P

2011-11-04T02:46:21 < Tom_itx> got a good makefile for it?

2011-11-04T03:08:52 < karlp> not any more!
2011-11-04T03:09:00 < karlp> give me three minutes to cleean up the debugging
2011-11-04T03:09:05 < karlp> I just finished testing it out
2011-11-04T03:09:17 < karlp> you can now just add a quirk to usb-storage to completely ignore it,
2011-11-04T03:09:23 < karlp> and it plugs and goes beautifully now

2011-11-04T03:10:10 < karlp> otherwise another half hour or so and I'll finish tidying up the documentation and debug output
2011-11-04T03:10:23 < BrainDamage> it started now
2011-11-04T03:10:38 < BrainDamage> I reloaded usb storage module with the quirk
2011-11-04T03:11:38 < karlp> which quirk?
2011-11-04T03:11:57 < BrainDamage> the one suggested in the stlink repo page

2011-11-04T04:43:51 < BrainDamage> returning tag keeps incrasing in st-link
2011-11-04T04:44:01 < BrainDamage> and stlink led flashes
2011-11-04T04:44:07 < BrainDamage> but not the other chip's
2011-11-04T04:44:53 < BrainDamage> mmm, the quartz in the F101 looks a bit wobbly, is it same there, or has it been damaged?
2011-11-04T04:45:06  * karlp shrugs
2011-11-04T04:46:00 < BrainDamage> thanks for the help so far btw
2011-11-04T04:46:33 < karlp> I haven't done much of actual help :)
2011-11-04T04:47:12 < BrainDamage> can you tell me if the quartz on the F101 rocks back & forth visibly there if you touch with your finger? :p
2011-11-04T04:48:04 < karlp> on the "discovery" portion of the board you mean? yeah
2011-11-04T04:48:08 < karlp> it's mounted high, and it wobbles
2011-11-04T04:48:45 < BrainDamage> ok, so it's not a mechanical failure here :/
2011-11-04T04:51:55 < karlp> ok, time fo rme to have been in bed.
2011-11-04T04:53:49 < BrainDamage> good night
2011-11-04T04:53:54 < BrainDamage> one thing:
2011-11-04T04:54:07 < BrainDamage> please add the force v1 functionality to the flash utility too
2011-11-04T04:54:18 < BrainDamage> since it seems to fail to reckognize it's a v1 as well
2011-11-04T04:55:28 < karlp> yeah, I want to just get rid of that separate file anyway
2011-11-04T04:55:37 < karlp> just make it an different optiot to st-util
2011-11-04T04:57:01 < karlp> so st-util [-1] for gdb server, and st-util [-1] -W filename | -R <address> [-L lenght]
2011-11-04T04:57:11 < BrainDamage> works for me
2011-11-04T04:57:33 < karlp> one less set of things to build, and have duplicate detection stuff and flash memory mapping
2011-11-04T04:57:41 < Tom_itx> will stlink save hex from the board to file?
2011-11-04T04:57:53 < karlp> it saves a binary at the moment,
2011-11-04T04:58:04 < karlp> not sure much about what restrictions it has
2011-11-04T04:58:05 < Tom_itx> what about IAR or Keil?
2011-11-04T04:58:13 < karlp> to be honest I haven't looked at the flash stuff much
2011-11-04T04:58:33 < karlp> I wanted to get them working, (the VL board was annoying me)
2011-11-04T04:58:35 < Tom_itx> i wanted to save the demo hex before i screw something up
2011-11-04T04:58:56 < karlp> my next plans are to be able to _rebuild_ the "demo" code, from the example code provided by ST,
2011-11-04T04:59:10 < karlp> to run in SRAM, to verify that I can rebuild all their examples
2011-11-04T04:59:19 < karlp> when that works I'll be more inclined to look at flash stuff
2011-11-04T04:59:29 < Tom_itx> mkay
2011-11-04T04:59:49 < karlp> anyway, I've learnt far more about scsi pass through and usb mass storage this week than I ever really wanted to know, and it's far far too late at night (again)
2011-11-04T05:00:15 < karlp> I would be interested to hear how anyone goes with my code on VL boards though. (SRAM only)
2011-11-04T05:00:18  * karlp wav4es
2011-11-04T05:00:39 < BrainDamage> good night

2011-11-04T14:11:55 < karlp> well, I said I was going to have some things done by this afternoon in time for beer and pizza and darts,
2011-11-04T14:11:56 < Laurenceb> does codesourcery have its own math lib?
2011-11-04T14:12:01 < karlp> but now it's going to be close :)
2011-11-04T14:12:11 < karlp> and I still wanted to look at funny things on the web
2011-11-04T14:15:49 <+Steffanx> Whoa, only 149$ Thorn :)
2011-11-04T14:16:25 < Thorn> that's close to beagleboard-xm
2011-11-04T14:16:39 <+Steffanx> And pandaboard
2011-11-04T14:16:59 <+Steffanx> The pandaboard has a multi-core though
2011-11-04T14:17:20 < Thorn> I think this one has better peripherals
2011-11-04T14:17:35 < Laurenceb> pedoboard
2011-11-04T14:17:51 <+Steffanx> Even hdmi
2011-11-04T14:19:07 < Thorn> the freescale i.mx family is interesting in general
2011-11-04T14:19:27 < Thorn> there's also a nvidia tegra dev kit but its price is not humane
2011-11-04T14:19:43 <+Steffanx> Uhm Laurenceb ?!
2011-11-04T14:21:16 < Laurenceb> its the new version of bearboard
2011-11-04T14:30:25 < BrainDamage> not to be sold to the over 12
2011-11-04T14:31:50 < Thorn> ah, I get it. it's the internal code name for arduino
2011-11-04T15:00:59 < Thorn> http://www.actel.com/products/smartfusion/default.aspx
2011-11-04T15:53:40 < district> the markup on those freescale boards is ridiculous in europe :(
2011-11-04T15:54:19 < district> also, why does that lcd cost $350?!
2011-11-04T15:54:55 <+Steffanx> Oh, 149$ without the LCD
2011-11-04T15:55:21 < district> yeah
2011-11-04T15:55:30 <+Steffanx> Pff, that makes it less interesting
2011-11-04T15:55:34 < district> exactly :(
2011-11-04T15:55:51 <+Steffanx> Marketing :9
2011-11-04T15:56:13 < district> LCDs are just ridiculously expensive unless you get them from china on ebay
2011-11-04T15:56:23 < district> (ones that have proper data sheets)
2011-11-04T15:56:56 <+Steffanx> The PSP LCD's are nice and pretty cheap
2011-11-04T15:57:03 < district> they have specs?
2011-11-04T15:57:10 < district> i'm sure i considered that before but was put off for some reason
2011-11-04T15:57:44 <+Steffanx> The screen resolution is quite low
2011-11-04T15:57:59 <+Steffanx> 480 x 272 full colour
2011-11-04T15:58:06 < district> oh, yeah :/
2011-11-04T15:58:41 < Thorn> it's got hdmi & lvds
2011-11-04T15:59:28 < district> sure but like you said earlier, it's not really any different to a beagleboard xm in price and specs
2011-11-04T15:59:48 < district> and presumably no dsp either, which is good fun
2011-11-04T16:01:02 < Thorn> beagleboard has some quirks like ethernet connected via usb
2011-11-04T16:03:08 < district> hmmm, what's that "hdmi card" version?
2011-11-04T16:03:15 < district> (the $49 one)
2011-11-04T16:04:25 < district> oh is that just an add-on?
2011-11-04T16:05:30 < district> ... yep :(
2011-11-04T16:06:06 < Thorn> ah correct, it's got vga onboard
2011-11-04T16:07:11 < district> i am quite tempted by the starter kit though
2011-11-04T16:10:44 < district> urgh, spi/i2c is on the hdmi card
2011-11-04T16:30:57 <+Steffanx> That new beaglebone looks nice
2011-11-04T16:31:05 < district> yeah it's tiny
2011-11-04T16:31:06 <+Steffanx> As in .. small :)
2011-11-04T16:37:22 < Laurenceb> RAGE
2011-11-04T16:37:28 < Laurenceb> F4discovery wont flash
2011-11-04T16:37:37 < Laurenceb> stlink is broken
2011-11-04T16:39:36 < district> isn't that a known problem?
2011-11-04T16:39:58 <+Steffanx> No?
2011-11-04T16:40:48 < district> https://github.com/texane/stlink/issues/12
2011-11-04T16:41:40 <+Steffanx> Argh, they should change the name of that tool
2011-11-04T16:41:49 <+Steffanx> The st-link is the programmer, NOT that tool :)
2011-11-04T16:41:57 < district> haha, indeed
2011-11-04T16:42:11 <+Steffanx> Laurenceb meant the tool?
2011-11-04T16:42:19 < district> i'm guessing so
2011-11-04T16:42:24 < Laurenceb> yes
2011-11-04T16:42:26 < Laurenceb> sorry
2011-11-04T16:45:07 < Laurenceb> looks like its been fixed
2011-11-04T16:45:14 < Laurenceb> but in a fork somewhere...
2011-11-04T16:45:18 < Laurenceb> maybe
2011-11-04T16:45:51 < Laurenceb> "as soon as I get blink flash working, I will push"
2011-11-04T16:45:55 < Laurenceb> grr hurry up
2011-11-04T16:51:49 < karlp> one guy "fixed"
2011-11-04T16:51:55 < karlp> but he included 100000000 other changes
2011-11-04T16:52:11 < Laurenceb> i cant even get sram to work
2011-11-04T16:52:17 < Laurenceb> do i need to remove a jumper?
2011-11-04T16:52:30 < Laurenceb> what doe sPPI do?
2011-11-04T16:53:20 < karlp> it should be a matter of git clone...; make; ./gdbserver/st-util; [separate window] arm-none-eabi-gdb; tar ext :4242; load blink.elf;continue
2011-11-04T16:53:35 < Laurenceb> SHOULD
2011-11-04T16:53:42 < karlp> there's quite a few people reporting that that works, for SRAM for f4
2011-11-04T16:53:50 < karlp> flash I know people are having issues with.
2011-11-04T16:53:55 < Laurenceb> (gdb) load blink.elf
2011-11-04T16:53:55 < Laurenceb> Loading section .text, size 0x3c lma 0x20000000
2011-11-04T16:53:56 < Laurenceb> Load failed
2011-11-04T16:54:17 < karlp> and you made a blink for the f4?
2011-11-04T16:55:27 < Laurenceb> yes
2011-11-04T16:55:40 < karlp> load failed is something I've never even seen before.
2011-11-04T16:55:57 < karlp> I don't know if anything shows up on the console where the gdbserver is running?
2011-11-04T16:56:08 < Laurenceb> nothing in there
2011-11-04T16:56:57 < karlp> you could try my version, https://github.com/karlp/stlink and run the gdbserver with "st-util -2 -v" instead of the fake dummy arguments needed in texanes
2011-11-04T16:57:06 < karlp> it should show more debug output on the gdbserver side
2011-11-04T16:58:00 < karlp> I have no real idea why you get load failed and no-one else does. but if loading sram doesn't work, you have bigger problems than flashing :|
2011-11-04T16:58:14 < Laurenceb> yeah
2011-11-04T16:58:18 < Laurenceb> thanks
2011-11-04T16:59:07 < karlp> Steffanx: though, you are on osx with a VL board right?
2011-11-04T16:59:51 < karlp> I'd love it if you could try my version from github.  I removed the sg-utils dependencies that aren't on osx, and it works nicely on linux still, but I don't have an OSX machine around to check it on.
2011-11-04T17:00:22 < karlp> anyway, I need to get back to work for a little while. no time to play right now :)
2011-11-04T17:01:03 < Laurenceb> ok trying
2011-11-04T17:01:11 < Laurenceb> do i need to change anything in udev?
2011-11-04T17:01:19 < karlp> shouldn't, not for an F4 board
2011-11-04T17:01:22 < Laurenceb> ok
2011-11-04T17:01:28 < Laurenceb> test works so far :P
2011-11-04T17:01:37 < karlp> for 32L and F4, my version only really changes the command line option parsing and the logging
2011-11-04T17:01:58 < karlp> Steffanx: suggest a new name!
2011-11-04T17:02:54 < karlp> tfkastl
2011-11-04T17:03:05 < karlp> tool formerly known as s t link?
2011-11-04T17:03:13 < karlp> tf-kastle!
2011-11-04T17:03:27 < Laurenceb> nice
2011-11-04T17:03:36 < karlp> the fabulous kastle
2011-11-04T17:03:38 < Laurenceb> ok the failure is in gdb
2011-11-04T17:03:47 < Laurenceb> it doesnt like my elf
2011-11-04T17:04:00 < Laurenceb> theres no comms to the stlink
2011-11-04T17:04:05 < Laurenceb> before it fails
2011-11-04T17:07:48 < karlp> I'm sorry to hear that, but I am someone relieved at the same time :)

2011-11-04T17:19:39 < karlp> ok, something's twisted with your toolchain then.
2011-11-04T17:19:42 < karlp> yeah, it should,
2011-11-04T17:20:12 < karlp> can you put blink_F4.elf somewhere for me?
2011-11-04T17:20:22 < karlp> I probably won't get to look at it for a few hours,
2011-11-04T17:20:43 < Laurenceb> its from your example
2011-11-04T17:20:50 < karlp> yeah, but you made it :)
2011-11-04T17:20:50 < Laurenceb> im guessing its an issue with gdb
2011-11-04T17:20:59 < karlp> it's made from my _sources_

2011-11-04T17:56:16 < Laurenceb> the elf
2011-11-04T18:00:02 < karlp> if it's not too much trouble, could you please upload the VL or 32L blink.elf too?
2011-11-04T18:00:11 < karlp> they _should_ be directly runnable on my boards

2011-11-04T18:18:41 <+Steffanx> pastebin.com?
2011-11-04T18:18:50 < Laurenceb> thats ascii
2011-11-04T18:18:56 <+Steffanx> Who cares :P
2011-11-04T18:19:07 <+Steffanx> Some here are pro's
2011-11-04T18:19:27 <+Steffanx> click on that dropbox link, register your account and drop it there? :)
2011-11-04T18:20:07 < karlp> no, it works, but you have to view source to get the real link to the file
2011-11-04T18:20:53 <+Steffanx> oh lol
2011-11-04T18:21:05 < karlp> filedump doens't know how to render the elf as a jpg
2011-11-04T18:21:08 < Laurenceb> yeah
2011-11-04T18:21:10 < karlp> so you don't get the image with it's link
2011-11-04T18:21:18 < karlp> http://www.filedump.net/dumped/blink32lelf1320423336.jpg
2011-11-04T18:21:51 < Laurenceb> yeah then just change to elf
2011-11-04T18:22:01 < Laurenceb> it wont let me upload elf
2011-11-04T18:22:29 < karlp> but it is still using filename rather than mimetype detection :)
2011-11-04T18:22:42 < karlp> so it's almost like they want/know that people will be hiding things there
2011-11-04T18:27:06 < Laurenceb> http://pastebin.com/kd2Vqh2H
2011-11-04T18:49:56 < Laurenceb> any luck with that elf?
2011-11-04T18:51:13 < Laurenceb> oh maybe my linker is wrong
2011-11-04T18:52:09  * Laurenceb _. off
2011-11-04T19:00:41 < Thorn> my f103 apparently hangs when I try to initialize uart4 the same way I do for usart1...3
2011-11-04T19:18:48 < karlp> still at work sorry :)
2011-11-04T19:19:19 < karlp> but that's a good amount of info, I'll see what I can find later on.

2011-11-04T20:33:44 < Thorn> I just found that if you link without -mthumb the program fails (-mcpu=cortex-m3 does not seem to be required but .elf size is different with it). these options aren't documented in the gnu ld manual
2011-11-04T20:35:33 < Thorn> (the link command does not compile anything, only objects are passed to it)
2011-11-04T20:40:08 < Tom_itx> what does mthumb switch do?
2011-11-04T20:40:58 <+Steffanx> The thumb instruction set i guess
2011-11-04T20:41:23 < Tom_itx> still doesn't mean much to me
2011-11-04T20:41:35 < Tom_itx> so much to do, so little time
2011-11-04T20:41:57 < Tom_itx> i installed iar yesterday finally
2011-11-04T20:42:05 < Thorn> http://gcc.gnu.org/onlinedocs/gcc/ARM-Options.html , selects thumb code generation. but that's a compiler switch
2011-11-04T20:42:43 < Tom_itx> is thumb a subset of arm or something?

2011-11-04T20:43:39 < Thorn> no, a different instruction set
2011-11-04T20:44:01 < Thorn> cortex-m only supports thumb2 so this switch is always required
2011-11-04T20:45:24 < Thorn> what's the channel for the gnu toolchain? #gcc? #workingset?

2011-11-04T20:59:00 < Thorn> I see blx vs. bl in calls to c library functions like memset (it crashed on memset call in freertos)
2011-11-04T20:59:42 < Thorn> looks like blx calls with even addresses are the problem

2011-11-04T21:13:18 < Laurenceb_> do i need -DDEBUG in my makefile to debug
2011-11-04T21:22:26 < Thorn> I don't think the stm library uses that anywhere
2011-11-04T21:22:37 < Laurenceb_> ok
2011-11-04T21:22:45 < Laurenceb_> doesnt help me anyway :(
2011-11-04T21:22:52 < Laurenceb_> load still fails
2011-11-04T21:23:33 < Laurenceb_> im not going to get anywhere without some more info on what went wrong
2011-11-04T21:24:09 <@jpa-> heh, stlink caused kernel panic :)
2011-11-04T21:24:13 <+Steffanx> Waow
2011-11-04T21:24:25 < Laurenceb_> lol
2011-11-04T21:24:34 < Laurenceb_> well at least mine isnt that bad
2011-11-04T21:24:41 <+Steffanx> Is there anyone who doesn't have problems with the st-link/st toolchain/st-whatever?!
2011-11-04T21:24:51 <@jpa-> though i had some really old version :)
2011-11-04T21:24:54 <+Steffanx> *st toolchain = gcc
2011-11-04T21:25:01 <@jpa-> Steffanx: not on this channel :)
2011-11-04T21:25:12 <+Steffanx> That's ….. silly :)
2011-11-04T21:25:39 <@jpa-> it worked until now (until ubuntu upgrade, probably)
2011-11-04T21:26:06 < Thorn> that's why I avoid discovery boards
2011-11-04T21:26:35 <@jpa-> what computer stuff *doesn't* give you problems sometimes? :D
2011-11-04T21:26:45 <+Steffanx> http://www.naffets.nl/share/a-20111104-202552.png my STM32F103TB has 128kB Flash and 20kB RAM. So it's a Medium i guess?
2011-11-04T21:27:02 <+Steffanx> medium-density
2011-11-04T21:27:45 <+Steffanx> I want to use the 'pinout' no. 36 so it should have 2x SPI and 2 x i2c . Why-o-why i only see 1 spi in the datasheet?!
2011-11-04T21:27:57 < Laurenceb_> has anyone here got sram write to work on stm32F4discovery?
2011-11-04T21:28:09 < Laurenceb_> if so, which version of GDB?
2011-11-04T21:28:18 < Laurenceb_> im wondering if i have the wrong version
2011-11-04T21:28:45 <+Steffanx> Hmm, it also has only 1 i2c interface
2011-11-04T21:28:54 < Thorn> Steffanx: http://pastebin.com/DDBpPLUU
2011-11-04T21:30:11 <+Steffanx> Yeah, so medium density
2011-11-04T21:31:00 <+Steffanx> There's an SPI2, but not for the VFQFPN36 package
2011-11-04T21:31:13 <+Steffanx> So that table is wrong imo
2011-11-04T21:31:46 <+Steffanx> Oh, i found a better table, which seems to be correct
2011-11-04T21:32:45 <+Steffanx> You guys think it would be a good idea to use an gyro+accelerometer+wireless module on the same SPI-peripheral?
2011-11-04T21:32:53 <+Steffanx> *an = a
2011-11-04T21:33:06 <+Steffanx> (it's for a quadrocopter)
2011-11-04T21:34:03 < BrainDamage> I'd split wireless on a sep bus
2011-11-04T21:34:08 < BrainDamage> to have reliable data rate
2011-11-04T21:34:09 <+Steffanx> impossible :)
2011-11-04T21:34:24 <+Steffanx> Only 1 SPI-peripheral
2011-11-04T21:34:33 < karlp> Laurenceb_: your 32L blink file is a different size to mine, but still works on my 32L board :(
2011-11-04T21:34:43 < Laurenceb_> hmm weird
2011-11-04T21:34:44 < Thorn> calculate time required for data access cycles, add up, multiply by number of accesses per second. if you get >1 second, it's a bad sign.
2011-11-04T21:34:49 < BrainDamage> don't you need to guarantee some hard response time?
2011-11-04T21:34:57 < karlp> one tick, let me give you my F4 file, see if that works...
2011-11-04T21:34:59 < BrainDamage> like due to gusts, etc?
2011-11-04T21:35:08 < BrainDamage> to my knowledge, quadrotors are inherently unstable
2011-11-04T21:35:11 < Laurenceb_> thanks
2011-11-04T21:35:13 < BrainDamage> so you need hard realtime
2011-11-04T21:35:25 <+Steffanx> Yes BrainDamage
2011-11-04T21:36:10 < BrainDamage> you'll need a pretty decent communication scheduling then
2011-11-04T21:36:11 <@jpa-> Steffanx: can you interrupt wireless transfers at any time?
2011-11-04T21:36:31 <@jpa-> (i mean, interrupt the spi comm to wireless module?)
2011-11-04T21:36:35 < karlp> http://palmtree.beeroclock.net/~karlp/stlink_elf_samples.tar.bz2
2011-11-04T21:36:40 <+Steffanx> I think that's not a good idea jpa-
2011-11-04T21:36:50 < Laurenceb_> thanks
2011-11-04T21:36:51 < karlp> Laurenceb_: see if the F4.elf in that from me works. (it also includes yours)
2011-11-04T21:36:54 < Laurenceb_> just testing
2011-11-04T21:37:01 < karlp> it's just the same code, but rebuilt on my machine.
2011-11-04T21:37:33 <@jpa-> Steffanx: ok, then you either need to specify upper limit for length of wireless comm and only do it at specific times (i.e. right after reading gyro & accelerometer)
2011-11-04T21:37:50 <@jpa-> -either
2011-11-04T21:38:30 <+Steffanx> Perhaps i should get one that's a little bigger, or move the gyro+accelemeter the i2c bus, but i wonder if that changes something
2011-11-04T21:38:57 < Laurenceb_> karlp: fails
2011-11-04T21:39:03 < BrainDamage> are the bus totally independent?
2011-11-04T21:39:04 < karlp> Laurenceb_: same way?
2011-11-04T21:39:15 < karlp> the obj-dump of the two elfs are different: http://palmtree.beeroclock.net/~karlp/objdump.diffs.problems.txt
2011-11-04T21:39:15 < Laurenceb_> yes, identical
2011-11-04T21:39:17 < BrainDamage> as in, the registers will fill by themselves trough hw controls/microcode?
2011-11-04T21:39:29 < karlp> something's weird with your toolchain.  You only have the F4 board right?
2011-11-04T21:39:42 < Laurenceb_> yes
2011-11-04T21:39:47 < Laurenceb_> im using codesourcery
2011-11-04T21:40:17 < Laurenceb_> patched gcc 4.5.2
2011-11-04T21:40:37 <+Steffanx> BrainDamage, the spi probably is
2011-11-04T21:40:41 < Laurenceb_> looks like thats not the problem
2011-11-04T21:40:47 <+Steffanx> I never used i2c before
2011-11-04T21:40:49 < Laurenceb_> as your code gives same issue
2011-11-04T21:40:54 <+Steffanx> I always use spi when i can
2011-11-04T21:40:59 -!- _Shurik_ [~alex@64.88.170.43] has left ##stm32 []
2011-11-04T21:41:05 < karlp> yeah, but that takes out my ides :)

2011-11-04T21:41:15 < karlp> I was sort of hoping that your elf wouldn't work on my board :)
2011-11-04T21:41:17 < Laurenceb_> do i need to configure stlink at all?
2011-11-04T21:41:22 < karlp> which would point to your toolchain
2011-11-04T21:41:25 < karlp> I've never had to.
2011-11-04T21:41:32 < karlp> if you ahve the udev rules, or use sudo to run it,
2011-11-04T21:41:39 <+Steffanx> I can get me a 48 pin f103, but that one is 7x7mm and not 6x6
2011-11-04T21:41:46 <+Steffanx> And my space is VERY limited
2011-11-04T21:41:47 < karlp> but it shoudl complain very very quickly when it tries to open the usb device if that was a problem
2011-11-04T21:42:20 < Laurenceb_> <_abc_> okay so you need to also load some arguments into stlink before you start gdb
2011-11-04T21:42:20 < Laurenceb_> <_abc_> because apparently some things can't go through the gdb link
2011-11-04T21:42:20 < Laurenceb_> <_abc_> such as hw platform, cpu type, clock freq. and a few more
2011-11-04T21:42:27 < Laurenceb_> ^is he talking nonsense?
2011-11-04T21:43:11 < karlp> yeah, my gcc is the same: arm-none-eabi-gcc (Sourcery G++ Lite 2011.03-42) 4.5.
2011-11-04T21:43:34 < karlp> but, remember, I've never tried on an F4 :)
2011-11-04T21:43:43 < karlp> perhaps both of us have invalid toolchains for F4 :)
2011-11-04T21:43:53 <+Steffanx> BrainDamage, I really have NO experience with building quadrocopters, so it's more a trial and error
2011-11-04T21:44:01 < Tom_itx> it would be nice to find one that actually worked
2011-11-04T21:44:03 < Laurenceb_> is there a way to get more info from gdb?
2011-11-04T21:44:15 < BrainDamage> Steffanx: make sure you got foam padding on the test ground :p
2011-11-04T21:44:17 <+Steffanx> The windows IDE's work Tom_itx
2011-11-04T21:44:31 < Laurenceb_> doesnt let me know _why_ it failed
2011-11-04T21:44:32 < BrainDamage> inherently unstable can mean power dive into soil
2011-11-04T21:44:33 <+Steffanx> it's not a quadrocopter btw, it's a tricopter :)
2011-11-04T21:44:42 <+Steffanx> And a very small one
2011-11-04T21:44:58 < Tom_itx> Steffanx, i want to be able to save hex back to file
2011-11-04T21:44:59 < BrainDamage> how to dump ram from gdb?
2011-11-04T21:45:11 < Tom_itx> avr does it with no questions
2011-11-04T21:45:26 < BrainDamage> I want to verify wtf is going on on my stm32, and why id doesn't blink :/
2011-11-04T21:45:36 <+Steffanx> What do you mean Tom_itx ? You want to read what's on the target right now?
2011-11-04T21:45:41 < Tom_itx> yes
2011-11-04T21:45:53 <+Steffanx> If yes, that's VERY easy with the st-link utility from st
2011-11-04T21:45:57 <+Steffanx> it's windows only though
2011-11-04T21:46:00 < karlp> Steffanx: if the wireless module has an IRC line, and you run at a decent SPI rate, I wouldn't be concerned about running them all on the same spi bus.
2011-11-04T21:46:11 < karlp> as long as they're all fast :)
2011-11-04T21:46:13 < Tom_itx> Steffanx got a link to the actual file?
2011-11-04T21:46:17 < Thorn> for a hardware control loop you need a control algorithm that's faster than the hardware time constant or you'll get oscillations. or something like that. that's what almost happened on apollo 11 landing
2011-11-04T21:47:02 <+Steffanx> http://www.st.com/internet/com/SOFTWARE_RESOURCES/TOOL/DEVICE_PROGRAMMER/stm32_st-link_utility.zip not sure if that's the right one for the stm32f4 discovery Tom_itx
2011-11-04T21:47:08 < BrainDamage> yes, you'll get a system caled not minimal phase
2011-11-04T21:47:09 < Thorn> I imagine that with very low mass that time constant is going to be really low
2011-11-04T21:47:17 < BrainDamage> the delay will really screw you off
2011-11-04T21:47:31 < Tom_itx> F4 needs v2 driver i think
2011-11-04T21:47:37 <+Steffanx> Thorn, that'll probably my problem. The tri-copter is tiny :)
2011-11-04T21:47:49 <+Steffanx> As in .. 5x5 cm or something like that
2011-11-04T21:47:51 < karlp> Tom_itx: well, mine _does_ work for 32L and VL
2011-11-04T21:47:58 <+Steffanx> I still don't even know if it can fly :)
2011-11-04T21:48:03 < Laurenceb_> so i need to swap a jumper to enable running for SRAM?
2011-11-04T21:48:11 < Laurenceb_>  - cant see how thatd be the issue tho
2011-11-04T21:48:14 <+Steffanx> I probably have to do some tests with some board first
2011-11-04T21:48:19 <+Steffanx> *boards
2011-11-04T21:48:27 < Tom_itx> Steffanx, is that available for linux or is that what all this fuss is about?
2011-11-04T21:48:29 < karlp> Laurenceb_: I have not had to change any jumpers anywhere, and I didn't have to load anything in anywhere else. (on the 32L and 32VL)
2011-11-04T21:48:38 < Laurenceb_> ok
2011-11-04T21:48:41 <+Steffanx> That tool is windows only Tom_itx
2011-11-04T21:49:02 < Tom_itx> so wtf are all these others called 'stlink' about then?
2011-11-04T21:49:03 < BrainDamage> any idea how to dump ram using gdb?
2011-11-04T21:49:08 <+Steffanx> st-link from texane is that buggy windows version
2011-11-04T21:49:24 < Tom_itx> so don't use that one
2011-11-04T21:49:28 <+Steffanx> I know that should change the name
2011-11-04T21:49:38 < Tom_itx> it's damn confusing for sure
2011-11-04T21:49:47 <+Steffanx> ST-link/v1 and v2 = the programmer
2011-11-04T21:49:56 < Tom_itx> then you get several variatons of that for linux and who can keep track
2011-11-04T21:50:00 < Laurenceb_> karlp: so how come i can load to flash
2011-11-04T21:50:01 < karlp> Steffanx: what do you think of tfkastle? (tool formerly known as stlinke)
2011-11-04T21:50:04 < BrainDamage> programmer and debugger
2011-11-04T21:50:13 < Tom_itx> stinkylinky
2011-11-04T21:50:19 <+Steffanx> hehe Tom_itx
2011-11-04T21:50:22 < karlp> Tom_itx:  :)
2011-11-04T21:50:24 < karlp> that's good too
2011-11-04T21:50:26 < Laurenceb_> it just gives an stlink error after a while due to the way F4 flash isnt supported yet
2011-11-04T21:50:28 < BrainDamage> it's both the name of thehardware  software that interface with the stm32
2011-11-04T21:50:35 < karlp> Laurenceb_: you can load to flash with what elf?
2011-11-04T21:50:36 < BrainDamage> so it can get a little confusing
2011-11-04T21:50:38 <+Steffanx> Call it knilts
2011-11-04T21:50:39 < Laurenceb_> but gdb loads the elf and start trying to flash it
2011-11-04T21:50:41 < Laurenceb_> yes
2011-11-04T21:50:46 < Laurenceb_> only it doesnt complete
2011-11-04T21:50:50 <+Steffanx> stlink in reverse :)
2011-11-04T21:50:55 < BrainDamage> stink
2011-11-04T21:51:01 < Laurenceb_> as st-link need modifying to work on F4 flash
2011-11-04T21:51:02 <+Steffanx> No knilts
2011-11-04T21:51:11 < karlp> stinkfree
2011-11-04T21:51:29 < karlp> BrainDamage: what board do you have again?
2011-11-04T21:51:29 <+Steffanx> So how can i force Texane to change the name?
2011-11-04T21:51:37 < BrainDamage> karlp: 32vldiscovery
2011-11-04T21:51:40 < Laurenceb_> karlp: so my point is, gdb loads the elf and starts sending it to stlink for flashing
2011-11-04T21:51:44 < Tom_itx> ban him from earth until he does
2011-11-04T21:51:48 < Laurenceb_> but that never happens if its in sram
2011-11-04T21:52:05 < Laurenceb_> so its got to be something to do with that
2011-11-04T21:52:07 < BrainDamage> I load the .elf in ram ok
2011-11-04T21:52:12 < BrainDamage> send continue
2011-11-04T21:52:21 < BrainDamage> stlink keeps receiving data
2011-11-04T21:52:25 <+Steffanx> I'll ban you with him Tom_itx :)
2011-11-04T21:52:29 < BrainDamage> but the stlink does nothing
2011-11-04T21:52:35 < Tom_itx> tell him it's a violation of the free trade act, copywright laws, patent laws etc and you have a damn expensive lawyer sitting there to pounce on him if he doesn't
2011-11-04T21:52:36 < karlp> BrainDamage: (gdb) dump mem blah 0x20000000 0x20001000
2011-11-04T21:52:48 < karlp> will dump memory to a file
2011-11-04T21:52:52 <+Steffanx> No there is an easier way
2011-11-04T21:52:55 < BrainDamage> k, thanks
2011-11-04T21:52:59 < Laurenceb_> hang on
2011-11-04T21:53:01 <+Steffanx> karlp, force texane to join this channel
2011-11-04T21:53:06 < Laurenceb_> i load gdb, kill then load
2011-11-04T21:53:12 < karlp> he's really not very keen on things  it seems
2011-11-04T21:53:14 < Laurenceb_> iis that ok
2011-11-04T21:53:17 < karlp> I've gotten occasional emails from him
2011-11-04T21:53:22 < karlp> not much else.
2011-11-04T21:53:27 <+Steffanx> So he can see where it goes wrong when you use st-link for both the tool and the programmer
2011-11-04T21:53:41 < karlp> oh, I can just change the name in my fork :)
2011-11-04T21:53:49 < karlp> but we have to come up with a nice one first :)
2011-11-04T21:55:01 < karlp> BrainDamage: so you fire up arm-gdb, connect to sth st-util's gdbserver, and load blink.elf,
2011-11-04T21:55:04 < karlp> and it succeeds?
2011-11-04T21:55:18 < karlp> you type continue, and it appears to be off and running, but never blinks anything?
2011-11-04T21:55:19 < BrainDamage> karlp: ObsessiveCompulsiveDebugger
2011-11-04T21:55:31 < BrainDamage> karlp: correct
2011-11-04T21:55:46 < karlp> are you running latest texane, or my fork?
2011-11-04T21:56:21 < karlp> ie, is it still slow and awkward and lots of kernel messages about resetting the scsi crap?
2011-11-04T21:56:22 <+Steffanx> btw karlp the rf module has an irq line
2011-11-04T21:56:26 <+Steffanx> and runs at max 8mhz
2011-11-04T21:56:37 <+Steffanx> So that shouldn't be a real problem i guess?
2011-11-04T21:56:40 < karlp> probably not.
2011-11-04T21:56:54 < karlp> the wifi's going to  be less of a problem than readin ghte gyro's fast enough anyway isn't it?
2011-11-04T21:57:04 < karlp> I'd still want to run it at full speed :)
2011-11-04T21:57:10 < BrainDamage> running your fork atm, master from yesterday's night
2011-11-04T21:57:13 <+Steffanx> It's nordic-stuff btw, no wifi :)
2011-11-04T21:57:27 < BrainDamage> no, it's sufficiently fast now
2011-11-04T21:57:34 < karlp> except it still doesn't blink :)
2011-11-04T21:57:40 < BrainDamage> correct
2011-11-04T21:58:11 < karlp> can you run the gdbserver with -v -1, and pastebin the entire log it spits out for me please, from start, to after you pressed continue?
2011-11-04T21:58:12 < BrainDamage> the ram's content looks like garbage
2011-11-04T21:58:23 < BrainDamage> sure, one moment
2011-11-04T21:59:02 <+Steffanx> The output rate of the accelerometer is only 1kHz anyway
2011-11-04T21:59:22 < karlp> Steffanx: ? well, then, sharing SPI isn't going to be a problem :)
2011-11-04T21:59:27 <+Steffanx> I guess not
2011-11-04T21:59:31 < karlp> unless you're trying to send live video over the wireless or something :)
2011-11-04T21:59:36 <+Steffanx> No, not really
2011-11-04T21:59:51 <+Steffanx> It's only used to control the copter
2011-11-04T21:59:52 < karlp> (mind you, this is in my absolute, "not a robot person" hand waving advice)
2011-11-04T22:00:51 <+Steffanx> I'm not an expert either :)
2011-11-04T22:00:58 <+Steffanx> Trial and error ftw :)
2011-11-04T22:01:07 < karlp> Steffanx: you should see infinitely scrolling "core status: running" and "Actually sent: 31, returning tag: XXX"
2011-11-04T22:01:13 < karlp> where XXX is continually incrementing
2011-11-04T22:01:30 <+Steffanx> You mean BrainDamage ?
2011-11-04T22:01:31 < BrainDamage> I think you meant me, and yes
2011-11-04T22:01:38 < BrainDamage> I told you last night as well
2011-11-04T22:01:44 < BrainDamage> but I guess you were half asleep
2011-11-04T22:01:54 < karlp> probably :|
2011-11-04T22:01:56 < karlp> sorry,
2011-11-04T22:01:59 < BrainDamage> np
2011-11-04T22:02:00 < BrainDamage> http://www.mediafire.com/?c744jtcylr4f9r1
2011-11-04T22:02:12 < BrainDamage> sorry for the crappy file host
2011-11-04T22:02:23 <+Steffanx> dropbox :)
2011-11-04T22:02:24 < karlp> no worries
2011-11-04T22:03:27 <+Steffanx> I know what we should do instead of messing with this
2011-11-04T22:03:32 <+Steffanx> Reverse engineer the bootloader
2011-11-04T22:03:44 <+Steffanx> So we can reflash it with the versaloon fw
2011-11-04T22:03:53 <+Steffanx> All problems solved
2011-11-04T22:04:04 < karlp> the bootloader, or the app on the stlink portion?
2011-11-04T22:04:29 < karlp> given how many other people it seems to be working for, or we just work out why it doesn't work for anyone on this channel :)
2011-11-04T22:04:32 <+Steffanx> Both karlp
2011-11-04T22:05:32 <+Steffanx> Now you need another programmer to flash the st-link with new fw
2011-11-04T22:05:43 <+Steffanx> It would be nice if we could use the bootloader of the st-link
2011-11-04T22:07:12 < karlp> well, I've successfully used the SWD connector on the 32L board, wired up to the SWD pins on the 32VL board,
2011-11-04T22:07:33 < karlp> and then used "stinkylinkynoblinky" to program into SRAM on the VL board
2011-11-04T22:12:02 < karlp> BrainDamage: your main_sp is busted,
2011-11-04T22:12:06 < karlp> mine points to sram,
2011-11-04T22:12:14 < karlp> yours points to 0xfffffffc
2011-11-04T22:12:36 < karlp> r13, r14 and r15
2011-11-04T22:12:47 < karlp> before you load anything, just when you connect
2011-11-04T22:13:10 < karlp> when you do tar ext :4242, some of the debug output is a register dump
2011-11-04T22:14:00 < karlp> hmm. you said you'd managed to flash this before right?
2011-11-04T22:14:16 < karlp> I wonder if mine works, because the _original_ firmware set up the stack pointer properly at some point,
2011-11-04T22:14:22 < karlp> and I've only loaded into sram
2011-11-04T22:14:35 < karlp> it's quite possible that there's a linker script step missing that sets this up?
2011-11-04T22:15:20 < BrainDamage> mmm
2011-11-04T22:15:23 < karlp> (line 252 in your file)
2011-11-04T22:15:45 < Laurenceb_> karlp: the examples in stlink, where are hte linker scripts?
2011-11-04T22:15:54 < Laurenceb_> or is it all in the makefile
2011-11-04T22:15:59 < karlp> well, from what I was told, to run from sram, all you needed was what was in the makefile
2011-11-04T22:16:05 < karlp> but I'm not a linker script master
2011-11-04T22:16:14 < karlp> I saw my lights blink, and was happy and joyful :)
2011-11-04T22:16:32 < Laurenceb_> heh
2011-11-04T22:16:33 < BrainDamage> the linker contains the memory offsets for the binaries
2011-11-04T22:16:39 < Laurenceb_> ah
2011-11-04T22:16:50 < Laurenceb_> i thing my elf is screwed
2011-11-04T22:17:09 < Laurenceb_> when i swap from 0x08000000 to 0x20000000
2011-11-04T22:17:26 < Laurenceb_> as gdb just gives an error straight away
2011-11-04T22:17:45 < BrainDamage> those are the start addresses of the ram & flash
2011-11-04T22:17:49 < Laurenceb_> instead of talking to the gdbserver as it does with 0x08...
2011-11-04T22:17:51 < Laurenceb_> i know
2011-11-04T22:19:51 < karlp> gdbserver has a memory map built in
2011-11-04T22:20:04 < Laurenceb_> oh
2011-11-04T22:20:29 < Laurenceb_> but yeah its got to be gdb
2011-11-04T22:20:35 < karlp> following this: http://sourceware.org/gdb/gdb-memory-map.dtd
2011-11-04T22:20:47 < Laurenceb_> as with your stlink in verbose mode there was nothing
2011-11-04T22:21:00 < karlp> blinkynolinky makes one of them, based on the chip and core ids
2011-11-04T22:21:01 < Laurenceb_> i loaded the elf and it failed
2011-11-04T22:21:09 < Laurenceb_> nothing was sent to gdbserver
2011-11-04T22:22:44 < Laurenceb_> hmm error in arm-none-eabi-objcopy?
2011-11-04T22:24:12 < Laurenceb_> maybe i should try something other than codesourcery
2011-11-04T22:24:24 < Laurenceb_> or... find someone who has something else to make an elf for me
2011-11-04T22:26:00 < BrainDamage> blinky example for F4 board?
2011-11-04T22:27:49 < BrainDamage> Laurenceb_: try http://www.mediafire.com/?xmg11j7hk11nxan ?
2011-11-04T22:28:01 -!- Irssi: ##stm32: Total of 20 nicks [2 ops, 0 halfops, 1 voices, 17 normal]
2011-11-04T22:29:57 < karlp> BrainDamage: can you perhaps try this: https://github.com/karlp/stlink/tree/ldscripts_test/example/blink
2011-11-04T22:30:03 < Laurenceb_> that yours?
2011-11-04T22:30:11 < Laurenceb_> hehe pronysite
2011-11-04T22:30:16 < karlp> the link script there might set up the stack pointer?
2011-11-04T22:30:32  * karlp shrugs
2011-11-04T22:30:34 < karlp> just a guess.
2011-11-04T22:30:37 < karlp> I'm off to the pub
2011-11-04T22:30:41 < Laurenceb_> ill try this elf
2011-11-04T22:30:42 < karlp> have fun!
2011-11-04T22:30:49 < Laurenceb_> enjoy yourself too XD
2011-11-04T22:30:59 < Laurenceb_> sounds like a warzone round here
2011-11-04T22:31:08 < Laurenceb_> fireworks everywhere
2011-11-04T22:31:18 < BrainDamage> thanks for the help & have fun
2011-11-04T22:31:26 < BrainDamage> here it's just rain, rain & rain
2011-11-04T22:31:40 < karlp> christmas beer is going on tap in 29 minutes
2011-11-04T22:31:40 < BrainDamage> oh, and flood pre-emergency status
2011-11-04T22:31:48 < BrainDamage> I'll stay indoor I think :p
2011-11-04T22:33:25 < Laurenceb_> grr failed
2011-11-04T22:33:35 < Laurenceb_> did you make that with codesourcery?
2011-11-04T22:34:05 < BrainDamage> nope, gcc 4.6
2011-11-04T22:34:11 < BrainDamage> native
2011-11-04T22:34:19 < Laurenceb_> hmm ok thanks
2011-11-04T22:34:27 < Laurenceb_> this is even more perplexing
2011-11-04T22:35:44 < Laurenceb_> is there a way to snoop on localhost traffic?
2011-11-04T22:36:18 < BrainDamage> wireshark?
2011-11-04T22:37:05 <+Steffanx> Can wireshark 'snoop' local traffic
2011-11-04T22:37:21 <+Steffanx> It couldn't when i tried to do that.. a long time ago
2011-11-04T22:37:48 < Thorn> if you're on linux you have a loopback interface
2011-11-04T22:37:58 < Thorn> try sniffing that
2011-11-04T22:38:18 < Laurenceb_> how?
2011-11-04T22:38:24 < Laurenceb_> and yeah im on linux
2011-11-04T22:39:05 < BrainDamage> http://wiki.wireshark.org/CaptureSetup/NetworkMedia
2011-11-04T22:39:11 < Thorn> tcpdump -i lo iirc
2011-11-04T22:39:16 < BrainDamage> it's lo interface
2011-11-04T22:39:24 < Laurenceb_> ok
2011-11-04T22:39:53 < Laurenceb_> do i need the port number?
2011-11-04T22:40:14 < BrainDamage> it helps
2011-11-04T22:40:30 < BrainDamage> will let you filter the tons of data that you're not interested in
2011-11-04T22:40:44 < Laurenceb_> tcpdump -i lo:4242 or something?
2011-11-04T22:40:55 < Thorn> no
2011-11-04T22:41:12 < BrainDamage> -I stands for interface
2011-11-04T22:41:19 < Laurenceb_> i see
2011-11-04T22:41:22 < BrainDamage> it'll be another command, check the manpage
2011-11-04T22:41:39 < Thorn> tcpdump -i lo 'tcp port xxx'
2011-11-04T22:41:49 < Laurenceb_> ah
2011-11-04T22:41:58 < Thorn> or 'ip port xxx' etc
2011-11-04T22:42:04 < Thorn> there's a filter language
2011-11-04T22:42:08 < Laurenceb_> rgith
2011-11-04T22:42:12 < Laurenceb_> ok trying...
2011-11-04T22:46:34 < Laurenceb_> ah there is an exchange with the stlink
2011-11-04T22:46:41 < Laurenceb_> so the stlink is breaking
2011-11-04T22:49:13 < Laurenceb_> http://pastebin.com/ZrxykUSy
2011-11-04T22:55:52 < Laurenceb_> dunno what im looking at
2011-11-04T22:56:26 < Thorn> save the capture in a file and look at it with wireshark
2011-11-04T22:56:40 < Thorn> or simply use wireshark to do the capture
2011-11-04T23:03:29 < Laurenceb_> wireshark needs to connect to eth0
2011-11-04T23:05:49 < Laurenceb_> i dont see how this is useful
2011-11-04T23:08:02 < Laurenceb_> oh it can show usb
2011-11-04T23:08:22 < Laurenceb_> thats useful - so theres so usb traffic when the load elf fails
2011-11-04T23:08:30 < Laurenceb_> s/so/no
2011-11-04T23:31:21 < Laurenceb_>  set *(int *)0x20000000=1

2011-11-04T23:34:05 -!- phantoxe [~destroy@a95-92-92-79.cpe.netcabo.pt] has joined ##stm32
2011-11-04T23:34:23 -!- markamber [43b0d0cb@pdpc/supporter/student/markamber] has joined ##stm32
2011-11-04T23:36:07 < markamber> Anyone here who knows how to program the stm32f4discovery? I would like to modify the default audio playback program to play three different files, depending on what (external, not user) button is pressed and one all stop button. this is for a play at my school where they need the actors to cue the sound effects for a door (creak, doorbell, slam) so it will only play once and stop
2011-11-04T23:37:03 < markamber> this is my first experiance with the stm, but I have programmed arduinios, and much bigger robots and wrote a little computer game, so I have an idea on how to make modifications to code, just not the way to use the stm
2011-11-04T23:37:09 < markamber> or is there a better place to ask this?
2011-11-04T23:37:44 < Laurenceb_> hahahaha
2011-11-04T23:37:57 < Laurenceb_> now if you were reading the scollback....
2011-11-04T23:38:11 < markamber> ?
2011-11-04T23:38:13 < Laurenceb_> can you get what ive been trying to do for the past day
2011-11-04T23:38:17 < Laurenceb_> :P
2011-11-04T23:38:22 < markamber> enlighten me
2011-11-04T23:38:42 < Laurenceb_> how to program the stm32f4discovery
2011-11-04T23:38:44 < Laurenceb_> ^that
2011-11-04T23:38:56 < Laurenceb_> XD
2011-11-04T23:39:12 < markamber> ok, so has anyone helped you? or is this place dead
2011-11-04T23:39:20 < Laurenceb_> no its very much alive
2011-11-04T23:39:27 < Laurenceb_> unlike my stm32F4discovery
2011-11-04T23:39:45 < Laurenceb_> are you on linux/osx or windows?
2011-11-04T23:39:46 < markamber> alive with two people cluless on how to program the stm32
2011-11-04T23:39:53 < Laurenceb_> heh
2011-11-04T23:39:55 < markamber> all three, right now windows
2011-11-04T23:40:04 < markamber> I have linux here and a mac at home
2011-11-04T23:40:11 < Laurenceb_> cool
2011-11-04T23:40:14 < Laurenceb_> ubuntu?
2011-11-04T23:40:21 < Laurenceb_> i can get you as far as ive got
2011-11-04T23:40:27 < markamber> I have that (among others)
2011-11-04T23:40:37 < markamber> I have put the sample program on the device
2011-11-04T23:40:38 < Laurenceb_> ok, which version?
2011-11-04T23:40:44 < Laurenceb_> really?!
2011-11-04T23:40:52 < markamber> the not newest
2011-11-04T23:40:53 < Laurenceb_> ok youve got further than me
2011-11-04T23:40:57 < Tom_itx> using what?
2011-11-04T23:40:58 < Laurenceb_> oh
2011-11-04T23:40:58 < markamber> but I am on windows
2011-11-04T23:41:04 < Laurenceb_> wait
2011-11-04T23:41:11 < Laurenceb_> have you programmed an F4?
2011-11-04T23:41:18 < markamber> no
2011-11-04T23:41:25 < markamber> just put the default stuff on it
2011-11-04T23:41:36 < Laurenceb_> its already on
2011-11-04T23:41:40 < Laurenceb_> what do you mean
2011-11-04T23:41:59 < Laurenceb_> have you reflashe dit
2011-11-04T23:42:20 < markamber> or are you talking about programming as in a pic programmer or programming as in making it blink counter clockwise instead of clockwise programming (like with a text editor)
2011-11-04T23:42:22 < markamber> the latter I have not done
2011-11-04T23:42:30 < Tom_itx> you can supposedly do that with IAR or StM32 Stlink
2011-11-04T23:42:36 < markamber> do you know of any other community, because there must be tons of people using these
2011-11-04T23:42:49 < Laurenceb_> i dont know of another irc
2011-11-04T23:42:52 < markamber> not like arduino, but still at least several more
2011-11-04T23:43:07 < markamber> maybe the people at arduinio know where to go
2011-11-04T23:43:10 < Laurenceb_> well ive got SWD working
2011-11-04T23:43:13 < Laurenceb_> in ubuntu
2011-11-04T23:43:16 < Tom_itx> so you loaded the default hex demo file on the board?
2011-11-04T23:43:19 < Laurenceb_> but i cant write to sram
2011-11-04T23:43:21 < Tom_itx> using windows tools
2011-11-04T23:43:47 < _Shurik_> I've used J-Link with STM32F103 board. Works great
2011-11-04T23:43:52 < markamber> if you use windows just get attolic truestudio lite for stm32, it is free and works right of of the box
2011-11-04T23:44:24 < Tom_itx> what about IAR or Keil?
2011-11-04T23:44:32 < markamber> I am not a fan of doing what is easiest most of the time though, but this is just too confusing to start with, I need something simple
2011-11-04T23:44:35 < markamber> they cost money
2011-11-04T23:44:46 < Tom_itx> not the ones i downloaded
2011-11-04T23:44:56 < Laurenceb_> markamber: SWD works in linux
2011-11-04T23:45:08 < Laurenceb_> but i cant write to sram for some reason
2011-11-04T23:45:17 < Laurenceb_> and flash writing is broken
2011-11-04T23:45:24 < Tom_itx> i just wonder how well they work before i try them
2011-11-04T23:45:52 < markamber> simple question, can anyone here make an led blink when you press an external button on an stm32f4discovery, or any stm32, and can I see that code, I think if I see that I will have everything I will need to make what I want work
2011-11-04T23:46:18 < Laurenceb_> its pretty easy
2011-11-04T23:46:27 < Laurenceb_> i dont have any simple examples, sorry
2011-11-04T23:46:46 < Laurenceb_> st have good examples of the basics
2011-11-04T23:46:46 < markamber> how do I read a button on a certain input then
2011-11-04T23:46:56 < Tom_itx> look at the demo
2011-11-04T23:46:59 < Laurenceb_> using the GPIO stuff in the ST perif lib
2011-11-04T23:47:03 < Laurenceb_> yeah read a demo
2011-11-04T23:47:05 < Tom_itx> to see how they invoke the demo button
2011-11-04T23:47:08 < markamber> what demo, what file?
2011-11-04T23:47:25 < markamber> and are they using a user button or a button attached to one of the leads
2011-11-04T23:47:34 < Laurenceb_> st have a load of demos as zip files on their site
2011-11-04T23:47:43 < markamber> I have that too
2011-11-04T23:48:00 < markamber> I am pretty sure I have every demo, there are like 100 of them
2011-11-04T23:49:01 < Tom_itx> stm32f4-discovery_FW_V1.0.1
2011-11-04T23:49:08 < Tom_itx> should have it
2011-11-04T23:49:27 < markamber> what is the file, do you know?
2011-11-04T23:49:37 < Tom_itx> i'm looking
2011-11-04T23:49:43 < markamber> I have that                                                         -> -^
2011-11-04T23:49:51 < markamber> thanks Tom_itx
2011-11-04T23:50:22 < markamber> Tom_itx: have you ever programmed an stm32?
2011-11-04T23:50:26 < Tom_itx> i'm not sure where they put the demo exactly but it's there
2011-11-04T23:50:30 < Tom_itx> nope
2011-11-04T23:50:35 < Tom_itx> i'm about to
2011-11-04T23:50:36 < markamber> has anyone?
2011-11-04T23:50:45 < Tom_itx> it's sitting here with st-link attached to it
2011-11-04T23:50:54 < Laurenceb_> does the stlink code have some sort of memory write prevention built in?
2011-11-04T23:51:07 < Laurenceb_> theres nothing on the usb according to wireshark
2011-11-04T23:51:19 < markamber> I just need to find some trace of documentation on how to write code for these things, there is no simple I want something to happen on a button press how to's
2011-11-04T23:51:21 < Tom_itx> i didn't wanna screw up the demo on it though without being able to save it
2011-11-04T23:51:24 < Laurenceb_> yet stlink gives an error on write attempts to SRAM
2011-11-04T23:52:09 < Tom_itx> markamber, look in the iotoggle dir
2011-11-04T23:52:17 < markamber> I just want to know how to read the state of a button (one that is not on the board) and use it in an if statement, I could also use some help with the audio playback, but the whole button thing would be a perfect start
2011-11-04T23:53:32 < markamber> if they would only put a readme in the project!
2011-11-04T23:54:08 < Tom_itx> ok, look in libraries/STM32F4xx_StdPeriph_Driver/src
2011-11-04T23:54:12 < Tom_itx> for gpio
2011-11-04T23:54:45 < markamber> so how would I hook up the button, sorry, I am just really new to this platform
2011-11-04T23:54:53 < Tom_itx> me too
2011-11-04T23:55:10 < Tom_itx> but i've been fighting linux instead of reading about the damn chip
2011-11-04T23:56:13 < Tom_itx> if you load the project in iar or something it will bring in all the sourcefiles then you can see what you've got
2011-11-04T23:56:38 < Tom_itx> then i'm gonna look for a 'main' and see what they're up to
2011-11-04T23:59:22 < Tom_itx> under Project/Demonstration may be the loaded demo
2011-11-04T23:59:22 < Laurenceb_> markamber: id be interested to know how you get on with SWD

2011-11-05T00:02:41 < Tom_itx> include the header
2011-11-05T00:03:07 < markamber> I do not want a button, I want a pull down or pull up button setup
2011-11-05T00:03:50 < Laurenceb_> so does anyone here have an F4discovery running with linux?
2011-11-05T00:03:55 < Tom_itx> set up a gpio with a button and map it with the gpio functions
2011-11-05T00:04:12 < Tom_itx> be careful, some io won't source/sink an led

2011-11-05T00:05:26 < Tom_itx> just look thru their demo a bit
2011-11-05T00:05:43 < Tom_itx> i'm sure you don't have to use their libs but they would make it simpler
2011-11-05T00:11:42 < Tom_itx> has anyone seen any other demo beside the accelerometer demo?
2011-11-05T00:14:08 < Tom_itx> i don't see where they exit that one and continue with the rest
2011-11-05T00:14:13 < Tom_itx> what triggers the accelerometer demo exit
2011-11-05T00:15:47 < Tom_itx> i don't have the micro usb plug so i can't see the whole thing

2011-11-05T00:27:02 < Tom_itx> ok, iar builds it just fine

2011-11-05T13:10:09 < Thorn> I use write_image with .elf
2011-11-05T13:11:41 < Thorn> bin does not store any information about addresses but hex does IIRC
2011-11-05T13:12:28 < Thorn> you should check the openocd guide, it's all explained there
2011-11-05T13:16:01 < grummund> i didn't see much about the difference between write_bank and write_image
2011-11-05T13:16:27 < grummund> anyway, write_image does work for me so it's kinda academic
2011-11-05T13:22:37 < grummund> ok, to answer my own question... yep, use write_bank for ihex format and write_image for bin format.

2011-11-05T14:09:51 < karlp> Laurenceb_: I was actually thinking a little earlier,
2011-11-05T14:10:05 < karlp> in the stinklybliknly package, there's a "test_usb.c" file
2011-11-05T14:10:12 < Laurenceb_> yeah i ran it
2011-11-05T14:10:18 < Laurenceb_> it seems to work 100%
2011-11-05T14:10:40 < karlp> so, you looked at the code, and let it run the pieces that you care about?
2011-11-05T14:10:53 < karlp> those are not just "make, run, it's good" pieces of code
2011-11-05T14:10:55 < Laurenceb_> i dont think it tested sram write
2011-11-05T14:11:13 < karlp> so... make it test sram write

2011-11-05T14:12:22 < Laurenceb_> oh.. does that mean ti failed?

2011-11-05T14:13:39 < karlp> those aren't really designed to have useful output,
2011-11-05T14:13:53 < karlp> they were/are tests that you need to know what they were trying to do

2011-11-05T14:14:18 < karlp> copy that section into test-usb, and see if it dumps out the memory pattern from mark_buf
2011-11-05T14:14:55 < karlp> I mean, this guy: http://cu.rious.org/make/stm32f4-discovery-board-with-linux/ has it working. at least as far as blinking, which you seem to have problems doing.

2011-11-05T16:40:52 < grummund> heh. problems like that are *so* annoying
2011-11-05T16:41:51 < Laurenceb_> ive been trying to make it work for 2 days
2011-11-05T16:42:06 < Laurenceb_> just installed summon arm-toolchain, but its unchanged
2011-11-05T16:42:07 <+Steffanx> Only 2 days?
2011-11-05T16:42:07 < grummund> what board/mcu do you have?
2011-11-05T16:42:14 < Laurenceb_> stm32F4discovery
2011-11-05T16:42:28 < Laurenceb_> using the built in SWD
2011-11-05T16:42:44 < Laurenceb_> sram should work fine
2011-11-05T16:42:52 < Laurenceb_> but i cant make it work :(
2011-11-05T16:43:06 < grummund> does it work at all in any context??
2011-11-05T16:43:14 < Laurenceb_> i can connect
2011-11-05T16:43:30 < Laurenceb_> halt, dump sram and flash, disassemble and debug with that and stuff
2011-11-05T16:43:49 < Laurenceb_> and i can write to flash, only it fails due to the wrong registers
2011-11-05T16:44:01 < Laurenceb_> thats going to be fixed soon aiui - theres a patch on the way
2011-11-05T16:44:16 < Laurenceb_> i can write to sram using st-link directly
2011-11-05T16:44:31 < Laurenceb_> just not via gdb server, i get an error back from st-link
2011-11-05T16:44:44 < Laurenceb_> i thought it was due to an older gdb version in codesourcery
2011-11-05T16:44:52 < Laurenceb_> but now ive upgraded gdb, its unchanged
2011-11-05T16:48:36 < Laurenceb_> seems from playing around with wireshark that st-link sends back an error on sram write attempt over the gdbserver

2011-11-05T17:00:26 <+Steffanx> Sure?
2011-11-05T17:01:39 < Laurenceb_> i added a handler to st-link if it doesnt know what the packet is
2011-11-05T17:03:09 < Laurenceb_> so.. gdb is sending packet header Hg0
2011-11-05T17:03:18 < Laurenceb_> which apparently other people dont see
2011-11-05T17:08:09 < grummund> Hg == mercury?
2011-11-05T17:08:12 < Laurenceb_> no
2011-11-05T17:08:24 < Laurenceb_> it means gdb thinks the target is multithreaded
2011-11-05T17:08:32 < Laurenceb_> Hg=apply g on the current thread
2011-11-05T17:08:39 < Laurenceb_> st-link doesnt support that
2011-11-05T17:09:05 < Laurenceb_> so the packet handler gives an error
2011-11-05T17:09:20 < Laurenceb_> presumably theres a config thing for gdb to turn off multithreading
2011-11-05T17:34:47 < Laurenceb_> hmm it doesnt would if i strip the H out :(
2011-11-05T17:43:18 < Laurenceb_> i added some code to strip out a leading H

2011-11-05T18:18:20 < karlp> it's nice to read back over it :)
2011-11-05T19:10:09 <@jpa-> i wonder if there would be any way to pass debug messages (printf) directly through SWD
2011-11-05T19:10:24 <@jpa-> atleast polling some memory location should work
2011-11-05T19:11:04 < karlp> there should
2011-11-05T19:11:09 < karlp> the debug trace mechanism
2011-11-05T19:11:18 < karlp> but I haven't read enough yet to know how to use it
2011-11-05T19:11:36 < karlp> also, I'm starving. what's for dinner?
2011-11-05T19:11:59 <@jpa-> thingies filled with either minced meat or mushrooms
2011-11-05T19:12:10 <@jpa-> and milk pudding for dessert
2011-11-05T19:12:16 < karlp> milk pudding?
2011-11-05T19:12:28 < karlp> thingies filled is a good idea though
2011-11-05T19:12:49 < BrainDamage> mushrooms, definetly mushrooms
2011-11-05T19:12:59 < karlp> hmm. I think mushrooms will require leaving the house

2011-11-05T19:14:42 < karlp> what's in it?
2011-11-05T19:14:47 < karlp> is it like custard?
2011-11-05T19:15:23 < BrainDamage> got chicken? perhaps curry chicken?
2011-11-05T19:15:29 <@jpa-> not like custard
2011-11-05T19:16:08 <@jpa-> milk and maize flour (and sugar)
2011-11-05T19:16:50 <@jpa-> potato flour works too
2011-11-05T20:36:28 < Laurenceb_> back
2011-11-05T20:36:34  * Laurenceb_ gave up and went out XD
2011-11-05T20:37:19 < Laurenceb_> so i added some code to strip out leading H from the packets
2011-11-05T20:37:25 < Laurenceb_> and it works and reads out the registers
2011-11-05T20:37:31 < Laurenceb_> but then fails
2011-11-05T20:38:21 < Laurenceb_> (gdb) set *(int*)0x20000000=1

2011-11-05T20:38:53 < Laurenceb_> which makes even less sense - gdb asks to read registers, registers read, gdb fails
2011-11-05T20:39:36 <+Steffanx> Still messing around Laurenceb_ ?
2011-11-05T20:40:12 < Laurenceb_> yes
2011-11-05T20:40:42 < Thorn> there's ITM_SendChar() to print via the trace facility
2011-11-05T20:41:24 <+Steffanx> You still need a client which understand it no?
2011-11-05T20:43:04 < Thorn> I think openocd does have support. another thing is whether it's going to work via jtag or not (data trace is only available via swd)
2011-11-05T20:43:46 <+Steffanx> I only use swd :)
2011-11-05T20:44:04 < Thorn> there even was an example in cmsis docs how to determine if a debugger is connected
2011-11-05T20:44:50 < Thorn> something like void HardFault_Handler() { if(debufgger) breakpoint(); else while(1);; }
2011-11-05T20:46:18 < Thorn> I'm considering a j-link clone for swd support & stable gdbserver
2011-11-05T20:52:27 < Thorn> btw I implemented no-debounce keypad scanning. it ended up having two stages of debouncing :)
2011-11-05T21:25:15 < Laurenceb_> i think something is wrong with the way gdb is behaving
2011-11-05T21:25:38 < Laurenceb_> if i load an elf that has .text starting in flash, the first packet sent by gdb is flasherase
2011-11-05T21:25:59 < Laurenceb_> but if .text is in sram, it sends register read then fails
2011-11-05T21:26:05 < Laurenceb_> surely thats not right
2011-11-05T21:28:08 < Laurenceb_> http://pastebin.com/0424ggPn
2011-11-05T21:29:55 < Thorn> line 56
2011-11-05T21:30:12 < Thorn> it receives no reply?
2011-11-05T21:30:55 < Laurenceb_> correct
2011-11-05T21:31:02 < Laurenceb_> as Hg isnt supported
2011-11-05T21:31:23 < Laurenceb_> but if i modify the packet parser so it correctly replies with the registers, it makes no difference
2011-11-05T21:32:06 < Thorn> i.e. it receives the reply and saly "Load failed"?
2011-11-05T21:32:16 < Laurenceb_> yes
2011-11-05T21:32:51 < Laurenceb_> maybe i should make it say "OK" :P
2011-11-05T21:33:12 < Thorn> time to read relevant parts of gdb and/or step them through with gdb
2011-11-05T21:33:30 < Laurenceb_> lol
2011-11-05T21:33:38 < Laurenceb_> yo dawg, i heard you like gdb
2011-11-05T21:34:09 < Laurenceb_> etc
2011-11-05T21:34:36 < Laurenceb_> im going to make stlink say 'OK'  XD

2011-11-05T22:29:24 < c0ded00d> ok cool.  I am just trying to understand the how you are using GDB with your STM board
2011-11-05T22:29:48 < c0ded00d> Connecting via RSP to OpenOCD, JTAG to dev board?
2011-11-05T22:29:56 < Xamusk> c0ded00d, my intention is to use eclipseŽs debugging, but IŽm trying variations in the command line
2011-11-05T22:30:28 < Xamusk> line: target remote localhost:3333
2011-11-05T22:30:31 < c0ded00d> OK  I saw this message where GDB was trying to send an XML file to the target with the memory map information
2011-11-05T22:30:50 < c0ded00d> actually was it the other way around?
2011-11-05T22:32:35 < Laurenceb_> karlp: i think i know whats causing my issue
2011-11-05T22:32:48 < Laurenceb_> gdb has misread/interpreted to memory map
2011-11-05T22:32:55 < Laurenceb_> it thinks sram is rom
2011-11-05T22:33:10 < Xamusk> I think I got another workaround
2011-11-05T22:33:13 < c0ded00d> thats what I thought
2011-11-05T22:33:23 < Xamusk> set remotetimeout 10000
2011-11-05T22:33:28 < Xamusk> this got me working
2011-11-05T22:33:58 < c0ded00d> What STM part are you all using?
2011-11-05T22:34:34 < Xamusk> STM32F103RET6
2011-11-05T22:39:37 < c0ded00d> In this case I would agree with Laurenceb_.  I have dealt with the RSP timeout issue in the past.  This might have to do with how long it is taking to load the target with the executable image.  Looks like it might be timing out
2011-11-05T22:48:00 < Xamusk> it is
2011-11-05T22:48:26 < Xamusk> however, I have tried that previously and it didnŽt work... must have been a combination of factors
2011-11-05T22:48:56 < Xamusk> it worked with programs up to around 40KB, but not after that

2011-11-05T23:44:28 < Thorn> why didn't ARM make accessing address 0 throw a fault? that would catch null pointers
2011-11-05T23:48:06 <@jpa-> i guess address space allocation is left to chip makers
2011-11-05T23:48:52 < Thorn> address 0 contains initial sp value and address 4 the reset handler, the cpu reads those on startup
2011-11-05T23:49:05 < Thorn> I don't think these can be changed
2011-11-05T23:50:24 < Thorn> e.g. flash in stm32 is at 0x800000 but is still mapped to 0, probably for these reasons
2011-11-05T23:51:23 < Thorn> they could shift those locations by 4 bytes and make addresses 0...3 generate a fault
2011-11-05T23:53:15 <@jpa-> or just put it at 0x10000 or something, it is not such uncommon to access foobar[i] where foobar is 0
2011-11-05T23:53:46 <@jpa-> with MPU you can probably achieve that
2011-11-05T23:53:58 < Thorn> 4Gb is a huge amount for cortex-m so why not
2011-11-05T23:54:17 < Thorn> with MMU you certainly can, not sure about MPU though

2011-11-06T00:36:11 <+Steffanx> Windows or linux is probably one of them with some small differences..

2011-11-06T00:42:10 < grummund> the link is barely visible by eye, i hope i remember it's there :P
2011-11-06T00:43:38 < Laurenceb_> holy shit
2011-11-06T00:43:40 < Laurenceb_> its working
2011-11-06T00:44:16 < grummund> success is contagious ;)
2011-11-06T00:44:17 < Laurenceb_> gdb, then halt with ctrl-c, then load, then continue
2011-11-06T00:44:53  * grummund hands Laurenceb_ a virtual beer
2011-11-06T00:45:37 < Thorn> I often see transistorts on the D+ line in dev boards. looks like they're for pulling it up with a 1.5K resistor
2011-11-06T00:45:50 < Laurenceb_> thanks XD
2011-11-06T00:45:55 < Laurenceb_> i dont know why
2011-11-06T00:46:07 < Laurenceb_> halt, kill, load, run
2011-11-06T00:46:12 < Thorn> that's what I always do when I need to debug an openocd target with gdb
2011-11-06T00:46:14 < Laurenceb_> is what i was trying before
2011-11-06T00:46:22 < Laurenceb_> guess that doesnt work with sram or something
2011-11-06T00:48:46 < Thorn> a usb example (from a lpc1768 board) http://i.imgur.com/ElLvs.jpg
2011-11-06T00:50:01 < Laurenceb_> is that for suspend or something?
2011-11-06T00:50:41 < Thorn> I wish I knew. a pullup on D+ selects usb speed iirc
2011-11-06T00:51:13 < Thorn> http://www.beyondlogic.org/usbnutshell/usb2.shtml#SpeedIdentification
2011-11-06T00:51:31 < grummund> looks like it's for connect/disconnect
2011-11-06T00:51:48 < Laurenceb_> yeah i think so
2011-11-06T00:51:52 < Laurenceb_> theres also a way to do suspend like that
2011-11-06T00:51:52 < Laurenceb_> i forget :(
2011-11-06T00:52:06 < grummund> on the Olimex it's controlled from a gpio line marked "DISC"
2011-11-06T00:52:35 <+Steffanx> Poor you
2011-11-06T00:52:36 < Thorn> so what does it do?
2011-11-06T00:52:37 < grummund> and on Thorn's circuit there's a jumper marked USB_CONNECT
2011-11-06T00:52:52 < grummund> good question
2011-11-06T00:53:13 < Thorn> a jumper and a gpio pin
2011-11-06T00:53:46 < grummund> yeah, so in effect the same... one marked "disconnect" the other "connect"
2011-11-06T00:54:07 < Thorn> all the transistor seems to do is collect a pullup (R101)
2011-11-06T00:54:13 < Thorn> *connect
2011-11-06T00:54:44 < grummund> presumably the host controller senses that
2011-11-06T00:55:48 < Thorn> yes, that's explained in the link I gave. but that's speed identification, why call it "connect"/"disconnect"
2011-11-06T00:57:38 < grummund> ah so it should only be asserted once the uC is ready to connect
2011-11-06T00:57:54 < Thorn> "For example Philips Semiconductor has a SoftConnectTM technology. When first connected to the bus, this allows the microcontroller to initialise the USB function device before it enables the pull up speed identification resistor, indicating a device is attached to the bus."
2011-11-06T00:57:59 < Thorn> that's why
2011-11-06T00:58:16 < grummund> i was paraphrasing :P
2011-11-06T00:58:31 < Thorn> so it's not just speed identification, it's a "device present" signal too
2011-11-06T00:58:57 < Thorn> yeah I found that simultaneosly :)

2011-11-06T01:00:19 < Thorn> that guide is great, I wish it explained device classes too
2011-11-06T01:00:33 < Thorn> need a book on usb
2011-11-06T01:01:49  * grummund wonders if the ST-3210B eval board has a switched pullup too...
2011-11-06T01:02:24 < grummund> since the demo firmware doesn't configure any gpio to deal with that
2011-11-06T01:02:45 < grummund> which is why i shunted the transistor
2011-11-06T01:16:29 < Thorn> these little iteadstudio boards simply have jumpers there however
2011-11-06T01:25:57 < Thorn> I fail to see any pullups in the STM-P107 board from olimex though. maybe USB OTG doesn't need them?

2011-11-06T02:04:53 < Thorn> STM3210E-EVAL does have a usb disconnect pin http://www.st.com/internet/com/TECHNICAL_RESOURCES/TECHNICAL_LITERATURE/USER_MANUAL/CD00178166.pdf page 32
2011-11-06T02:10:22 < grummund> STM3210B-EVAL has it too, either gpio controlled or forced on via a jumper
2011-11-06T02:21:04 < Thorn> Philips Semiconductor can now sue everybody for using their SoftConnect(tm) technology
2011-11-06T02:28:55 < yardleydobon> I'm getting started with an SMT32VLDiscovery in Linux. I can download Demo.bin and GPIOToggle.bin to flash, but they won't run until I unplug the board. After running stlink-download the COM LED stays lit. I've tried the reset button and the reset command. Is there something I can do to reset it without unplugging it?
2011-11-06T02:34:51 < Thorn> that probably means the chip stays in reset after programming, but I've never used discovery boards or st-link so can't help you
2011-11-06T02:51:18 < Thorn> here's a possible workaround http://marc.info/?l=linux-usb&m=121459435621262&w=2
2011-11-06T02:56:03 < yardleydobon> i just figured it out.
2011-11-06T02:56:24 < yardleydobon> i ran the status command and it said ARM status is 0x0081: halted.
2011-11-06T02:56:32 < yardleydobon> then i saw there was a run command
2011-11-06T02:56:46 < Tom_itx> in st-link there is
2011-11-06T02:56:51 < yardleydobon> i used. it started running.

2011-11-06T14:42:05 < Thorn> who said i2c was easy?
2011-11-06T14:42:13 < Thorn> on stm32, it's certainly not
2011-11-06T14:43:05 < Thorn> I barely managed to make it NAK the last received byte, and that's for 3 byte transfers. 1 and 2 byte transfers are apparently special
2011-11-06T15:13:49 < Laurenceb_> i have example code on github
2011-11-06T15:18:50 < karlp> Laurenceb_: good news! great to hear you got it working!
2011-11-06T15:19:07 < karlp> did you have to change any more code? or just the H thing for gdb?
2011-11-06T15:19:07 < Laurenceb_> yeah thanks
2011-11-06T15:19:10 < Laurenceb_> kind of working
2011-11-06T15:19:20 < Laurenceb_> the elf someone sent me works
2011-11-06T15:19:23 < karlp> do you have your changes anywhere?
2011-11-06T15:19:27 < Laurenceb_> no
2011-11-06T15:19:42 < Laurenceb_> i didnt make any changes, it only works with halt load continue
2011-11-06T15:19:51 < Laurenceb_> im not sure if thats right for sram?
2011-11-06T15:20:01  * karlp shrugs
2011-11-06T15:20:07 < Laurenceb_> previously i tried kill, but after kill you cant access ram
2011-11-06T15:20:20 < Laurenceb_> it seems to be gdb that blocks access
2011-11-06T15:20:46 < Laurenceb_> anyway, if i try loading my elf files now, it doesnt change the program counter to 0x20000000
2011-11-06T15:22:21 < Laurenceb_> hmm even with debugging off
2011-11-06T15:25:18 < Laurenceb_> the hell
2011-11-06T15:25:29 < Laurenceb_> ok it runs, but only with optimiesed code
2011-11-06T15:25:36 < Laurenceb_> *optimiesed
2011-11-06T15:25:44 < Laurenceb_> arg *optimised
2011-11-06T15:26:23 < Laurenceb_> unoptimised code with -g doesnt change the program counter
2011-11-06T15:26:38 < Laurenceb_> so it continues from flash, but usually breaks due to the corrupted sram
2011-11-06T15:27:39 < Laurenceb_> im very confused... but debugging is supposed to work with gcc with optimisation enabled?
2011-11-06T15:28:05 < Laurenceb_> at least... to an extent
2011-11-06T15:28:17 < Laurenceb_> monologue++ :P ill bbl

2011-11-06T21:04:16 < Thorn> looks like I did manage to implement polled i2c transfer for all cases (basically what the lpc17xx library provides out of the box)
2011-11-06T21:29:39 < Laurenceb_> Thorn: look for  me on github
2011-11-06T21:29:50 < Laurenceb_> i have interrupt and polled i2c
2011-11-06T21:30:11 < Thorn> yeah I've seen the i2c code in dactyl (interrupt only though)
2011-11-06T21:36:30 < Thorn> found polled version
2011-11-06T21:40:02 < Thorn> my version handles the 1 byte receive case, but no timeouts yet
2011-11-06T21:40:32 < Laurenceb_> cool
2011-11-06T21:41:25 < Thorn> I also found an stm app note on i2c implementation, and there's that CPAL library too
2011-11-06T21:41:47 < Laurenceb_> CPAL?
2011-11-06T21:41:48 < Thorn> apparently people are having problems with i2c
2011-11-06T21:41:50 < Thorn> http://www.st.com/internet/com/TECHNICAL_RESOURCES/TECHNICAL_LITERATURE/APPLICATION_NOTE/CD00209826.pdf
2011-11-06T21:41:56 < Laurenceb_> interesting
2011-11-06T21:42:03 < Thorn> cpal = "common peripheral access library" iirc
2011-11-06T21:42:08 < Laurenceb_> ok
2011-11-06T21:42:15 < Laurenceb_> from st?
2011-11-06T21:42:40 < Thorn> it's UM1029
2011-11-06T21:42:42 < Laurenceb_> yeah aiui the only outstanding problems occur if you take ages to service the isr
2011-11-06T21:42:48 < Laurenceb_> i see
2011-11-06T21:42:52 < Thorn> yes, from ST
2011-11-06T21:43:12 < Laurenceb_> there seems to have been some confusion caused by multiple datasheet revisions
2011-11-06T21:43:33 < Laurenceb_> latest datasheet pretty much describes the i2c as it functions aiui
2011-11-06T21:43:54 <+Steffanx> aiui?
2011-11-06T21:44:17 < Laurenceb_> as i understand it
2011-11-06T21:44:18 <+Steffanx> Oh nvm
2011-11-06T21:44:26 <+Steffanx> I googled it :)
2011-11-06T21:45:29 < Thorn> what datasheet are you referring to?
2011-11-06T21:45:42 < Thorn> rm0008 or actual device datasheet?
2011-11-06T21:51:01 < Thorn> btw both ICs I'm using for testing have the same slave address. thankfully they have some address select pins
2011-11-06T22:02:38 < Thorn> i2c has its own website http://www.i2c-bus.org/

2011-11-07T18:20:22 < Xamusk> hi
2011-11-07T18:20:53 < Xamusk> IŽm having a strange problem where my DMA reads (from ADC) are getting around 19% slower than it should
2011-11-07T18:21:07 < Xamusk> in a STM32F103RET6
2011-11-07T18:22:07 < Xamusk> IŽm running @72MHz, with Dual sampling of 6 ADC channels (3 DMA positions), 55.5 cycles/sample
2011-11-07T18:22:38 < Xamusk> ADC divisor is 8
2011-11-07T18:24:00 < Xamusk> by my calculations, I should get 72M/8/55.5/3 = 54K interrupt calls, but IŽm getting only 44K
2011-11-07T18:25:49 < Xamusk> any ideas?
2011-11-07T18:26:31 < grummund> Xamusk: is the system clock PLL configured correctly?
2011-11-07T18:27:05 < Xamusk> grummund, yes... I tested with something like the GPIO_Toggle example from ST, and got 18MHz on output as it should
2011-11-07T18:27:13 < grummund> ok
2011-11-07T18:27:15 -!- Tom_itx [~Tl@unaffiliated/toml/x-013812] has joined ##stm32
2011-11-07T18:27:50 < Xamusk> or at least as the example says it should... anyway, I also have a led based on SysTick, and I get what I should
2011-11-07T18:28:55 < grummund> i've not used DMA or ADC, sorry
2011-11-07T18:29:03 < Xamusk> ok
2011-11-07T18:32:41 < Xamusk> the strange part is that the relation is broken, a little less than 19%... if it was an integer relation I could have some suspects, but not for that
2011-11-07T18:33:37 < Xamusk> I set the DMA IRQ as high-priority and made it as fast as possible, with just the pin toggling
2011-11-07T18:33:43 < grummund> since it is slower than you expect could it be some samples are "missed" ?
2011-11-07T18:37:07 < Xamusk> itŽs possible, but I donŽt know whatŽs doing it
2011-11-07T18:37:14 < Xamusk> and itŽs pretty regular
2011-11-07T18:37:46 < Xamusk> if one out of two samples were missed, IŽd guess the speed would be 50% of what it should, not 81%
2011-11-07T18:39:01 < grummund> can you have tha ADC generate an interrupt on each sample?  then toggle a pin in an ISR for that.
2011-11-07T18:39:45 < Xamusk> IŽm doing that for the DMA transfer complete... IŽll try to enable that for the ADC
2011-11-07T18:40:12 < grummund> would be useful to see that they tie up
2011-11-07T18:40:38 < Xamusk> indeed
2011-11-07T18:41:11 < grummund> also to view that on a scope it should be clear if it's genuinly running slower or just skipping samples
2011-11-07T18:51:44 < Xamusk> grummund, actually, IŽm seeing most of it in the scope
2011-11-07T18:51:59 < Xamusk> which gave me the figure of 44kHz
2011-11-07T18:52:28 < Xamusk> but now I did your suggestion, and got a most interesting, if not weird, result
2011-11-07T18:54:02 < Xamusk> matching each of the DMA cycles there are two peaks for the ADC (there should be 3) and they are 840ns apart (should have been 6.16us)
2011-11-07T18:55:24 < Xamusk> IŽd expect a regular interval between the end-of-conversion
2011-11-07T19:01:45 < Xamusk> ok... got rid of the second peak... it was because the ADC1 also uses the same interrupt vector as ADC2
2011-11-07T19:02:24 < Xamusk> but IŽm still getting 44kHz
2011-11-07T19:03:02 < grummund> if it's stable at that frequency it suggests the config is wrong
2011-11-07T19:04:28 < grummund> is the ADC setup straightforwad?  i could perhaps try it here...
2011-11-07T19:14:21 <@jpa-> Xamusk: so your sample time is 55.5 cycles? isn't the total conversion time then 69.5 cycles?
2011-11-07T19:14:37 < Xamusk> 69.5?
2011-11-07T19:15:07 <@jpa-> the conversion time is 14 cycles
2011-11-07T19:16:57 <@jpa-> check 11.3.6 Timing diagram in the reference manual
2011-11-07T19:17:12 < Xamusk> damn
2011-11-07T19:17:21 < Xamusk> I totally forgot about the 12.5+ cycles
2011-11-07T19:17:30 < Xamusk> 14 cycles is for 1.5 cycle conversion
2011-11-07T19:18:13 <@jpa-> ah, yeah
2011-11-07T19:18:30 < Xamusk> jpa-, damn, you totally killed the issue!
2011-11-07T19:18:35 <@jpa-> sorry
2011-11-07T19:18:49 < Xamusk> jpa-, that was a compliment :-)
2011-11-07T19:19:15 <@jpa-> stop, stop, it's not my fault!
2011-11-07T19:19:18  * jpa- runs away
2011-11-07T19:20:44 < Xamusk> 1-55.5/(55.5+12.5)=19% !!!
2011-11-07T19:20:57 < Xamusk> just what I was looking for
2011-11-07T19:21:17 < Xamusk> damn that hidden page 216
2011-11-07T19:21:55 < Xamusk> gonna annotate the code to remember that
2011-11-07T19:22:03 < Thorn> if all else fails, rtfm.
2011-11-07T19:23:26 < Xamusk> yeah
2011-11-07T19:24:00 < Xamusk> and I did quite some reading, but somehow must have skipped that, even though I clearly remember reading that page almost 2 years ago

2011-11-07T22:23:28 < Thorn> how do I debug 2 devices at the same time? I'm implementing rs-485 and the debug adapter is already buried under one of the devices
2011-11-07T22:25:05 <+Steffanx> Ah second debugger :)
2011-11-07T22:26:43 < Thorn> that would be nice
2011-11-07T22:27:26 <+Steffanx> I once debugged something by trial and error :)
2011-11-07T22:27:34 <+Steffanx> No LED's no printf/uart :)
2011-11-07T22:27:46 <+Steffanx> It was a communication with w5100 ethernet module
2011-11-07T22:28:05 <+Steffanx> Once i got the ethernet part sort of functional i used the ethernet connection to debug itself :)
2011-11-07T22:29:44 <+Steffanx> You can debug apps pretty well with some led's and/or uart interface Thorn ..
2011-11-07T22:29:48 < Thorn> that's more or less how I started with microcontrollers (avr, no jtag, no la (but with uart available)). after implementing 1-wire in the blind it was pretty obvious I need both of those
2011-11-07T22:29:54 <+Steffanx> The fancy way
2011-11-07T22:30:43 < Thorn> I'll need to setup some kind of bootloader first though
2011-11-07T22:31:19 < Thorn> an rs-485 bootloader would be ideal but it kinda requires working rs-485 comms
2011-11-07T22:31:47 <+Steffanx> It sucks when 2 parts of a project depend on each other
2011-11-07T22:32:07 <+Steffanx> Especially when it's a wireless connection, that makes things even worse

2011-11-07T22:57:12 < quitte> hi. why are there two registers to reset GPIO bits? the second pair of bytes of BSRR and the first pair of BRR?
2011-11-07T22:57:46 <+Steffanx> To make your life easier sometimes?
2011-11-07T22:59:10 < quitte> that's very thoughtful of st. still wondering what situation that could possibly be.
2011-11-07T22:59:57 <+Steffanx> I used it a few times, not sure that situation was though
2011-11-07T23:10:03 < Thorn> BSRR is for setting bits, BRR for resetting (at least that's how the standard library appears to use them). upper half of BSRR is handy if you want to do both at the same time
2011-11-07T23:11:59 < quitte> Thorn: so it might be for historical reasons? BRR became obsolete when BSRR was extended to have reset,too?
2011-11-07T23:14:47 < Thorn> I believe STM32 peripherals were adopted from STM8, at least to some extent. but STM8 has no BRR or BSRR, only IDR and ODR

2011-11-08T00:27:53 < karlp> Laurenceb_: do you have any changes to slinkylink you could share?
2011-11-08T00:29:28 < Laurenceb_> nope
2011-11-08T00:29:33 < Laurenceb_> i fail :P
2011-11-08T00:29:41 < Laurenceb_> it was all down to how i was using gdb
2011-11-08T00:29:55 < Laurenceb_> needed to use halt, load, continue
2011-11-08T00:29:58 < Thorn> summon-arm-toolchain summons some pretty old versions
2011-11-08T00:30:01 < Laurenceb_> to run from sram
2011-11-08T00:30:32 < Thorn> such as gcc-linaro-4.5-2011.02
2011-11-08T00:31:49 < karlp> Laurenceb_: so, you run arm-none-eagbi-gdb, then what commands next?
2011-11-08T00:32:05 < karlp> I'd like to update the docs with some suggestions for people that need more than what I do
2011-11-08T00:32:39 < Laurenceb_> ctrl-c, load (elf file), continue
2011-11-08T00:32:51 < Laurenceb_> after tar ext localhost:4242
2011-11-08T00:33:15 < Laurenceb_> but if i try no optimisation, the program conter isnt reset to 0x20000000
2011-11-08T00:33:34 < Laurenceb_> although the program doesn load to sram
2011-11-08T00:33:49 < Laurenceb_>  i dont understand why the PC isnt reset correctly
2011-11-08T00:34:46 < Laurenceb_> unfortunately the nemiver gui uses halt-load-run, and so will only work with flash
2011-11-08T00:35:07 < Laurenceb_> ive got ddd working, but the motif graphics are horrible
2011-11-08T00:35:08 < karlp> yeah, that' sall I do, gdb, tar ext :4242, load elf, continue
2011-11-08T00:35:17 < Laurenceb_> cool
2011-11-08T00:35:23 < karlp> what tool were you using that was doing something else?
2011-11-08T00:35:31 < Laurenceb_> nemiver
2011-11-08T00:35:36 < karlp> I've been using gdb from the command line, to have one less thing to have to get workign :)
2011-11-08T00:35:40 < Laurenceb_> heh
2011-11-08T00:36:06 < Laurenceb_> i cant access sram after a kill in gdb
2011-11-08T00:36:14 < Laurenceb_> thats what was causing the issues
2011-11-08T00:36:47 < karlp> ahh, I've been working on restructuring and things, so my sanity tests only extended as farr as, "clean, rebuild, load into sram, see it restarted again ==> good"
2011-11-08T00:37:00 < karlp> so, on that picture you sent, what's the red line in the graph?
2011-11-08T00:37:08 < Laurenceb_> an integer
2011-11-08T00:37:23 < Laurenceb_> ddd has a view variable history tool
2011-11-08T00:37:33 < karlp> ahh, interesting.
2011-11-08T00:37:48 < Laurenceb_> rowley crossworks actually does that properly
2011-11-08T00:37:59 < karlp> so, should that line hve been linear?
2011-11-08T00:38:04 < Laurenceb_> yes
2011-11-08T00:38:22 < Laurenceb_> in rowley you can set the data record rate in Hz
2011-11-08T00:38:23 < karlp> so, is that something that slinkylink is doing badly? or what's causing that?
2011-11-08T00:38:38 < Laurenceb_> well...
2011-11-08T00:38:59 < Laurenceb_> gdb in async mode should allow reading of variables without halting
2011-11-08T00:39:08 < Laurenceb_> i didnt know that yesterday :P
2011-11-08T00:39:11 < Laurenceb_> just trying now
2011-11-08T00:40:01 < Laurenceb_> ok gdb is now behaving
2011-11-08T00:40:20 < Laurenceb_> but ddd only updates the variable on mouseover on the code viewer
2011-11-08T00:40:29 < Laurenceb_> and stlink halts the core itself
2011-11-08T00:40:46 < Laurenceb_> ill pastebin
2011-11-08T00:41:15 < karlp> if you want stlink to do something else in those things, write it all up and stick it as a ticket on texane's github.
2011-11-08T00:41:21 < karlp> I'll try and follow it there
2011-11-08T00:41:25 < Laurenceb_> http://pastebin.com/LiHxSL60
2011-11-08T00:41:35 < Laurenceb_> ^thats 1 mouseover event in ddd
2011-11-08T00:43:02 < Laurenceb_> yeah
2011-11-08T00:43:38 < Laurenceb_> looks like that core halt is done by stlink
2011-11-08T00:47:01 < karlp> which halt?
2011-11-08T00:47:50 < karlp> also, for things like the std periph driver, CMSIS core_cm3.* and so on, is there already a really nicely packaged up version that supports "lots" of the stm32 chips?
2011-11-08T00:48:10 < karlp> or does everyone build them themselves?
2011-11-08T00:48:43 < Laurenceb_> tbh ive only used the stm32f103 version so far
2011-11-08T00:49:01 < Laurenceb_> hmm interesting - looks like gdb requested the halt
2011-11-08T00:49:36 < BrainDamage> btw, can anyone give me the flash full dump please?

2011-11-08T01:40:08 < karlp> last time I looked at that project, it didn't support stlinkv2
2011-11-08T01:40:22 < karlp> heh
2011-11-08T01:42:38 < karlp> oh. no. I can't use that.
2011-11-08T01:42:53 < karlp> I've turned off usb-storage for ths stlink v1.  it's my way (libusb raw) o rthe highway
2011-11-08T01:43:32 < BrainDamage> as in, I'd have to take the highway, go physically there and modprobe sg ?
2011-11-08T01:43:44 < BrainDamage> or just swap my board with yours
2011-11-08T01:43:46 < karlp> hehe.
2011-11-08T01:43:49 < karlp> no, I'll get to thisl.
2011-11-08T01:43:59 < karlp> what I'm working on right now is being able to build the vl demo code.
2011-11-08T01:44:01 < karlp> then flash it,
2011-11-08T01:44:07 < karlp> make sure I can rebuild the working sutff
2011-11-08T01:44:09 < karlp> then I can break it.
2011-11-08T01:44:15 < karlp> see if I get the same problem as you
2011-11-08T01:44:53 < karlp> just running into compiler errors with the demo code: http://pastebin.com/iE0ZLBsB :)
2011-11-08T01:45:49 < Thorn> the mystery of the Canadian compiler is solved http://en.wikipedia.org/wiki/Cross_compiler#Canadian_Cross
2011-11-08T01:55:15 < karlp> so, anyone know why the stdperiph driver for the 32l1xx doesn't have assert_param() in it, but the VL stdperiph does?
2011-11-08T01:55:42 < karlp> hmm, no, it's in the 32l code too.
2011-11-08T01:55:47 < karlp> stupid linking
2011-11-08T01:58:19 < grummund> it's a macro
2011-11-08T02:00:19 < grummund> stm32l1xx_conf.h
2011-11-08T02:01:46 < karlp> yeah, seems the stm32f10x doesn't have that.
2011-11-08T02:01:51 < karlp> it does now :)
2011-11-08T02:02:11 < grummund> it does
2011-11-08T02:02:24 < karlp> not in the version I just downloaded :|
2011-11-08T02:02:36 < grummund> stm32f10x_conf.h
2011-11-08T02:02:51 < grummund> it should be with the project (not the library itself)
2011-11-08T02:03:01 < karlp> yeah, but in the L code, it's defined in the cmsis device support package itself
2011-11-08T02:03:20 < karlp> if I hve it in the project, I can't get it to link.
2011-11-08T02:03:44 < karlp> is SystemCoreClock also meant to be in the _conf file?
2011-11-08T02:04:50 < grummund> system_stm32f10x.[ch]
2011-11-08T02:06:51 < karlp> and those should always be per project?
2011-11-08T02:06:59 < karlp> and not in a stdperiph library?
2011-11-08T02:10:57 < grummund> i think the system_stm32f10x.c is per project because it needs to be edited for the correct clock config gto match the hardware
2011-11-08T02:12:53 < karlp> makes sense.
2011-11-08T02:16:31 < karlp> so, if assert_param is in the _conf.h file, which is included in main, shouldn't that turn ups as a symbol in main.o somewhere? so that all the library code that needs it can find it?
2011-11-08T02:16:58 < grummund> no cos it's a macro
2011-11-08T02:17:53 < karlp> so, the library files have to be _compiled_ at the same time? I can't just premake a lib_stdperiph.a then?
2011-11-08T02:18:50 < grummund> you could make a library object but it would be specific to whatever compile-time definitions you had
2011-11-08T02:19:38 < karlp> so there's really no point in even trying. and I should have a predictable directory structure, and compile the std-periph stuff each time?
2011-11-08T02:20:08 < grummund> personally i gave up on maintaining ST's directory structure
2011-11-08T02:20:09 < karlp> and not try and make some magic -lstm_stdperiph_$(PART_NAME)
2011-11-08T02:20:45 < grummund> well it needs to be done and you could lead the way :P
2011-11-08T02:20:52 < karlp> hehe
2011-11-08T02:21:21 < karlp> well, if things like assert_param won't work at all, then it doesn't sound like there's muhc point
2011-11-08T02:21:34 < karlp> I thought this was going to be relatively straightforward :)
2011-11-08T02:21:52 < grummund> you'd need separate libs for with/without assert enabled
2011-11-08T02:24:11 < karlp> ok. I'm going to make libs with NO assert right now.
2011-11-08T02:26:47 < grummund> the stdperiph code indirectly #include's stm32f10x_conf.h so technically it is a dependency
2011-11-08T02:26:56 < karlp> ok, well, that compiles and runs from sram.
2011-11-08T02:27:00 < karlp> that's kinda nice.
2011-11-08T02:27:15 < grummund> i.e. if stm32f10x_conf.h is edited then the lib.a should be rebuilt
2011-11-08T02:27:32 < grummund> even though stm32f10x_conf.h is a project file
2011-11-08T02:28:02 < karlp> do these conf files ever have any more in them than this "use full assert" stuff?
2011-11-08T02:30:31 < grummund> not much it seems
2011-11-08T02:42:10 < karlp> BrainDamage: yep, I can confirm.  I tried flashing something (which failed)
2011-11-08T02:42:22 < karlp> and now running from sram doesn't set up the stack poitner propler,y so blink doesn't work. :)
2011-11-08T02:42:37 < BrainDamage> ah thanks
2011-11-08T02:42:57 < karlp> I don't have a factory flash image for you yet,
2011-11-08T02:43:01 < karlp> but now I can work on that
2011-11-08T02:43:18 < BrainDamage> at least now I can see some light at the tunnel's end
2011-11-08T02:43:33 < BrainDamage> and I'll remember to check twice before wiping a memory sector :s
2011-11-08T02:45:07 < karlp> hmm, what's the gdb command to edit a reigster again?
2011-11-08T02:45:51 < BrainDamage> set
2011-11-08T02:46:06 < BrainDamage> set $blah=0
2011-11-08T02:49:38 < karlp> so, shouldn't p $main_sp work?
2011-11-08T02:50:09 < BrainDamage> honesntly, I did not think of that
2011-11-08T02:50:21 < BrainDamage> >_>
2011-11-08T02:50:45  * BrainDamage gets his dunce cap
2011-11-08T02:50:57 < karlp> well, I'm only trying it for the first time
2011-11-08T02:52:47 < BrainDamage> what should be the correct address for the blinky example?
2011-11-08T02:54:03 < karlp> not sure, but set $sp= blah isn't working for me anyway

2011-11-08T20:49:07 < karlp> it's a bit ugly.  openoffice's export is terrible
2011-11-08T20:55:17 < Thorn> this channel needs a wiki
2011-11-08T20:56:19 < Thorn> I can  host a dokuwiki (or a mediawiki but I hate it)
2011-11-08T20:56:29 < karlp> a wiki wouldn't be a bad idea :)
2011-11-08T20:56:46 < karlp> there's a bunch of scattered piles of information around the web, but it's horribly organised and hard to find what's current
2011-11-08T20:58:10 <+Steffanx> Wiki .. wiki's suck imho Thorn
2011-11-08T20:58:16 < Thorn> I already have a private wiki with a lot of information on cm3 and stm32, at least some parts should be useful
2011-11-08T20:58:27 < Thorn> Steffanx: what's the alternative?
2011-11-08T20:58:28 <+Steffanx> wikipedia is ok-ish, but most other wiki's suck
2011-11-08T20:58:38 <+Steffanx> A good organized wiki :P
2011-11-08T20:58:57 < karlp> which is really just basically dependent on one or two or three people actively maintaining it
2011-11-08T20:59:06 < Thorn> well, a wiki as by definition a website edited by its users
2011-11-08T20:59:14 < Thorn> *is
2011-11-08T21:00:14 < Thorn> only thing that's needed is a domain
2011-11-08T21:01:19 < karlp> I can offer beeroclock.net or ekta.is or tweak.net.au, but none of them are particularly obvious :)
2011-11-08T21:02:32 < Thorn> .co.cc names are free but they have a bad reputation
2011-11-08T21:02:38 <+Steffanx> .tk ftw!

2011-11-08T21:04:25 <+Steffanx> tk has a bad reputation too
2011-11-08T21:05:33 < BrainDamage> .info domain
2011-11-08T21:06:36 <+Steffanx> Is stm32 a trademark from st?
2011-11-08T21:06:56 < BrainDamage> very likely
2011-11-08T21:07:10 < Thorn> most likely, cortex is too
2011-11-08T21:07:15 < BrainDamage> the question is if our usage would fall under fair use policies or not
2011-11-08T21:07:46 <+Steffanx> Cortex is just an ARM tm
2011-11-08T21:08:19 <+Steffanx> http://www.st.com/internet/com/common/terms_of_use.jsp that don't list it, but that doesn't say anything
2011-11-08T21:08:49 < Thorn> arm-cortex.tk is free
2011-11-08T21:09:06 <+Steffanx> Yeah, but arm + cortex and tk ?!
2011-11-08T21:09:44 <+Steffanx> I'll pay for the .info domain if someone comes up with a good one :)
2011-11-08T21:09:48 <+Steffanx> Hosting is not my thing :)
2011-11-08T21:11:03 < Thorn> I have a linode so hosting is not a problem
2011-11-08T21:11:35 <+Steffanx> stm32wiki.info or is that too stm32 specific?
2011-11-08T21:12:04 < karlp> ok, here's the "final" version for now, with the f1x part datasheets http://palmtree.beeroclock.net/~karlp/stm32_datasheet_map.html
2011-11-08T21:12:26 <+Steffanx> Pleas write the html yourself karlp :P
2011-11-08T21:12:31 < karlp> eventually
2011-11-08T21:12:33 < karlp> I hate writing tables
2011-11-08T21:12:42 < Thorn> I wouldn't be too specific with the domain name
2011-11-08T21:12:43 <+Steffanx> That's so easy
2011-11-08T21:12:44 < karlp> especially all the column span stuff :)
2011-11-08T21:12:50 < karlp> then... there's the data :)
2011-11-08T21:12:54 < karlp> you can do it!
2011-11-08T21:12:58 < Thorn> something referring to cortex-m or cortex in general would be better imo
2011-11-08T21:13:09 <+Steffanx> cortex IS a trademark :(
2011-11-08T21:13:17 <+Steffanx> I don't want to mess with that
2011-11-08T21:14:08 <+Steffanx> Anyway, the domain doesn't really matter yet
2011-11-08T21:16:01 < Thorn> can there be problems with a community wiki that uses that trademark as a name?
2011-11-08T21:16:29 <+Steffanx> Probably..
2011-11-08T21:18:48 <+Steffanx> Anyway, your great friend left yet BrainDamage ?
2011-11-08T21:19:03 < BrainDamage> sorry?
2011-11-08T21:19:08 <+Steffanx> Berlusconi :)
2011-11-08T21:19:24 < BrainDamage> not yet, there's quite some turmoil atm
2011-11-08T21:19:30 < BrainDamage> because of the elections that'd follow
2011-11-08T21:19:43 < BrainDamage> basically, everyone wants to reform the electoral law in their advantage ..
2011-11-08T21:20:00 <+Steffanx> Hmm, ofcourse
2011-11-08T21:20:20 < BrainDamage> current law advantages berlusconi greatly
2011-11-08T21:20:31 < BrainDamage> ( he made it himself ofc )
2011-11-08T21:20:34 <+Steffanx> Why politics is such a game?! :(
2011-11-08T21:21:12 < BrainDamage> living here I long learned that politics is a drama that is only very loosely related to a state's welfare ..
2011-11-08T21:21:55 <+Steffanx> No there's something else related to a state's welfare :)
2011-11-08T21:22:15 <+Steffanx> Amount of 25-30 year old people who still live with that parents :P
2011-11-08T21:22:19 < karlp> ok. fooood then linker scripts and startup things.

2011-11-08T23:35:20 < karlp> bleh
2011-11-08T23:35:42 < karlp> I'm not sure if it's my linker scripts of if the VL flash writing code has never been right?
2011-11-08T23:35:59 < karlp> that can't be right though, can it?
2011-11-08T23:45:13 <+Steffanx> It can
2011-11-08T23:45:23 <+Steffanx> Everything is possible, until it's proven otherwise
2011-11-08T23:45:45 < karlp> hmmm.
2011-11-08T23:46:38 < karlp> I was under the impression that the write flash stuff was working, for the VL board, and I was only working with the change from scsi pass through to libusb
2011-11-08T23:46:59 < karlp> I could verify with the ram all writing,
2011-11-08T23:47:10 < karlp> but writing to flash seems to never write the first block.

2011-11-08T23:54:45 < karlp> bleh. Do I try and flash garbage onto my L board, see which one is busted?
2011-11-08T23:55:25 < karlp> has anyone got any sort of known working binary for the VL board that they can flash with any tool at all that they can vouch for?
2011-11-08T23:55:36 < karlp> then I can do one thing at a time...
2011-11-08T23:56:33 <+Steffanx> There's no binary online somewhere?
2011-11-08T23:56:50 <+Steffanx> Oh VL
2011-11-08T23:57:03 <+Steffanx> That's an st-link/v1 not?
2011-11-08T23:57:46 <+Steffanx> I have a 'some sort' of working binary
2011-11-08T23:57:51 <+Steffanx> It's only useless without additional hw
2011-11-08T23:58:15 < BrainDamage> it's a v1
2011-11-08T23:58:24 <+Steffanx> Oh, not it's not really made for the VL board, but for similar chip that's on the VL
2011-11-08T23:58:31 <+Steffanx> *no
2011-11-08T23:58:59 < BrainDamage> I was unable to flash using any tool :/
2011-11-08T23:59:14 < BrainDamage> but I can vouch that flash erase works excellent >_>

2011-11-09T15:13:17 < Laurenceb> ^the hell
2011-11-09T15:21:08 < karlp> are you experimenting with having a startup script?
2011-11-09T15:21:17 < karlp> I am too, without an awful lot of luck
2011-11-09T15:21:22 < karlp> and sorry, no idea on what you're getting
2011-11-09T15:21:54 < Laurenceb> im just trying the stlink blink demo on my stm32f103 board
2011-11-09T15:21:58 < Laurenceb> stlink connects
2011-11-09T15:22:17 < Laurenceb> but when i first started, program counter was at 0xfffffffff
2011-11-09T15:22:30 < Laurenceb> now its stuck around 0x60xxxxxx
2011-11-09T15:22:39 < Laurenceb> it seemed to flash ok
2011-11-09T15:23:01 < Laurenceb> if i power cycle its goes back to either 0xff... or 0x60...
2011-11-09T15:23:26 < Laurenceb> odd as the processor is alive according to stlink
2011-11-09T15:24:14 < karlp> as best I can tell, the examples/blink/ elfs have no way of setting up the startup stuff properly
2011-11-09T15:24:28 < karlp> and will currently never work, unless a valid app in flash sets them up properly first.
2011-11-09T15:24:42 < karlp> at least, that's my understanding based on why various things don't work when they are expected to
2011-11-09T15:25:01 < Laurenceb> ohhhhhhhh
2011-11-09T15:25:07 < Laurenceb> suddenly it makes sense
2011-11-09T15:25:16 < Laurenceb> i thought the code was _way_ too simple
2011-11-09T15:25:30 < Laurenceb> ok ill hack something together with stlib
2011-11-09T15:25:33 < karlp> however, this is why, I often said, "works for me"
2011-11-09T15:25:38 < karlp> but I was only ever running in ram
2011-11-09T15:25:42 < karlp> and had the original demo in flash
2011-11-09T15:25:50 < Laurenceb> it least my processor is alive :P
2011-11-09T15:25:51 < karlp> so I could load code into sram, and it would work
2011-11-09T15:25:55 < Laurenceb> hmm
2011-11-09T15:26:06 < Laurenceb> ill try an led flash example with stperif lib
2011-11-09T15:26:08 < karlp> now that I've flashed with some garbage,
2011-11-09T15:26:11 < karlp> it doesn't work :)
2011-11-09T15:26:13 < Laurenceb> and the proper startup code
2011-11-09T15:26:14 < karlp> at least on the VL board
2011-11-09T15:26:26 < karlp> but yeah, there needs to be proper startup code somewhere
2011-11-09T15:26:34 < karlp> that's what I'm working on my "libwork" branch on github
2011-11-09T15:43:29 <@jpa-> Laurenceb: that is a crappy start address

2011-11-09T17:32:24 < karlp> Laurenceb: with that pastbin code, where is SystemInit? that's not your dactyl code is it?
2011-11-09T17:33:42 < karlp> which of the code in your github dactyl repo was used to build that?
2011-11-09T18:05:35 < Laurenceb> somewhere in the lib
2011-11-09T18:05:52 < Laurenceb> its been a while sorry - use grep
2011-11-09T18:48:41 < karlp> but, didn't you say you only just got it working today? you didn't have to change anything to make it work this afternoon?
2011-11-09T19:16:50 < Laurenceb> that was another board
2011-11-09T19:17:03 < Laurenceb> i was trying the example code from texane before
2011-11-09T19:25:26 < karlp> so, it was the dactyl code, as it is on github, that you got running on your own board, with stlink v2 hardware, and my version of the stlink software?

2011-11-09T20:38:39 <+Steffanx> karlp's version of what?
2011-11-09T20:39:25 <@jpa-> stlink
2011-11-09T20:39:44 <@jpa-> with stm32f105, with which the texane stlink wouldn't write to flash
2011-11-09T20:39:44 <+Steffanx> tool
2011-11-09T20:43:52 <@jpa-> ah well, can't actually execute it but atleast it wrote something :)
2011-11-09T20:44:09 <+Steffanx> I give you another try jpa-
2011-11-09T20:44:12 <+Steffanx> karlp's version of what?
2011-11-09T20:45:01 <@jpa-> your butt
2011-11-09T20:45:08 <+Steffanx> No
2011-11-09T20:45:24 <+Steffanx> You have to say "the st-link tool"
2011-11-09T20:45:26 <+Steffanx> So:
2011-11-09T20:45:28 <+Steffanx> karlp's version of what?
2011-11-09T20:48:12 <@jpa-> oh crap, kernel panic again :(
2011-11-09T20:48:35 <+Steffanx> I think the st-link tool did that
2011-11-09T20:50:30 <+Steffanx> I think it's a punishment  jpa-
2011-11-09T20:51:04 <@jpa-> yes it did
2011-11-09T20:51:32 <@jpa-> but remember who has the ops; in *my* channel we talk about "stlink" ,)
2011-11-09T20:51:36 <+Steffanx> You refused to say "st-link tool" so you got punished
2011-11-09T20:51:55 <+Steffanx> stlink = the programmer :)
2011-11-09T20:52:45 < BrainDamage> should I get popcorn?
2011-11-09T20:53:05 <+Steffanx> You want popcorn?
2011-11-09T20:53:36 < BrainDamage> it's a non-optional social convention when enjoying a show
2011-11-09T20:53:55 < BrainDamage> so it's not if I want, I have to
2011-11-09T21:08:09 <@jpa-> karlp: hmm, any idea why my gdb doesn't get the register values right from your st-util? in the st-util debug output the registers are correct, but in gdb e.g. p $r0 gives garbage
2011-11-09T21:12:01 < karlp> no idea?
2011-11-09T21:12:15 < karlp> laurencb might know, he has been looking at the gdb interface
2011-11-09T21:12:28 < karlp> that stuff was done by some other guy, I've never looked at gdb remote much ...
2011-11-09T21:13:59 <@jpa-> well, do you know if the current version on github works for somebody?
2011-11-09T21:14:51 < karlp> I can do register reads ok on mine
2011-11-09T21:14:54 < karlp> I'm working on flashing
2011-11-09T21:15:21 < karlp> tonight I was going to try and use the stlinkv2 to reprogram my VL board using the SWD from the stlinkv2 on the 32L board.
2011-11-09T21:15:45 < karlp> but I'm about to have dinner, and have guests over, so I'm not sure if it will get there tonight...
2011-11-09T21:16:02 < karlp> well, laurenceb said it was working for him finally this afternoon right?
2011-11-09T21:28:49 <@jpa-> i'm not sure what he got working, but his problems seemed similar to what i have now (pc reading totally wrong)
2011-11-09T21:40:29 <+Steffanx> +1 for jpa- :)
2011-11-09T21:40:59 <@jpa-> for what? for calling it "stlink"? :)
2011-11-09T21:41:38 <+Steffanx> No you didn't that's why
2011-11-09T21:42:28 < BrainDamage> call it "stink"
2011-11-09T21:42:43 <+Steffanx> st-util :)
2011-11-09T21:45:02 < karlp> st-util is the name of the binary, I've been leaning towards slinky or slinkylink
2011-11-09T21:45:32 < BrainDamage> can you rename the flash tool btw?
2011-11-09T21:45:42 < BrainDamage> here I rename it to st-flash because atm it's too generic
2011-11-09T21:45:43 < karlp> I'm in the process of rmeoving it completely,
2011-11-09T21:45:55 < karlp> but I need to make sure things work, before I just change names :)

2011-11-09T22:33:41 < karlp> jpa-: so you're seeing the right values in the debug output from st-utils, but "p $r1" doesn't work in arm-none-eabi-gdb after tar ext :4242 ?

2011-11-09T23:00:20 < Thorn> btw, i2c only works if I2C_DeInit() is called before initialization. I wonder if it's documented anywhere
2011-11-09T23:02:55 < Laurenceb_> heh
2011-11-09T23:03:05 < Laurenceb_> i think theres some sort of internal state machine
2011-11-09T23:03:39 < Thorn> otherwise there's a single pulse on both SDA and SCK simultaneously that doesn't look lile a start or anything and that's it
2011-11-09T23:04:39 < Thorn> code hangs waiting for I2C_EVENT_MASTER_MODE_SELECT
2011-11-09T23:04:56 <+Steffanx> Time to stop using that stm32 peripheral lib Thorn ?
2011-11-09T23:06:37 < Thorn> it doesn't appear to do anything wrong, I read the manual and looked through the library code
2011-11-09T23:07:29  * Laurenceb_ checks his code
2011-11-09T23:08:28 < Laurenceb_> https://github.com/Laurenceb/Dactyl/blob/master/Archived/i2c.c
2011-11-09T23:09:00 < Laurenceb_> I2C_GenerateSTART( I2C1, ENABLE );

2011-11-09T23:09:28 < Laurenceb_> i dont deinit
2011-11-09T23:09:34 < Laurenceb_> but that works for me
2011-11-09T23:09:48 < Thorn> that's pretty much exactly what I have, including initialization. but it doesn't work for me without deinit
2011-11-09T23:10:38 < Laurenceb_> which processor?
2011-11-09T23:11:21 < Thorn> this is my code (timeouts not yet implemented) http://pastebin.com/GTEqph0T
2011-11-09T23:11:28 < Thorn> f103vc
2011-11-09T23:11:45 < Laurenceb_> hmm
2011-11-09T23:11:50 < Laurenceb_> im using 103 too
2011-11-09T23:11:57 < Laurenceb_> you remeber to clk it?
2011-11-09T23:12:21 < Laurenceb_> yeah
2011-11-09T23:13:03 < Thorn> it does work with the deinit
2011-11-09T23:13:35 < Laurenceb_> hangs at line 83?
2011-11-09T23:13:43 < Thorn> indents are broken in pastebin as usual
2011-11-09T23:13:48 < Laurenceb_> heh
2011-11-09T23:13:52 < Thorn> that's right
2011-11-09T23:14:34 < Laurenceb_> how odd
2011-11-09T23:14:48 < Laurenceb_> I2C_StructInit(&I2C_InitStructure); <- i never use that
2011-11-09T23:15:27 < Thorn> that doesn't seem to have any effect
2011-11-09T23:15:36 < Laurenceb_> also i init then enable
2011-11-09T23:15:54 < Laurenceb_> you do it the other way around
2011-11-09T23:16:13 < Thorn> hmm that's probably an error, testing
2011-11-09T23:16:17 < Laurenceb_> loading registers one at a time whilst its running might screw it
2011-11-09T23:17:18 < Thorn> exchanged init with enable, commented out deinit, blank LCD again
2011-11-09T23:17:55 < Laurenceb_> odd
2011-11-09T23:18:07 < Laurenceb_> maybe its different stm32 revisions
2011-11-09T23:18:09 < Thorn> uncommented deinit, lcd displays stuff
2011-11-09T23:18:30 < Laurenceb_> does it work once after power on?
2011-11-09T23:18:34 < Thorn> I found that deinit hint on a forum, it wasn't explained in any way
2011-11-09T23:18:45 < Laurenceb_> then fails on reset?
2011-11-09T23:19:04 < Thorn> nope
2011-11-09T23:19:13 < Laurenceb_> ok thats just weird
2011-11-09T23:19:20 < Laurenceb_> maybe my processor is newer
2011-11-09T23:19:24 < Thorn> completely agree
2011-11-09T23:19:40 < Laurenceb_> as it should be deinit on power on reset
2011-11-09T23:20:10 < Laurenceb_> maybe you could test my interrupt driven code?
2011-11-09T23:20:29 < Thorn> deinit "resets i2c controller registers to their power-on values" as documented
2011-11-09T23:20:30 < Laurenceb_>  #openpilot couldnt get interrupt driven i2c working properly
2011-11-09T23:20:34 < Laurenceb_> lol
2011-11-09T23:20:41 < Laurenceb_> but i managed ok...
2011-11-09T23:21:05 < Laurenceb_> im wondering if my stm32f103 from farnell are newer revisions or something
2011-11-09T23:21:14 < Laurenceb_> as i havent had any issues with i2c XD
2011-11-09T23:21:39 < Thorn> you can query chip revision, I wrote some code for that
2011-11-09T23:22:09 < Laurenceb_> i dont have my hardware setup
2011-11-09T23:22:45 < Thorn> http://pastebin.com/Xbt6iWGT
2011-11-09T23:23:48 < Thorn> there aren't many revisions at all (although need to recheck the table in rm0008 rev. 14, I think something was changed there)
2011-11-09T23:24:29 < karlp> chip revision is even in the chip decode...
2011-11-09T23:24:49 < karlp> it should be in slinkylink's debug output somewhere
2011-11-09T23:24:54 < Laurenceb_> it is
2011-11-09T23:25:04 < Laurenceb_> but i dont have it setup - its at work
2011-11-09T23:25:39 < karlp> so, blinkyII, that jpa linked to, writes flash ok via SWD from a stlink2 device,
2011-11-09T23:25:50 < karlp> but it doesn't actually blink anything :|
2011-11-09T23:26:02 < Laurenceb_> im guessing a hardware fault corrupts the registers at power on
2011-11-09T23:26:16 < karlp> I'm over it for tonight, it's been the last two nights fully solid.
2011-11-09T23:26:18 < Laurenceb_> wheres the code?
2011-11-09T23:26:28 < Thorn> I'll try interrupt driven i2c as soon as I get around to it
2011-11-09T23:27:20 < Laurenceb_> you can set priorities for the different i2c 'jobs' and completion tasks
2011-11-09T23:27:30  * Laurenceb_ is very proud of his i2c interrupt code :P
2011-11-09T23:28:23 < Laurenceb_> e.g. EXTI ISR from a data ready pin requests a task, and the task completion task sets a thread running to process the data
2011-11-09T23:28:35 < Thorn> I looked at it a couple days ago, it seems quite useful
2011-11-09T23:28:46 < Laurenceb_> it makes i2c practical even tho its so slow
2011-11-09T23:29:48 < Thorn> I'll probably use freertos tasks & queues though :)
2011-11-09T23:30:10 < Thorn> even though I don't particularly love freertos
2011-11-09T23:31:48 < Thorn> but the usage of tasks that receive information from ISRs via queues makes code sequential
2011-11-09T23:32:51 < Thorn> as opposed to lots of callbacks (a classical problem in asyncronous code)
2011-11-09T23:33:54 < Laurenceb_> yeah
2011-11-09T23:34:06 < Laurenceb_> im actually using a software generated interrupt
2011-11-09T23:34:15 < Laurenceb_> and group priorities
2011-11-09T23:34:26 < Laurenceb_> to get a form of multitasking
2011-11-09T23:37:18 < Thorn> I haven't yet found any books or other sources that deal with using interrupt priorities in detail
2011-11-09T23:37:34 < Thorn> although the topic seems quite important
2011-11-09T23:39:39 < Laurenceb_> yeah took me a while to figure out
2011-11-09T23:40:01 < Laurenceb_> found some comments in the st perif lib code, and some ref manuals on the arm site
2011-11-09T23:40:24 < Laurenceb_> look at my interrupts.c
2011-11-09T23:43:26 < Thorn> setting them up is not as much a problem as actually using them (figuring out which priorities to assign, etc)
2011-11-09T23:46:22 < Thorn> one problem in freertos is you can't use short-running tasks that are only started when needed, I believe that's basically what you implemented
2011-11-09T23:50:25 < Thorn> btw, a similar design is described in some detail here http://www.amazon.com/Apollo-Guidance-Computer-Architecture-Exploration/dp/1441908765/

2011-11-10T00:43:49 <+Steffanx> The code is
2011-11-10T00:43:56 < Laurenceb_> and anyone can write cleaner code than the firmware for that thing O_o
2011-11-10T00:44:05 <+Steffanx> :D
2011-11-10T00:44:23 <+Steffanx> Yeah, sometimes I REALLY surprised how things can work in this world
2011-11-10T00:45:01 <+Steffanx> Some companies could be so much for effective with some skilled programers
2011-11-10T00:45:03 <+Steffanx> *programmers
2011-11-10T00:45:43 < Laurenceb_> its mostly loads of 32bit hex values for different registers and their contents
2011-11-10T00:46:03 < Laurenceb_> then someone went through all the source pressing tab randomly
2011-11-10T00:46:48 <+Steffanx> stack overflow? :)
2011-11-10T00:46:50 < Laurenceb_> and theres some funny functions like an auto-destruct
2011-11-10T00:47:05 < Laurenceb_> that fries loads of the electronics if you dont have a valid license
2011-11-10T00:47:12 <+Steffanx> wtf
2011-11-10T00:47:48 < Laurenceb_> if you dont update your license and try to download...
2011-11-10T00:47:58 <+Steffanx> That sucks
2011-11-10T00:48:13 <+Steffanx> Why?!

2011-11-10T00:49:53 <+Steffanx> Why they can't just erase the cpu?
2011-11-10T00:50:10 < Laurenceb_> cuz it might be possible to ressurect
2011-11-10T00:50:19 < Laurenceb_> e.g. jtag port on the side
2011-11-10T00:50:27 <+Steffanx> True, but how many really do that?
2011-11-10T00:50:45 < Laurenceb_> i tihkn they went a little excessive XD
2011-11-10T00:50:48 <+Steffanx> Next time when someone buys it they will bypass everything
2011-11-10T00:51:09 <+Steffanx> And makes the self-destruct less effective or even in-effective :)
2011-11-10T00:51:41 <+Steffanx> Shouldn't be that hard to reverse engineer that part
2011-11-10T00:51:45 < Laurenceb_> thats one place where stm32 could be improved
2011-11-10T00:51:54 < Laurenceb_> if it have v_core input
2011-11-10T00:51:58 < Laurenceb_> *had
2011-11-10T00:52:09 < Laurenceb_> then you could use a switching regulator

2011-11-11T07:59:19 <@jpa-> karlp: this https://github.com/karlp/stlink/pull/1
2011-11-11T08:18:49 < ziph> Have I got it right that all one has to do on an M3 to have an interrupt preempt another is to raise it to a higher priority group?
2011-11-11T08:46:02 < erik-k> I seem to have a rather, eh, crippling problem... all the float-input routines (*scanf, atod/atof, strtod, ...) fail to compile with some bs library error:
2011-11-11T08:46:13 < erik-k> /home/erik-k/stm_development/lib/gcc/arm-none-eabi/4.4.5/../../../../arm-none-eabi/lib/thumb/libg.a(lib_a-syscalls.o): In function `_sbrk':
2011-11-11T08:46:15 < erik-k> syscalls.c:(.text._sbrk+0x30): undefined reference to `end'
2011-11-11T08:50:46 <@jpa-> erik-k: have you implemented _sbrk, malloc?
2011-11-11T08:51:07 < erik-k> ... no.
2011-11-11T08:51:14 <@jpa-> you need to :)
2011-11-11T08:51:21 <@jpa-> _sbrk is what gives them memory :)
2011-11-11T08:51:44 <@jpa-> unless your malloc() magically works without it
2011-11-11T08:51:50 < erik-k> http://files.sharenator.com/fuuuuuuuuuuuuuuuuu2_RE_David_Cameron-s386x294-59750.jpg
2011-11-11T08:52:24 < erik-k> And when did a dumb atof start requiring memory allocation?
2011-11-11T09:06:24  * erik-k sighs and outlines an atof that doesn't require memory allocation
2011-11-11T09:29:11 <@jpa-> the newlib atof implementation uses bigints for parsing
2011-11-11T09:32:58 < erik-k> Why? float will just overflow on anything > 1e37 and double on anything > 1e303 and long double on anything > 1e2000 anyway
2011-11-11T09:40:16 <@jpa-> don't ask me - maybe it has something to do with rounding or numeric stability or something
2011-11-11T09:41:43 <@jpa-> there is no big enough integer type to hold it, and adding small increments to floats causes problems (like if you take in every number, multiply float x by 10, add number to x)
2011-11-11T09:42:28 <@jpa-> you'll get an answer that is close but not exactly correct :)
2011-11-11T11:31:45 < karlp> jpa-: fix looks good! sorry, I was a bit burnt out last night, feeling a bit fresher today :) will try and get that pulled in later today or tonight.  I suspect that's been broken since the stlinkv2 support got merged in.
2011-11-11T11:31:57  * karlp really needs to work out some way of automatically testing some of this stuff
2011-11-11T12:10:24 < ziph> karlp: Floating point arithmetic?
2011-11-11T12:11:07 < karlp> no sorry, st-link software stuff
2011-11-11T12:14:16 < ziph> Oh, no idea then, I actually use NXP's. ;)
2011-11-11T12:14:47 < karlp> well, in theory, you'll be able to use an STM discovery board with the SWD headers to program and debug your NXP too :)
2011-11-11T12:14:53 < karlp> though I haven't tried it of course :)
2011-11-11T12:15:07 < karlp> and it's certainly not the focus, and I can basically guarantee that it won't work yet :)
2011-11-11T12:15:33 < ziph> I'm sure that would violate the licence terms STM uses. ;)
2011-11-11T12:15:45 < karlp> probably :)
2011-11-11T12:16:00 < karlp> the discovery boards aren't meant to be used for anything real.
2011-11-11T12:16:35 < karlp> anyway, I'm going to try and work hard this morning, finish my projects, and then sneak off and do stlink stuff this afternoon

2011-11-11T16:17:14 < Laurenceb> ok wtf
2011-11-11T16:17:33 < Laurenceb> my stm32 never responds to the 0x00 command
2011-11-11T16:17:41 < Laurenceb> in usart1 bootloade rmode
2011-11-11T16:26:23 < Laurenceb> maybe its rfi
2011-11-11T16:28:56 < Laurenceb> the stm32 sends out the ack packet
2011-11-11T16:29:03 < Laurenceb> then no longer responds
2011-11-11T16:33:45 < Laurenceb> lowering tx power doesnt help :-/
2011-11-11T16:34:03 < ziph> tx power?
2011-11-11T16:35:35 < Laurenceb> of my bluetooth module
2011-11-11T16:35:46 < Laurenceb> im wondering if its maybe version of  the stm32
2011-11-11T16:35:53 < Laurenceb> and the bllotloader has changed
2011-11-11T16:36:12 < ziph> Maybe.
2011-11-11T16:36:14 < Laurenceb> as if i skip to eraseflash i get a NACK
2011-11-11T16:36:46 < ziph> I wasted a bunch of time recently on a codec that had two models that were supposedly functionally exactly the same but had different default register values. :)
2011-11-11T16:38:38 < Tom_itx> documented?
2011-11-11T16:41:28 < Laurenceb> oh
2011-11-11T16:41:35 < Laurenceb> i think parity might not be working
2011-11-11T16:41:42 < Laurenceb> need to check some more
2011-11-11T16:41:54 < Laurenceb> oh
2011-11-11T16:42:06 < Laurenceb> yeah i need to enable it on my bluetooth config
2011-11-11T16:56:02 < Laurenceb> hell yeah
2011-11-11T16:56:03 < Laurenceb> works
2011-11-11T17:05:04 < karlp> bootloading over serial on bluetooth?
2011-11-11T17:06:36 < Laurenceb> yes
2011-11-11T17:07:11 < Laurenceb> i can just run make upload and it runs
2011-11-11T17:10:19 < Laurenceb> how does the stm32 chip id work?
2011-11-11T17:10:38 < Laurenceb> 0x04 0x10 is my chip id
2011-11-11T17:11:38 < karlp> it's on a specific page of the RM0008 or something
2011-11-11T17:11:46 < karlp> I can't remember off the top of my head.
2011-11-11T17:12:09 < karlp> you can look near the top of gdbserver.c and also in st-common.c
2011-11-11T17:13:05 < Laurenceb> ill search in the manual
2011-11-11T17:18:43 < Laurenceb> hmm ref manual doesnt say how its encoded
2011-11-11T17:18:57 < Laurenceb> apparently you can work out data of manufacture and stuff from it
2011-11-11T17:19:22 < Laurenceb> date of manufacture, silicon revision, batch number, wafer position x,y, iirc
2011-11-11T17:19:54 < karlp> hmm, I haven't read that, but the RM does talk about reserved bits
2011-11-11T17:21:08 < Laurenceb> theres got to be interesting things they could do
2011-11-11T17:21:19 < Laurenceb> identification of couterfits
2011-11-11T17:21:24 < Laurenceb> and stuff like that
2011-11-11T17:33:23 < karlp> so, I did a git pull, and because i had local changes, it's made it a merge, rather than just including the upstream changes and mine on top,
2011-11-11T17:33:31 < karlp> what I wanted was probably to rebase mine on top?
2011-11-11T17:33:35  * karlp wonders how to fix it now.
2011-11-11T17:33:42 < Laurenceb> i think you can force
2011-11-11T17:35:39  * karlp curses
2011-11-11T17:35:44 < karlp> now it's just thrown away my change
2011-11-11T17:35:49 < karlp> sometimes I love it so much
2011-11-11T17:35:57 < karlp> sometimes it just makes such a mess
2011-11-11T17:36:01 < BrainDamage> karlp: yes, you should've rebased
2011-11-11T17:36:23 < karlp> I wanted to get one commit entry from jpa, not his, a merge of shis into mine, and another merge of my github into my local
2011-11-11T17:39:27 <@jpa-> haha :)

2011-11-11T17:40:44 < BrainDamage> I wish :p
2011-11-11T17:41:26 < karlp> jpa-: not sure, I probably could have added your github as a remote locally, cherry picked the single commit into my master, and then repushed to github,
2011-11-11T17:41:36 < karlp> but not sure how that would have show up in githubs network and pull requests
2011-11-11T17:41:38 < BrainDamage> karlp: sfw, and git related https://imgur.com/RelqV
2011-11-11T17:41:42 < karlp> anyway, not it looks ok.
2011-11-11T17:42:09 <@jpa-> karlp: hmm, why not just accept the pull request and then pull from your repo?
2011-11-11T17:42:15 < karlp> I did.
2011-11-11T17:42:25 < karlp> but I had another commit ahead on my local master
2011-11-11T17:42:49 <@jpa-> and it merges them.. shouldn't merge mean that it keeps edits from both branches
2011-11-11T17:42:52 < karlp> doing accept pull, then pull from github to my local gave me yoru commit, a merge of your branch into my github master, and _another_ merge of github into local
2011-11-11T17:43:18 < karlp> then I tried some reset --hard trickery, and rboke it
2011-11-11T17:43:23 < karlp> never mind, it's all ok now.
2011-11-11T17:43:38 < karlp> BrainDamage: that's a nice graph :)
2011-11-11T17:43:43 < karlp> I'll keep that
2011-11-11T17:44:22 < BrainDamage> I like the lynch mob part
2011-11-11T17:44:44 < karlp> yeah :)
2011-11-11T17:44:54 < karlp> ok, must finish what I started, it's 3:44!

2011-11-11T22:59:07 < karlp> so, eabi means I should be able to build an elf on linux, and program it from windows right?
2011-11-11T23:20:23 <@jpa-> umm, yeah, but that has nothing to do with eabi
2011-11-11T23:30:51 < karlp> I thought it was eabi that said that objects from different tools should be interchangeable
2011-11-11T23:30:58 < karlp> I guess by the time it's an elf, that' sover?
2011-11-11T23:35:23 <@jpa-> elf is just a container
2011-11-11T23:35:40 <@jpa-> but if you are just writing flash, there is nothing about interoperability about code
2011-11-11T23:35:58 <@jpa-> eabi would matter if you were compiling half of the program with IAR and another half with GCC
2011-11-11T23:39:48 < Thorn> karlp: you're cross-compiling. it doesn't matter at all what your host system is as long as your compiler runs on it at all
2011-11-11T23:40:25 < karlp> I was mor ecurious about elf, I know that ihex or srec, once built can be copied at will on other machines,
2011-11-11T23:40:41 < karlp> I was more curious if arm-xxx-objcopy would work equally well on any system
2011-11-11T23:40:51 < Thorn> I don't see why not
2011-11-11T23:41:02 < karlp> I didn't think so, but I've had my sanity tested a bit recently :)
2011-11-11T23:44:23 < Thorn> well you can take e.g. a linux binary and copy it to a windows system, you can't run it there but it's not going to get mangled or anything. it's just a binary file
--- Day changed Sat Nov 12 2011
2011-11-12T00:02:53 < karlp> hmm. interesting.  the blinkyii samples that jpa pointed me to, and my own compilations of the factory demo code don't make the lightts blink even when programming with the windows st link utility
2011-11-12T00:03:15 < karlp> next up, the libopencm3 demos and atollic when it finishes downloading...
2011-11-12T00:04:16 <@jpa-> which board are you using
2011-11-12T00:08:56 < karlp> this is on the VL board

2011-11-12T00:09:14 < karlp> even though that's personally more interesting
2011-11-12T00:10:52 < karlp> hmm, the stlink utility read the binary back out, and it's identical to the readout done via the slinkylinky software

2011-11-12T01:13:52 < karlp> whee, even better, now I have a binary that I actually _compiled_ on linux, that flashes with stlink's windows utility
2011-11-12T01:14:12 < karlp> _now_ I can get back to flashing with slinkylink
2011-11-12T01:14:47 < karlp> finally.
2011-11-12T01:16:48 < BrainDamage> perhaps sniff the traffic while flashing?

2011-11-12T01:17:41 < BrainDamage> did you change anything, or the original worked?

2011-11-12T01:21:32 < karlp> run_flash_loader(0x8000000) == -1
2011-11-12T01:21:49 < karlp> it's worked occasionally, but I haven't worked out what's not getting reset properly
2011-11-12T01:22:34 <@jpa-> for me it works quite reliably, albeit a bit slowly
2011-11-12T01:22:47 < karlp> yeah, it only does 40 word pages
2011-11-12T01:22:56 < karlp> the write buffer should probably be expanded substantially.
2011-11-12T01:24:07 < karlp> ahh, I think I know  what it is.
2011-11-12T01:24:29 < karlp> my local master probably includes some of the untested chagnes from texane I picked up without fully looking over
2011-11-12T01:25:30 < karlp> yep
2011-11-12T01:25:32 < karlp> fixed
2011-11-12T01:25:40 < karlp> ok, excellent.
2011-11-12T01:25:47 < karlp> now I know what bits need to be reviewed/thrown out
2011-11-12T01:25:59 < karlp> the recent top of tree from texane breaks 32VL support.
2011-11-12T01:26:35 < karlp> ok. beer time, I'll look at that later.  thanks for those _very_ useful datapoints jpa :)
2011-11-12T01:26:51 <@jpa-> :)
2011-11-12T01:27:22 < karlp> schweet
2011-11-12T01:28:37 < karlp> yeah, via stlink2 and stlink1
2011-11-12T01:29:02 < karlp> note to self. do NOT push my local master anywhere!

2011-11-12T07:39:24 < erik-k> My stm32h107 board seems to consume an anomalously large current (220mA) compared to the statements in the device datasheet (ca 70mA running full-bore)... Does this input current indicate something is seriously wrong?
2011-11-12T07:39:55 < erik-k> There are a few other things attached (max232, LEDs on devboard) but their consumption is small

2011-11-12T11:46:49 <@jpa-> erik-k: what if you hold the reset button down? how much is the current?
2011-11-12T11:47:42 < erik-k> jpa-: It's currently sitting in a lab several miles away...
2011-11-12T11:48:09 < erik-k> I've seen the current pop up a few mA when I connect rs232
2011-11-12T11:49:06 <@jpa-> i'm just thinking along the lines that the reset will force all pins to high-z and stop the processor, so if there is still high current then it is physical short-circuit
2011-11-12T11:49:20 <@jpa-> otherwise you are just driving current into USB_FAULT probably ,)
2011-11-12T11:53:18  * erik-k looks into USB_FAULT
2011-11-12T11:54:56 <@jpa-> though i don't know why that would be active
2011-11-12T11:55:06 <@jpa-> not much other conflicts you could make on that board
2011-11-12T11:57:56 < erik-k> Nothing happens on usb_fault if I've configured PE15 as GPIO output though, right?
2011-11-12T11:59:33 < erik-k> unless... oh shit, that usb power chip...
2011-11-12T12:00:02 < erik-k> -_-
2011-11-12T12:02:25 < erik-k> This is a problem because my external 5V regulator [because I need access to the "HV" supply for other power which the breakout board doesn't give] is an soic8 that handles 200mA poorly when there's more than a fraction of a volt across it for obvious reasons
2011-11-12T12:06:17 < Thorn> what's that st205 anyway and what for? I've only seen those in olimiex boards
2011-11-12T12:06:25  * erik-k notes this means moving functionality elsewhere... probably from E12-15 to E0-3
2011-11-12T12:11:07 <@jpa-> it should be inactive though unless you are drawing overcurrent from usb

2011-11-13T01:30:50 < Tom_itx> what have you done so far?
2011-11-13T01:31:11 <+Steffanx> Actually i didn't do much at all
2011-11-13T01:31:22 <@jpa-> i've done just homework
2011-11-13T01:31:30 <@jpa-> and broke one pressure sensor
2011-11-13T01:31:31 <+Steffanx> Homework.. i don't have that anymore
2011-11-13T01:31:46 < Tom_itx> i have lots of home work
2011-11-13T01:31:53 < Tom_itx> not the kind you're thinking of though
2011-11-13T01:31:55 <+Steffanx> I only did a small design on my clone of Tom_itx toaster oven
2011-11-13T01:32:15 <+Steffanx> And I read something about how to work with triacs etc. .. i've never done that
2011-11-13T01:32:21 < Tom_itx> Steffanx, figure easy to use plugs for it too
2011-11-13T01:32:33 <+Steffanx> plugs?
2011-11-13T01:32:35 < Tom_itx> i think you need to use your arm to control the oven
2011-11-13T01:32:51 <+Steffanx> plugs?
2011-11-13T01:32:53 < Tom_itx> may be pushing it's ability
2011-11-13T01:32:58 <@jpa-> i've done it once, but triacs had not prepared themselves to work with me
2011-11-13T01:33:10 < Tom_itx> i put plugs on mine for the serial lcd, the triac board etc
2011-11-13T01:33:33 <+Steffanx> Oh, i'll do that, but that'll be separate boards
2011-11-13T01:34:00 < Tom_itx> are you doing a serial board for the lcd too?
2011-11-13T01:34:09 <+Steffanx> Not sure yet
2011-11-13T01:34:17 < Tom_itx> holler if you want it
2011-11-13T01:34:56 <+Steffanx> Nah, I like to do things myself/my way
2011-11-13T01:37:31 < Tom_itx> it's a backplane design, plug it right in the back of either a 2x8 or 1x16
2011-11-13T01:38:12 < Tom_itx> http://tom-itx.dyndns.org:81/~webpage/toaster_oven/serial_lcd_brd.png
2011-11-13T01:38:20 <+Steffanx> For hobby projects i try to design most of it myself.. especially the software
2011-11-13T01:41:43 <@jpa-> reinventing lcd control is not worth it :)
2011-11-13T01:41:54 <+Steffanx> It is :0

2011-11-13T13:54:20 <@jpa-> BadDwarf: i'm not sure if you can combine them or not, but you could just store the previous capture value and subtract it from the next one
2011-11-13T13:54:38 <@jpa-> if you do the subtraction using uint16_t, it will also work correctly in wraparound cases

2011-11-13T16:00:45 < jpa-> noooooooooooo
2011-11-13T16:00:47 < jpa-> my ops!
2011-11-13T16:09:46 < BadDwarf> jpa-: aye.. I could do the subtraction.. trying everything I can to save cycles here.. if the timer can reset itself that might shave a little more off..
2011-11-13T16:11:26 < BadDwarf> trying to read the mfm pulse stream coming from a (low density) floppy drive.. avg pulse widths should be 4us, 6us, and 8us.. but the disks are OLD, and the data is kinda blurry.. so the 4 can sometimes be anywhere from 3 to 5.. which makes guessing if its a 4 or a 6 a bit hard..
2011-11-13T16:12:34 < BadDwarf> so the more I can get from timers & dma, the more time I have to do analysis on the data before I run out of ram.. (or alternatively, the more time I have to flush the data to external storage.. ) .. 1 track is up to 56k pulses.. which is a struggle on a 20k ram device
2011-11-13T16:42:09 < jpa-> use dma
2011-11-13T16:49:51 -!- Xamusk [~X@186.221.10.157] has joined ##stm32
2011-11-13T17:02:50 < BadDwarf> I'm using dma for some.. open to suggestions for the rest.. so far I've got the dma request handling moving the captured timer val into my array.. (now with the value resetting after each cap too)..
2011-11-13T17:03:24 < jpa-> yeah, well, that's about it :P
2011-11-13T17:03:29 < BadDwarf> I'm just playing with an sdcard on SPI, will play with dma to see if I can write a decent block from my array straight to it
2011-11-13T17:04:22 < BadDwarf> suspect the write speed of the card may end up being the limiting factor.. hopefully it'll delay less when writing a bunch from my array, than I need to fill the next bunch ;p
2011-11-13T17:21:55 < BadDwarf> well.. I can write 16k out.. in umm.. 1.1 seconds.. ouch.. I think I have about 16ms to achieve that =)
2011-11-13T17:40:58  * BadDwarf wonders if spamming data into a FM25256 might be quicker
2011-11-13T17:44:12 < Xamusk> BadDwarf, the FatFs library supports some DMA usage
2011-11-13T17:44:47 < BadDwarf> I might have a look.. I'm trapped in maple api land tho, so would likely end up rewriting
2011-11-13T17:45:42 < jpa-> multiple block writing to SD cards is faster

2011-11-13T17:56:05 < Xamusk> yeah
2011-11-13T17:56:28 < Xamusk> I got something with c++0xŽs chrono lib, but I found some weird bugs
2011-11-13T17:56:52 < Xamusk> and I still would have to see how to handle it in an OS-less environment
2011-11-13T17:57:57 < Xamusk> and everything I found pointed to using time_t to make a string representation, but time_t is 32-bit
2011-11-13T17:59:08 < Xamusk> I even though about hacking into the stdlib, but that would be a lot of trouble

2011-11-14T06:18:16 < karlp> jpa-: could you give this branch a bit of a play please? https://github.com/karlp/stlink/tree/libwork2
2011-11-14T06:18:51 < karlp> I don't want to break the master yet.  If you have a working flashable file for a 32L board, that would be great
2011-11-14T06:19:18 < karlp> I've got to spend some time getting some 32L demos working for myself now, to make sure things work on those boards too.
2011-11-14T06:19:34 < karlp> the flash programming pieces are still a bit to rigid and make bad assumptions :(
2011-11-14T06:19:48 < karlp> also, man, I should have been in bed hours and hours ago :(
2011-11-14T06:22:52 < karlp> Rious: have you got working F4 flashing with your github top of tree?
2011-11-14T06:23:35 < Rious> karlp: yes, I just pulled in the latest from texans and jnosky
2011-11-14T06:23:51 < karlp> ok, because some of their changes broke the VL code
2011-11-14T06:23:56 < karlp> so I'v ebeen avoiding merging it
2011-11-14T06:23:58 < Rious> I tried it with Lion and Ubuntu
2011-11-14T06:24:17 < karlp> jnosky's code has some really really messy commits that makes it a bit hard to see what bits to try and pull in.
2011-11-14T06:24:50 < karlp> are you using gdb-server to load an elf? or the command line flash tool?
2011-11-14T06:24:53 < Rious> I hadn't looked through the code but I did notice that the change counts were large
2011-11-14T06:25:21 < karlp> I want to make sure f4 works, but I don't have one here yet :)
2011-11-14T06:25:36 < Rious> on Lion gdb worked fine to load flash, on Ubuntu, gdb would look like it worked, but it wouldn't have written to flash
2011-11-14T06:25:54 < karlp> hmm, interesting.
2011-11-14T06:25:54 < Rious> the flash util worked on both Lion and Ubuntu
2011-11-14T06:26:01 < karlp> do you have any other boards? or just the F4?
2011-11-14T06:26:18 < Rious> just the F4, I've got an extra one if you're interested
2011-11-14T06:27:48 < karlp> I am, but now that they're back in stock most places, I'll probably just get one with the next order at work.
2011-11-14T06:28:54 < karlp> well, I'm going to try and update my examples and bits to work on the 32L board this week, then try and browse jnosky's bits and pieces and try and pull in the minimum
2011-11-14T06:29:00 < karlp> but bed calls!

2011-11-14T13:49:46 < zlog> dekar: Log stored at http://tom-itx.dyndns.org:81/~tom-itx/irc/logs/%23%23stm32/2011-11-14.html
2011-11-14T13:51:07 < dekar> is there some non volatile memory on the stm32 which I could use to store 2 bits?
2011-11-14T13:51:25 < dekar> I could use the flash ofc, but it seems to be overkill given that I have to delete whole pages etc
2011-11-14T13:51:38 < karlp> the option bytes have 2 bytes for user data
2011-11-14T13:53:36 < dekar> those to set flash permissions? I don't know whether I want to abuse them :/
2011-11-14T13:54:44 < karlp> reread the docs :) there's two bytes explicitly labelled for user NV storage :)
2011-11-14T13:55:00 < karlp> also, there's some docs on eeprom emulation, which might do what you want
2011-11-14T13:56:18 < dekar> Ah I feel like I want to use those bytes then :)
2011-11-14T14:19:59 < dekar> Those are unaligned bits? -.-"
2011-11-14T14:20:04 < dekar> c'mon st
2011-11-14T14:25:23 < dekar> karlp, I'll use the flash, got that working already. Thanks nonetheless
2011-11-14T14:26:29 < grummund> dekar: there is "backup ram" area which maintains storage even in shutdown, if that helps.
2011-11-14T14:26:36 < grummund> 10 bytes iirc
2011-11-14T14:53:22 < Laurenceb> you can write to flash too
2011-11-14T14:53:34 < Laurenceb> but its not eeprom - the writes are more limited
2011-11-14T15:23:54 < karlp> Rious: how slow is it to program the F4 baord with the current stlink?
2011-11-14T15:24:36 < karlp> it sends 32bits at a time through the debugger, whilethe F1 and L1 flashing uses an sram loader,
2011-11-14T15:24:48 < karlp> I'm wondering how much of a different it really makes
2011-11-14T15:30:41 < jpa-> karlp: not sure about startup, but programming is not any faster
2011-11-14T15:30:55 < jpa-> though it gives more debug info if not using -v0 :D
2011-11-14T15:31:38 < karlp> oh, mor ein some places, less in others.  you're on the top of the libwork2 branch right?
2011-11-14T15:31:48 < karlp> that should be a lot less output by default, with no -v flags
2011-11-14T15:32:32 < karlp> jpa-: probably only the first startup is faster.  it doesn't have the wait a second, disconnect, wait five seconds, reconnect that used to be needed when it was still mass storage
2011-11-14T15:32:40 < jpa-> oh
2011-11-14T15:33:18 < jpa-> with no -v switches, i'm now getting a lot of this: http://paste.dy.fi/3au/plain
2011-11-14T15:33:31 < karlp> well, yeah :)
2011-11-14T15:33:44 < karlp> that's better than hundreds of pages of readmem32 writemem32
2011-11-14T15:34:10 < karlp> you think that's stilltoo noisy?
2011-11-14T15:34:28 < Laurenceb> is f4 working yet?
2011-11-14T15:34:45 < karlp> yeah, Rious and jnosky and co have it working with texane top of tree
2011-11-14T15:34:51 < karlp> but they broke VL
2011-11-14T15:34:58 < jpa-> hmm.. well i guess i've always had -v0 before then :D
2011-11-14T15:34:58 < karlp> I'm in the process of putting the two together again.

2011-11-14T15:35:31 < karlp> A lot of the stuff in current texane top of tree is a bit kludged together,
2011-11-14T15:35:33 < Laurenceb> your code works fine tho
2011-11-14T15:35:45 < karlp> yeah, as best I can tell, the hacks that got merged in for F4 totally broke F1,
2011-11-14T15:35:51 < Laurenceb> lol
2011-11-14T15:35:51 < karlp> and probably broke L1 as well.
2011-11-14T15:36:03 < karlp> good news, they do actually work for F4 :)
2011-11-14T15:36:18 < karlp> two halfs make a whole eventually
2011-11-14T15:36:20 < Laurenceb> heh
2011-11-14T15:38:40 < karlp> hmm, I should be doing my day job, but they FORGOT TO RESTOCK THE COFFEE
2011-11-14T15:38:50 < karlp> how am I expected to work on  monday without coffee?
2011-11-14T15:39:38 < jpa-> your job is to restock the coffee
2011-11-14T15:39:59  * karlp grins
2011-11-14T15:40:09 < BrainDamage> wire a stm32 to the pantry so it checks leftover levels, and automatically orders more
2011-11-14T15:41:04 < jpa-> wire a stm32 to your brain so that it stimulates the same areas as coffee
2011-11-14T15:41:29 < jpa-> then hope that you don't have too many brain cells for 2 DAC channels to interface
2011-11-14T15:43:36 < Rious> karlp: it takes a bit, I'll time it with the discovery demo
2011-11-14T15:44:03 < Rious> I also got gdb writing to work, I just needed to update my toolchain
2011-11-14T15:47:41 < karlp> I have some doubts that the gdb writing is as solid as it should be.  as best I can tell, gdb asks st-util to write each section separately.
2011-11-14T15:47:47 < karlp> and teh tool erases the pages necessary
2011-11-14T15:48:00 < Laurenceb> hehe theres a load of prisoners cleaning my street
2011-11-14T15:48:04 < karlp> so for adjoining sections, in the same page, I have my doubts that it works properly.
2011-11-14T15:48:09 < Laurenceb> crazy
2011-11-14T15:48:15 < karlp> but that can be dealt with later. :)
2011-11-14T15:48:21 < jpa-> eek :D
2011-11-14T15:48:36 < karlp> the flash tool from the command line just writes it as one big block
2011-11-14T15:48:40 < Laurenceb> david cameron comes up with some crazy stuff
2011-11-14T15:49:16 < Laurenceb> if they gave them some decent tools they'd be able to do some work
2011-11-14T15:49:37 < Laurenceb> but i guess thats not the point - guess im supposed to get rotten fruit now
2011-11-14T15:55:59 < Rious> karlp: That sounds right, it writes at 920 bytes/sec for me, and definitely breaks the write into sections
2011-11-14T15:58:15 < Rious> The flash util seems to take just as long and also write in sections
2011-11-14T15:58:28 < Laurenceb> 1KB here
2011-11-14T15:58:46 < Laurenceb> a bit slow :(
2011-11-14T15:58:59 < Laurenceb> serial loader is several times faster

2011-11-14T16:05:47 < karlp> flash util should write one binary, it doesn't break up the sections from the elf like gdb seems to, is what i mean at least.
2011-11-14T16:06:51 < Rious> understood, that seems to be true, just breaks up flash sections
2011-11-14T16:07:01 < jpa-> i should check if it actually writes wrong currently
2011-11-14T16:07:12 < jpa-> but my dev board is 3 meters away
2011-11-14T16:07:27 < karlp> jpa-: only via gdb, flash from the command line just writes the binary to the address.
2011-11-14T16:07:44 < jpa-> i don't use your flash from command line, i use gdb :)
2011-11-14T16:07:48 < karlp> :)
2011-11-14T16:07:54 < karlp> because gdb lets you debug!
2011-11-14T16:08:04 < karlp> otherwise you mighta s well use the serial bootloader
2011-11-14T16:08:15 < jpa-> indeed
2011-11-14T16:09:06 < karlp> at least for now, it should be possible to make it much faster
2011-11-14T16:09:19 < karlp> but, reliability first
2011-11-14T16:09:54 < jpa-> no, speed first!
2011-11-14T16:10:12 < jpa-> i don't care if i have to debug programmer bugs for 2 weeks, as long as it happens fast! ,)

2011-11-14T17:11:54 < karlp> I was afraid that the page erase before each write would trample a previously written block.

2011-11-15T00:01:18 <+Steffanx> So I didn't use it :)
2011-11-15T00:34:10 < Laurenceb_> it might be that have a pull up not a pull down on the WKUP pin
2011-11-15T00:34:32 < Laurenceb_> that woulds explain why i boots up if i increase VDD from 3 to 3.3v
2011-11-15T00:34:35 < Laurenceb_> *it
2011-11-15T00:35:00 < Laurenceb_> but i still cant explain why the stm32 is effectively dead after a power on reset
2011-11-15T00:35:21 < Laurenceb_> i have to cycle VDD from 3.3v to 3v then 3.3v to make it work
2011-11-15T00:35:44 < Laurenceb_> and theres a weird oscillating signal from 500mv to 1.2v on the WKUP pin
2011-11-15T00:36:02 < Laurenceb_> JTAG is nonresponsive when it goes into "weird mode"

2011-11-15T01:00:08 < karlp> hello again
2011-11-15T01:00:14 < karlp> sorry, I just missed you :)
2011-11-15T01:00:45 < jnosky> Ahh had a bit of trubls
2011-11-15T01:01:15 < jnosky> So I tried to be careful to leave the other boards alone when I added F4 support
2011-11-15T01:01:22 < karlp> yeah, I don't think it was you per se.
2011-11-15T01:01:39 < karlp> texane merged a bunch of stuff, and it got broken.
2011-11-15T01:01:40 < jnosky> Mostly I just left the old code as is and made mine conditional on the chipid
2011-11-15T01:01:59 < jnosky> The old code was using coreid
2011-11-15T01:02:01 < karlp> yeah, I've spent a bit of time the last couple of days going over it, and I think I've seen all the bits youadded now,
2011-11-15T01:02:07 < karlp> yeah, coreid was never going to be very portable
2011-11-15T01:02:21 < jnosky> But the f4 and the l are both the same coreid
2011-11-15T01:02:40 < karlp> the way the gdbserver was using the chip ids, was right, but it needed to be pulled into the core library, not only in the gdb server stuff
2011-11-15T01:02:56 < jnosky> I didnt know all the other chipids, so i left those as coreid still
2011-11-15T01:03:13 < jnosky> The mentality being dont touch the others "working" stuff
2011-11-15T01:03:16 < karlp> yeah, I'm trying to put together a list of what's actually been tested with what :)
2011-11-15T01:03:51 < jnosky> The common code really ought to have some function to get all the flash params
2011-11-15T01:04:00 < jnosky> The flash utility is using #defines
2011-11-15T01:04:08 < jnosky> and the server uses the xml
2011-11-15T01:04:23 < karlp> yeah, that's what I've nearly finished in my branch
2011-11-15T01:04:29 < karlp> just not with all your tweaks for the F4 yet.
2011-11-15T01:04:50 < karlp> I've nto asked texane to merge it yet, because I know people are using it as is for the F4
2011-11-15T01:05:24 < jnosky> All I did really was add a chipid to sl
2011-11-15T01:05:33 < jnosky> and made a bunch of code conditional on that
2011-11-15T01:05:54 < karlp> things like is_flash_locked, that have if/elses for chipids, I'd rather see those parameters added to the chip_params, so each utility method can just use the right params pulle out of the chip params struct
2011-11-15T01:06:08 < jnosky> All I have is the f4, thats what prompted me to fix all that
2011-11-15T01:06:15 < karlp> good good.
2011-11-15T01:06:24 < karlp> I only have the 32VL and 32L boards :)
2011-11-15T01:06:46 < karlp> we'll get it worked out, I just wanted you to have a look a twhat was going on for the other boards in the background :)
2011-11-15T01:07:06 < karlp> I know that the F4's sector programming was never going to be quite the same
2011-11-15T01:07:21 < karlp> there's still plenty of tidying up to do, and testing with more targets yet.
2011-11-15T01:07:41 < jnosky> OK well im pretty well satisfied so far in how it all works for the f4 functional wise
2011-11-15T01:07:46 < karlp> excellent.
2011-11-15T01:07:51 < jnosky> Ive tested the full range of flash space
2011-11-15T01:07:59 < karlp> loading elfs to sram and flash are all good, debugging?
2011-11-15T01:08:07 < karlp> breakpoints and all that?
2011-11-15T01:08:20 < jnosky> and created a big elf to test the gdbservers ability to load it
2011-11-15T01:09:01 < karlp> you're on windows right?
2011-11-15T01:09:10 < jnosky> (not that I have a big ass project file, i just did a .incbin to the startup code ;)
2011-11-15T01:09:34 < jnosky> I like to use eclipse for all my cross dev stuff
2011-11-15T01:09:54 < jnosky> So I get the full src debugging experience with the st-util
2011-11-15T01:09:55 < karlp> you're just using this demo? https://github.com/texane/stlink/tree/master/example/stm32f4/Projects/discovery_demo
2011-11-15T01:10:41 < jnosky> mainly ive been playing with IO_Toggle to get my environment all set up
2011-11-15T01:11:01 < jnosky> But I did manage to get the make file made for the discovery demo
2011-11-15T01:11:07 < jnosky> and gdb loaded it
2011-11-15T01:11:20 < karlp> ok. sweet.
2011-11-15T01:11:24 < jnosky> It seems to work, but im waiting for my usb otg cable
2011-11-15T01:11:34 < jnosky> The lights flash like they should
2011-11-15T01:11:43 < jnosky> and the mems seems to work, so I assume its all good
2011-11-15T01:11:57 < karlp> I'm hoping to get an F4 here in the next few weeks, but I'm going to try and mergeyour code into mine first.
2011-11-15T01:12:09 < karlp> it sounds like you don't have many other things left to do for F4 support now?
2011-11-15T01:12:17 < jnosky> That make file was a motherfucker
2011-11-15T01:12:26 < jnosky> You cant find them in the stm stuff
2011-11-15T01:12:34 < jnosky> They want you to use the big 3
2011-11-15T01:12:39 < karlp> yeah, tell me about it.
2011-11-15T01:12:50 < karlp> I'm struggling with startup files for the 32L board
2011-11-15T01:13:07 < karlp> have you been using other STM32 chips before this?
2011-11-15T01:13:41 < jnosky> No, ive used the LPC2148
2011-11-15T01:14:28 < jnosky> I got those startup files from the big 3 releases
2011-11-15T01:14:40 < jnosky> Than I just hadda figure out how to make the make
2011-11-15T01:14:55 < jnosky> I *think* I got it right ;)
2011-11-15T01:15:03 < karlp> does anyone here have any good open source startup files for any of these platforms?
2011-11-15T01:15:17 < karlp> how's the F4 after using the arm7tdmi?
2011-11-15T01:15:44 < jnosky> Well its a lot different thats fer sure ;)
2011-11-15T01:15:56 < jnosky> Damn this chip has peripherals up the ass
2011-11-15T01:16:19 < jnosky> I read "world fastest uC"
2011-11-15T01:16:24 < jnosky> That got me interested ;)
2011-11-15T01:17:16 < jnosky> I think the attolic is what I used for startups
2011-11-15T01:17:59 < jnosky> The biggest issue was this variable page thing business
2011-11-15T01:18:07 < jnosky> It didnt fit well into the existing code
2011-11-15T01:18:53 < karlp> yeah, it's what, 4 pages of 16k, one of 64, and the rest 128k or somethign silly?
2011-11-15T01:18:59 < jnosky> lol yup
2011-11-15T01:19:01 < karlp> it is however, almost identical to the F2,
2011-11-15T01:19:17 < karlp> hwoever, there's no F2 discovery board, and no-one has ever mentioned using this with an F2
2011-11-15T01:19:25 < karlp> so... it never got worked on :)
2011-11-15T01:19:37 < karlp> it's been influx a lot recently.
2011-11-15T01:19:48 < jnosky> Whats an L vs VL -> f# wise?
2011-11-15T01:19:57 < karlp> we'd just started to get it working with the stlinkv2 hardware, when the F4 got announced
2011-11-15T01:20:01 < karlp> and a lot of stuff went up in the air
2011-11-15T01:20:01 < jnosky> Thats confusing as hell
2011-11-15T01:20:06 < karlp> VL is f100
2011-11-15T01:20:13 < karlp> L is the energylite,
2011-11-15T01:20:18 < karlp> it's like somewhere between an F1 and an F2,
2011-11-15T01:20:26 < karlp> with a different flash programming manual
2011-11-15T01:21:01 < jnosky> Yet the L has same chip id as the f4
2011-11-15T01:21:09 < karlp> well, F4 has a broken chip id :)
2011-11-15T01:21:41 < jnosky> Yea and heres another gem I found
2011-11-15T01:21:44 < jnosky> https://my.st.com/public/STe2ecommunities/mcu/Lists/cortex_mx_stm32/DispForm.aspx?ID=19227
2011-11-15T01:22:03 < jnosky> I couldnt understand why i couldnt get the flash size right
2011-11-15T01:22:23 < karlp> yycuk, that's not on the errata sheet
2011-11-15T01:22:23 < jnosky> I finally found it in rm90
2011-11-15T01:22:32 < jnosky> The xml was right!
2011-11-15T01:22:41 < jnosky> I thought the reg was wrong
2011-11-15T01:23:00 < jnosky> So I have no idea where it really is still
2011-11-15T01:23:36 < jnosky> So I had to harcode that in the server
2011-11-15T01:24:12 < jnosky> So does your device work with whats on texane right now?
2011-11-15T01:24:19 < karlp> no, not at all.
2011-11-15T01:24:25 < karlp> current texane top of tree works for F4 only,
2011-11-15T01:24:34 < karlp> might work for L1 and F2, but no information
2011-11-15T01:24:39 < jnosky> Did it work before I stepped on all that code?
2011-11-15T01:24:50 < karlp> I have an L1 board, but I don't have any decent code that I can verify it works with yet
2011-11-15T01:24:57 < karlp> not sure.
2011-11-15T01:25:18 < karlp> I was in the process of ripping out the old nasty scsi pass through stuff that didnt work on macOS and windows,
2011-11-15T01:25:18 < jnosky> You have what hw again?
2011-11-15T01:25:26 < karlp> at about the same time as the F4 stuff started landing
2011-11-15T01:25:32 < karlp> so mine's not even really compatible anymore
2011-11-15T01:25:42 < jnosky> got mine for free :)
2011-11-15T01:25:47 < karlp> I have a VL discovery board, (F1) and a 32L discovery board (L1)
2011-11-15T01:25:51 < karlp> yeah, you and everyone else
2011-11-15T01:25:59 < karlp> I don't live in north america :)
2011-11-15T01:26:26 < karlp> I'm just trying to work out the best way to whip git to leave you name on all these commits :)
2011-11-15T01:26:47 < karlp> but they've diverged a fair bit, I wasn't expecting so much more work to come in :)
2011-11-15T01:28:12 < jnosky> Im very very new to github
2011-11-15T01:28:33 < jnosky> My first pull request was a reall mess for texane, but he needed my code in there, so he stuck it out
2011-11-15T01:28:38 < karlp> yeah, i saw
2011-11-15T01:28:56 < karlp> I was, umm, ignoring it for a while, and hoping it would all get better :)
2011-11-15T01:29:09 < jnosky> After the merge I started over, and recloned from him
2011-11-15T01:29:20 < jnosky> Last few commits I think went fine
2011-11-15T01:29:22 < karlp> yeah, your recent ones are whole lot eastier to follow
2011-11-15T01:29:44 < jnosky> Well there was soo much todo to get all the f4 stuff in, I was all over the place
2011-11-15T01:29:51 < karlp> yeah, no problems
2011-11-15T01:29:53 < karlp> totally understand
2011-11-15T01:29:55 < jnosky> But the code is really not that big
2011-11-15T01:30:07 < jnosky> So I understand the whole thing pretty well now
2011-11-15T01:30:18 < karlp> no, the examples can be distracting at time, they're much bigger than the rest of the code
2011-11-15T01:30:21 < karlp> good good.
2011-11-15T01:30:23 < jnosky> If you like, when yours is working, I could pull it into mine
2011-11-15T01:30:30 < karlp> mine's working now.
2011-11-15T01:30:38 < karlp> you can pull the libwork2 branch in if you want,
2011-11-15T01:30:57 < karlp> or at least, have a play with it,
2011-11-15T01:31:14 < karlp> but that's what I'm doing right now, pulling your latest stuff in, and putting it together again.
2011-11-15T01:31:28 < karlp> well, right now I'm gossipping
2011-11-15T01:31:34 < karlp> but soon (tm)
2011-11-15T01:34:05 < jnosky> the gdbserver code shouldnt have hurt you
2011-11-15T01:34:09 < karlp> no, it was in the core.
2011-11-15T01:34:16 < jnosky> I basically just added the f4 template
2011-11-15T01:34:28 < jnosky> Im looking at it now
2011-11-15T01:34:40 < karlp> I think it was other stuff that texane was playing around with at the same time that just came in all together
2011-11-15T01:36:16 < jnosky> <karlp> no, it was in the core.
2011-11-15T01:36:30 < jnosky> You mean common.c ?
2011-11-15T01:36:34 < karlp> yeah,
2011-11-15T01:37:23 < karlp> I think it was https://github.com/karlp/stlink/blob/libwork2/src/stlink-common.c#L1274
2011-11-15T01:37:31 < karlp> that had been changed to "step" instead of run for some reason.
2011-11-15T01:38:19 < jnosky> I put the chipid into the sl structure
2011-11-15T01:38:37 < karlp> yeah, I'd done that too
2011-11-15T01:38:52 < karlp> it's all good, it shouldn't be much for me to get this all in one palce again :)
2011-11-15T01:39:04 < jnosky> int stlink_load_device_params(stlink_t *sl)
2011-11-15T01:39:13 < jnosky> I like that one, its just was thinking
2011-11-15T01:39:21 < jnosky> what I was thinkin too
2011-11-15T01:39:23 < karlp> yeah, that's what I want to pull yoru stuff into
2011-11-15T01:39:29 < karlp> set up the flash reg params there
2011-11-15T01:39:36 < karlp> get it all out of each individual method
2011-11-15T01:39:52 < karlp> just read as much as we can when the device is opened in the first place
2011-11-15T01:40:04 < jnosky> The pagesize was the big cluster fuck about the whole thing
2011-11-15T01:40:23 < jnosky> All the other code assumed it never changed
2011-11-15T01:40:43 < jnosky> So what I did was just let it get filled like it used to be
2011-11-15T01:40:44 < karlp> which is why I desparately wanted to get it from gdb-server into the common code
2011-11-15T01:41:06 < jnosky> The stlink_claculate_pagesize
2011-11-15T01:41:12 < jnosky> is called here and there
2011-11-15T01:41:30 < jnosky> It returns the pre filled static number, unless its an f4
2011-11-15T01:42:06 < jnosky> So that sub, refills the sl-pagesize for f4
2011-11-15T01:42:15 < jnosky> or just leaves it alone if its not
2011-11-15T01:42:48 < jnosky> I dont know what to do about the xml in the server
2011-11-15T01:42:59 < jnosky> That was too far different from what I needed
2011-11-15T01:43:09 < karlp> unfortunately, that's what gdb needs apparently
2011-11-15T01:43:11 < karlp> so too bad
2011-11-15T01:43:17 < jnosky> It dont matter really tho
2011-11-15T01:43:29 < jnosky> The pc has tons of codespace
2011-11-15T01:43:31 < karlp> or at least, someone with far far more knowledge of gdb remote protocols needs to work on it.

2011-11-15T01:43:45 < jnosky> So a seperate xml, for the device was the least painful by far
2011-11-15T01:44:00 < jnosky> No i fixed it it worked
2011-11-15T01:44:04 < jnosky> I was shitting tho
2011-11-15T01:44:14 < jnosky> Cause I thought the gdb wasnt gonna like this
2011-11-15T01:44:26 < jnosky> multiple definations of flash
2011-11-15T01:45:03 < jnosky> So I simply tried making multiple block sizes based on the address
2011-11-15T01:45:09 < jnosky> and it worked!
2011-11-15T01:48:11 < jnosky> So these other hw versions flash by a loader in ram it seems?
2011-11-15T01:48:42 < karlp> yeah, not really sure if it's important or not though
2011-11-15T01:49:46 < karlp> might be able to increase performance that way.
2011-11-15T01:49:52 < karlp> might not make much difference.
2011-11-15T01:50:03 < karlp> leaving it as is until we have all of them working first
2011-11-15T01:51:26 < jnosky> Flashing is super slow
2011-11-15T01:51:45 < jnosky> There is a limit on how many 0 pits nay be burned per write
2011-11-15T01:52:10 < karlp> yeah, based on voltage
2011-11-15T01:52:11 < karlp> hooray
2011-11-15T01:52:22 < karlp> good luck being able to work that out from the programmer in software :(
2011-11-15T01:52:29 < jnosky> I suspect the usb is the cuplrit tho really
2011-11-15T01:52:47 < jnosky> Each 32 bit write I think is chewing up a packet
2011-11-15T01:52:58 < jnosky> And since usb is host controlled
2011-11-15T01:53:10 < jnosky> that happens prolly once per msec
2011-11-15T01:53:25 < karlp> currently, yes.
2011-11-15T01:53:41 < jnosky> Reading is way fast tho
2011-11-15T01:53:41 < karlp> a ram loader should get around that
2011-11-15T01:53:54 < karlp> yeah, the usb commands let us read/write more than one word at at ime
2011-11-15T01:53:58 < karlp> so it should get faster over time
2011-11-15T01:55:07 < jnosky> I had this problem on the lpc2148 too
2011-11-15T01:55:23 < jnosky> Not for the environemt setup, but a general thruput issue
2011-11-15T01:55:40 < jnosky> Making the packets as large as possible helped a great deal
2011-11-15T01:56:21 < jnosky> I didnt want to open that can of worms here tho :)
2011-11-15T01:56:32 < karlp> not yet :)
2011-11-15T01:56:39 < jnosky> I just wanted to be able to load and debug the demos in elcipse
2011-11-15T01:56:45 < jnosky> Im a sucker for an ide
2011-11-15T01:56:55 < jnosky> visual studio debugger is hard to beat
2011-11-15T01:57:05 < jnosky> eclipse comes as close as I can to that
2011-11-15T01:57:26 < jnosky> Clicking on a src line to set a break is really the key
2011-11-15T01:57:48 < jnosky> I use eclipse for ppc too
2011-11-15T01:58:08 < karlp> heh, I've never actually managed to get the demos to build.

2011-11-15T01:58:33 < jnosky> Those demos are for specific devices
2011-11-15T01:58:41 < jnosky> Im not sure which ones
2011-11-15T01:58:52 < jnosky> But they arent even close for the f4
2011-11-15T01:58:55 < karlp> no, I mean, the demo code downloadable from ST, for the devices I have
2011-11-15T01:59:05 < karlp> I've not managed to get them compiled and flashed (yet)
2011-11-15T01:59:53 < jnosky> Ahh ic, the 2 i uploaded are from the st srcs
2011-11-15T02:00:09 < jnosky> They basically needed startup code and make files
2011-11-15T02:00:21 < karlp> yeah, and startup code is somethign I was sorely lacking
2011-11-15T02:00:45 < karlp> anyway, I'm going to hack for a bit,
2011-11-15T02:00:48 < jnosky> Werent there any .S files in the srcs they provide?
2011-11-15T02:01:05 < karlp> I'll probably send you some code later this week to try out, see how it goes.
2011-11-15T02:01:19 < jnosky> In the toolchain project templates I found em
2011-11-15T02:01:26 < jnosky> but no makes
2011-11-15T02:02:05 < jnosky> Sure ill be happy to test out some stuff
2011-11-15T02:02:16 < jnosky> I was starting to think I was the only one interested
2011-11-15T02:02:22 < karlp> oh no, plenty :)

2011-11-15T02:16:38 < jnosky> Im slightly embarrassed to admit win ;)
2011-11-15T02:16:57 < Rious> yes, thank you for getting the stm32f4 flash stuff to work

2011-11-15T02:17:39 < jnosky> Ahh yer welcome, im glad to hear from someone else it worked for
2011-11-15T02:18:04 < Rious> I was shocked that the discovery demo would compile so easily w/ gcc
2011-11-15T02:20:39 < jnosky> Ive done some cross dev for the lpc2148 under eclipse, so I wanted to set up the same basic environment for the freebe board i got
2011-11-15T02:21:15 < jnosky> truestudio woulda been cheating ;)
2011-11-15T02:21:18 < Rious> I've done quite a bit of AVR dev, and some MSP430, hadn't done any ARM, mostly because of cost
2011-11-15T02:22:23 < jnosky> I basically use the lpc to animate my hacks, since pcs no longer have lpt ports really
2011-11-15T02:23:09 < jnosky> I like how this chip may be a device as well as a host
2011-11-15T02:24:33 < Rious> yes, that is very cool, I also like the DAC
2011-11-15T02:26:53 < jnosky> Now that I have the basic framework setup, I should be able to at least build the other examples
2011-11-15T02:28:29 < jnosky> Have you tried debugging the discovery demo yet under the gdbserver?
2011-11-15T02:31:22 < karlp> Rious: texane actually had a bit to do with that I think, he doesn't talk much, but he knows someone at ST
2011-11-15T02:31:41 < karlp> they were initially very surprised at how many linux/gcc people were using the discovery boards
2011-11-15T02:31:58 < karlp> and they had to readjust how they were doing thigns, which is why the f4 is apparently the easiest
2011-11-15T02:32:04 < karlp> also, why they fixed the broken stlinkv1 hardware
2011-11-15T02:32:55 < Rious> I'm glad to hear that there are companies that pay attention to that sort of thing
2011-11-15T02:38:40 < karlp> well, only when they got yelled at :)
2011-11-15T02:38:46 < karlp> and it's still far from perfect
2011-11-15T02:39:05 < karlp> texane's words were, "they were rather surprised, and are taking it as a learning experience"
2011-11-15T02:39:53 < karlp> jnosky: the array of devics that is in gdbserver in main, with the flash regs and chipids and so on, did you have to change anything there? or just in the xml templates?
2011-11-15T02:40:01 < karlp> you only touched the f4 entry right?

2011-11-15T04:06:33 < jnosky> Then I just strcpy it
2011-11-15T04:07:40 < jnosky> karl so then you have have fetched upstream and merged from texane?
2011-11-15T04:20:16 < karlp> yep
2011-11-15T04:20:28 < karlp> that branch should ahve all of your changes, and all of mine, and all of all the things
2011-11-15T04:24:57 < jnosky> As I said im a git noob, so what would be the preffered wourse of action?
2011-11-15T04:25:04 < jnosky> course
2011-11-15T04:25:45 < karlp> umm, an easy way of doign it is to clone my repo completely new,
2011-11-15T04:25:54 < karlp> make sure to checkout the right branch
2011-11-15T04:25:56 < karlp> and test it out
2011-11-15T04:25:57 < jnosky> Thats what I was thinkin
2011-11-15T04:26:12 < karlp> you can also do git remote add karl-gh http://asdfasdf
2011-11-15T04:26:17 < karlp> then git fetch karl-gh
2011-11-15T04:26:33 < karlp> and git checkout -b mytest karl-gh/future_f1plus_f4
2011-11-15T04:26:56 < karlp> which will giv eyou a branch in your own local repo that tracks my branch

2011-11-15T11:54:36 < karlp> I'll break it out to a separate (probably optional) verification step, so that it can be skipped on F4's for now.
2011-11-15T11:55:02 < karlp> does it work once you ifdef out that verification?

2011-11-15T17:22:01 < mansfeld> hi there
2011-11-15T17:22:16 < jpa-> hi here
2011-11-15T17:22:16 < mansfeld> has anyone here used the simplemac library for the stm32w?
2011-11-15T17:41:37 < karlp> not I, but I'd love to hear how you find the stm32w
2011-11-15T17:42:38 < mansfeld> I'll be sure to let you know once I get this damn library to compile :]
2011-11-15T17:44:18 < mansfeld> it seems like a really nice chip though, I'm just a little confused by the lack of documentation (where are the RF registers described? I can't get the source code and there's no mention of them in the datasheet...)
2011-11-15T17:50:06 < Laurenceb> :S
2011-11-15T17:50:21 < karlp> are you talking about UM0893? the STM32W108xx Simple MAC library from ST?

2011-11-15T18:27:18 < BadDorf> hi.. I know I can do DMA from timer capture to memory, and from memory to SPI tx, and the datasheet mentions dma from peripheral to peripheral.. could I do DMA straight from timer capture to SPI (tx) ? what are the restrictions ? do I have to make sure the timer channel is on the same dma channel as the chosen spi tx ? not sure how the dma channel -> peripheral table applies in peripheral to peripheral
2011-11-15T18:29:29 < jpa-> the dma channel matters only for the dma trigger source
2011-11-15T18:29:51 < jpa-> you can do that if you know that your spi is always faster than the timer
2011-11-15T18:32:12 < BadDorf> it should be, the spi tx is going to an spi fram that writes at spi bus speed, and the timer should trigger at most every 1us or so (normal 4us min)
2011-11-15T18:32:36 < BadDorf> and, thanks for the info on the dma chan table =)
2011-11-15T18:34:26 < BadDorf> sounds like I can just tweak my existing dma from input capture to mem, to point at the spi tx instead =) (and do a little pre-setup to put the fram into write data mode.. ) then enable the timer, wait till the dma completes (set max transfers to the fram size), at which point I've got an fram full of capture data.. this could be pure awesome on a stick ;p
2011-11-15T18:34:47 < jpa-> :)
2011-11-15T18:34:49 < BadDorf> scary when the hardware does almost all the work !
2011-11-15T18:37:15 < jpa-> indeed, and does it behind your back!
2011-11-15T18:37:50 < BadDorf> aye.. at this rate I may actually have the time to process the fram data back & push it down to the sdcard =)
2011-11-15T18:37:54 < jpa-> mind your word sizes though.. iirc the dma unit has some support to do 16bit -> 8bit conversion which you'll probably need
2011-11-15T18:38:09 < BadDorf> sort of.. I only want 8bit resolution on the timer anyways
2011-11-15T18:39:10 < BadDorf> I'm capturing mfm data from a floppy drive, so the timer vals represent time between pulses.. they _should_ be 4us, 6us, and 8us, but the drive is a physical thing with a lump of plastic spinning at 300rpm, and the media is OLLLD.. so they come back a lot fuzzier than that
2011-11-15T18:39:55 < jpa-> did you get it to reset?
2011-11-15T18:40:00 < BadDorf> yup thanks
2011-11-15T18:40:04 < jpa-> nice :)
2011-11-15T18:40:31 < BadDorf> so basically using dma & the timer, I've got a self filling data source representing a tracks worth of pulse widths..
2011-11-15T18:40:40 < BadDorf> which is just .. insane =)
2011-11-15T18:42:10 < BadDorf> shame the dma can't do bit offset transfers ;-) then I could use it to realign the data afterward too
2011-11-15T18:42:36 < BadDorf> but I suspect I'm thinking far too fondly of the blitter in the amiga =)
2011-11-15T19:46:59 < jnosky> Yep karl it seems to work with that if(0)
2011-11-15T19:47:19 < jnosky> I have not verified with test patterns, but it looks like it worked
2011-11-15T19:47:35 < jnosky> I have not verified by debugging either
2011-11-15T19:48:25 < jnosky> Yknow whats odd is, when I "load IOToggle.elf" after flash the target doesnt reset, ie: it doesnt run right unless I remove power
2011-11-15T19:48:45 < jnosky> It mighta been that way with my code too, I gotta look into that

2011-11-15T21:03:23 < karlp> bu "kill" then "run" will start it properly.
2011-11-15T21:03:56 < karlp> if the #if 0 bits works, I'll add them now and ask texane to pull them.
2011-11-15T21:04:02 < Rious> when I got the error with gdb, I was able to continue without issue
2011-11-15T21:07:07 < jnosky> Rious you had the timeout with the #if(0) in there?
2011-11-15T21:11:27 < karlp> that timeout looks like the rx buffer ran out of ram? like without the #if 0
2011-11-15T21:15:25 < BrainDamage> btw karlp, your master is still unable to flash to my vl board :/

2011-11-15T21:18:03 < Rious> no, I did not have the #if

2011-11-15T23:03:37 < Tom_itx> yeah avr does
2011-11-15T23:03:53 < Tom_itx> or internal ref
2011-11-15T23:03:56 < Laurenceb_> this sucks a lot for me
2011-11-15T23:04:10 < Laurenceb_> as all my EGC frontend hardware is now on a sperate rail
2011-11-15T23:04:20 < Laurenceb_> from VDDA
2011-11-15T23:04:42 < Laurenceb_> so the front end can be turned off in standby mode
2011-11-15T23:05:03 < Laurenceb_>  - its a commercial medical datalogger im working on
2011-11-15T23:07:00 < Laurenceb_> i dont see why the WKUP hardware couldnt have been made to run off VBAT
2011-11-15T23:07:08 < Laurenceb_> that would solve these issues
2011-11-15T23:08:25 < Laurenceb_> then use one of the VBAT domain pins as the WKUP
2011-11-15T23:16:26 < Laurenceb_> karlp: so you live in iceland huh?
2011-11-15T23:17:30 < Laurenceb_> i hate to think what the temperature is there now
2011-11-15T23:19:41 < BrainDamage> I'd love to visit iceland
2011-11-15T23:20:02 < Laurenceb_> in summer XD
2011-11-15T23:32:36 < jnosky> So how exactly does the server reset the target after a flash?
2011-11-15T23:32:44 < jnosky> A jump thru the reset vecotor isnt hard enuf it seems
2011-11-15T23:33:39 < jnosky> When you first load an app, like IO_toggle it will continue, assuming IOToggle was already flashed
2011-11-15T23:33:58 < jnosky> So then if you load say the demo, it will get stuck in startup code
2011-11-15T23:34:15 < jnosky> Then you have to POR
2011-11-15T23:34:24 < jnosky> after that you can load and cont on the demo
2011-11-15T23:34:57 < jnosky> Its like the reset isnt a hard reset, and the peripheral bus is jammed up maybe
2011-11-15T23:40:42 < jnosky> in my mind, when I load IOToggle.elf, it should cont or run
2011-11-15T23:41:04 < jnosky> and from the same session, I should then be able to load the discovery demo, and run that
2011-11-15T23:41:11 < jnosky> without removing power at all
2011-11-15T23:44:45 < jnosky> without regard to what was previously flashed...

2011-11-16T01:16:45 < karlp> Laurenceb_: yes, I'm in iceland.  it's 11C right now, which is maybe a little warmer than normal, but not reall out of range.
2011-11-16T01:16:51 < karlp> it does't really get very cold here
2011-11-16T01:16:58 < Laurenceb_> lmao
2011-11-16T01:17:00 < karlp> new york city is far colder in winter
2011-11-16T01:17:02 < Laurenceb_> 7C here in uk
2011-11-16T01:17:09 < karlp> hehe
2011-11-16T01:17:19 < Laurenceb_> was -22C in my workshop last winter :S
2011-11-16T01:17:32 < Laurenceb_> had to deice my monitor
2011-11-16T01:17:54 < karlp> hehe
2011-11-16T01:17:55 < Laurenceb_> so everyone speaks english over there?
2011-11-16T01:18:46 < karlp> jnosky: not sure, I have an elf that I made with the atollic tools, that loads, continues and works no problems, and then if I load one of the other ones, like from the libopencm3 demos, it loads, and I can kill and run, but not continue.
2011-11-16T01:19:01 < karlp> Laurenceb_: most people, I'm actually a native english speaker, and still learning icelandic :)
2011-11-16T01:20:00 < Laurenceb_> yeah i stumbled across your website :P
2011-11-16T01:21:13 < Laurenceb_> i might go next summer then

2011-11-16T02:35:00 < karlp> yep
2011-11-16T02:35:20 < karlp> brewing, not finished yet :)
2011-11-16T02:36:33 < BrainDamage> I tried again now, flashing worked
2011-11-16T02:36:38 < BrainDamage> thanks for your help
2011-11-16T02:37:02 < BrainDamage> ( after having stripped the elf to a bin container ofc )
2011-11-16T02:39:40 < BrainDamage> sorry for being an idiot, but I don't grasp well how the toolchain works here
2011-11-16T02:40:06 < BrainDamage> when I flash the blink example, the program will be in a diff memory address
2011-11-16T02:40:20 < BrainDamage> does the stm32 also looks there at boot to see if there's anything to run?
2011-11-16T02:40:43 < BrainDamage> if so, why doesn't it still blink? :/
2011-11-16T02:50:51 < grummund> presumably if you were using the debugger to run code from ram then the debugger would take care it
2011-11-16T02:51:48 < BrainDamage> not using the debugger
2011-11-16T02:52:22 < grummund> i may have misunderstood the question
2011-11-16T02:54:01 < BrainDamage> ok, I want to run _anything_ on the board, I accidentally wiped flash in the past, so gdb loading to ram doesn't work because after you do, all registers have screwed pointers
2011-11-16T02:54:30 < BrainDamage> I'd have to reflash part of the orig firmware to get that functionality back
2011-11-16T02:54:50 < BrainDamage> so I'm trying to run at least from flash
2011-11-16T02:55:09 < grummund> um, what's that then... a bootloader?
2011-11-16T02:55:46  * grummund uses JTAG to flash, and never attempted to run from ram.
2011-11-16T02:55:49 < BrainDamage> so I proceeded to change the memory offset in the blink example from 0x2000000 to 0x8000000, strip the elf to bin, and flashed
2011-11-16T02:56:34 < grummund> what board is this?
2011-11-16T02:56:43 < BrainDamage> 32vl discovery
2011-11-16T02:57:02 < grummund> ok, so that has the onboard programmer (i think)
2011-11-16T02:57:18 < BrainDamage> yup, st-link, version 1
2011-11-16T02:57:53 < grummund> the stm32 boots according to the logic level on two boot pins
2011-11-16T02:58:43 < grummund> not sure what you mean by changing the memory offset though
2011-11-16T02:59:13 < BrainDamage> elf containers contains absolute memory address to my knowledge
2011-11-16T02:59:37 < BrainDamage> aka where to put the beginning of the program
2011-11-16T03:00:29 < grummund> where do you set this memory offset?
2011-11-16T03:01:17 < BrainDamage> compiler
2011-11-16T03:01:25 < BrainDamage> err, linker
2011-11-16T03:01:59 < grummund> i'm still not clear what you mean... as a command line option?

2011-11-16T03:03:39 < karlp> BrainDamage: get this: http://libopencm3.org/wiki/Downloads
2011-11-16T03:03:49 < karlp> even if you don't want the libraries,
2011-11-16T03:03:56 < karlp> it has examples for the VL board, and they all work
2011-11-16T03:04:04 < karlp> very much unlike the examples in stlink :)
2011-11-16T03:04:25 < BrainDamage> thanks :)
2011-11-16T03:04:39 < karlp> we've made flashing work, now I need help getting some good qualitystartup files and linker scripts
2011-11-16T03:05:26 < grummund> i used ones from ST's stdperiph distribution
2011-11-16T03:05:39 < karlp> yeah, I haven't managed to compile anything tha tworks from stdperiph yet.
2011-11-16T03:05:48 < grummund> i have ;)
2011-11-16T03:05:52 < karlp> sorry, I can compile and link, but I'm doing somethign wrong still with startup and linking :)
2011-11-16T03:06:05 < karlp> :P
2011-11-16T03:06:09 < grummund> yes it took a few days to get it

2011-11-16T03:06:27 < BrainDamage> what commit are you on karlp?
2011-11-16T03:07:07 < karlp> grummund: well, I'm hoping now that some kind soul can put together some nice generic reliable libre pieces for me :)
2011-11-16T03:07:10 < karlp> BrainDamage: 6ce8d61 stm32f4-discovery/miniblink: Fix board name
2011-11-16T03:07:41 < karlp> the fancy blink and  miniblink examples as of that commit work with current top of texane's tree :)
2011-11-16T03:07:47 < grummund> stdperiph is not lib friendly the way ST have structured it
2011-11-16T03:08:21 < grummund> needs to be recompiled depending on the hardware setup (specifically clock), so not easy to have a generic lib
2011-11-16T03:08:37 < karlp> grummund: I think I've done the right thing as far as making it generic except for the system clock and startup file, in https://github.com/texane/stlink/tree/master/example/libs_stm/src
2011-11-16T03:08:42 < karlp> locally I have the F4 as well,
2011-11-16T03:08:57 < karlp> but to behonest, it was more just compiler make file wankery
2011-11-16T03:09:00 < karlp> the proof is in the pudding
2011-11-16T03:09:06 < karlp> and so far the pudding is uncooked
2011-11-16T03:09:23 < karlp> oh, and generic, with assert compiled out
2011-11-16T03:09:26 < grummund> tbh, i'd rather use my own Makefile :P
2011-11-16T03:09:49 < BrainDamage> karlp: sorry, should've specified about opencm3
2011-11-16T03:09:52 < karlp> do you just pick and choose individual files from the stdperiph into the makefile?
2011-11-16T03:10:15 < karlp> BrainDamage: 6ce8d61 stm32f4-discovery/miniblink: is a git commit in the opencm3 repo
2011-11-16T03:10:22 < BrainDamage> oh
2011-11-16T03:10:26 < karlp> full commit: 6ce8d610976e79f5c6649d16638b6c1daf45c887
2011-11-16T03:10:34 < karlp> friday nov 11.
2011-11-16T03:10:37 < grummund> yes i link only with the files needed, i don't attempt to build a generic lib
2011-11-16T03:10:44 < BrainDamage> ok, thanks
2011-11-16T03:11:00 < karlp> grummund: it seems to be popular, and functional to do it that way, but just seems to rub me the wrong way :)
2011-11-16T03:11:13 < karlp> I need to let it go I think.
2011-11-16T03:11:33 < BrainDamage> ok, something definetly broken here, I still get the error anyway :7
2011-11-16T03:11:39 < karlp> BrainDamage:  :(
2011-11-16T03:12:17 < grummund> with the benefit of experience :P i can say it's possible to waste an awful amount of time trying to build generic solutions ...
2011-11-16T03:12:32 < BrainDamage> xkcd time?
2011-11-16T03:12:55 < grummund> better to get some projects under the belt first, then go back and revisit how things could be structured to be more efficient
2011-11-16T03:12:59 < karlp> grummund: hehe, you're probably right,
2011-11-16T03:13:07 < karlp> and yeah, that's really what it's time for.
2011-11-16T03:13:11 < BrainDamage> grummund: https://www.xkcd.com/974/
2011-11-16T03:13:22 < karlp> I've spent so much time on the progamming side, effectively zero actually doing anything
2011-11-16T03:13:49 < grummund> heh. yeah
2011-11-16T03:14:07 < BrainDamage> karlp: hey, you managed to get stlink v1 to work decently
2011-11-16T03:14:12 < grummund> problem is trying to find solutions before you realised what the problems are ;)
2011-11-16T03:14:18 < karlp> I am a little bit proud of that BrainDamage :)
2011-11-16T03:14:30 < BrainDamage> that's the opposite of not actually doing anything
2011-11-16T03:14:31 < karlp> grummund: yeah, and I'm really not at the stage to be trying to write generic stm32 libraries
2011-11-16T03:15:10 < karlp> so, I reckon next is getting 802.15.4 interfaced,
2011-11-16T03:16:12 < karlp> must try and ignore remaining inefficiences in stlink code  for now :)
2011-11-16T03:16:37 < grummund> anyway if you need linker script and startup code, i can say it's possible to do just with what ST provided in stdperiph.zip
2011-11-16T03:16:38 < BrainDamage> easy: sed away all the TODO and FIXME :p
2011-11-16T03:17:26  * karlp gigles
2011-11-16T03:17:40 < karlp> grummund: yeah, I need to go through what they provided more carefully, see which bits really do what
2011-11-16T03:18:00 < karlp> I think I'm going to start with trying to get the actual example packages to compile and run again
2011-11-16T03:18:11 < karlp> like, the actual factory demo code for the L1 board
2011-11-16T03:18:32 < grummund> i made a simple blinky if you need it
2011-11-16T03:18:40 < karlp> for l1?
2011-11-16T03:18:50 < karlp> sure, yes please!
2011-11-16T03:19:05 < grummund> well it's for F103
2011-11-16T03:19:14 < karlp> oh, I have those
2011-11-16T03:19:28 < grummund> what's different about L1 then?
2011-11-16T03:19:49 < karlp> it's more like an F2, it has different setups and things,
2011-11-16T03:19:56 < karlp> it shouldn't really be that difficult
2011-11-16T03:20:10 < karlp> I just need to sit down one night and look at _that_ and not _otherstuff_
2011-11-16T03:20:25 < grummund> doesn't stdperiph deal with the differences?
2011-11-16T03:20:49 < karlp> probably, if I look closely enough :)
2011-11-16T03:21:12 < grummund> perhaps i need to get a L board and see
2011-11-16T03:23:51 < karlp> it's groovy
2011-11-16T03:23:59 < karlp> it has a touch slider/buttons, and an LCD :)
2011-11-16T03:24:03 < karlp> you know you wan tone :)
2011-11-16T03:24:09 < karlp> it's actually the one that interested me the most
2011-11-16T03:24:17 < karlp> I'm into low power stuff.
2011-11-16T03:24:28 < grummund> same here
2011-11-16T03:24:46 < karlp> I only got a VL board when I started working on this, and work was sending an order out, so I through one in for a few dollars
2011-11-16T03:24:54 < grummund> is there only the one STM32L1xx board to choose from?
2011-11-16T03:25:02 < karlp> yeah,
2011-11-16T03:25:07 < karlp> well, in the discovery series
2011-11-16T03:25:21 < karlp> who knows in the rest of their development kit lineup
2011-11-16T03:25:36 < karlp> http://www.st.com/internet/evalboard/product/250990.jsp
2011-11-16T03:26:13 < karlp> I got that, and then found out that a) stlink didn't support it, (it was the first stlinkv2 device) and b) that meant I was on serial bootloaders only
2011-11-16T03:26:21 < karlp> so it sat on the shelf for a few months
2011-11-16T03:28:21 < grummund> presumbaly its possible to hook up JTAG
2011-11-16T03:28:50 < karlp> probably
2011-11-16T03:28:55 < karlp> but this was my first arm board
2011-11-16T03:29:02 < karlp> and first board with jtag of any sort
2011-11-16T03:29:30 < karlp> so when I saw, "ultra low power, built in debugger, useable for other devices, bargain price" I snapped it up and decided it was time
2011-11-16T03:30:19 < grummund> so stlink is what exactly?... some windows PC software that hooks up to the secondary IC on that board?
2011-11-16T03:30:31 < BrainDamage> it's an hardware debugger chip
2011-11-16T03:30:51 < BrainDamage> + the software, yes
2011-11-16T03:30:52 < grummund> the chip itself is "stlink"
2011-11-16T03:30:56 < grummund> ?
2011-11-16T03:31:01 < BrainDamage> the firmware in it
2011-11-16T03:31:14 < BrainDamage> the chip is a regular stm32
2011-11-16T03:31:18 < grummund> ok and how does it interface with the stm32
2011-11-16T03:31:31 < grummund> sorry, i've only ever used jtag so far
2011-11-16T03:31:43 < BrainDamage> can use JTAG or SWD for stm32
2011-11-16T03:31:47 < BrainDamage> and SWAG for stm8
2011-11-16T03:32:02 < BrainDamage> the discovery boards use SWD
2011-11-16T03:32:28 < BrainDamage> there's a standalone version of stlink that lets you use all 3
2011-11-16T03:32:47 < grummund> ok, so those SWD pins are for programming a another target board (?)
2011-11-16T03:32:54 < BrainDamage> yes
2011-11-16T03:33:11 < BrainDamage> there's jumpers that let you detach the stlink from the target uC
2011-11-16T03:33:20 < grummund> and the PC interfaces via USB, presumably using "stlink" protocal
2011-11-16T03:33:58 < BrainDamage> yes, the stlink protocol is where the trouble starts
2011-11-16T03:34:30 < BrainDamage> karlp knows this way better than me, but for what I grasped, they hardcoded usb mass storage responses
2011-11-16T03:34:46 < BrainDamage> making it look like a 30 MB flash drive that serves 3 files with few kB
2011-11-16T03:35:09 < BrainDamage> execept the hardcoded responses are wrong and not spec compliant
2011-11-16T03:35:20 < BrainDamage> on windows, it works ok
2011-11-16T03:35:30 < BrainDamage> on linux: it plays quite some bullshit
2011-11-16T03:36:00 < BrainDamage> so you need to actually insert exception in mass storage module to ignore it
2011-11-16T03:36:59 < grummund> i see
2011-11-16T03:37:08 < karlp> stlinkv1 and stlinkv2 are hardware chunks, connected to a host pc via USB, that allow you to to SWD debugging of stm32 targets
2011-11-16T03:37:34 < karlp> on the discovery series of boards, part of the board is an stlink, and part is the "discovery" play part
2011-11-16T03:37:47 < karlp> it's this: http://www.st.com/internet/evalboard/product/219866.jsp
2011-11-16T03:37:51 < karlp> but built onto th eboard
2011-11-16T03:38:09 < karlp> should do jtag too, depends how you wire it I believe
2011-11-16T03:38:17 < BrainDamage> yes
2011-11-16T03:38:33 < BrainDamage> SWD just takes the least amount of wires
2011-11-16T03:38:37 < BrainDamage> that's why they used it :p
2011-11-16T03:38:38 < grummund> i guess SWD is same in concept to dW for Atmel AVR
2011-11-16T03:38:49 < karlp> swd is an arm thing, but yeah, less wires
2011-11-16T03:39:12 < grummund> so what's this firmware you accidentally wiped BrainDamage ?
2011-11-16T03:39:16 < grummund> bootloader?
2011-11-16T03:39:22 < karlp> no, the default factory image
2011-11-16T03:39:31 < BrainDamage> the image in the stm32 target chip
2011-11-16T03:39:34 < BrainDamage> not the st-link
2011-11-16T03:39:42 < karlp> and, because we/me are idiouts, the "example" code in the stlink software package, doesn't actually run
2011-11-16T03:39:49 < karlp> it doesn't include  the startup code,
2011-11-16T03:39:52 < grummund> does SWD rely on that?
2011-11-16T03:40:03 < karlp> so if you had the factory image still on flash, whcih set up vectors and things,
2011-11-16T03:40:09 < karlp> you could load the "example" into sram and run it
2011-11-16T03:40:28 < karlp> but after you burnt anything else at all to flash, the "examples" became very very UN examplish
2011-11-16T03:40:38 < karlp> no permanent damage,
2011-11-16T03:40:47 < karlp> just needed a working image to flash again.
2011-11-16T03:40:59 < karlp> and for me/us to fix the examples to actually be useful
2011-11-16T03:41:17 < BrainDamage> bleh, it turns out my gcc toolchain has a bug :/
2011-11-16T03:41:38 < karlp> you have not had a good week or two with this have you BrainDamage?
2011-11-16T03:42:01 < BrainDamage> well, I didn't give it full attention to be honest
2011-11-16T03:42:03 < grummund> karlp: that should just mean linking with the supplied startup code
2011-11-16T03:42:20 < BrainDamage> but it's been frustrating, yes
2011-11-16T03:42:22 < karlp> it should, yues
2011-11-16T03:42:42 < karlp> but it was only last night I finally got the F4 support merged back together with the F1 support,
2011-11-16T03:42:55 < karlp> I'm now "finished" with the stlink software part, and can play with that sort of thing.
2011-11-16T03:43:28 < BrainDamage> will you ask texane to merge the fork now?
2011-11-16T03:43:36 < BrainDamage> btw, my gcc: 9 aur/cross-arm-none-eabi-gcc 4.6.1-1 [installed] (12)
2011-11-16T03:43:36 < BrainDamage>     The GNU Compiler Collection - Cross compiler for ARM target
2011-11-16T03:43:43 < karlp> oh yeah, so for more confusion, "stlink" is also the name of both a) the st provided utility that talks to this debugger hardware (windows only) and also b) the linux/macosx package that we've been rattling on about for the last few weeks.
2011-11-16T03:43:50 < karlp> BrainDamage: it's merged into texane as of a few hours now
2011-11-16T03:44:06 < grummund> BrainDamage: what was the gcc bug?
2011-11-16T03:44:20 < BrainDamage> it's in the lib
2011-11-16T03:44:53 < BrainDamage> speaking of which, I have a fun fun lib bug in stl
2011-11-16T03:45:25 < BrainDamage> http://codepad.org/noRrMoqn
2011-11-16T03:45:33 < BrainDamage> it's just my unlucky day
2011-11-16T03:45:58 < BrainDamage> that's an unrelated bug, I found yesterday
2011-11-16T03:46:13 < BrainDamage> apparently, libc really hates me
2011-11-16T03:46:29 < grummund> i'm using newlib
2011-11-16T03:46:43 < BrainDamage> that previous was libc on linux
2011-11-16T03:46:59 < BrainDamage> and newlib for the arm, gives me the error I pasted few pages ago
2011-11-16T03:47:03 < BrainDamage> sec
2011-11-16T03:47:29 < BrainDamage> /usr/lib/gcc/arm-none-eabi/4.6.1/../../../../arm-none-eabi/lib/thumb/libc.a(lib_a-syscalls.o): In function `_write':

2011-11-16T03:48:10 < BrainDamage> "it's shit like this" ...
2011-11-16T03:48:33 < karlp> what arm toolchain are you using?
2011-11-16T03:48:42 < BrainDamage> arch's
2011-11-16T03:48:58 < BrainDamage> I'll run summon arm toolchain tomorrow
2011-11-16T03:49:07 < BrainDamage> because I'm out of patience atm
2011-11-16T03:49:13 < BrainDamage> I just have to rant
2011-11-16T03:59:23 < BrainDamage> oh sacred flying spaghetti monster, it's working
2011-11-16T03:59:28 < BrainDamage> it's fucking working
2011-11-16T03:59:49 < BrainDamage> I fixed the bug myself, it was trivial
2011-11-16T04:00:03 < BrainDamage> karlp: thanks for your help and for the stlink software
2011-11-16T04:00:22 < karlp> you're extremely welcome :)
2011-11-16T04:00:29 < karlp> also, congratulations :)
2011-11-16T04:00:33 < jnosky> Brain you cant just change the linker address and expect it to run from flash
2011-11-16T04:00:48 < karlp> so you're using arch linux's built in arm toolchain? and what examples?
2011-11-16T04:01:19 < karlp> also, sweet, the 32l_dac example really works. I can even watch the dac output slowly go up with a multimeter
2011-11-16T04:01:28 < BrainDamage> libopencm3's
2011-11-16T04:01:33 < karlp> excellent
2011-11-16T04:01:41 < karlp> yeah, their VL examples work
2011-11-16T04:01:54 < karlp> so what was wrong?
2011-11-16T04:02:22 < BrainDamage> just an overloaded method
2011-11-16T04:02:43 < BrainDamage> fixed it, compiles fine
2011-11-16T04:03:09 < BrainDamage> now my board is finally flashing like an xmas tree
2011-11-16T04:03:49 < karlp> whee
2011-11-16T04:04:29 < BrainDamage> btw, I'd reiterate the suggestion to temp rename the flash utility to st-flash
2011-11-16T04:04:45 < BrainDamage> at least until you get to finish the unification
2011-11-16T04:05:04 < karlp> I think I'm going to leave it until I just make it an option to st-util.
2011-11-16T04:05:09 < karlp> but, as they say, patches are welcome :)
2011-11-16T04:05:52 < BrainDamage> ok, I guess now that it works, I can actually make that tiny effort
2011-11-16T04:06:06 < BrainDamage> even if to say thanks a bit
2011-11-16T04:07:32 < jnosky> Braindamage are you sating its working from flash now?
2011-11-16T04:07:51 < BrainDamage> yes, but I'm flashing a totally different example
2011-11-16T04:08:03 < karlp> even better! moaaahh working code!
2011-11-16T04:08:17 < karlp> moaaah in the army of functional embedded soldiers!
2011-11-16T04:08:32 < jnosky> At first I thought that changing the linker address would allow ram examples to run from flash
2011-11-16T04:08:40 < jnosky> But thats not the case at all
2011-11-16T04:09:37 < karlp> yeah, apparently we all thought that, or at least, lots of us
2011-11-16T04:09:48 < karlp> we were spectacularly wrong :)
2011-11-16T04:10:08 < jnosky> well that readme makes ya think thats all ya need todo
2011-11-16T04:10:21 < karlp> I'm editing readmes as we speak :)
2011-11-16T04:10:26 < karlp> which one in particular?
2011-11-16T04:10:32 < karlp> the makefile commentary did say that,
2011-11-16T04:10:41 < karlp> I wasn't aware of any readme that said that too?
2011-11-16T04:10:49 < BrainDamage> the makefile in the example
2011-11-16T04:11:04 < BrainDamage> there's one commented section with shifted address
2011-11-16T04:11:35 < BrainDamage> # to run from SRAM
2011-11-16T04:11:35 < BrainDamage> DEF_CFLAGS+=-Wl,-Ttext,0x20000000 -Wl,-e,0x20000000
2011-11-16T04:11:36 < BrainDamage> # to write to flash then run
2011-11-16T04:11:36 < BrainDamage> # DEF_CFLAGS+=-Wl,-Ttext,0x08000000 -Wl,-e,0x08000000
2011-11-16T04:11:37 < karlp> the blink one?
2011-11-16T04:11:41 < BrainDamage> yup
2011-11-16T04:11:41 < grummund> the linker script should take care of locating the code to flash
2011-11-16T04:11:49 < karlp> the blink one is probably the most busted example in the whole tree :(
2011-11-16T04:12:02 < BrainDamage> but that's like busting hello world :/
2011-11-16T04:12:09 < karlp> yeah, tell me about it
2011-11-16T04:12:23 < karlp> that led me down many a dead end. (it wasn't me! honest!)
2011-11-16T04:12:30 < jnosky> The stlink doc pdf
2011-11-16T04:12:49 < BrainDamage> weee, I'm actually already pwing the led
2011-11-16T04:12:51 < jnosky> Ya the linker script takes care of flashing allright
2011-11-16T04:13:35 < jnosky> But what dont tell you is that in order to bring up the blinker you need startupcode, and vectors
2011-11-16T04:14:06 < jnosky> It reads like you just change the target address, and let the good times roll from flash
2011-11-16T04:14:25 < BrainDamage> yeah, I figured this mysef the hard way
2011-11-16T04:14:46 < BrainDamage> esp after I wiped the flash, and noticed the load to ram stopped working as well
2011-11-16T04:15:54 < jnosky> Ya cause there no init code after you did that
2011-11-16T04:16:01 < grummund> there's a snippet of c code you can paste into your main.c to workaround missing startup code
2011-11-16T04:21:11 < jnosky> HooHoo I just a cloned a failing hdd using the "freezer trick" :)
2011-11-16T04:21:19 < karlp> the what?
2011-11-16T04:21:24 < karlp> grummund: what's thsi magic snippet?
2011-11-16T04:22:04 < jnosky> Ya put the hdd in the freezer for a few hours, than ghost or DD it as soon as you take it out
2011-11-16T04:22:26 < grummund> unsigned int * myvectors[4]
2011-11-16T04:22:26 < grummund> __attribute__ ((section("vectors")))= { (unsigned int *)0x20000800,	        // stack pointer (unsigned int *)main,		// code entry point (unsigned int *)nmi_handler,	// NMI handler (not really) (unsigned int *)hardfault_handler	// hard fault handler (let's hope not)
2011-11-16T04:22:27 < jnosky> The theory is that it shrinks some tolerances
2011-11-16T04:22:30 < grummund> };
2011-11-16T04:22:56 < grummund> hmm, sorry that didn't paste well
2011-11-16T04:25:17 < grummund> http://pastebin.com/ugKdccK1
2011-11-16T04:26:15 < jnosky> Oh thats handy, thanks
2011-11-16T04:28:28 < grummund> forgot the declaration for main() - http://pastebin.com/rKUKJnnr
2011-11-16T04:30:10 < jnosky> But you still need a linker script to set vectors addr no?
2011-11-16T04:30:22 < grummund> yes
2011-11-16T04:31:39 < grummund> http://pastebin.com/RUrAu2EW
2011-11-16T04:34:17 < jnosky> Thanks :)
2011-11-16T04:37:05 < grummund> in fact...
2011-11-16T04:37:53 < Thorn> (unsigned int *)main - will this address have 1 added to it?
2011-11-16T04:38:32 < grummund> http://pastebin.com/3wQWyMD2
2011-11-16T04:39:08 < grummund> interesting point Thorn, but it worked so probably yes ;)
2011-11-16T04:39:44 < Thorn> (unsigned int *)0x20000800 -- must not have +1, (unsigned int *)main - must have +1. does it work out?
2011-11-16T04:40:15 < Thorn> I wish this were documented somewhere
2011-11-16T04:41:02 < Tom_itx> it is now
2011-11-16T04:41:23 < Thorn> (otoh, last 2 bits of SP are always 0 so first one isn't critical)
2011-11-16T04:42:26 < grummund> i just re-tested that and the LED is blinking, so yes it works. :)
2011-11-16T04:46:23 < Thorn> Tom_itx: you mean the gcc/ld behavior regarding ARM/Thumb modes and function addresses is documented?
2011-11-16T04:47:03 < grummund> he means he has a bot here recording everything you say
2011-11-16T04:48:57 < Tom_itx> http://www.embeddedrelated.com/usenet/embedded/show/96927-1.php
2011-11-16T04:49:03 < Tom_itx> dunno if that's relevant
2011-11-16T04:50:39 < Tom_itx> still haven't taken mine 'out of the box' yet
2011-11-16T04:52:34 < karlp> lhmm. I wonder what happened to my lcd? the leds are blinking, but the lcd doesn't seem to work with this demo.

2011-11-16T05:04:39 < Thorn> should be usable as a debugger too
2011-11-16T05:04:54 < Thorn> if it works at all lol
2011-11-16T05:05:22 < karlp> is that USB2xxxxx?
2011-11-16T05:05:30 < karlp> somewhat like a buspirate?
2011-11-16T05:05:44 < karlp> but with more transceivers in hardware?
2011-11-16T05:06:11 < karlp> oh yeah, youðve got all the level translators and transceivers on board
2011-11-16T05:06:30 < BrainDamage> u6 & u4 being max 232?
2011-11-16T05:06:40 < Thorn> right
2011-11-16T05:06:51 < karlp> what are you going to do with this creature?
2011-11-16T05:07:07 < Thorn> this chip has 2 independent channels, you can use one for rs-232 and another for jtag for example
2011-11-16T05:08:24 < Thorn> well if I manage to lay it out I'll order PCBs and hope they arrive before the new year holidays (and will work once assembled)
2011-11-16T05:08:58 < Thorn> then I'll sell 1000 of these and get rich of course
2011-11-16T05:10:26 < Tom_itx> what cad package is that?

2011-11-16T05:11:16 < karlp> it's based on that highspeed dual channel usb chip thingy
2011-11-16T05:11:41 < Tom_itx> Thorn have you done much board layout?
2011-11-16T05:12:08 < Thorn> it's going to be the first real one :)
2011-11-16T05:12:20 < Tom_itx> also have you looked at the hammer stuff?
2011-11-16T05:12:51 < Thorn> there's this board with eagle project available http://www.seeedstudio.com/depot/ft2232h-usb-20-hispeed-breakout-board-p-737.html
2011-11-16T05:12:58 < Thorn> what hammer stuff?
2011-11-16T05:13:01 < karlp> the tin can tools hammer?
2011-11-16T05:13:04 < Tom_itx> yes

2011-11-16T05:14:54 < karlp> it's starting to look a little expensive compared to things like this though: http://www.8devices.com/product/3/wi-fi-4-things/specs

2011-11-16T05:23:35 < Tom_itx> maybe i should have taken his offer at the time.
2011-11-16T05:23:41 < BrainDamage> pandaboard is like santa
2011-11-16T05:23:42 < Tom_itx> i could have had one for free
2011-11-16T05:23:49 < Tom_itx> the kit i think
2011-11-16T05:23:52 < BrainDamage> everyone talks about it, nobody has soon one
2011-11-16T05:24:05 < BrainDamage> beaglebone is interesting too

2011-11-16T05:41:22 < Thorn> why aren't there any low cost trace (TPIU) adapters for cortex-m? it appears that a cheap fpga + some ram can do the trick (the data is manchester encoded, 50 or 66 or so MHz)
2011-11-16T05:41:42 < Thorn> the cheapest adapter that can do that is $1700
2011-11-16T05:52:11 < Tom_itx> that's a fairly good size board for a smt design
2011-11-16T05:52:16 < Tom_itx> you can't fit it in that?
2011-11-16T05:56:18 < Thorn> I tried auto placement (without fixing connectors first), it fits components into a ~100x100mm square
2011-11-16T05:56:34 < Tom_itx> auto placement?
2011-11-16T05:56:37 < Tom_itx> with eagle?
2011-11-16T05:56:39 < Thorn> haven't really tried placing manually yet though
2011-11-16T05:56:45 < Thorn> diptrace
2011-11-16T05:56:47 < Tom_itx> oh
2011-11-16T05:56:53 < Tom_itx> i'd never do that
2011-11-16T05:57:02 < Tom_itx> none of them are very efficient at it
2011-11-16T05:57:08 < Tom_itx> or auto routing either
2011-11-16T05:58:48 < Thorn> it does some crazy things but I think it can be used for estimating area to some degree
2011-11-16T05:59:57 < Tom_itx> i used to autoroute just to get an idea then manually route
2011-11-16T06:00:16 < Tom_itx> but i haven't done anything that complicated yet
2011-11-16T06:00:40 < Tom_itx> what's diptrace cost?
2011-11-16T06:00:57 < Thorn> I use a free version
2011-11-16T06:01:06 < Tom_itx> what limitations?
2011-11-16T06:01:28 < Thorn> 1000 pins
2011-11-16T06:02:25 < Thorn> you can't get that from their website though (only a 500 pin free version there)
2011-11-16T06:02:43 < Tom_itx> where then?
2011-11-16T06:02:49 < Tom_itx> student?
2011-11-16T06:06:25 < Thorn> the company is founded by Russians, they gave away a 1000 pin key on some Russian forum years ago, it still works. you have to enter "for non-commercial use" in Russian in the registration dialog using a keyboard (copy/paste doesn't work I believe :) for the key to work
2011-11-16T06:07:17 < Tom_itx> oh
2011-11-16T06:09:17 < Thorn> the tactics seemed to work, no cracks or keygens are available to date :)
2011-11-16T06:11:25 < Thorn> (my project uses 367 pins)

2011-11-16T16:49:51 < jnosky> No ove not seen that problem, i responded with a cupl suggestions
2011-11-16T16:50:07 < jnosky> Ive got a small request tho
2011-11-16T16:50:12 < jnosky> On ugly logger
2011-11-16T16:50:42 < jnosky> Maybe eliminate the date time stamps, to try to fit each entry to 80 chars
2011-11-16T16:51:04 < jnosky> Most terminals are 80 chars, and the logging is well.. ugly :)

2011-11-16T19:01:10 < karlp> sure :)
2011-11-16T19:01:33 < karlp> I've often used the timestamps for watching how long thins are, and correlating two different windws
2011-11-16T19:01:39 < karlp> but it's less useful when you're not in debug
2011-11-16T19:17:42 < jnosky> Well even if they were on a serate line i think it would be better or only for DBG messages maybe
2011-11-16T19:17:58 < jnosky> Im just anal about the format of things on the screen
2011-11-16T19:18:24 < jnosky> It hurts my eyes when info flows onto the next line, I cant just scan down col 0 with my eyes

2011-11-16T20:53:34 < Tom_itx> crap
2011-11-16T20:53:47 < Tom_itx> i should go into the custom's business
2011-11-16T20:54:44 <+Steffanx> That 1@#$%ˆ& expensive board dekar ?
2011-11-16T20:54:54 < dekar> it was the cheap one actually
2011-11-16T20:55:02 < dekar> just $1300
2011-11-16T20:55:16 < dekar> I don't think any cheaper was an option
2011-11-16T20:55:26 < dekar> they simply couldn't handle 10G
2011-11-16T20:56:03 < dekar> looks like a small graphics card :)

2011-11-16T21:20:50 <+Steffanx> Yeah, I could've said "i don't know" too, but 5 minutes sounds better
2011-11-16T21:21:55 -!- You're now known as jpa-
2011-11-16T21:22:40 < Laurenceb_> cant find it in the datasheet
2011-11-16T21:23:41 < jpa-> Laurenceb_: electrical characteristics -> operating conditions -> PLL characteristics -> lock time = 350µs
2011-11-16T21:23:56 < Laurenceb_> ah ok course
2011-11-16T21:24:07 < Laurenceb_> its in the characteristics
2011-11-16T21:24:15 < Laurenceb_> odd
2011-11-16T21:24:28 < Laurenceb_> i sample an io pin at power up and its always zero
2011-11-16T21:24:46 < Laurenceb_> im pretty sure the pin rises faster than that
2011-11-16T21:24:58 < Tom_itx> yeah that sure belongs in electrical characteristics
2011-11-16T21:27:00 < jpa-> faster than what?
2011-11-16T21:27:12 < jpa-> the PLL lock time is a maximum, not a minimum
2011-11-16T21:27:28 < jpa-> it may lock in 1µs if it wants to
2011-11-16T21:27:47 < jpa-> does a delay help?
2011-11-16T21:28:28 < Laurenceb_> oh
2011-11-16T21:28:36 < Laurenceb_> i think so - need to do more tests
2011-11-16T21:28:51 < Laurenceb_> yeah the pin takes a few us to stabilise
2011-11-16T21:28:56 < Tom_itx> there's no flag for it?
2011-11-16T21:29:08 < Laurenceb_> flag for what?
2011-11-16T21:29:17 < Tom_itx> indicating when the pll is locked
2011-11-16T21:29:24 < Laurenceb_> yes
2011-11-16T21:29:39 < Laurenceb_> i use the perif lib code - init with pll at 72mhz, then read the pin
2011-11-16T21:30:01 < Laurenceb_> guess ill have to put a short delay in there
2011-11-16T21:45:35 <+Steffanx> or just a while(!xxxxx) ?

2011-11-17T04:54:38 < Tom_itx> i may have it working
2011-11-17T04:54:41 < Tom_itx> i'm not sure
2011-11-17T04:54:43 < Tom_itx> yet
2011-11-17T04:55:11 < karlp> hehe
2011-11-17T04:55:17 < karlp> that's actually a really vague blog post
2011-11-17T04:55:24 < Tom_itx> i know
2011-11-17T04:55:34 < karlp> but yes, current texane master is the best possible code
2011-11-17T04:55:34 < Tom_itx> but i know him
2011-11-17T04:55:40 < Tom_itx> ok
2011-11-17T04:55:56 < karlp> F4 support, and F1 and L1 support, on both stlinkv1 and stlinkv2 hardware
2011-11-17T04:55:58 < Tom_itx> and summon-arm-toolchain
2011-11-17T04:56:06 < Tom_itx> is what i have
2011-11-17T04:56:08 < karlp> without any of the crazy usb-storage quirks
2011-11-17T04:56:16 < karlp> yep, I'm using summon arm toolchain too
2011-11-17T04:56:38 < Tom_itx> but i have yet to load a blink
2011-11-17T04:57:01 < karlp> yeah, however, <src>/examples/blink is a terribly broken example. :(
2011-11-17T04:57:34 < Tom_itx> stlink example?
2011-11-17T04:57:35  * BrainDamage can vouch for that
2011-11-17T04:58:08 < karlp> if they're targetting the F4, Rious and jnosky vouch for the examples in the F4 directory: https://github.com/texane/stlink/tree/master/example/stm32f4
2011-11-17T04:58:37 < Tom_itx> i think that's what i have
2011-11-17T04:59:33 < Rious> both the discovery_demo and IO example work
2011-11-17T04:59:48 < karlp> ^^^ listen to him, he has an F4 :)
2011-11-17T05:00:17 < Tom_itx> i just loaded the latest stlink.git and it had samples with it
2011-11-17T05:00:21 < Tom_itx> is that it?
2011-11-17T05:02:02 < Rious> yes, example/stm32f4/Projects/
2011-11-17T05:02:34 < Rious> in order to compile the discovery_demo, you'll first need to compile example/stm32f4/STM32F4xx_StdPeriph_Driver/
2011-11-17T05:02:54 < Tom_itx> i think i did that already
2011-11-17T05:03:10 < Tom_itx> i've got a bin file for the demo
2011-11-17T05:04:05 < Tom_itx> does it take a while to load?
2011-11-17T05:04:43 < Tom_itx> i'm getting stuff back like:
2011-11-17T05:04:43 < Tom_itx> 2011-11-16T20:50:21 DEBUG src/stlink-common.c: *** stlink_read_mem32 ***

2011-11-17T05:07:08 < karlp> it's about 1k/sec, so not super super fast
2011-11-17T05:08:05 < Tom_itx> ok
2011-11-17T05:08:21 < Tom_itx> i'm spoiled i guess
2011-11-17T05:08:39 < Tom_itx> that code seems to flash the leds slower than the original
2011-11-17T05:09:15 < karlp> if it's still running in the gdb, I do agree that some of the gdb status reporting seems to slow things down
2011-11-17T05:09:29 < Tom_itx> this is all new to me
2011-11-17T05:09:31 < karlp> quitting and power cycling seems to go back to normal
2011-11-17T05:09:35 < karlp> new to me too :)
2011-11-17T05:09:51 < Tom_itx> i unplugged it and tried it again
2011-11-17T05:09:54 < Tom_itx> same
2011-11-17T05:10:04 < karlp> there's definitely something wrong with the way stlink disconnects, it doesn't always seem to leave things in predictable states
2011-11-17T05:10:10 < Tom_itx> i'm used to avr etc
2011-11-17T05:10:21 < Tom_itx> how do you cleanly close the listen window?
2011-11-17T05:10:32 < Tom_itx> i'm using 3 terminals
2011-11-17T05:10:51 < Rious> Tom_itx: I think the discovery_demo code does make the lights flash more slowly
2011-11-17T05:11:13 < Tom_itx> ok well it must be working then
2011-11-17T05:11:37 < Tom_itx> i was using the ubuntu from the emc live cd install so i was missing a shit load of stuff
2011-11-17T05:12:21 < BrainDamage> why would you develop on a hard realtime machine?
2011-11-17T05:12:49 < Tom_itx> it's the only linux box i've got beside my server which has no keyboard or monitor on it
2011-11-17T05:13:30 < Tom_itx> i've got iar on windows installed
2011-11-17T05:13:46 < Tom_itx> just to try that as well
2011-11-17T05:14:31 < Tom_itx> i'm not real sure what i'm gonna do with this anyway
2011-11-17T05:14:59 < Tom_itx> just depends if i fall in love with arm or not i suppsoe
2011-11-17T05:15:00 < Tom_itx> suppose
2011-11-17T05:15:26 < karlp> well, yeah, there's sure no avr-libc yet :)
2011-11-17T05:16:01 < Tom_itx> the have some lib stuff with the examples but i haven't looked at em yet
2011-11-17T05:16:07 < Tom_itx> not sure what those are
2011-11-17T05:19:42 < Tom_itx> what's the IO_Toggle demo do?
2011-11-17T05:24:06 < Tom_itx> the original demo runs normal
2011-11-17T05:24:06 < Tom_itx> i just loaded it
2011-11-17T05:24:18 < Tom_itx> wonder why his is slower

2011-11-17T05:28:51 < karlp> no clue,
2011-11-17T05:28:55 < karlp> time for bed :)

2011-11-17T12:56:10 < Laurenceb> does the EXTI have to have a certain slew rate to trigger?
2011-11-17T12:56:28 < jpa-> doubtful
2011-11-17T13:15:18 < Laurenceb> hmm
2011-11-17T13:15:25 < Laurenceb> its not triggering
2011-11-17T13:21:06 <+Steffanx> pebkac :P
2011-11-17T13:25:34 < Laurenceb> im using 5v on the pin
2011-11-17T13:25:40 < Laurenceb> dont know if that changes anything
2011-11-17T13:30:06 < Laurenceb> hmm B2 is 5v tolerant
2011-11-17T13:30:10 < Laurenceb> this makes no sense

2011-11-17T13:35:36 < Laurenceb> exti2 wont trigger, yet it is enabled
2011-11-17T13:35:41 < Laurenceb> i can check with jtag
2011-11-17T13:43:10 < Laurenceb> reading the gpio works
2011-11-17T13:43:32 < Laurenceb> and exti0 works
2011-11-17T13:44:50 <+Steffanx> And the pin is set as input etc?

2011-11-17T21:41:40 < jnosky> The only thing I can find is the discovery demo
2011-11-17T21:41:50 < BrainDamage> checked the one in libopencm3?

2011-11-17T21:43:06 <+Steffanx> Should be it ?
2011-11-17T21:43:14 < jnosky> ^That one has zero examples for usb !
2011-11-17T21:43:17 <+Steffanx> oh, usb
2011-11-17T21:43:37 <+Steffanx> nvm :)
2011-11-17T21:43:44 < jnosky> Think the libopencm3 might support f4?
2011-11-17T21:43:50 < BrainDamage> it does
2011-11-17T21:43:56 < jnosky> Thanks any steff
2011-11-17T21:44:00 < jnosky> way
2011-11-17T21:44:06 < BrainDamage>   - ST STM32F1 series  - ST STM32F2 series  - ST STM32F4 series
2011-11-17T21:44:56 <+Steffanx> The stm32F1/2 usb examples don't work for the f4?
2011-11-17T21:45:09 < jnosky> Well I think they wont
2011-11-17T21:45:20 < jnosky> All the includes etc are for f1
2011-11-17T21:45:30 < jnosky> Lots of conditional code for f1 devices
2011-11-17T21:45:41 < jnosky> And not linked against f4 lib
2011-11-17T21:46:10 < jnosky> Judging by all the issues getting stlink to run on f4.....
2011-11-17T21:46:45 < jnosky> I think its bizzare they (stm) dont give any examples, they give examples for every other peripheral
2011-11-17T21:46:53 <+Steffanx> You're on linux?
2011-11-17T21:48:09 < jnosky> Well I built all the stuff with cygwin, and did all the f4 mods for stlink so I could dev under eclipse/win
2011-11-17T21:49:25 <+Steffanx> You could have used the stuff from TruStudio too (I did that for my stm32f1-dev)
2011-11-17T21:49:35 <+Steffanx> *TrueStudio
2011-11-17T21:50:25 < jnosky> I no longer have problems building for the f4
2011-11-17T21:50:32 < jnosky> Ive just got nuthing to build
2011-11-17T21:51:15 <+Steffanx> Hmm, the stm32f1 usb example should sort of work on the stm32f4
2011-11-17T21:51:57 <+Steffanx> They state the usb stuff of the F2 is fully compatible with the F1
2011-11-17T21:52:10 <+Steffanx> They also claim the f4 is software compatible with the f2
2011-11-17T21:52:19 <+Steffanx> So F4 = F1 ?
2011-11-17T21:54:00 < jnosky> Oh it is?

2011-11-17T22:17:47 <+Steffanx> I think anyone here has a f103 setup, i sjust don't know who :)
2011-11-17T22:18:52 < Laurenceb_> was wondering if anyone could make EXTI2 trigger off B.2
2011-11-17T22:18:55 <+Steffanx> izua and dekar have a f103 board iirc, but they are not here :)
2011-11-17T22:20:32 < Laurenceb_> im pretty sure it wont work for me
2011-11-17T22:20:48 < Laurenceb_> if i change the gpio and exti config to another port it works
2011-11-17T22:21:17 < Laurenceb_> portb,pin2 is the BOOT1 pin, im not sure if that matters
2011-11-17T22:21:23 < Laurenceb_> i can use gpio ok

2011-11-17T22:40:29 < Laurenceb_> that means i had ~5V on B.2 with 0v on VDD
2011-11-17T22:40:45 < Laurenceb_> absolute max on 5v tolerant pins is VDD+4V
2011-11-17T22:41:00 < Laurenceb_> maybe that damaged the pin
2011-11-17T22:43:30 < Laurenceb_> ill have to poll it from the main loop for the time being
2011-11-17T22:43:38 < Thorn> I'd think it wouldn't work at all if damaged
2011-11-17T22:43:59 < Laurenceb_> you didnt do any weird config stuff did you?
2011-11-17T22:44:06 < Laurenceb_> just set the pin as input floating?
2011-11-17T22:44:15 < Thorn> I set it as IPU

2011-11-17T22:44:35 < Thorn> since the triger is set to falling edge
2011-11-17T22:45:23 < Laurenceb_> yeah
2011-11-17T22:45:38 < Laurenceb_> hmm i can only think its a hardware failure
2011-11-17T22:46:08 < Laurenceb_> and i probably exceeded absolute max on that pin by plugging in usb with no battery connected
2011-11-17T22:47:26 < Laurenceb_> which shouldnt have happened - too many things wrong on my pcb
2011-11-17T22:47:46 < Laurenceb_> anyway, thanks for the help
2011-11-17T22:49:13 < Thorn> try measuring resistance from that pin to vcc and gnd or something
2011-11-17T22:49:46 < Laurenceb_> yeah ok
2011-11-17T22:49:50 < Thorn> if it works as a normal gpio but not as an EXTI source it's strange
2011-11-17T22:50:13 < Laurenceb_> well ive hacked a resistor between it and USB now
2011-11-17T22:50:23 < Laurenceb_> and it goes to 5V and 0v
2011-11-17T22:53:14 < Laurenceb_> through 10K
2011-11-17T23:06:05 < Laurenceb_> are there any USB examples for the stm32f1 anywhere?
2011-11-17T23:06:49 < Thorn> there're some appnotes

2011-11-17T23:07:59 < Laurenceb_> yeah i want to impliment mass storage
2011-11-17T23:08:05 < Laurenceb_> should probably just google
2011-11-17T23:08:08 < Thorn> there's an audio player demo for f4

2011-11-18T00:12:29 < whitequark> is there a not braindead libc for stm32's? the one I've seen (something recommended by ST) was bloated beyond any reason and looked like it was written by bad unix developer in late 80's
2011-11-18T00:13:01 < whitequark> google says there are newlib and libopenstm32. If someone has used any of them, I'd like to hear about experience
2011-11-18T00:13:55 < Thorn> newlib is included with codesourcery
2011-11-18T00:14:16 < Thorn> I used strcmp from it :)
2011-11-18T00:14:54 < whitequark> I have written my own. It's quite painful to define a register and miss a field or misplace a bit, through
2011-11-18T00:15:06 < Thorn> there're also some very lightweight implementations of printf() that don't use mlalloc() out there
2011-11-18T00:15:41 < Laurenceb_> ive got one on my github

2011-11-18T00:20:10 < BrainDamage> whitequark: libstm32 is now called libopencm3

2011-11-18T00:20:55 < BrainDamage> ah
2011-11-18T00:21:52 < BrainDamage> you might want a different name then :p
2011-11-18T00:22:22 < Laurenceb_> my printf suffers some classic errors in float print XD
2011-11-18T00:22:26 < whitequark> BrainDamage: I'd rather ditch it completely. I don't have resources to maintain a libc
2011-11-18T00:22:33 < Laurenceb_> 0.3 is 0.2999999999999999999
2011-11-18T00:22:57 < Laurenceb_> but way smaller than standard printf
2011-11-18T00:23:00 < whitequark> Laurenceb_: that's not an error (nor the bug) in the printf.
2011-11-18T00:23:39 < Laurenceb_> well there are techniques ot stop that happening
2011-11-18T00:23:46 < Laurenceb_> but i didnt bother XD
2011-11-18T00:24:47 < Laurenceb_> try on your pc with gcc and you wont see reoccurring 9
2011-11-18T00:25:00 < whitequark> they're doing it wrong. FPU isn't guilty of people prefering some random "round" numbers, and thankfully it doesn't even know about decimal arithmetics.
2011-11-18T00:25:17 < Laurenceb_> i know
2011-11-18T00:25:25 < whitequark> And if glibc displays 0.3 instead, they may hide some serious bugs.
2011-11-18T00:25:43 < Laurenceb_> for sane purposes of noisy data that error is irrelevant
2011-11-18T00:26:00 < whitequark> ok...
2011-11-18T00:26:26 < whitequark> then don't ask why in some comparsion 0.3 is not equal to 0.3 or whatever.
2011-11-18T00:26:38 < whitequark> the rounding should be explicit.
2011-11-18T00:26:49 < Laurenceb_> heh feel free to offer a correction XD
2011-11-18T00:27:37 < whitequark> glibc does not even considers most bugs as requiring a fix. do you think they'll listen to me?
2011-11-18T00:27:50 < whitequark> * glibc maintainers does not even consider
2011-11-18T00:29:38 < whitequark> hm, I like the overall look of libopencm3
2011-11-18T00:30:02 < whitequark> but I wonder why they don't inline one-liners
2011-11-18T00:30:16 < whitequark> does gcc do that?
2011-11-18T00:33:40 < Laurenceb_> sorry i thought you were talking about my printf

2011-11-18T18:15:52 < karlp> dekar_: do you know if there's some mechanism like modprobe black lists that would let steffanx turn off usb-storage for a certain vid/pid?
2011-11-18T18:16:20 < karlp> Steffanx: the old code used to have a delay of 5-7 seconds, to allow time for the OS to detach the usb-storage drivers before reattaching
2011-11-18T18:16:52 < karlp> on linux, as we don't use usb-storage for stlinkv1 anymore, there's just a modprobe rule to disable mass-storage, so the device can be detached and reattached immediately
2011-11-18T18:17:04 < karlp> it may be that on osx, the wait needs to be there?
2011-11-18T18:27:02 < Laurenceb> usbd_msc_core.h
2011-11-18T18:27:10 < Laurenceb> ^any idea where that should be?
2011-11-18T18:59:08 < grummund> Laurenceb: which project is that from and which mcu do you have?#
2011-11-18T19:16:24 < Laurenceb> ST example
2011-11-18T19:16:37 < Laurenceb> ive got it now - they wrote a new USB library
2011-11-18T19:32:00 <+Steffanx> karlp there's a method do unload a driver, but that doesn't seem to work for mass storage
2011-11-18T19:32:23 <+Steffanx> And i don't want to 'permanently' disable it
2011-11-18T19:32:58 < grummund> Laurenceb: which example?  i'm playing with USB on F103 mcu, just so curious...
2011-11-18T19:33:25 < Laurenceb> http://www.st.com/internet/com/SOFTWARE_RESOURCES/SW_COMPONENT/FIRMWARE/stm32_f105-07_f2xx_usb-host-device_lib.zip
2011-11-18T19:35:22 < grummund> ok, explains why i don't have that file
2011-11-18T19:37:49 < karlp> Steffanx: you probably want to permanently disable mass storage for the stlink v1 usb VID and PID
2011-11-18T19:38:04 < karlp> unless you _realllly_ want to see that drive pop up with the three url shortcuts on it.
2011-11-18T19:38:29 <+Steffanx> I don't see that karlp :)
2011-11-18T19:38:42 <+Steffanx> os x doesn't really understands what do with it
2011-11-18T19:38:44 < karlp> well, that's the only reason you would want usb-storage enabled for the stlink v1 pid
2011-11-18T19:38:45 <+Steffanx> *knows
2011-11-18T19:38:59 <+Steffanx> I don't know if and how you disable it for a single device
2011-11-18T19:39:02 < karlp> and letting OSX even try and work out what to do with it is just unproductive :)
2011-11-18T19:39:08 < karlp> yeah, ask Rious  and jnosky  :)
2011-11-18T19:39:15 < karlp> I don't know either :)

2011-11-19T14:15:24 < grummund> i've been doing some reading on embedded linux and arrived at the conclusion that "elf" vs. "eabi" debate is only relevant for targeting a system with Linux.
2011-11-19T14:15:55 < jpa-> "elf" is a horrible way to define an ABI
2011-11-19T14:15:58 < grummund> for bare metal hardware "elf" vs. "eabi" is irrelevant, it seems.
2011-11-19T14:16:15 < jpa-> "eabi" is atleast a standard :)
2011-11-19T14:16:46 < grummund> hmm, well i'm using elf and it works...
2011-11-19T14:17:36 < grummund> does it not all arrive at the same binary once linked/stripped and flashed to the device?
2011-11-19T14:18:31 < jpa-> not necessarily
2011-11-19T14:18:37 < jpa-> eabi defines some stack alignment rules
2011-11-19T14:18:50 < jpa-> but it all only matters if you want to use some pre-compiled libraries
2011-11-19T14:19:20 < grummund> yes.  e.g. with an OS
2011-11-19T14:20:25 < grummund> for a project compiled all from source and to a single binary blob, it makes no difference, right?

2011-11-19T21:26:09 < Xunil> everything works except gdb, which wants ncurses, yada yada... turns into a pain in the neck.
2011-11-19T21:26:29 < Xunil> i'm trying to port a Forth implementation - Riscy Pygness - to the STM32F4 Discovery board.
2011-11-19T21:26:35 < jpa-> if you need just gdb, it shouldn't be much work to compile
2011-11-19T21:26:39 < BrainDamage> I've built it myself no problem
2011-11-19T21:27:00 < BrainDamage> but it's shared linked, I hightly doubt it'll work for you
2011-11-19T21:27:06 < Xunil> nod, ok
2011-11-19T21:27:11 < BrainDamage> unless you got arch as well, and a recent set of libs
2011-11-19T21:27:14 < Xunil> i'll just build it... not that big of a deal, as yous ay
2011-11-19T21:30:23 < Laurenceb_> argggg
2011-11-19T21:30:30 < Laurenceb_> why is USB so complex
2011-11-19T21:30:57 < jpa-> so that it would fit in a nutshell
2011-11-19T21:31:06 < Laurenceb_> lol
2011-11-19T21:31:19 < Laurenceb_> who suggested i use UM0424 yesterday?
2011-11-19T21:35:45 < jpa-> grummund: 
2011-11-19T21:43:15 < Laurenceb_> oh yeah
2011-11-19T21:49:02 < whitequark> BrainDamage: LD_LIBRARY_PATH works just fine if applied wisely
2011-11-19T21:49:56 < BrainDamage> but I'd have to send him my libc
2011-11-19T21:50:07 < BrainDamage> and whatever else it uses
2011-11-19T22:09:33 < Laurenceb_>  -I/<folder> should allow me to #include files from that folder right?
2011-11-19T22:10:39 < jpa-> yes
2011-11-19T22:11:47 < Tom_itx> Laurenceb bluetooth is worse than usb
2011-11-19T22:12:38 < Tom_itx> i've heard LUFA has been ported to ARM but i don't know where the work is
2011-11-19T22:13:35 < Tom_itx> http://www.fourwalledcubicle.com/LUFA.php
2011-11-19T22:13:41 < Tom_itx> is the AVR original version
2011-11-19T22:14:02 <+Steffanx> nxp Tom_itx
2011-11-19T22:14:35 < Tom_itx> commercial or other?
2011-11-19T22:14:58 <+Steffanx> The LUFA port you're talkign about
2011-11-19T22:15:14 < Tom_itx> ok, i wasn't sure
2011-11-19T22:15:30 <+Steffanx> nxlpUSBlib
2011-11-19T22:15:33 <+Steffanx> -l
2011-11-19T22:15:45 < Tom_itx> are ARM variants completely different in reg structure?
2011-11-19T22:16:06 <+Steffanx> You're not allowed to port the nxpUSBLib to another arm
2011-11-19T22:16:13 <+Steffanx> iirc
2011-11-19T22:16:47 < Laurenceb_> im trying to compile um4024
2011-11-19T22:16:51 < Tom_itx> would that be like... criminal.. like sending samples to someone?
2011-11-19T22:17:11 <+Steffanx> It's not criminal .. they probably paid Dean to get such a license Tom_itx
2011-11-19T22:17:22 < Tom_itx> i'm sure
2011-11-19T22:17:33 < Tom_itx> then they're not that willing to share the source
2011-11-19T22:17:55 <+Steffanx> The source is open, you can't use it on non-nxp ARM's
2011-11-19T22:18:12 < Tom_itx> doesn't sound so open to me then
2011-11-19T22:18:30 < jpa-> indeed
2011-11-19T22:18:44 < Tom_itx> lunch. bbl
2011-11-19T22:19:37 < Laurenceb_> ther conf file has gone
2011-11-19T22:19:46 < Laurenceb_> i dont understand
2011-11-19T22:19:57 < Laurenceb_> : error: 'GPIO_InitTypeDef' undeclared
2011-11-19T22:20:17 < Laurenceb_> presumably as i need to include gpio support in the perif conf file
2011-11-19T22:20:21 < Laurenceb_> but there isnt one
2011-11-19T22:20:22 < Laurenceb_> wtf
2011-11-19T22:20:55 < Laurenceb_> has anyone tried to compile um0424?
2011-11-19T22:23:52 < Laurenceb_> omg this is horrific
2011-11-19T22:24:10 < Laurenceb_> has anyone actually tried to make a sane USB mass storage device yet?
2011-11-19T22:29:45 < grummund> it built for me but i dodn't try testing it
2011-11-19T22:29:55 < grummund> CDC usb-serial worked though
2011-11-19T22:30:20 < Laurenceb_> with gcc?
2011-11-19T22:30:28 < Laurenceb_> do you have your makefile pls?
2011-11-19T22:31:16 < Laurenceb_> did you write one from scratch?
2011-11-19T22:31:27 < Laurenceb_> im trying to write one atm but the linking is all weird
2011-11-19T22:31:30 < grummund> what toolchain do you have?
2011-11-19T22:31:35 < Laurenceb_> relative to my other projects
2011-11-19T22:31:39 < Laurenceb_> codesourcery g++
2011-11-19T22:31:58 < grummund> ok, does that make an elf file or what?
2011-11-19T22:32:13 < grummund> i mean how does it arrive at the final binary to be flashed to the device?
2011-11-19T22:32:15 < Laurenceb_> yes
2011-11-19T22:32:22 < Laurenceb_> elf yes
2011-11-19T22:32:41 < Laurenceb_> did you make a makefile?
2011-11-19T22:32:59 < grummund> so you build an elf file and use objcopy to extract the binary image to be flashed?
2011-11-19T22:33:06 < Laurenceb_> hopefully yes
2011-11-19T22:33:10 < Laurenceb_> atm i cant compile
2011-11-19T22:33:15 < Laurenceb_> as i need a makefile
2011-11-19T22:33:26 < grummund> sure but i need to understand your toolchain
2011-11-19T22:33:38 < Laurenceb_> its basically plain gcc
2011-11-19T22:33:43 < grummund> it makes an elf file though?
2011-11-19T22:33:49 < Laurenceb_> just vanilla gcc with some patches
2011-11-19T22:33:51 < Laurenceb_>  yes
2011-11-19T22:33:56 < Laurenceb_> on ubuntu
2011-11-19T22:34:09 < grummund> and then use objcopy to derive a .bin file
2011-11-19T22:34:13 < Laurenceb_> yeah
2011-11-19T22:34:21 < Laurenceb_> but i can handle all that
2011-11-19T22:34:34 < Laurenceb_> its the includes and startup file and things thats confusing me
2011-11-19T22:34:50 < grummund> what is the toolchain prefix?
2011-11-19T22:34:58 < Laurenceb_> looks like it will only work if i compile usb and perif as seperate libraries then link to them
2011-11-19T22:35:03 < grummund> arm-eabi-none-* or what?
2011-11-19T22:35:11 < Laurenceb_> just a sec ill link my makefile - its broken
2011-11-19T22:35:41 < Laurenceb_> http://pastebin.com/YwKvCAsX
2011-11-19T22:36:23 < Laurenceb_> atm i get src/fsmc_nand.c:43:3: error: 'GPIO_InitTypeDef' undeclared
2011-11-19T22:36:33 < Laurenceb_> as its not seeing the gpio headers
2011-11-19T22:36:47 < Laurenceb_> evcen tho they are included from the conf file in ./inc
2011-11-19T22:37:04 < Laurenceb_> maybe i need to define a target board or something
2011-11-19T22:37:10 < Laurenceb_> and its not my makefile
2011-11-19T22:37:43 < grummund> try that - http://pastebin.com/EHwpnZK2
2011-11-19T22:38:46 < Laurenceb_> eeeek
2011-11-19T22:38:52 < Laurenceb_> did you use a tool for that?!
2011-11-19T22:39:03 < grummund> no
2011-11-19T22:39:29 < grummund> rm -rf STM32_USB-FS-Device_Lib_V3.3.0
2011-11-19T22:39:34 < grummund> unzip -q um0424.zip
2011-11-19T22:39:40 < grummund> P=Mass_Storage; make -f $(pwd)/Makefile.$P -C STM32_USB-FS-Device_Lib_V3.3.0/Project/$P
2011-11-19T22:40:21 < grummund> save that pastebin as Makefile.Mass_Storage and then run the above
2011-11-19T22:48:00 < Laurenceb_> bbl cooking
2011-11-19T22:52:21 < grummund> thanks?
2011-11-19T22:54:45 <+Steffanx> He cooks for you grummund
2011-11-19T22:56:04 < grummund> ah
2011-11-19T23:01:07 < Laurenceb_> heh i sould if i could
2011-11-19T23:01:12 < Laurenceb_> yeah it works
2011-11-19T23:01:18 < Laurenceb_> amazing, thanks XD
2011-11-19T23:02:54 < Laurenceb_> all the linking makes my brain hurt :P
2011-11-19T23:03:12 < grummund> let's hope it runs :p
2011-11-19T23:03:20 < Laurenceb_> heh dont have the hardware here
2011-11-19T23:03:28 < Laurenceb_> i was just using the eval board file
2011-11-19T23:03:51 < Laurenceb_> will have to rewrite it to work with my hardware, but at least i can make it compile now
2011-11-19T23:04:42 < Laurenceb_> ultimately i want to swap the ST spi<->SD code for the FatFS code
2011-11-19T23:04:49 < Laurenceb_> as that uses DMA
2011-11-19T23:10:19 < Laurenceb_> ok, thanks - bbl
2011-11-19T23:11:17 < grummund> Laurenceb_: can you do me a favour?
2011-11-19T23:11:17 <+Steffanx> Have a nice diner

2011-11-19T23:40:45 < Tom_itx> mmm the reference manual must be the main one
2011-11-19T23:40:47 < Tom_itx> it's 13M
2011-11-19T23:41:59 < grummund> if it's anything like the F103 there are 3 main docs you need
2011-11-19T23:42:54 < grummund> datasheet, programmers manual, reference manual.
2011-11-19T23:43:06 < grummund> oh, and firmware manual (stdperiph).
2011-11-19T23:43:36 < Tom_itx> i think i found them
2011-11-19T23:43:43 < Tom_itx> which one has the registers in it?
2011-11-19T23:43:51 < Tom_itx> is there a register summary like avr has?
2011-11-19T23:45:28 < grummund> generally the RM
2011-11-19T23:46:18 < grummund> although you may find it easier to use their firmware library (stdperiph)
2011-11-19T23:46:26 < grummund> than direct register access
2011-11-19T23:48:16 < Tom_itx> i was looking at those a bit

2011-11-20T00:47:47 < TechIsCool> I am back still have the same question. How do I figure out timing on the stm32f4 discovery I can't seem to get it to work correctly
2011-11-20T00:56:23 < grummund> can you get 100ms systick to work?
2011-11-20T00:57:03 < TechIsCool> I have no scope so I can't confirm when I set the tick to supposibly 10ms and then multiple buy 100 to get a second it seems like it is running slow by maybe 300ms
2011-11-20T00:57:36 < TechIsCool> here is what I am setting it as 	  if (SysTick_Config(SystemCoreClock / 100)) 	  { 	    /* Capture error */ 	    while (1); 	  }
2011-11-20T00:58:05 < TechIsCool> uint32_t SystemCoreClock = 168000000;
2011-11-20T01:03:50 < TechIsCool> all I really am trying to get out of the clock is 10us interrupt but could not figure it out and since I have no scope its easier to work in longer times and then go smaller
2011-11-20T01:04:15 < Laurenceb_> grummond: ok just a sec
2011-11-20T01:04:21 < Laurenceb_> was away sorry
2011-11-20T01:05:48 < TechIsCool> well welcome back
2011-11-20T01:12:22 < Laurenceb_> http://pastebin.com/G0rrd3t6
2011-11-20T01:12:34 < Laurenceb_> lots of Q.. odd
2011-11-20T01:12:43 < TechIsCool> what is that
2011-11-20T01:12:44 < TechIsCool> lol
2011-11-20T01:12:48 < TechIsCool> sorry noob
2011-11-20T01:13:25 < TechIsCool> actually all of my Q's are lower case not sure the difference
2011-11-20T01:13:44 < grummund> Laurenceb_: thanks.  and arm-none-eabi-gcc --version ?
2011-11-20T01:14:10 < Laurenceb_> 4.5.2
2011-11-20T01:14:19 < Laurenceb_> from codesourcery - latest version
2011-11-20T01:14:24 < Laurenceb_> why?
2011-11-20T01:14:36 < grummund> my gcc is buggy i think
2011-11-20T01:14:49 < grummund> that output is the ISR vector table
2011-11-20T01:15:00 < grummund> mine needed hacking to work but yours is ok
2011-11-20T01:15:01 < Laurenceb_> hmm - vanilla gcc?
2011-11-20T01:15:10 < grummund> same source code, same makefile.
2011-11-20T01:15:17 < Laurenceb_> yeah i just grabbed the binary from mentor graphics
2011-11-20T01:15:35 < Laurenceb_> hardware is at work so i cant test
2011-11-20T01:15:46 < grummund> 4.5.2 here too
2011-11-20T01:15:59 < Laurenceb_> im going to chill out and watch some tv, its saturday night ffs  XD
2011-11-20T01:16:06 < grummund> g'night
2011-11-20T01:17:02 < TechIsCool> hey grummund  can you help me?
2011-11-20T01:17:55 < grummund> if it's quick... i'm off soon.
2011-11-20T01:18:23 < TechIsCool> alright how do I get a 1us interupt on the systemtick
2011-11-20T01:18:45 < grummund> that's blindingly fast, why do you want to do that?
2011-11-20T01:19:08 < TechIsCool> well I am trying to use it as a delay and I need microseconds
2011-11-20T01:19:21 < TechIsCool> should I be using a TIM?
2011-11-20T01:19:29 < grummund> ah... wel don't :P
2011-11-20T01:20:02 < grummund> For uS delay probably use a timed loop, but maybe ST have something in the library already.
2011-11-20T01:20:26 < TechIsCool> that's what I thought but I have yet to come across anything like it
2011-11-20T01:23:14 < grummund> the compiler generates a shit load of code even for an empty interrupt handler, and you want to run that a million times per second? :P
2011-11-20T01:24:09 < TechIsCool> all I am trying to do is turn a general i/o on for 10uS and then off
2011-11-20T01:25:59 < grummund> continuously?
2011-11-20T01:26:11 < TechIsCool> no
2011-11-20T01:26:34 < TechIsCool>    GPIO_WriteBit(GPIOE, GPIO_Pin_4, 0);    delayMicroseconds(2); //Output should be ~ 20uS long    GPIO_WriteBit(GPIOE, GPIO_Pin_4, 1);    delayMicroseconds(1);  //Output should be ~ 10uS long    GPIO_WriteBit(GPIOE, GPIO_Pin_4, 0);
2011-11-20T01:27:03 < grummund> what's this... high speed morse code? :P
2011-11-20T01:27:44 < TechIsCool> nope its for driving a GE led light string
2011-11-20T01:27:45 < TechIsCool> http://pastebin.com/Ek2vFWqJ
2011-11-20T01:28:02 < grummund> anyway, you might look at timers... (not systick though), and don't expect to generate 1us interrupts for counting.
2011-11-20T01:28:15 < TechIsCool> alright thanks for the help
2011-11-20T01:28:31 < grummund> right, i'm off... bye.

2011-11-20T20:15:49 <+Steffanx> Yeah, izua is 'last seen' 3 weeks ago
2011-11-20T20:16:35 < Thorn> I did the layout for my pcb http://imgur.com/a/ZoegE
2011-11-20T20:17:14 <+Steffanx> What is it?
2011-11-20T20:17:33 < Thorn> Universal Serial Interface(tm)
2011-11-20T20:18:29 <+Steffanx> Just curious, why you waste so 'much' energy @ D6 and D8 :)
2011-11-20T20:18:38 <+Steffanx> Can't you use 3.3V for those led's too?
2011-11-20T20:20:03 < Thorn> TXCAN/RXCAN lines are 5V and I've no idea how these transistors will like having base above collector
2011-11-20T20:20:28 <+Steffanx> Oh
2011-11-20T20:20:36 < Thorn> if it's ever going to be above collector that is...
2011-11-20T20:21:10 < Thorn> oh wait it will
2011-11-20T20:21:22 <+Steffanx> And no protection on the USB data lines?
2011-11-20T20:22:13 <+Steffanx> And non-45 degrees lines are ugly imho .. but that's just my opinion :P
2011-11-20T20:23:25 < Tom_itx> oh lord
2011-11-20T20:23:35 <+Steffanx> Where?
2011-11-20T20:23:45 < Tom_itx> Steffanx straighten that guy out would ya?
2011-11-20T20:23:53 <+Steffanx> Time to go to church Tom_itx ?
2011-11-20T20:25:29 < jpa-> Thorn: a NPN transistor will never have base over 0.7V
2011-11-20T20:25:42 <+Steffanx> I could never make a PCB with non-45 degree angles
2011-11-20T20:26:01 <+Steffanx> Is that called perfectionism ?
2011-11-20T20:26:25 < Thorn> this thing is usb 2.0, I don't know what protection is available (and I want this board to arrive before the end of the year when the postal service is overloaded)
2011-11-20T20:26:42 <+Steffanx> Ask Tom_itx about that
2011-11-20T20:26:55 <+Steffanx> I never made a usb board WITH projection. He did
2011-11-20T20:27:31 <+Steffanx> Going to order it from seeed Thorn ?
2011-11-20T20:27:40 < Thorn> yes
2011-11-20T20:28:56 <+Steffanx> What did you use to draw this Thorn ? KiCAD?
2011-11-20T20:28:57 < Thorn> so I'm sorry but no time to make the traces pretty :)
2011-11-20T20:29:02 < Thorn> diptrace
2011-11-20T20:29:05 <+Steffanx> Hmm
2011-11-20T20:29:35 <+Steffanx> I sort of like Diptrace but it lacks so many standard components
2011-11-20T20:30:08 < Thorn> I had to make components for almost everything, hopefully no errors there
2011-11-20T20:30:45 <+Steffanx> The 3D view is nice, but the components from 3dcentralsomething never work
2011-11-20T20:31:02 <+Steffanx> 3dcontentcentral.com :)
2011-11-20T20:33:06 < Thorn> looks like I can delete the 5v trace to those leds and connect them to the 3.3V bus instead (and add a decoupling cap for the rs-485 IC and fix a couple other mistakes too...)
2011-11-20T20:33:26 <+Steffanx> :)
2011-11-20T20:34:12 < Thorn> btw, what about the top layer pour? bottom layer will be poured with ground but all the development boards that I own have top layer poured too
2011-11-20T20:34:32 <+Steffanx> Don't ask me about that :P
2011-11-20T20:34:34 < Thorn> looks like the top pour is also connected to ground
2011-11-20T20:34:41 <+Steffanx> Not VCC?
2011-11-20T20:35:01 < Thorn> Vcc is separate (wide traces)
2011-11-20T20:35:35 < Thorn> I've got an unsildered cyclone breakout board where it all is easy to see
2011-11-20T20:35:45 < Thorn> *unsoldered
2011-11-20T20:37:15 <+Steffanx> Tom_itx went to church?

2011-11-20T20:39:16 <+Steffanx> Help? :)
2011-11-20T20:39:45 < Thorn> ^^ nice traces there
2011-11-20T20:49:21 < Thorn> looks like I may need PNP transistors for those LEDs as CAN txd/rxd lines may be high in the idle state
2011-11-20T21:04:28 < grummund> wow. which CAD package is that?
2011-11-20T21:04:51 <+Steffanx> paint grummund

2011-11-20T21:05:29 < Laurenceb_> do USB devices have to support Hardware suspend?
2011-11-20T21:06:16 < Thorn> I seem to recall that if usb traffic stops for some time the device has to lower its power consumption
2011-11-20T21:58:56 < jpa-> Laurenceb_: if they want to be standards compliant
2011-11-20T21:59:40 < Laurenceb_> yeah but does it have to support the pull up resistor thingy
2011-11-20T21:59:56 < Laurenceb_> hang on.. if it goes into suspend how does it come out?
2011-11-20T22:01:13 < Thorn> http://www.beyondlogic.org/usbnutshell/usb2.shtml Entering Suspend Mode
2011-11-20T22:02:24 < Laurenceb_> thanks
2011-11-20T22:03:20 < Laurenceb_> In order to maintain connected to a suspended hub or host, the device must still provide power to its pull up speed selection resistors during suspend
2011-11-20T22:03:28 < Laurenceb_> oh - so thats just for disconnect

2011-11-21T13:21:22 < erik-k> Fucking hell, where do I put "PROVIDE( end = . );" to make minor things like "printf" work?
2011-11-21T13:24:43 < Thorn> dot means current address so you probably place it where you want the symbol to point to
2011-11-21T13:24:57 < Thorn> or something like that
2011-11-21T13:29:29 < erik-k> Okay, following some other cortex .ld and putting it between .bss and ._usrstack
2011-11-21T13:29:56 < Thorn> what's that, something required by malloc()?
2011-11-21T13:30:12 < erik-k> Otherwise _sbrk fails with "undefined symbol" on .end
2011-11-21T13:30:13 < Thorn> I use a uC-friendly printf implementation instead
2011-11-21T13:30:33 < erik-k> It's not just printf, but absurdly atof requires it too
2011-11-21T13:31:56 < jpa-> newlib is annoying :F
2011-11-21T13:32:52 < erik-k> I'm not even going to ask how this linker file knows "._usrstack" means "the stack" when it appears exactly once
2011-11-21T13:37:03 < Thorn> why nobody actually writes a true microcontroller frieldly libc (with broken compatibility where required)? I've even seen the beginnings of STL/iostreams-like library for microcontrollers somewhere, but not the C library
2011-11-21T13:39:33 < Laurenceb> printf sucks
2011-11-21T13:39:41 < Laurenceb> use rprintf from pascal stang or something
2011-11-21T13:39:47 < BadDorf> might as well port a jvm to it ;p
2011-11-21T13:40:18 < erik-k> Now McRae's linker.ld has me completely lost
2011-11-21T13:40:48 < erik-k> How the hell can it possibly know where the stack goes or what "_usrstack" is when that name appears exactly once, anywhere, in any directory?
2011-11-21T13:41:03 < erik-k> .stack I'll believe, but not ._usrstack
2011-11-21T13:43:43 < Thorn> this kind of stuff should be defined in the linker script I believe. as a minimum you need a symbol for beginning of stack+1 so the startup code can place its value into address 0. but with malloc/sbrk you might need a symbol for the begigging of the stack too so it doesn't overwrite the stack (not sure about that)
2011-11-21T13:46:43 < erik-k> Oy.
2011-11-21T13:46:58 < erik-k> Which way does stack grow again?
2011-11-21T13:47:03 < Thorn> down
2011-11-21T13:47:17 < erik-k> okay, so just dumping it at the end of ram is good.
2011-11-21T13:47:17 < Laurenceb> on all architectures?
2011-11-21T13:47:19 < Thorn> heap grows up so it should start right after .bss
2011-11-21T13:47:38 < erik-k> And so I should put end = . right after the .bss then?
2011-11-21T13:47:46 < Thorn> (or .data, not sure which goes first)
2011-11-21T13:48:04 < erik-k> Which... makes that ._usrstack thing some stupid leftover from McRae's other projects
2011-11-21T13:49:53 < erik-k> Right, so, stack at end of ram, heap at end of bss, so when it goes and fucks up this time it's not the heap walking all over everything then...
2011-11-21T13:55:06 < karlp> Laurenceb: no, not on all, but often.  new archs tend to follow it now, so that people stay (relatively) sane
2011-11-21T13:55:25 < Laurenceb> i see
2011-11-21T13:55:36 < jpa-> Thorn: indeed; i ended up using klibc for my libc needs, but it doesn't have atof
2011-11-21T13:56:13 < Thorn> my linker script has end and _end at the end of .bss
2011-11-21T13:57:02 < Thorn> if it's correct, then it marks the start of heap
2011-11-21T13:57:33 < Thorn> http://embdev.net/topic/129161
2011-11-21T13:58:58 < Thorn> never heard about klibc, looks interesting
2011-11-21T13:59:23 < jpa-> http://essentialscrap.com/boat/libraries.html  i called my fork baselibc :P
2011-11-21T13:59:24 < karlp> yet another gpl library
2011-11-21T13:59:47 < jpa-> i think there was some "public domain libc" under development, but it was quite incomplete when i last checked
2011-11-21T14:04:57 < karlp> what's the main advantage of protobufs vs a shared header file with struct definitions?
2011-11-21T14:05:13 < karlp> is it so you don't have to have C on the other side?
2011-11-21T14:13:47 < jpa-> struct definitions are hugely platform dependent
2011-11-21T14:14:11 < jpa-> but yeah, platform and programming language portability mostly
2011-11-21T15:39:15 < Laurenceb> any idea what usb-bot is about?
2011-11-21T15:39:20 < Laurenceb> in um0402
2011-11-21T15:39:25 < Laurenceb> i think its scsi?
2011-11-21T15:40:56 < Laurenceb> trying to delete it all from my project
2011-11-21T15:41:53 < Laurenceb> i dont know what im doing :(
2011-11-21T15:42:02 < Laurenceb> presumably scsi mass storage?
2011-11-21T15:43:28 < Laurenceb> oh it uses scsi
2011-11-21T15:43:30 < Laurenceb> doh
2011-11-21T15:55:15 < Laurenceb> expected specifier-qualifier-list before '__IO'
2011-11-21T15:55:21 < Laurenceb> where is that defined?
2011-11-21T15:56:31 < Thorn> I thibk it's from cmsis,defined as volatile
2011-11-21T15:59:54 < Laurenceb> yeah got it now
2011-11-21T16:00:01 < Laurenceb> hmm just linker errors now
2011-11-21T16:00:10 < Laurenceb> ported all the USB code to my hardware
2011-11-21T16:00:51 < Laurenceb> hmm undefined references
2011-11-21T16:14:05 < Laurenceb> wohoo compiles
2011-11-21T16:53:28 < karlp> but... does it work? :)
2011-11-21T17:44:05 < Laurenceb> heh
2011-11-21T17:44:14 < Laurenceb> i need to do some rework on the board first
2011-11-21T17:44:38 < Laurenceb> i didnt realise usb mass storage used scsi before
2011-11-21T17:48:26 < Laurenceb> this datalogger board is a huge mess now - about 10 wire links
2011-11-21T17:51:10 < Thorn> is it because of scsi? :)
2011-11-21T17:52:34 < Laurenceb> nope - i screwed up the bluetooth

2011-11-21T17:53:00 < Laurenceb> is there a proper protocol for setting real time clock over usb?
2011-11-21T17:53:48 < Thorn> there was an app note on this topic but over tcp/ip
2011-11-21T17:53:49 < jpa-> doubtful
2011-11-21T17:54:45 < Thorn> is your datalogger a commercial project?
2011-11-21T18:00:54 < Laurenceb> yeas
2011-11-21T18:06:47 < jnosky> @erik-k https://sites.google.com/site/stm32discovery/open-source-development-with-the-stm32-discovery/getting-newlib-to-work-with-stm32-and-code-sourcery-lite-eabi
2011-11-21T18:07:28 < jnosky> I added all those stubs but printf doesnt work for me still
2011-11-21T18:07:39 < jnosky> It now links without complaints
2011-11-21T18:07:48 < jnosky> But for some reason, it hard faults
2011-11-21T18:08:26 < jnosky> When I debug, I see the call to printf, but the code it goes to has invalid instructions
2011-11-21T18:08:56 < jpa-> make sure that you are linking to the thumb2 version of newlib
2011-11-21T18:09:22 < jpa-> in particular, you need to define -mthumb also on the linker command line, not only when compiling
2011-11-21T18:15:32 < jnosky> accroding to the debugger, the routine being called is __printf_from_thumb
2011-11-21T18:18:22 < Thorn> that's an interworking stub isn't it?
2011-11-21T18:27:48 < jnosky> tbh I dont really understand how the newlib works
2011-11-21T18:27:56 < jnosky> I get why the stubs are needed
2011-11-21T18:28:08 -!- vpopov [~happylife@dyn-56-47.dzer.fttbee.kis.ru] has joined ##stm32
2011-11-21T18:28:19 < jnosky> But I dont know how the compiler knows where to get the newlib from
2011-11-21T18:28:20 < Thorn> not on cortex-m
2011-11-21T18:28:34 < Thorn> it does not support ARM mode
2011-11-21T18:29:04 < jnosky> The first few opcodes of the printf call are valid
2011-11-21T18:29:17 < jnosky> looks like picks up pointer to string
2011-11-21T18:29:25 < jnosky> Then a BX pc
2011-11-21T18:29:27 < jnosky> nop
2011-11-21T18:29:41 < jnosky> then a bne or something like that, this is where it fails
2011-11-21T18:30:18 < jnosky> What doesnt support arm mode thorn? was that @ me?
2011-11-21T18:30:29 < Thorn> yes
2011-11-21T18:34:02 < jnosky> Whats ARM mode?
2011-11-21T18:34:17 < jnosky> You mean thumb mode? I thought M4 does both
2011-11-21T18:35:04 < Thorn> cortex-m only supports thumb-2
2011-11-21T18:35:06 < karlp> m3 doesn't support arm mode at least, and not thumb either actually, only thumb2
2011-11-21T18:43:48 < jnosky> When I summom arm toolchain doesnt that grab newlib and configure the compiler to use it?
2011-11-21T18:44:50 < jnosky> Oh ok, not thumb but thumb-2, m4 does both, iirc to get best of both, code size wise
2011-11-21T18:45:10 < jnosky> Thats prolly the bne flag its testing, to see if thumb-2 code or not
2011-11-21T18:45:32 < jnosky> But either target of the branch is invalid code...
2011-11-21T18:45:45 < jnosky> Thats where it hard faults
2011-11-21T18:46:46 < jnosky> I added a real small printf.c and it worked, But I still wanna know why newlib aint
2011-11-21T18:47:26 < jnosky> At this point im not sure if its a bad lds or a newlib config problem
2011-11-21T18:47:44 < jnosky> I think the lds is ok, since thats what true studio uses
2011-11-21T18:54:49 < karlp> where lds is a linker script?
2011-11-21T18:59:01 < jnosky> yes sorry I meant ld
2011-11-21T19:00:38 < jnosky> I didnt override any settings for summon arm toolchain, if that matters
2011-11-21T19:01:16 < jnosky> How do I know where the compiler pulls newlib from I wonder?
2011-11-21T19:01:36 < jnosky> I had previously set up arm7tdmi
2011-11-21T19:02:13 < jnosky> But I *think* those are seperate toolchains, ie newlib was configured for that when I built the crosstools
2011-11-21T19:03:26 < jnosky> One thing for sure: __printf_from_thumb is where it chokes
2011-11-21T19:04:24 < jpa-> that does sound like an interworking stub, i don't think there should be one on cortex-m3
2011-11-21T19:05:22 < Thorn> it's perfectly reasonable for a cortex-m to fail trying to execute ARM code
2011-11-21T19:05:56 < jpa-> been there done that

2011-11-21T19:18:45 < jnosky> I do see that BX business there
2011-11-21T19:19:25 <+Steffanx> jnosky you are one of those guys who helped with the stlink v1 on os x?
2011-11-21T19:25:42 < jnosky> No I was the guy who fixed stlink to work with the F4
2011-11-21T19:26:26 <+Steffanx> Hmm, karlp said it was you :P
2011-11-21T19:26:35 <+Steffanx> Then i have to find that other guy he mentioned :)
2011-11-21T19:26:37 <+Steffanx> Thanks anyway
2011-11-21T19:26:44 <+Steffanx> Rious you there?
2011-11-21T19:51:52 < karlp> well, those guys are using stlink on osx,
2011-11-21T19:52:46 <+Steffanx> Yeah, but that's the v2 .. which doesn't use that buggy usb mass storage shit
2011-11-21T19:52:48 < karlp> it's mostly going to come down to whether you can tell OSX to ignore the device and stop trying to use usb mass storage on it I think.
2011-11-21T20:20:06 < emeb> jnosky: thanks for getting the F4 working.
2011-11-21T20:22:07 < jnosky> emeb, yer welcome :)
2011-11-21T20:22:37 < jnosky> Im now working on getting a few of the demos working on F4
2011-11-21T20:22:48 < jnosky> The usb, there are no working examples
2011-11-21T20:23:21 < jnosky> Ive started with the CDC, virtual serial port, and I got the device detected and the serial.sys to load so far
2011-11-21T20:23:38 < jnosky> Just gotta link it to the uart now
2011-11-21T20:23:41 < emeb> Cool. I'm just using my own blinky code, playing with getting the fpu working.
2011-11-21T20:23:47 < Thorn> I'm thinking about designing a f4 demo board... or should I wait for my first one to arrive? :)
2011-11-21T20:25:05 < jnosky> I put a working flash blinker on stlink
2011-11-21T20:25:18 < emeb> Thorn: what do you need that's not on the Discovery board?
2011-11-21T20:25:25 < jnosky> That and the discovery demo
2011-11-21T20:25:36  * emeb would like an audio input codec
2011-11-21T20:25:42 < emeb> and a huge SRAM
2011-11-21T20:25:47 < Thorn> JTAG
2011-11-21T20:26:05 < emeb> JTAG is good...
2011-11-21T20:26:13 <+Steffanx> I want a huge SDRAM emeb
2011-11-21T20:26:33 < Thorn> ARGH diptrace can't edit text objects
2011-11-21T20:26:34 < emeb> Steffanx: yep - that would be good - if the STM32F4xx supported SDRAM
2011-11-21T20:26:39 <+Steffanx> Yeah :P
2011-11-21T20:26:54  * emeb is wondering if it's worth building an FPGA SDRAM controller
2011-11-21T20:27:21 < Thorn> I believe half a meg of SRAM ($2.5?) is enough for an rtos playground
2011-11-21T20:27:30 < jnosky> I wonder if you could use gpio dma somehow to do a psuedo dram interface
2011-11-21T20:27:36 < Thorn> opencores has several sdram controllers
2011-11-21T20:28:11 <+Steffanx> Just get yourself a lpc cortex-m3 with sdram controller :P
2011-11-21T20:28:18 <+Steffanx> IF you can get them though :P
2011-11-21T20:28:30 <+Steffanx> or cortex-m4..
2011-11-21T20:28:57 < emeb> Looks like Freescale has a new Cortex-M4 family coming with SDRAM in the external memory controller
2011-11-21T20:29:05 < Thorn> LPC have a small availability problem
2011-11-21T20:30:07 < Thorn> btw, does f4discovery have ethernet?
2011-11-21T20:30:15 < emeb> nope
2011-11-21T20:31:09 < emeb> just SWD debug, USB OTG, stereo audio out, mono mic in, accelerometer, button, 4 LEDs & GPIO
2011-11-21T20:31:12 < Thorn> I have a few PHYs and magjacks
2011-11-21T20:31:13 < jnosky> The chip does iirc, but no phy
2011-11-21T20:32:56 < Thorn> all that's left is routing some 50MHz and 100MHz signals
2011-11-21T20:33:28 < karlp> Thorn: what do you get with jtag that you don't get with SWD?
2011-11-21T20:33:38 < emeb> more pins

2011-11-22T03:30:02 < jnosky> I figured out my problem, the LIBRARY_PATH was pulling in thumb not thumb2

2011-11-22T05:13:12 < jnosky> Here is the rub, the make file has -mthumb
2011-11-22T05:13:47 < jnosky> I think thats why when I try to link in newlib, it uses the thumb code lib
2011-11-22T05:15:05 < jnosky> There is no -thumb2 option
2011-11-22T05:15:56 < jnosky> So I guess when gcc compiles standard code, and it sees mcpu=cortex-m4 or cortex-m3 it genertaes thumb2 instructions
2011-11-22T05:16:39 < jnosky> BUT when it invokes the linker, and the linker sees -mthumb, it selects the wrong stdlib
2011-11-22T05:17:00 < jnosky> ie: its using the newlib for thumb
2011-11-22T05:17:57 < jnosky> I got around it by using -L/...../arm-none-eabi/lib/thumb2
2011-11-22T05:19:40 < jnosky> Its the only explanation I can come up with, where gcc generates thumb2 opcodes, yet stdlib is using plain thumb
2011-11-22T05:20:25 < jnosky> Am I the only one to actually try to use newlib for thumb2?
2011-11-22T05:21:22 < jnosky> Prolly those pay per view compilers, force thumb2 for newlib, since they dont give you any make files
2011-11-22T05:25:35 < jnosky> You cant omit -mthumb, or you get errors that "target cpu does not support arm mode"
2011-11-22T05:26:18 < jnosky> So you need it in to generate thumb2 code, but leaving it in causes the linker to select the thumb librarires
2011-11-22T05:27:04 < jnosky> for stdlibs

2011-11-22T10:36:46 < karlp> and what were the symptoms again? hardfaults when you try to use any library code?
2011-11-22T10:49:17 < Thorn> I had faults on calling library functions, problem was linking without -mthumb (codesourcery)

2011-11-22T18:05:39 < Laurenceb> heh
2011-11-22T18:06:12 < dekar_> now I don't know whether the multi gigabit transceivers are broken or the software
2011-11-22T18:07:40 < karlp> hehe, someone made a very amateur mistake about locales :)
2011-11-22T18:08:12 < dekar_> I hate locales
2011-11-22T18:08:25 < karlp> they can be somewhat frustrating
2011-11-22T18:08:43 < karlp> partly because there's not many ways for the developer to work out what locale the user actually wants.
2011-11-22T18:09:10 < karlp> on windows, you mighe be better off changing the system locale to get this tool working,
2011-11-22T18:09:15 < dekar_> I once gave a 10k$ bid on ebay cause I used the european comma for cents which then got interpreted as thousands
2011-11-22T18:10:02 < karlp> I can't remember anymore how much notice windows jvms pay to which setting
2011-11-22T18:10:17 < karlp> there's probably a -D flag you can use to set the locale.

2011-11-22T18:17:12 < dekar_> that's my memory throughtput

2011-11-22T18:17:57 < Thorn> what's your clock frequency?
2011-11-22T18:18:07 < dekar_> the FPGA clock? no idea

2011-11-22T22:56:20 < dekar_> what kind of usb issues?
2011-11-22T23:00:19 < Laurenceb_> think ive worked it out now
2011-11-22T23:00:33 < Laurenceb_> i was getting usb suspend and host timeout
2011-11-22T23:00:58 < Laurenceb_> turns out the pullup resistor needs to be enabled when the stm is ready
2011-11-22T23:01:07 < Laurenceb_> i dont have it on a gpio :(
2011-11-22T23:01:57 < Laurenceb_> which will be why it doesnt work :( wire jumper time
2011-11-22T23:03:17 < Laurenceb_> literally have 15 wire jumpers now
2011-11-22T23:06:53 < Laurenceb_> as it was i connected, the processor booted, meanwhile the host didnt get a reply so it ignored the device by the time the usb was initialised on the stm
2011-11-22T23:07:11 < Laurenceb_> devices have to ack the host very quickly
2011-11-22T23:08:01 < Laurenceb_> i guess that explains why usb devices are sometimes not detected if thy arent inserted cleanly
2011-11-22T23:10:13 < Thorn> we discussed that here some time ago, you need to connect that pull up only when you're ready to talk over usb
2011-11-22T23:11:02 < Laurenceb_> so annoying - ive got to do a new pcb now
2011-11-22T23:11:24 < jpa-> also IIRC there was something about disconnecting the pullup when doing actual highspeed communication
2011-11-22T23:11:35 < Laurenceb_> yes
2011-11-22T23:11:36 < jpa-> Laurenceb_: just patch it, can't be that hard
2011-11-22T23:11:52 < Laurenceb_> ill try and do full speed
2011-11-22T23:12:03 < Laurenceb_> jpa-: its a commercial product
2011-11-22T23:12:23 < Laurenceb_> but yeah ill try and fix everything on one v1 pcb, then i know what needs fixing
2011-11-22T23:12:24 < jpa-> so what ,)
2011-11-22T23:12:26 < Thorn> see here http://www.beyondlogic.org/usbnutshell/usb2.shtml#SpeedIdentification
2011-11-22T23:12:29 < jpa-> true
2011-11-22T23:13:11 < Laurenceb_> yeah i just finished reading that XD
2011-11-22T23:14:12 < Laurenceb_> ideally i need to do power properly as well
2011-11-22T23:14:27 < Laurenceb_> ive got a 500ma lipo charger, it should only be enabled after connection
2011-11-22T23:15:11 < Laurenceb_> is that how it works? if you have a 500ma device it wont connect if the host cant support it?
2011-11-22T23:16:11 < Thorn> I have a board powered over usb right now, it's not recognized as a device (no code yet)
2011-11-22T23:16:29 < Laurenceb_> yeah i can draw 500ma without negotiating
2011-11-22T23:16:30 < Thorn> I don't think hosts actually enforce power specifications
2011-11-22T23:16:46 < Laurenceb_> but it should be done properly :P
2011-11-22T23:16:47 < Thorn> also those usb fans, lights and other toys
2011-11-22T23:16:56 < Thorn> they contain no electronics
2011-11-22T23:17:01 < Laurenceb_> yeah

2011-11-22T23:18:09 < Thorn> afaik the host will shut a port down if there's a short from Vbus to ground (or some large corrent)
2011-11-22T23:18:59 < Thorn> but it doesn't have anything to do with bMaxPower (or how i t's called correctly) in the device descriptor
2011-11-22T23:19:11 < Thorn> that's my understanding
2011-11-22T23:19:30 < Laurenceb_> i see

2011-11-23T06:39:46 < Tom_itx> the reg looks like one i used

2011-11-23T06:46:01 < emeb> That reg is an ST equivalent LM1117-3.3
2011-11-23T06:46:50 < emeb> anyway - I've got a buddy with a virtual hosted site who'll lend me a few MB for my files before they disappear.
2011-11-23T06:46:59 < Tom_itx> i used a microchip on a project 500ma
2011-11-23T06:47:05 < Tom_itx> looked similar

2011-11-23T17:42:57 < Laurenceb> i has different file and loaded elf in gdb

2011-11-23T18:08:16 < Laurenceb> same error :(
2011-11-23T18:27:21 < karlp> groovy
2011-11-23T18:27:38 < karlp> it might be trying to use the swd pins?
2011-11-23T18:27:59 < karlp> there's probably gaps in how stlink resets and initializes things?
2011-11-23T18:32:40 < Laurenceb> i dont know
2011-11-23T18:32:47 < Laurenceb> its stuck is _start() now
2011-11-23T18:32:57 < Laurenceb> only happens when i run with jtag
2011-11-23T18:33:02 < Laurenceb> s/jtag/swd
2011-11-23T18:35:26 < Laurenceb> wtf
2011-11-23T18:35:34 < Laurenceb> i can reset it with swd running
2011-11-23T18:35:49 < Laurenceb>  its runs for ~1s then gets stuck in _start
2011-11-23T18:36:50 < Laurenceb> but i think ive managed to work out the logger issues
2011-11-23T18:36:57 < Laurenceb> its to do with initialisation
2011-11-23T18:37:12 < Laurenceb> the card needs a a few hundered ms to ack commands
2011-11-23T18:37:31 < Laurenceb> unfortunately the usb needs to be acked immediately
2011-11-23T18:37:41 < Laurenceb> and needs a running card... this is not good

2011-11-23T19:23:11 < karlp> Laurenceb: so, your device enters standby mode, and SWD doesn't/can't get to it anymore?
2011-11-23T19:23:41 < karlp> should "kill" or something always bring it back from standby?
2011-11-23T19:23:41 < Laurenceb> yeah looks like it
2011-11-23T19:24:06 < karlp> or should connecting to the target leave it as is?

2011-11-23T19:32:30 < karlp> just FYI, I don't have a mac :)
2011-11-23T19:32:30 < peabody124> but when i hit ctrl-c and try and run st-util a second time it give libusb errors
2011-11-23T19:32:45 < karlp> stlink hardware v1 or v2? (which discovery board?)
2011-11-23T19:32:50 < peabody124> F4 discovery board
2011-11-23T19:33:08 < peabody124> yea i'm cool doing some leg work myself just looking for pointers
2011-11-23T19:33:26 < karlp> if you write up what you can, and what output you can see and symptons on the "issues" bit on github, jnosky might have a look.
2011-11-23T19:33:29 < karlp> what are the libusb errors?
2011-11-23T19:33:48 < karlp> there's almost definitely some errors in closing/releasing the libusb data structures,
2011-11-23T19:34:04 < karlp> quite possibly to dow ith asking the "kernel" to release the driver and so forth
2011-11-23T19:34:09 < peabody124> http://pastebin.com/aqyy2ZSW
2011-11-23T19:34:36 < peabody124> attach the issues to which stlink branch?

2011-11-23T19:34:57 < karlp> at least, it's theo nly place issues are being reported.
2011-11-23T19:35:16 < karlp> I take it works if you unplug and replug the board?
2011-11-23T19:35:21 < peabody124> yep
2011-11-23T19:35:34 < karlp> how do you exit the first session?
2011-11-23T19:35:40 < peabody124> but because of this i can't switch between flashing and testing via gdb easily :(
2011-11-23T19:35:46 < karlp> (also, v2 is default, you can leave off the -s 2
2011-11-23T19:35:56 < peabody124> i normally do, just was testing
2011-11-23T19:37:09 < peabody124> i figured it probably wasn't the disconnect code because in both mine and laurence's set up the stlink led stays green at disconnect
2011-11-23T19:38:56 < karlp> try and get a trace from the end of teh first session too, but I really don'y have any idea about usb on macs

2011-11-23T19:42:06 < peabody124> but i'll post to issues
2011-11-23T19:42:12 < Laurenceb> thanks for the help
2011-11-23T19:42:39 < peabody124> on a totally tangential point - with openocd i've been able to say things like "monitor reset" and more importantly "monitor resume" to let the target run and be able to snoop on internal variables while it's running
2011-11-23T19:42:59 < peabody124> is there an equivalent that can be used for st-util?
2011-11-23T19:45:35 < karlp> gdb :)
2011-11-23T19:45:47 < karlp> eventually, most of this should j ust move into openocd
2011-11-23T19:45:59 < peabody124> no i know to use gdb
2011-11-23T19:46:09 < peabody124> but when i try and execute any monitor commands it says they aren't supported
2011-11-23T19:46:12 < karlp> but the codebase for st-util is far simpler
2011-11-23T19:46:17 < peabody124> yea no kidding!
2011-11-23T19:46:25 < karlp> what's the difference between monitor continue and just continue?
2011-11-23T19:46:36 < karlp> I don't know gdb very well at all...
2011-11-23T19:46:49 < peabody124> it's like continue in background versus foreground
2011-11-23T19:46:56 < peabody124> you can't inspect variables without halting execution
2011-11-23T19:47:15 < peabody124> since i'm debugging a speed controller halting execution = 20A going through same phase continuously ;-)
2011-11-23T19:47:46 < karlp> hmm, it shouldn't actually finish starting up and listening when it doesn't recgonise the chip
2011-11-23T19:48:07 < peabody124> no this is when i have something attached all is fine
2011-11-23T19:48:11 < karlp> if it can't recognise the chip, it probably ends up trying to send a usb command which is never answered.
2011-11-23T19:48:21 < peabody124> oh you are talking about debug log
2011-11-23T19:48:26 < karlp> yeah
2011-11-23T19:49:00 < karlp> there's probably lots of extra things that could be added to use the debug module more, like using the SWV for debug output and stuff
2011-11-23T19:49:13 < karlp> but we only recently got flashing working (mostly) reliably
2011-11-23T19:49:25 < peabody124> yeah that stuff is pretty sweet
2011-11-23T19:49:45 < karlp> I'm only just about to start actually writing some _code_ for one of these STM32s this week
2011-11-23T19:49:46 < peabody124> i've been happy with the flashing too (although load via gdb was corrupting things)
2011-11-23T19:49:52 < karlp> (wired up the parts last night)
2011-11-23T19:50:05 < karlp> load via gdb should be working now right?
2011-11-23T19:50:14 < karlp> I wonder if that's the overlapping sections thing...
2011-11-23T19:50:19 < peabody124> well it looked like it was working
2011-11-23T19:50:28 < peabody124> but we have two elfs - a bootloader and the main executable
2011-11-23T19:50:46 < peabody124> i think soemthing is going wrong because of that although the maps have things in the correct place
2011-11-23T19:51:05 < karlp> hmm, report that as an issue too :)
2011-11-23T19:51:21 < karlp> hopefully with enough code or memory maps to be able to reproduce it.
2011-11-23T19:51:30 < karlp> I take it that's a problem regardless of OS?
2011-11-23T19:51:35 < peabody124> will do - right now i _think_ they may even be related cause the st-util seems to get into an odd state
2011-11-23T19:51:37 < karlp> or are you macosx only?
2011-11-23T19:51:44 < peabody124> i can test things on linux boxes too
2011-11-23T19:51:47 < peabody124> but mostly mac
2011-11-23T19:51:54 < karlp> libusb gets very upset if something that was meant to get a reply doesn't
2011-11-23T19:52:08 < peabody124> yea i'm skimming over stlink-usb.c right now
2011-11-23T19:52:08 < karlp> which also happens if you ever get a length wrong
2011-11-23T19:52:35 < karlp> lots of -usb and -sg can be combined now, they're actually both libusb, just with different command wrappings.
2011-11-23T19:52:41 < karlp> "later"
2011-11-23T19:52:57 < peabody124> heh … hmmm that length wrong could definitely be a problem
2011-11-23T19:53:10 < peabody124> if the behavior on osx/linux is different with flushing the remaining buffer on disconenct
2011-11-23T19:53:14 < karlp> oh yeah, if something gets a length wrong, the stlink will keep waiting for the extra bytes,
2011-11-23T19:53:24 < karlp> and not do anything else until it gets them
2011-11-23T19:53:45 < karlp> I got _lots_ of lockups when I was hacking the -sg code for stlink v1 :)
2011-11-23T19:54:00 < karlp> with the same error messages you're seeing.
2011-11-23T19:55:02 < peabody124> ok so i don't think _stlink_usb_close is actually getting called
2011-11-23T19:55:12 < peabody124> you guys hook the SIGKILL and call that?
2011-11-23T19:55:20 < karlp> nope.
2011-11-23T19:55:29 < peabody124> so is there a "proper" way to exit?
2011-11-23T19:55:31 < karlp> seems to be ok on linux :)
2011-11-23T19:55:39 < karlp> well, exiting gdb seems to kill it nicely
2011-11-23T19:55:52 < peabody124> yeah noticed that.  let me try it
2011-11-23T19:56:00 < karlp> hooking ctrl-c to do more cleanup is probably a good idea too.
2011-11-23T19:56:36 < peabody124> ok… good call
2011-11-23T19:56:48 < peabody124> so if i exit gdb then closing happens and i can reconnect
2011-11-23T19:57:33 < karlp> good news :)
2011-11-23T19:57:49 < karlp> add all that to the issue, then anyone else can find it.
2011-11-23T19:57:56 < karlp> seems to be only an issue on osx though,
2011-11-23T19:57:58 < peabody124> already typing
2011-11-23T19:58:05  * karlp cheers
2011-11-23T19:58:07 < peabody124> yeah linux must open a fresh conenction more robustly
2011-11-23T19:58:14 < karlp> I love it when things work out :)
2011-11-23T19:58:52 < peabody124> if you have a chance could you see if _stlink_usb_close gets executed on linux with ctrl-c?  probably adding a signal hook will work cross platform
2011-11-23T19:59:27 < karlp> yeah, it should do.
2011-11-23T19:59:33 < karlp> currently there's no signal hooking at all,
2011-11-23T19:59:40 < karlp> should be pretty straightforward to add
2011-11-23T19:59:43 < peabody124> yea

2011-11-23T20:00:00 < peabody124> so is there a parent close function?
2011-11-23T20:00:05 < karlp> hoping to get a bit of time for this this week, some guy just submitted some major changes to support windows properly too.
2011-11-23T20:00:15 < peabody124> oh nice
2011-11-23T20:00:20 < karlp> parent?
2011-11-23T20:00:31 < karlp> should be an stlink_close() in stlink-common.c iirc
2011-11-23T20:00:33 < peabody124> i.e. i don't want to always call _stlink_usb_close
2011-11-23T20:00:36 < peabody124> ok cool
2011-11-23T20:00:52 < karlp> the -common has most stuff properly delegated to the appropriate backend
2011-11-23T20:00:57 < karlp> hence the _ prefixes,
2011-11-23T20:01:07 < peabody124> hehe intuitivie :)
2011-11-23T20:01:20 < karlp> hopefully :)
2011-11-23T20:01:50 < karlp> unfortunately, netbeans isn't very good at ctrl-clicking through the function pointers to get to the two alternate backends,
2011-11-23T20:02:00 < karlp> but I can't have everything :)
2011-11-23T20:02:06 < peabody124> heh
2011-11-23T20:05:13 < peabody124> ok working.  except i bet no one will appreciate the elegance of making sl a global variable

2011-11-23T23:20:35 < karlp> so..., I did git rebase, and now I wish I hadn't.... )it's already been pushed to github) anyone know how to get back to how it was before?
2011-11-23T23:20:55 < peabody124> tail .git/logs/HEAD
2011-11-23T23:21:05 < peabody124> and you'll see the hash of your previous branch
2011-11-23T23:21:10 < peabody124> git reset --hard HASHTAG
2011-11-23T23:21:57 < karlp> which one and how? stack overflow says this: git reset --hard ORIG_HEAD
2011-11-23T23:22:03 < karlp> I haven't done any other commands yet.
2011-11-23T23:22:15 < karlp> I did a git rebase someremote/master (into my master)
2011-11-23T23:22:26 < peabody124> that ORIG_HEAD might work but i'm not sure how it would know which
2011-11-23T23:23:02 < peabody124> but for example take this line at the end of my log
2011-11-23T23:23:13 < peabody124> 08e74a0b0a06acf007f5b481c4f638b5540df9a0 bf1c02aafb27e525a9032657a3bdb7274061144f <cut email> 1322072826 -0600	merge next: Merge made by recursive.
2011-11-23T23:23:26 < peabody124> the first hash is what i started with before merge and the second hash is after merge
2011-11-23T23:23:31 < karlp> all my lines say rebase: blah
2011-11-23T23:23:53 < peabody124> hmm… crap if that makes a ton of entries it might be risky
2011-11-23T23:24:00 < karlp> it did :)
2011-11-23T23:24:00 < peabody124> you don't have to reset though
2011-11-23T23:24:09 < peabody124> you can also just "git checkout HASH" and check the log
2011-11-23T23:24:13 < peabody124> make sure you find the one you want
2011-11-23T23:24:19 < peabody124> then git reset --hard SPECIFIC_HASH
2011-11-23T23:24:24 < peabody124> which is more conservative

2011-11-23T23:34:01 < karlp> git reset --hard @{1} did all the magic in one go
2011-11-23T23:35:34 < dekar_> you guys seem to know git, do I wanna try that as well?
2011-11-23T23:35:52 < dekar_> so far I am using SVN, but since I mostly do solo projects others just download it works pretty well
2011-11-23T23:36:10 < peabody124> git is great if you need branches
2011-11-23T23:36:15 < peabody124> or do work without internet
2011-11-23T23:36:53 < dekar_> there was this discussion about switching to git at work, but I don't think any of us has tried it yet XD
2011-11-23T23:37:10 < dekar_> I just cloned a few repos, but never used it to commit anything
2011-11-23T23:37:25 < karlp> there are some major headfuckery pieces,
2011-11-23T23:37:39 < karlp> but when you finally get a bit more used to it, it lets you keep track of things really nicely
2011-11-23T23:37:59 < dekar_> I heard you don't commit to others repos, instead you branch them and they pull the changes, is that right?
2011-11-23T23:38:36 < karlp> you can do both...
2011-11-23T23:38:55 < karlp> but yeah, normally you commit them to  your fork
2011-11-23T23:39:08 < karlp> things like github actually make this a little less clear,
2011-11-23T23:39:16 < karlp> as "you" on github is not the same as "you" at home.
2011-11-23T23:39:30 < karlp> and multiple people can push to the same repo
2011-11-23T23:39:39 < karlp> depends what your team looks like.
2011-11-23T23:40:15 < dekar_> I guess we'll have our own git server in the intranet/vpn
2011-11-23T23:40:33 < karlp> yar.
2011-11-23T23:40:34 < dekar_> though lately we have been outsourcing a lot, with horrible results imo
2011-11-23T23:40:42 < karlp> I actually use git-svn with works' svn.
2011-11-23T23:40:48 < karlp> git also is nice for some outsourcing,
2011-11-23T23:40:56 < karlp> you can let them commit their code into their own branches and repos,
2011-11-23T23:41:01 < karlp> and only pull in pieces at a time
2011-11-23T23:41:28 < dekar_> oh, I meant outsourcing like in outsourcing the hosting actually ;)
2011-11-23T23:41:45 < dekar_> administration
2011-11-23T23:42:01 < karlp> well, github et al let you have private repos,
2011-11-23T23:43:03 < peabody124> they also have business packages etc
2011-11-23T23:43:10 < dekar_> do you use any graphical clients? like for diff'ing changes?
2011-11-23T23:43:10 < peabody124> for small groups quite cheap - 25$ / mo
2011-11-23T23:43:24 < peabody124> actually they just released an OSX client that is really pretty
2011-11-23T23:43:28 < peabody124> generally i use command line though
2011-11-23T23:43:53 < peabody124> and we have a crucible web server git.openpilot.org/ that lets us browse the code
2011-11-23T23:44:02 < karlp> man, does windows really not let you print a size_t with %zd?
2011-11-23T23:44:04 < karlp> doh.
2011-11-23T23:45:17 < dekar_> karlp, never even heard of %zd, what's that?
2011-11-23T23:45:27 < karlp> prints a size_t
2011-11-23T23:45:41 < karlp> though, it should be %zu actually.
2011-11-23T23:46:04 < karlp> printf("size is %d", sizeof(blah)); will fail on 64 bit systems,
2011-11-23T23:46:16 < karlp> adding the z makes it work on both, but not on windows.
2011-11-23T23:46:43 < dekar_> oh, didn't know the z - never seen it before
2011-11-23T23:47:00 < karlp> I didn't either until I got a 64bit OS and had to fix some broken code :)
2011-11-23T23:47:33 < karlp> apparently the "best" way is now pritnf("size is %lu", (unsigned long)sizeof(blah));
2011-11-23T23:47:47 < dekar_> I don't really get why it would fail
2011-11-23T23:48:08 < dekar_> I mean size_t is a typedef for unsigned long or something
2011-11-23T23:48:19 < dekar_> it's not that big anyway
2011-11-23T23:49:15 < karlp> no, if you were printing it with %u or %d before, which is fine on 32bit systems,
2011-11-23T23:49:33 < karlp> on a 64 it system, you would get a warning that you were passing an unsigned long when only an unsigned int was expected
2011-11-23T23:51:35 < dekar_> karlp, wouldn't sizeof(int) == sizeof(long) for most systems anyway?
2011-11-23T23:51:44 < karlp> no.
2011-11-23T23:51:47 < dekar_> O.o
2011-11-23T23:51:59 < dekar_> I'd have assumed them both to be 64bit on x64
2011-11-23T23:52:14 < dekar_> but I always use stdint.h anyway
2011-11-23T23:52:25 < karlp> which still doesn't help if you try and print a size_t :)
2011-11-23T23:53:20 < dekar_> I get the problem, but yeah I'd probably just cast in that case as well ;)
2011-11-23T23:53:53 < karlp> http://pastebin.com/DM3Utnd0
2011-11-23T23:55:19 < dekar_> I don't feel like using int/long etc cause of exactly that problem
2011-11-23T23:55:33 < dekar_> I rather define the size I want explicitly
2011-11-23T23:55:55 < dekar_> and I don't have to learn the specific sizes for my platform :D
2011-11-23T23:57:09 < dekar_> wikipedia says on windows x64 systems a long is just 32bit -.-"
2011-11-23T23:57:26 < dekar_> that stuff is far too fucked up
2011-11-23T23:57:39 < karlp> yep, uint64_t and friends are so much easier
2011-11-23T23:58:02 < dekar_> If I'll ever make my own compile I'll make sure char is 7 bit and int is 42bit :D
2011-11-23T23:58:09 < dekar_> *compiler
2011-11-23T23:58:11 < karlp> and no-one will use it :)
2011-11-23T23:58:17 < dekar_> haha
2011-11-23T23:58:22 < karlp> but I think you just reinvented PIC assembly
2011-11-23T23:58:44 < dekar_> I am so glad I went for arm
2011-11-23T23:58:58 < karlp> I'm hoping to become glad :)
2011-11-23T23:59:17 < dekar_> the stm32 is my first ?C platform and I actually considered going for atmel/arduino
2011-11-23T23:59:18 < karlp> I had a bit of fun last night trying to read the alternate functions chart trying to find which pins I could use for SPI :)
2011-11-23T23:59:39 < karlp> and how's it working out for you?
--- Day changed Thu Nov 24 2011
2011-11-24T00:00:08 < dekar_> we have dome guy doing the schematics atm and it's supposed to ship in january
2011-11-24T00:00:21 < dekar_> so I guess it's coming along well :D
2011-11-24T00:00:56 < dekar_> I have been waiting like a year for those schematics (computer science guy myself :/)
2011-11-24T00:01:44 < dekar_> *some guy
2011-11-24T00:03:13 < dekar_> about that alternate SPI pin, isn't there a column for remapped functions in the datasheet, what was the problem?
2011-11-24T00:03:22 < karlp> yeah, I just had to find it.
2011-11-24T00:03:30 < karlp> the details about the spi registers and using it are in the reference manual,
2011-11-24T00:03:35 < karlp> the pin chart is in the datasheet
2011-11-24T00:03:52 < karlp> and I'm coming from simpler uCs, where there is only one pin combination :)
2011-11-24T00:04:10 < dekar_> I see
2011-11-24T00:04:39 < dekar_> that schematics guy has used up all those 21 ADC pins
2011-11-24T00:05:00 < dekar_> I'll have to look into those as well given the STM32 actually just has 3ADC and you have to remap them to read other pins
2011-11-24T00:05:20 < dekar_> he added a ton of shunts and voltage dividers
2011-11-24T00:06:03 < dekar_> the first guy working on it just hooked the adc up to 5V usb voltage and I had to tell him it wouldn't work -.-"
2011-11-24T00:08:33 < dekar_> the new guy added a ton of cool things, switched mode voltage converters instead of those linear ones
2011-11-24T00:09:01 < dekar_> which really makes sense given that we power optical transceivers (including the lasers) via usb
2011-11-24T00:09:19 < dekar_> we'll probably still be over 500mA -.-
2011-11-24T00:10:12 < dekar_> but no one seems to care and if a customer has a problem with that we'll probably just ship them a netbook XD
2011-11-24T00:12:14 < karlp> peabody124: I reckon your issue is actually what legace was hitting too: https://github.com/texane/stlink/issues/30
2011-11-24T00:12:54 < karlp> I had no real clue earlier, but rereading his notes, the key, "it always works at least once" seems to be pretty key :)
2011-11-24T00:13:50 < peabody124> oh yeah looks identical
2011-11-24T00:14:10 < peabody124> so it does affect linux too

2011-11-24T00:29:55 < dekar_> I keep reading stlink all the time, I still don't get what's so cool about it. I am myself using versaloon which supports swd and jtag
2011-11-24T00:30:16 < dekar_> I mean there are even tutorials to flash the versaloon firmware
2011-11-24T00:30:39 < dekar_> I'd probably do that if I had a discovery board
2011-11-24T00:31:15 < peabody124> does the SWD on it work with OpenOCD eyt?

2011-11-24T00:33:47 < dekar_> though I am just using jtag since my board has this 20pin header anyway
2011-11-24T00:33:57 < peabody124> have you tested it?  libswd i don't think is to the point of actually programming chips
2011-11-24T00:34:20 < peabody124> at least i couldn't find any reports of it doign so and the author's writeup lists that as "todo"
2011-11-24T00:34:56 < dekar_> http://www.versaloon.com/bbs/viewtopic.php?f=2&t=2808

2011-11-24T00:35:23 < dekar_> looks like it works
2011-11-24T00:35:29 < dekar_> I can try it next week if you care
2011-11-24T00:36:21 < dekar_> oh that was the jtag programming line I copied, but SWD is right below

2011-11-24T00:38:14 < karlp> yeah, if you have enough working programmers, you can resolder things on your discovery board, and flash versaloon firmware.
2011-11-24T00:38:31 < peabody124> ok cool
2011-11-24T00:38:31 < karlp> or, you could use the board you already have...
2011-11-24T00:38:42 < peabody124> oh really?  yeah i got four discovery boards
2011-11-24T00:39:15 < karlp> yeah, there's some notes out there on which of the solder bridges on which boards you can redo to replace the stlink firmware on the stlink end of the discovery baord with something else.
2011-11-24T00:39:48 < peabody124> well now that st-util doesn't lock up i might be good with that.  just need to get the monitor commands working now
2011-11-24T00:40:14 < karlp> or, see if you can work out how to get the stlink bits into openocd :)
2011-11-24T00:40:46 < dekar_> it's just that people told me they'd run openOCD inside a VM to use stlink -.-"

2011-11-24T00:40:59 < karlp> really?
2011-11-24T00:41:09 < dekar_> I don't get why st didn't open source their stuff anyway
2011-11-24T00:41:23 < peabody124> i gotta get my firmware working so don't want to spend tooo long on getting debugger working
2011-11-24T00:41:30 < karlp> hehe
2011-11-24T00:41:42 < peabody124> it's probably easier to figure out how to get the monitor commands working in stlink
2011-11-24T00:41:51 < dekar_> well I just bought two versaloon and was good to go :)
2011-11-24T00:42:09 < peabody124> yeah i might buy one but it takes 1-2 weeks to arrive
2011-11-24T00:42:19 < dekar_> did that like a year ago :)
2011-11-24T00:42:20 < karlp> sure, you can buy <any existing jtag solution> and any other stm32 board if you like
2011-11-24T00:42:28 < karlp> but, say, a VL discovery board is 8 euros.
2011-11-24T00:42:42 < dekar_> yeah well I don't pay for the stuff I order
2011-11-24T00:42:45 < karlp> and it includes a programmer and debugger that can program other boards
2011-11-24T00:42:45 < dekar_> so idc :P
2011-11-24T00:43:15 < karlp> so, for some people, not paying through the nose for basic tools is a nice thing.
2011-11-24T00:46:42 < peabody124> hehe yup
2011-11-24T00:51:04 < dekar_> discovery wasn't an option for me anyway since it lacked USB
2011-11-24T00:51:23 < dekar_> that was pretty much a showstopper given I wanted to develop an USB device
2011-11-24T00:54:18 < Laurenceb_> heh
2011-11-24T00:54:39 < Laurenceb_> USB isnt nice
2011-11-24T00:54:59 < dekar_> why not?
2011-11-24T00:55:08 < Laurenceb_> overcomplex :P
2011-11-24T00:55:29 < Laurenceb_> guess it seems simpler when you are more familiar with it
2011-11-24T00:55:31 < dekar_> dunno, didn't take me too long to get it working
2011-11-24T00:55:39 < Laurenceb_> just got my first USB device working
2011-11-24T00:55:49 < dekar_> never had anything to do with embedded before
2011-11-24T00:56:12 < Laurenceb_> what are you making?
2011-11-24T00:56:19 < dekar_> I just took the st example and customized the descriptor
2011-11-24T00:56:32 < dekar_> some device to program optical transceivers
2011-11-24T00:56:38 < Laurenceb_> interesting
2011-11-24T00:56:51  * Laurenceb_ is making a medical datalogger with blood pressure monitoring
2011-11-24T00:57:09 < dekar_> http://dl.dropbox.com/u/28467113/IMG_20111114_121240.jpg
2011-11-24T00:57:33 < dekar_> so you basically read a sensor every few seconds and record it? :)
2011-11-24T00:57:59 < Laurenceb_> not quite
2011-11-24T00:58:11 < Laurenceb_> its got ECG and PPG and stuff
2011-11-24T00:58:40 < Laurenceb_> data processing -> fatfs -> SD, then SD mounts as mass storage using USB
2011-11-24T00:58:55 < Laurenceb_> will probably put it on github at some point soon
2011-11-24T00:59:02 < dekar_> what does ppg even mean?
2011-11-24T00:59:14 < Laurenceb_> photoplethysmogram
2011-11-24T00:59:27 < Laurenceb_> optical absorbtion through tissue
2011-11-24T00:59:48 < dekar_> ah those things, I had one in hospital once :)
2011-11-24T00:59:53 < Laurenceb_> load of different wavelenght leds -> fibre -> patient -> photodiode
2011-11-24T01:00:12 < Laurenceb_> the hospital ones are usually dual wavelenght, for oxygen saturation
2011-11-24T01:00:31 < dekar_> they read oxygen saturation, don't they?
2011-11-24T01:00:32 < dekar_> ah yeah
2011-11-24T01:00:39 < dekar_> I think mine did

2011-11-24T11:44:58 < karlp> peabody124: what else is causing the lockups?
2011-11-24T11:45:34 < karlp> I was thinking about it a bit more overnight, I think I'd rather try and find a way to make sure that it reopens properlay/cleanly, rather than trying to catch more escape signals
2011-11-24T11:55:18 < peabody124> yea i was wondering about that too
2011-11-24T11:55:23 < peabody124> i'm also dealing with a really weird issue right now
2011-11-24T11:55:32 < peabody124> where i basically can't get into the chip some times
2011-11-24T11:55:55 < karlp> yep, Laurenceb ran into some yesterday too,
2011-11-24T11:55:59 < peabody124> it keeps returning all 0
2011-11-24T11:56:03 < peabody124> for chip ID
2011-11-24T11:56:05 < karlp> if the chip is in standby it doesn't work, and returns 0s
2011-11-24T11:56:18 < peabody124> well this is when it's running and LED is flashing
2011-11-24T11:56:33 < peabody124> i don't have a the reset line going to my chip though
2011-11-24T11:56:53 < peabody124> did laurence find a fix?
2011-11-24T11:57:10 < peabody124> btw i really like single stepping via stlink - much faster than openocd
2011-11-24T11:58:06 < karlp> good to know.
2011-11-24T11:58:13 < karlp> writing flash is far slower I believe though
2011-11-24T11:58:35 < karlp> laurence's fix was to connect before his code went into standby I believe :)
2011-11-24T11:58:38 < karlp> so.... not really.
2011-11-24T11:58:56 < karlp> I'm also not sure how invasive the connect should be,
2011-11-24T11:58:58 < peabody124> yeah earlier i got it by pulling boot0 high
2011-11-24T11:59:08 < peabody124> i think by default it shouldn't be invasive
2011-11-24T11:59:09 < karlp> it should be possible to connect, but not reset/restart the target
2011-11-24T11:59:22 < peabody124> that's why with openocd the monitor commands are key
2011-11-24T11:59:25 < karlp> to listen to swv for instance
2011-11-24T11:59:28 < karlp> yeah, exactly
2011-11-24T11:59:57 < peabody124> i was wondering  - is the stlink protocol documented or are you guys having to reverse engineer it?
2011-11-24T12:00:08 < peabody124> like for example are there commands like reset chip that are currently not executed?
2011-11-24T12:00:20  * karlp shrugs
2011-11-24T12:00:29 < karlp> it was all reverse engineered, but not by me.
2011-11-24T12:00:44 < peabody124> is there a good site to read for it?
2011-11-24T12:01:08 < karlp> allegedly someone h as some ST source for the stlink, and "we're not missing anything anymore" but we may not be using it all in the right ways
2011-11-24T12:01:19 < karlp> the only site/docs are the code, commit comments
2011-11-24T12:01:52 < karlp> there's some stuff in "to_remove" that contains some old usb packet traces and docs when the stlinkv2 was being added,
2011-11-24T12:02:02 < karlp> I don't know anything about how the stlinkv1 was discovered
2011-11-24T12:02:10 < karlp> all above my head
2011-11-24T12:02:20 < karlp> I'm just more chatty on IRC :)
2011-11-24T12:04:22 < peabody124> ok thank you!  adding stlink_reset(sl) into the gdbserver gets me into it
2011-11-24T12:04:33 < peabody124> in fact fuck that should definitely be in the flash command
2011-11-24T12:05:43 < karlp> who's latest code are you adding? https://github.com/texane/stlink/commit/e9586c100e33fe72e4528b21768bd155a68517e2 fixed that....
2011-11-24T12:05:55 < peabody124> oh it is
2011-11-24T12:06:02 < karlp> I guess it should be in the gdb server somewhere too?
2011-11-24T12:06:19 < peabody124> well that does depend
2011-11-24T12:06:40 < peabody124> for example in my ideal world you would run st-util and it would reliably connect and let you inspect memory contents
2011-11-24T12:06:44 < peabody124> but not disturb running behavior
2011-11-24T12:07:16 < karlp> that does sound ideal.
2011-11-24T12:09:58 < peabody124> ok so another issue i run into a lot: programming with the flash command will erase the flash, say "Successfully unlocked flash" and then hang
2011-11-24T12:10:32 < karlp> stutil hangs? or the target hangs?
2011-11-24T12:10:51 < peabody124> i think target since it persists between powercycling the discovery
2011-11-24T12:11:19 < peabody124> my gut feeling is it starts executing code while it's being uploaded and bad things happen

2011-11-24T14:20:07 < dekar_> with on chip FAT32
2011-11-24T14:20:19 <+Steffanx> The VS1003B mp3 decoder is nice though
2011-11-24T14:20:20 < dekar_> it's some mass storage to SPI IC
2011-11-24T14:20:22 < karlp> (in my completely selfish opinion)
2011-11-24T14:20:28 <+Steffanx> That enc28j60 is only 10mbit, so it sucks
2011-11-24T14:20:41 < dekar_> I would have gone for srm32f107 or f2
2011-11-24T14:20:49 <+Steffanx> Yeah
2011-11-24T14:21:04 < dekar_> also no SRAM on that board, but a ton of NAND
2011-11-24T14:21:47 < dekar_> now he'll come over tomorrow to have me explain to him how to use it
2011-11-24T14:21:59 <+Steffanx> Haha
2011-11-24T14:22:02 <+Steffanx> Good luck
2011-11-24T14:22:36 < dekar_> I surely won't read all those datasheets for the ICs for him
2011-11-24T14:23:26 < dekar_> I guess I'll show him blinky lights or something
2011-11-24T14:24:39 < dekar_> the stm32f107 would have had proper ethernet (still phy needed of) and even usb host support
2011-11-24T14:24:44 < dekar_> *ofc
2011-11-24T14:24:46 <+Steffanx> It's probably worth the money, but it's not a board i would have bought
2011-11-24T14:24:56 <+Steffanx> Indeed
2011-11-24T14:25:34 < dekar_> how do you use those ethernet ICs anyway? sounds like a lot of work to glue that onto some TCP stack
2011-11-24T14:25:59 < dekar_> for the stm32f107 mac you could have just used the lib st provides
2011-11-24T14:26:32 <+Steffanx> I think it's not that hard to make stack for the enc28j60
2011-11-24T14:26:49 <+Steffanx> Just talk to the registers over an SPI connection
2011-11-24T14:27:57 < dekar_> I guess, dunno the IC. But when I looked at the datasheet for that usb host IC it really looked weird. It has commands to create files and so on
2011-11-24T14:28:50 < dekar_> Steffanx, btw, my FPGA board comes with gbit ethernet and has some webinterface
2011-11-24T14:28:58 < dekar_> but I feel like it might be broken
2011-11-24T14:28:59 <+Steffanx> Fancy
2011-11-24T14:29:17 < dekar_> all the self-tests pass, but the one for the multi-gigabit transceivers
2011-11-24T14:30:31 <+Steffanx> Hmm, that kinda sucks for an expensive board like that
2011-11-24T14:31:06 < dekar_> well I'll just return it once I am sure about it
2011-11-24T14:31:16 < dekar_> but annoying yeah
2011-11-24T14:32:49 < dekar_> I liked the huge box it came in :D
2011-11-24T14:32:50 < dekar_> http://dl.dropbox.com/u/28467113/IMG_20111124_001630.jpg
2011-11-24T14:33:17 <+Steffanx> Nice videocard :P
2011-11-24T14:33:33 < dekar_> the fan is incredible loud -.-

2011-11-24T16:41:30 < BadDorf> in my defence, I ordered it a from a uk retailer.. seems they sourced the part from their usa counterpart & shipped it direct to me

2011-11-24T16:46:13 < Laurenceb> what are you using it for?
2011-11-24T16:46:37 < BadDorf> storing pulse widths as a buffer from a floppy drive
2011-11-24T16:47:10 < BadDorf> I could have used an spi fram, but I needed at least 512kbit, and they seemed harder to find
2011-11-24T16:47:10 < Laurenceb> wut
2011-11-24T16:47:32 < Laurenceb> surely you dont needs something that powerful
2011-11-24T16:48:59 < BadDorf> floppy drive, low density, spins at ~300 rpm, one rev every 200ms, one rev = one track, got the rdata line hooked to a pin that can do timer capture, got dma configured to xfer the timer capture reg across to the spi data reg, enable timer, and fram fills up with pulse width data =) .. then disable timer & dma, and use 2nd dma to pull data back from spi & write it back down to the sd card as a file
2011-11-24T16:49:13 < BadDorf> repeat 3x per track, per side, then transfer the whole lot back to the host
2011-11-24T16:49:38 < Laurenceb> wait your doing it with an stm?
2011-11-24T16:49:58 < Laurenceb> thats more sane
2011-11-24T16:50:06 < Laurenceb> thought you were using that fpga
2011-11-24T16:50:12 < BadDorf> fpga?
2011-11-24T16:50:18 < BadDorf> which ?
2011-11-24T16:50:41 < Laurenceb> doh wrong nice nvm
2011-11-24T16:50:44 < BadDorf> the soic8 is an spi fram =)
2011-11-24T16:50:45 < Laurenceb> *nick
2011-11-24T16:50:47 < Laurenceb> :P
2011-11-24T16:50:52 < BadDorf> no probs
2011-11-24T16:50:55 <+Steffanx> lol
2011-11-24T16:51:13 < Laurenceb> using a massive fpga to interface with a floppy would be ... odd
2011-11-24T16:51:26 < BadDorf> not that odd.. depends what you want to do with the data..
2011-11-24T16:51:29 <+Steffanx> over engineering ftw!
2011-11-24T16:51:49 < Laurenceb> http://www.evilmadscientist.com/article.php/googlyshield
2011-11-24T16:51:57 <+Steffanx> When it's a hobby project you can justify it Laurenceb
2011-11-24T16:52:08 < jpa-> fpga's are used for much more mundane things than that
2011-11-24T16:52:16 < BadDorf> pulses can come in at around 3.5us apart at their quickest (for a DD disk, half that for HD)
2011-11-24T16:52:32 < BadDorf> which really doesnt allow much processing time, even in the stm32 @ 72mhz
2011-11-24T16:52:37 < jpa-> at work, they have this system that has FPGA just to capture exact timing of I2C communications
2011-11-24T16:52:48 <+Steffanx> Only a woman can invent something like that Laurenceb
2011-11-24T16:53:11 < BadDorf> so quite a few floppy readers use an fpga up front to do the timing capture, encode the data down into something less time sensitive for the uc to read
2011-11-24T16:54:29 < karlp> Laurenceb: ....?!
2011-11-24T16:55:15 < Laurenceb> its the latest and greatest arduino shield
2011-11-24T16:55:36 < jpa-> it's not as crazy as it first seems :)
2011-11-24T16:55:54 < jpa-> the googly eyes really add to a project
2011-11-24T16:56:08 < Tom_itx> evidently they've run out of stupid things to do with the arduino
2011-11-24T16:56:24 < karlp> no, they've still got plenty of stupid things left
2011-11-24T16:56:40 < karlp> my favourite is defining things like, "number of adc inputs"
2011-11-24T16:56:47 < jpa-> (but for real, it's for mounting a battery or a speaker or similar :)
2011-11-24T16:56:49 < karlp> and then using a number instead of the define.
2011-11-24T16:57:21 < jpa-> karlp: happens all the time when multiple people contribute to the same codebase
2011-11-24T16:57:43 < Laurenceb> some of the backend stuff is good in the libraries
2011-11-24T16:58:04 < Laurenceb> ive used the RF22 mesh network lib on stm32
2011-11-24T16:58:04 < Tom_itx> most of the ppl using it don't have a clue though
2011-11-24T16:58:22 < jpa-> of course they don't, that's why they use the easiest platform
2011-11-24T16:58:52 < jpa-> the point to argue is whether it is good or bad that people without clue can get something done
2011-11-24T16:59:23 < karlp> more googly eyes: http://evilmadscience.com/productsmenu/partsmenu/154-winecharm
2011-11-24T16:59:26 < Tom_itx> the ones that can't go to #avr and pester us for help
2011-11-24T17:00:43 < jpa-> irc users are a minority, after all :)
2011-11-24T17:04:08 <+Steffanx> At least we can point them to #arduino Tom_itx :)
2011-11-24T17:05:44 < BadDorf> heh.. I'm there already ;p
2011-11-24T17:06:01 < BadDorf> couple of ppl in there know stm32 quite well it seems ;p

2011-11-24T17:11:08 < Laurenceb> holy shit 128GB
2011-11-24T17:12:23 <+Steffanx> class 10 :)
2011-11-24T17:12:31 < BadDorf> hehe.. was thinking at lunch.. if I took my floppy disk reader, added write support, loaded an sd card with the TOSEC amiga adf collection, and put it all inside the floppy duplicator unit, with a 16x2 lcd on the front..
2011-11-24T17:12:55 < BadDorf> I could have a unit where you load up empty floppy disks, select which game you want, and it writes the disks for it there & then =)
2011-11-24T17:13:13 < BadDorf> that would be an awesomely bad idea =)

2011-11-25T12:42:08 < Laurenceb> thought my F4discovery wasnt working
2011-11-25T13:35:32 < Laurenceb> odd
2011-11-25T13:35:40 < Laurenceb> SysTick_Config seems to be missing
2011-11-25T13:35:46 < Laurenceb> where should it be?

2011-11-25T14:00:57 < Laurenceb> ITM_SendChar (uint32_t ch)
2011-11-25T14:01:15 < Laurenceb> and NVIC_SystemReset look usefule - from core_cm3
2011-11-25T14:03:30 < jpa-> instruction trace macrocell would be fun if i had something to receive the data :)
2011-11-25T14:06:19 < karlp> is stlink meant to be able to? if you have the right drivers?
2011-11-25T14:06:29 < karlp> or do you need another tool altogether?
2011-11-25T14:06:48 < jpa-> i don't quite know
2011-11-25T14:06:53 < jpa-> i think you need something different
2011-11-25T14:10:05 < karlp> need to read more arm docs I guess
2011-11-25T14:11:33 < jpa-> hmm.. should i code my own matrix stuff atop libfixmath or should i use.. ewww.. ready-made floating point code
2011-11-25T14:12:59 < Laurenceb> jpa-: kalman filter?
2011-11-25T14:13:28 < Laurenceb> karlp: doesnt SWD have all the same functionality as JTAG?
2011-11-25T14:13:35 < jpa-> yeah, kalman filter and other stuff
2011-11-25T14:13:43 < Laurenceb> look at openpilot
2011-11-25T14:13:55 < Laurenceb> they have surely the best EKF for IMU use
2011-11-25T14:14:05 < jpa-> but i don't have an IMU
2011-11-25T14:14:33 < karlp> I woul dhave hoped that all of the ITM and debug console stuff would work over SWD, and over stlink, if all the proper driver support is there, yes.
2011-11-25T14:14:40 < jpa-> (though it does come close.. still i dont
2011-11-25T14:14:58 < jpa-> think a hard-coded measurement function designed for IMU is going to cut it)
2011-11-25T14:36:47 < Laurenceb> is there a difference between blocks and sectors on sd?

2011-11-25T14:37:54 < Laurenceb> im trying to understand the eval code
2011-11-25T14:38:12 < Laurenceb> it has a 'mass storage abstraction layer'

2011-11-25T14:38:22 < Laurenceb> that has a read/write size
2011-11-25T14:38:32 < jpa-> everything is 512 bytes :)
2011-11-25T14:38:33 < Laurenceb> but the eval sd code just uses single block read
2011-11-25T14:38:49 < Laurenceb> so im guessing that measn the transfer size is always 512bytes?
2011-11-25T14:39:17 < jpa-> you never know of ST, they might just have been lazy
2011-11-25T14:39:21 < jpa-> "it works on windows"
2011-11-25T14:39:24 < Laurenceb> lol
2011-11-25T14:39:33 < Laurenceb> well they dont id the card
2011-11-25T14:39:43 < Laurenceb> its going to break on mmc and SDHC
2011-11-25T14:39:49 < Laurenceb> and uses polled spi, lame
2011-11-25T14:40:08 < jpa-> it is an example anyway
2011-11-25T14:40:19 < Laurenceb> ive swapped the storage abstraction thing to use fatfs example interface code
2011-11-25T14:40:22 < jpa-> if you don't have a threading system, using DMA is not going to buy much
2011-11-25T14:40:36 < Laurenceb> i do have threading :P
2011-11-25T14:40:47 < jpa-> but does their example?
2011-11-25T14:40:51 < Laurenceb> no
2011-11-25T14:40:54 < jpa-> indeed
2011-11-25T14:40:55 < Laurenceb> :P
2011-11-25T14:41:42 < Laurenceb> so i guess ill ignore transfer size and read one sector
2011-11-25T14:42:00 < jpa-> how come you are not just using chibios's SD card stuff even though IIRC you were the one to recommend chibios to me? :P
2011-11-25T14:42:10 < Laurenceb> lol
2011-11-25T14:42:18 < Laurenceb> i dont know :P
2011-11-25T14:43:03  * Laurenceb looks up chibios usb support
2011-11-25T14:47:01 < Laurenceb> yeah it looks quite good, but id have to port a lot of code

2011-11-25T14:50:51 < Laurenceb> more than that usually
2011-11-25T15:39:58 < Laurenceb> hmm its not working
2011-11-25T15:40:23 < Laurenceb> connects ok, self tests the card ok, and gets card size, but there filesystem errors
2011-11-25T15:40:57 < Laurenceb> im guessing its reading integer multiples of 512bytes at a time
2011-11-25T15:41:55 < jpa-> printf :)
2011-11-25T15:42:04 < jpa-> the greatest debugging tool

2011-11-25T15:44:39 < Laurenceb> how do i set a breakpoint at function entry and dump the arguments?

2011-11-25T15:46:46 < jpa-> obviously
2011-11-25T15:47:06 < Laurenceb> oh shit
2011-11-25T15:47:14 < Laurenceb> i mixed up read and write
2011-11-25T15:47:26 < Laurenceb> the filesystem probably really is corrupted

2011-11-25T17:27:27 < karlp> hehe, neat
2011-11-25T17:27:35 < karlp> not quite as simple on stm32 :)
2011-11-25T18:23:44 < peabody124> karlp - the difference with the monitor commands is this
2011-11-25T18:23:55 < peabody124> you can load your elf. say monitor reset, monitor resume
2011-11-25T18:24:06 < peabody124> then inspect and change variables while it's running without stopping it at all
2011-11-25T18:24:40 < peabody124> so say you're working on a speed control, you can peek at the current current measurement while it's running then change the timing settings while the thing keeps spinning
2011-11-25T18:30:43 < Laurenceb> oh nice
2011-11-25T18:31:22 < Laurenceb> pretty useful feature
2011-11-25T18:37:40 < karlp> hooray, work's ordering again, I can get an F4 board, unhooray, digikey still refuses to ship 802.15.4 modules.
2011-11-25T18:37:43 < karlp> scumbags
2011-11-25T18:39:34 < Laurenceb> is there a way to force reset over swd?

2011-11-25T18:40:01 < Laurenceb> no
2011-11-25T18:40:03 < karlp> does anyone have nice F100x footprints for eagle?
2011-11-25T18:43:28 < Laurenceb> dont know
2011-11-25T18:43:34 < Laurenceb> look in the libs :P
2011-11-25T18:43:48 < Laurenceb> this is weird - anyone used the fatfs sd spi example code?
2011-11-25T18:44:11 < Laurenceb> i have to init twice with a delay inbetween to make SDHC cards boot
2011-11-25T18:45:07 < Laurenceb> i thought it was the spi line logic levels switching as the spi hardware was enabled, so enabed gpio will pullups
2011-11-25T18:45:13 < Laurenceb> but it still breaks
2011-11-25T19:02:30 < karlp> heh, mouser sells the F100C8 (64k flash, 8k ram) for 50c less than the C4 (16k flash 4kram) in the same package
2011-11-25T19:10:12 < Laurenceb> ok.. made it work, but the code is returning 2.2TB size
2011-11-25T19:10:24 < Laurenceb> with is 512 times 4GB - the actual size
2011-11-25T19:10:43 < Laurenceb> im guessing something isnt working with SDHC
2011-11-25T19:13:26 < Laurenceb> i wonder if this was even tested...
2011-11-25T19:14:39 < karlp> I used the fatfs sd spi example with an avr
2011-11-25T19:14:50 < karlp> but only a one gig sd card, which is not sdhc
2011-11-25T19:15:23 < Laurenceb> yeah
2011-11-25T19:15:36 < Laurenceb> SDSC works fine for me
2011-11-25T19:16:09 < Laurenceb> looks like the number of sectors is returned from the card
2011-11-25T19:16:34 < Laurenceb> if ((csd[0] >> 6) == 1) {	/* SDC version 2.00 */
2011-11-25T19:16:44 < Laurenceb> but theres a different format for SDHC ^
2011-11-25T19:17:09 < karlp> well, did the demo example code says "SD" or "SDHC" ? ;)
2011-11-25T19:17:14 < Laurenceb> maybe that code is broken - its from mikrocontroller.net origionally, and just included with fatfs for example
2011-11-25T19:17:27 < Laurenceb> its supposed to support both

2011-11-25T19:36:06 < Laurenceb> the 1GB uSD ids as SDv2
2011-11-25T19:36:17 < Laurenceb> which int necessarily SDHC aiui
2011-11-25T19:36:27 < Laurenceb> as its doesnt id as having sector based indexing
2011-11-25T19:37:05 < Laurenceb> looks like loads of cammands fail with the SDHC and it defaults to MMC type
2011-11-25T19:37:25 < Laurenceb> i wonder if maybe it doesnt support spi mode properly or something

2011-11-25T20:05:49 < grummund> jnosky: i can't say if the uart code is correct, but check in the vector table to confirm you used the correct name for the Handler function
2011-11-25T20:07:10 < peabody124> laurence - i added the force reset over swd feature to my branch
2011-11-25T20:07:22 < peabody124> err laurenceb for the ping
2011-11-25T20:07:50 < peabody124> you just say "monitor reset" then either continue or "monitor resume" depending on how you want to debug

2011-11-25T20:23:09 < jnosky> The usb works fine, its got an entry in that same it.c file
2011-11-25T20:23:21 < grummund> anyway it was only a guess... ;)
2011-11-25T20:23:24 < jnosky> ahh in startup.S?
2011-11-25T20:23:29 < jnosky> Ill dbl check
2011-11-25T20:25:08 < grummund> I once spent a day or so tracking down why systick would not fire... and it turned out that the vector table symbol differed the code function name by an single '_'.
2011-11-25T20:26:43 < jnosky> Hmm it seems to match...
2011-11-25T20:26:52 < jnosky> DOe sthe NVIC part of main seem ok?
2011-11-25T20:27:05 < jnosky> I saw example code that didnt do that part
2011-11-25T20:27:24 < grummund> i couldn't say
2011-11-25T20:27:28 < jnosky> Also the usb uses irqs, maybe some kinda conflict
2011-11-25T20:27:38 < jnosky> Im gonna try disabling the usb
2011-11-25T20:27:54 < grummund> yep. disabled anything not needed to show the problem
2011-11-25T20:28:13 < jnosky> ok thanks
2011-11-25T20:28:40 < grummund> is the NVIC configuration strictly required?
2011-11-25T20:28:50 < grummund> will it work as default without it?
2011-11-25T20:29:01 < grummund> if so, comment that out too.
2011-11-25T20:30:00 < grummund> i can compare with some working usart code if you still have problems
2011-11-25T21:50:10 < peabody124> so stlink_reset seems to reset the chip downstream of the stlink chip - but is there a way to actually reset the stlink stm32?

2011-11-25T23:57:20 < karlp> peabody124: what else is breaking?
2011-11-25T23:57:42 < karlp> it's probably still unclean disconnects/connects getting it into bad states
2011-11-25T23:57:49 < karlp> or, of course, bugs in the stlink firmware :)
2011-11-25T23:58:03 < Laurenceb_> heh mine often breaks too
2011-11-25T23:58:11 < Laurenceb_> have to unplug
2011-11-25T23:58:22 < peabody124> here's y latest https://github.com/texane/stlink/issues/33
2011-11-25T23:58:39 < peabody124> and i have a workaround for that which is nice.  from 3 programmings down to 1

2011-11-26T16:43:46 < Laurenceb_> where is the SWO interface documented?
2011-11-26T16:43:54 < Laurenceb_> i cant find the electrical spec
2011-11-26T16:45:05 <+Steffanx> swo?
2011-11-26T16:48:56 < TuniLame> hello, I have a STM32Ldiscovery and it don't want to load blinky.elf
2011-11-26T16:49:52 < TuniLame> each time I do that, gdb loads only the .text section (64kb)...
2011-11-26T16:50:02 < TuniLame> do you know what is the problem?
2011-11-26T16:51:06 < jpa-> that is one huge blinky if it has a 64kB .text
2011-11-26T16:51:27 < jpa-> try arm-none-eabi-size -t blinky.elf to see how big it is, maybe it won't fit?
2011-11-26T16:51:37 < TuniLame> sorry, i mean 64bytes
2011-11-26T16:51:53 < jpa-> ah
2011-11-26T16:52:43 < TuniLame> here is the result when I load it: "load blink_32L.elf  Loading section .text, size 0x3c lma 0x20000000 Start address 0x20000000, load size 60 Transfer rate: 779 bytes/sec, 60 bytes/write."
2011-11-26T16:53:21 < TuniLame> (I'm on Ubuntu 10.10 64bits)
2011-11-26T16:53:22 < Thorn> TuniLame: it doesn't run?
2011-11-26T16:53:42 < jpa-> does it have a data section?
2011-11-26T16:54:01 < TuniLame> @Thorn no it don't
2011-11-26T16:54:17 < TuniLame> @jpa what do you mean by "data section" ?
2011-11-26T16:54:54 < Thorn> what does gdb show when you try to run the program?
2011-11-26T16:57:00 < TuniLame> @Thorn : The program being debugged has been started already.\n Start it from the beginning? (y or n) y \nStarting program:
2011-11-26T16:57:42 < Thorn> try this (for openocd): load your.elf; monitor reset init; continue
2011-11-26T16:57:49 < TuniLame> @Thorn it don't really run because the green/red LED blinks, and its not these LEDs that needs to blink
2011-11-26T16:57:56 < TuniLame> @Thorn ok
2011-11-26T16:58:26 < Thorn> then press Ctrl+C to stop and use bt to see where it's stopped
2011-11-26T16:58:41 < Thorn> but you do have something blinking?
2011-11-26T16:59:08 < Thorn> if you had a hard fault it's unlikely that anything would blink
2011-11-26T17:00:23 < karlp> tuni, try the 32l_dac example instead,
2011-11-26T17:01:13 < karlp> the blink_xxxx examples are bad, they try and run from sram
2011-11-26T17:02:38 < karlp> Thorn: say you do bt, and it just says, 0xblahblah in ??()
2011-11-26T17:02:44 < karlp> and Backtrace stopped: previous frame identical to this frame (corrupt stack?)
2011-11-26T17:02:58 < karlp> is that an infinite loop?
2011-11-26T17:03:53 < karlp> ah,
2011-11-26T17:04:04 < karlp> ok, if I do target ext :4242, file myfile.elf, load
2011-11-26T17:04:09 < karlp> then I get proper backtraces
2011-11-26T17:04:16 < karlp> I thought load blah.elf would do it
2011-11-26T17:04:47 < karlp> man, having gdb is getting pretty cool...
2011-11-26T17:05:49 < Thorn> gdb seems to go nuts with any stack corruption. I think there were open bugs against about this
2011-11-26T17:06:06 < Thorn> *against gdb
2011-11-26T17:06:17 <+Steffanx> GDB itself is a bug :P
2011-11-26T17:06:36 < Thorn> also connecting to a running program doesn't seem to work well
2011-11-26T17:06:59 < karlp> oh, when I had the proper symbols loaded, it did the right thing,
2011-11-26T17:07:06 < karlp> it was an infite loop in my code
2011-11-26T17:08:15 < Thorn> although I do remember being able to connect gdb without restarting the target (did "reset halt" in openocd first)
2011-11-26T17:15:20 < Thorn> putting "micro" back into "microcontroller" http://www.atmel.com/dyn/products/product_card.asp?part_id=4558
2011-11-26T17:16:04 < karlp> whee, I've finally done something with my own code
2011-11-26T17:16:40 < karlp> completely trivial of course.
2011-11-26T17:17:08 < karlp> one thing at a time...
2011-11-26T17:17:56 < TuniLame> @Thorn how with the "openocd"?
2011-11-26T17:24:12 < Thorn> TuniLame: are you using openocd? (if you're using discovery then probably not...)
2011-11-26T17:28:53 < karlp> peabody124_ just added monitor support to the stlink gdbserver... so you can do monitor reset and things now,
2011-11-26T17:37:38 < TuniLame> @thorn I'm using gdb, and openocd is installed
2011-11-26T17:37:49 < TuniLame> @thorn I don't know how to use openocd
2011-11-26T17:38:49 < TuniLame> I already tried to compile 32l_dac, but couldn't
2011-11-26T17:41:58 < TuniLame> When making 32l_dac; I have this: "cannot find -lstm32_stdperiph_l1xx"
2011-11-26T17:46:26 < karlp> make -C ../libs_stm/build/
2011-11-26T17:46:31 < karlp> then make again
2011-11-26T17:48:01 < TuniLame> maked with success, what did I do with "make -C ../libs_stm/build/"?
2011-11-26T17:48:23 < karlp> you built the stm32 stdperiph library
2011-11-26T17:48:34 < karlp> make -C issues make in the directory given.
2011-11-26T17:49:32 < TuniLame> ok
2011-11-26T17:49:48 < TuniLame> so I loaded the dac.elf, 1317 bytes/write.
2011-11-26T17:50:15 < TuniLame> but its length is 70Kb, why it loads only 1kb?
2011-11-26T17:50:52 < karlp> arm-non-eabi-size dac.elf says it's only about 4k for me.
2011-11-26T17:50:59 < TuniLame> (I made continue after loading it, and nothing special happened, the green/red LEDs blink as usual )
2011-11-26T17:51:23 < karlp> if you're running the current texane master, you probably need to unplug and replug the board
2011-11-26T17:53:00 < TuniLame> yeaeaeah! I made "run" and the blue/green buttom LEDs beginned to blink!
2011-11-26T17:54:26 < TuniLame> I unplagged and repluggued it, and it automaticly begin de blink, the blue/green... That's what 32l_dac do?
2011-11-26T17:54:27 < karlp> yeah, I'm sorry about the state of the "blink" examples.
2011-11-26T17:54:36 < TuniLame> no problem
2011-11-26T17:54:47 < TuniLame> (it tooks juste 48 hours, :D)
2011-11-26T17:54:49 < karlp> if you hook a meter up to PA4, you should see it slowly increasing too.
2011-11-26T17:54:58 < karlp> 48hrs is better than some of us have done :)
2011-11-26T17:55:07 < karlp> hopefully it will continue to get shorter :)
2011-11-26T17:55:13 < TuniLame> yeah I know, that's why I dont complain ;)
2011-11-26T17:55:34 < TuniLame> ehhh, I'm new to electronic, what is PA4?
2011-11-26T17:56:33 < karlp> one of the pins on the board.
2011-11-26T17:57:01 < TuniLame> I found it
2011-11-26T17:57:09 < TuniLame> how to "meter it up"?
2011-11-26T17:57:59 < karlp> do you have a multimeter?
2011-11-26T17:58:06 < karlp> if not, don't worry about it :)
2011-11-26T17:58:16 < karlp> and just use 32l_dac as the base for your code :)
2011-11-26T17:58:56 < TuniLame> I have a multimeter, but not now,
2011-11-26T17:59:06 < TuniLame> how I need to do with the multimeter?
2011-11-26T18:01:22 < karlp> oh, you could just use it to see what the 32l_dac example code is doing, which is putting a slowly increasing voltage on that pin
2011-11-26T18:03:01 < TuniLame> mmm... so I take the red part of the multimeter on that pin, and the black one on GND?
2011-11-26T18:03:19 < karlp> that would work, it will show -ve voltages that way...
2011-11-26T18:03:27 < karlp> no sorry
2011-11-26T18:03:29 < karlp> brain fart
2011-11-26T18:03:34 < karlp> yeah, that would be right
2011-11-26T18:05:05 < TuniLame> thanks :)
2011-11-26T18:05:37 < TuniLame> I juste tried the 32l_lcd, but didn't see any difference with the 32l_dac... what is it?
2011-11-26T18:11:34 < TuniLame> and do you have a tutorial on how to show something on the LCD?

2011-11-26T18:22:10 < jnosky> You need to add startup code to those projects
2011-11-26T18:22:28 < jnosky> If ya wanna run from flash
2011-11-26T18:23:45 < TuniLame> @karlp and how to get the factory code?
2011-11-26T18:25:58 < karlp> jnosky: the 32l_dac code has the proper startup code,
2011-11-26T18:26:02 < karlp> that's why I refered to it.
2011-11-26T18:26:17 < karlp> blink and 32l_lcd don't
2011-11-26T18:30:22 < jnosky> ahh
2011-11-26T18:31:13 < karlp> TuniLame: I can't find it right now, but somewhere on ST's site is the source, it's appnote AN3413
2011-11-26T18:34:00 < TuniLame> on the AN3964, it says "read the ‘readme.txt’ file in the project folder", but I didn't find any "project folder"...
2011-11-26T18:42:54 < TuniLame> I find it, I installed the firmware, and on the installation directory, where there is the AN3413 exemple... I'm trying to compile it.
2011-11-26T18:58:03 < TuniLame> do you know where is LCD_GLASS_DisplayString (msg) declared?
2011-11-26T19:41:12 < karlp> it's in the stm32l_discovery_lcd.c file..
2011-11-26T19:41:16 < karlp> can you try: https://github.com/karlp/stlink/tree/lcd_flash_test
2011-11-26T19:41:31 < karlp> it should work, with the proper startup files, but my lcd just flickers,
2011-11-26T19:41:37 < karlp> I'm not sure whether my lcd is broken or not.

2011-11-26T19:49:20 < TuniLame> it had been loaded, but the 32l_dac is running, how to replace it with 32l_lcd?
2011-11-26T19:54:37 < TuniLame> the LEDs are blinking as described on the readme file, but there is nothing on the screen...
2011-11-26T20:09:16 < karlp> oh well, maybe that demo never worked...
2011-11-26T20:09:18  * karlp shrugs
2011-11-26T20:09:42 < Tom_itx> check the timing on the lcd signals
2011-11-26T20:09:45 < Tom_itx> maybe it's off
2011-11-26T20:39:37 < karlp> in the very beginning, before I'd ever flashed anything, I could load that 32l_lcd demo into sram, as it originally intended, and it worked flashing "on" "off" on the lcd in time with the leds,
2011-11-26T20:39:49 < karlp> so it's probably still something to do with the init stuff
2011-11-26T21:05:02 < TuniLame> how to delete the files I loaded into the stm32l through gdb?
2011-11-26T21:33:20 < karlp> TuniLame: ok, I've got the LCD demo working,
2011-11-26T21:33:30 < karlp> let me just update some things and I'll push it to github
2011-11-26T21:33:45 < karlp> you don't "delete" them, you just load somethign else
2011-11-26T21:36:33 < TuniLame> aha, and if the thing I loaded don't work on stm32, it just run the old thing...
2011-11-26T21:37:13 < karlp> or, it just keeps running what's broken,
2011-11-26T21:37:17 < karlp> depends what and how you load it
2011-11-26T21:43:01 < karlp> TuniLame: my master at https://github.com/karlp/stlink has a working lcd now...
2011-11-26T21:44:01 < TuniLame> mmm... but how "from flash" ?
2011-11-26T21:45:18 < karlp> pardon?
2011-11-26T21:46:35 < TuniLame> on the readme, there is "From Flash: working", how to do that?

2011-11-26T22:35:51 < Laurenceb_> does st-link v2 support SWO?
2011-11-26T22:36:41 <+Steffanx> What is SWO?
2011-11-26T22:37:06 <+Steffanx> Single wire output? :)
2011-11-26T22:37:37 <+Steffanx> Laurenceb_ ?
2011-11-26T22:37:43 < Laurenceb_> yes
2011-11-26T22:37:56 <+Steffanx> It is really Single Wire Output?
2011-11-26T22:37:57 < Laurenceb_> i know texane doesnt support it
2011-11-26T22:37:59 < Laurenceb_> yes
2011-11-26T22:38:07 < Laurenceb_> but does that actualy hardware support it
2011-11-26T22:38:20 <+Steffanx> LOL, it was just a wild guess
2011-11-26T22:39:46 < Laurenceb_> hhe
2011-11-26T22:39:57 < Laurenceb_> manchester encoded UART data
2011-11-26T22:40:07 < Laurenceb_> very fast clk rate
2011-11-26T22:40:20 <+Steffanx> Or is it Serial wire output?
2011-11-26T22:40:30 < Laurenceb_> im guessing as the stlink uses an stm32 it cant handle very fast baud rates
2011-11-26T22:40:37 < Laurenceb_> just a single wire
2011-11-26T22:42:10 < Laurenceb_> http://www.atollic.com/index.php/targets/stm32
2011-11-26T22:42:19 < Laurenceb_> i might have a play with the lite version on windows
2011-11-26T22:44:29 <+Steffanx> The protocol isn't open is it?
2011-11-26T22:45:05 < Laurenceb_> aiui the SWO protocol is
2011-11-26T22:45:17 < Laurenceb_> bah looks like you need the pro version of atollic
2011-11-26T22:45:42 < Laurenceb_> ill have to have a play with SWO and look at the data on a scope

2011-11-26T22:48:53 < karlp> well, the f103 that handles stlink means it should be able to handle pretty decent baud rates
2011-11-26T22:51:41 <+Steffanx> it runs at 72mhz?
2011-11-26T22:51:49 <+Steffanx> You don't know ofcourse
2011-11-26T22:52:38 < karlp> it at least has the potential :)
2011-11-26T22:58:07 <+Steffanx> " The STMicroelectronics ST-Link adapter does not support SWV or ETM" .. SWV = serial wire viewer
2011-11-26T23:00:43 < karlp> doh
2011-11-26T23:00:49 < karlp> where is tat
2011-11-26T23:01:11 <+Steffanx> Some random website
2011-11-26T23:01:23 < karlp> URL?
2011-11-26T23:01:51 < karlp> stlink just got a whole lot less useful.
2011-11-26T23:02:07 < karlp> I guess I would have knonw that if I'd been using this with fully supported windows tools
2011-11-26T23:02:16 <+Steffanx> It is connected to the f103 on the stm32f4 discovery though
2011-11-26T23:02:51 <+Steffanx> but ..
2011-11-26T23:02:52 <+Steffanx> http://www.naffets.nl/share/a-20111126-220246.png

2011-11-26T23:03:02 < karlp> yeah, I'd seen that...
2011-11-26T23:03:14 < karlp> I wonder if it's just not supported in the firmware on the stlinks?
2011-11-26T23:03:56 <+Steffanx> I guess it means it's not supported by the st-link indeed
2011-11-26T23:04:06 < karlp> hey, Steffanx, does echo $USERNAME do the right thing on OSX?
2011-11-26T23:04:26 <+Steffanx> No result
2011-11-26T23:04:36 < karlp> what about "whoami" ?
2011-11-26T23:04:40 <+Steffanx> echo $USER does
2011-11-26T23:04:48 <+Steffanx> whoami too
2011-11-26T23:04:57 <+Steffanx> os x is pretty bsd compatible ..
2011-11-26T23:05:00 < karlp> making the LCD demo a little tricksier :)
2011-11-26T23:15:28 <+Steffanx> No, give it swo support
2011-11-26T23:23:42 < Laurenceb_> stlink still supports SWO tho?
2011-11-26T23:23:51 < Laurenceb_> whats SWV?
2011-11-26T23:24:27 < Laurenceb_> oh scheduled debug info over SWO?
2011-11-26T23:25:03 < Laurenceb_> atollic claims to support SWO and stlink-v2
2011-11-26T23:25:14 < Laurenceb_> not necessarily at the same time of course
2011-11-26T23:25:48 < Laurenceb_> <karlp> well, the f103 that handles stlink means it should be able to handle pretty decent baud rates
2011-11-26T23:25:55 < Laurenceb_> ^but its manchester encoded data
2011-11-26T23:26:03 < Laurenceb_> not sure how easy it is to decode
2011-11-26T23:27:19 < Laurenceb_> http://www.keil.com/coresight/
2011-11-26T23:27:37 < Laurenceb_> ^ according to that SWV is whatever comes out of SWO ?
2011-11-26T23:28:19 < Laurenceb_> that sucks.. but why does the stlink header on the discovery break out SWO?

2011-11-28T00:40:24 < karlp> windows stuff, plus a linux kernel with usb debugging and all sorts
2011-11-28T00:40:34 < karlp> there's some traces there that might have functions not yet implemented.

2011-11-28T00:44:29 < Laurenceb_> im not sure how the stlink SWO/SWV works
2011-11-28T00:44:43 < Laurenceb_> im guessing it must used the clocked usart mode
2011-11-28T00:44:57 < zippe> You might be able to do it with SPI in slave mode?
2011-11-28T00:45:02 < Laurenceb_> yeah
2011-11-28T00:45:05 < Laurenceb_> thats easy
2011-11-28T00:45:13 < Laurenceb_> theres also a manchester encoded mode
2011-11-28T00:45:19 < Laurenceb_> that can run at up to F_cpu
2011-11-28T00:45:31 < zippe> Huh, poor man's ethernet?
2011-11-28T00:45:32 < Laurenceb_> cant be too easy to rx that with an stm32
2011-11-28T00:45:37 < Laurenceb_> i guess
2011-11-28T00:45:48 < zippe> F_CPU is hard to believe
2011-11-28T00:46:14 < zippe> … just because of the pad drivers
2011-11-28T00:46:29 < Laurenceb_> yeah - this is from the cortex-m3 docs
2011-11-28T00:46:32 < Laurenceb_> not stm32
2011-11-28T00:46:54 < zippe> Oh, right, you're referring to the trace block, not the physical interface
2011-11-28T00:47:09 < Laurenceb_> got to be a pita to receive manchester encoded data that fast without a clk
2011-11-28T00:47:22 < Laurenceb_> well the output gets mapped to a pin
2011-11-28T00:47:24 < zippe> huh?  the whole point of manchester encoding is so that you don't need a clock
2011-11-28T00:47:32 < Laurenceb_> theres a config register
2011-11-28T00:47:35 < zippe> you can recover the clock from the data
2011-11-28T00:47:39 < Laurenceb_> yeah but you need to sink the data
2011-11-28T00:47:54 < Laurenceb_> *syncronise
2011-11-28T00:48:03 < Laurenceb_> unless you have dedicated hardware...
2011-11-28T00:48:37 < zippe> That's more or less what trace is for
2011-11-28T00:48:47 < zippe> IIRC there's flow control on the input to the block though
2011-11-28T00:48:56 < zippe> i.e. if the buffer in the block fills up, it will stop the CPU
2011-11-28T00:49:11 < zippe> I haven't looked at it in detail
2011-11-28T00:49:21 < zippe> btw, has anyone here fought with the F2/F4 USB code?
2011-11-28T00:49:28 < zippe> (i.e. ST's sample code?)
2011-11-28T00:49:32 < Laurenceb_> no
2011-11-28T00:49:36 < Laurenceb_> ive only used F1 usb

2011-11-28T02:38:57 < philpem> who runs zlog? msg'ing it returns a bad URL for the IRC logs.
2011-11-28T02:39:01 < karlp> does anyone have some examples for the systick? the startup asm file ahs .weak SysTick_Handler, but does that mean I just have to provide a function with the right name?
2011-11-28T02:39:41 < jnosky> Yea, it just needs to be the same name as the weak
2011-11-28T02:41:52 < karlp> that's surprisingly easy, if only it was all nicely documented :)
2011-11-28T02:42:01 < karlp> I guess it depends on the startup files you use
2011-11-28T02:42:07 < karlp> and those are highly non-standard I guess.
2011-11-28T02:42:28 < karlp> just the list of vectors is fixed
2011-11-28T02:44:13 < jnosky> The name needs to mach the one in the .S
2011-11-28T02:45:40 < zippe> karlp: Virtually everyone is using the ST-supplied startup files, though I don't understand why,.
2011-11-28T02:45:53 < zippe> ARMv7M is meant to be used with C-based startup code
2011-11-28T02:45:59 < zippe> You should not have to write any assembler at all.
2011-11-28T02:46:06 < jnosky> check it.c too
2011-11-28T02:46:21 < jnosky> systick and a hardfault are defined there already
2011-11-28T02:54:36 < jnosky> Oh I think the discovery f4 demo uses it, you could look at that
2011-11-28T02:56:16 < karlp> awesome.
2011-11-28T02:56:21 < karlp> I have systick
2011-11-28T02:56:27 < karlp> this is starting to fall into place.
2011-11-28T02:56:41 < karlp> zippe: have you got a good example of how to setup the startup in C?
2011-11-28T02:56:54 < karlp> the startup stuff has been proving the hardest to follow.
2011-11-28T02:57:11 < karlp> and the names of things needs to match the linker script.
2011-11-28T02:57:20 < karlp> I'd love to make it a lot simpler...
2011-11-28T02:58:02 < jnosky> Karl all ya gotta do is add the .S and int.c and yer done
2011-11-28T02:58:03 < karlp> I'll have a look at the f4 code a bit more,
2011-11-28T02:58:23 < jnosky> Its kinda like a template
2011-11-28T02:58:24 < karlp> yeah, it was getting the right .S :)
2011-11-28T02:58:36 < karlp> I have it all working nicely now when I got the right template :)
2011-11-28T02:59:09 < karlp> the 32l_dac and 32l_lcd examples now have full startup stuff, so I just added the correctly named systick handler, and now it's working,
2011-11-28T02:59:14 < karlp> still seemed like overly large templates
2011-11-28T02:59:19 < karlp> anyway, learning process for me.
2011-11-28T02:59:20 < karlp> more later
2011-11-28T03:00:23 < jnosky> This way is way easier than what I hadda do for arm7tdmi
2011-11-28T03:00:41 < jnosky> I never heard of "weak" before
2011-11-28T03:03:30 < jnosky> rhe system_stm32f4xx.c handles all the nasty clock setp
2011-11-28T03:03:55 < zippe> Just be aware that code is fairly stupid

2011-11-28T18:18:46 < ben1066> Hey
2011-11-28T18:19:05 < ben1066> So I'm looking to get started with ARM, and I've picked ST as they have the best value that I can find
2011-11-28T18:19:26 < ben1066> Two major points, any good open source toolchains? and any good debugger?
2011-11-28T18:20:57 < ben1066> I plan on getting one of the new STM32F4DISCOVERY boards however I'd like to build some of my own, lower speced, dev boards
2011-11-28T18:20:57 < jpa-> a) codesourcery is fine, prebuilt binary gcc toolchain; there is also a "summon arm toolchain" script floating around if you want to build your own
2011-11-28T18:21:20 < ben1066> jpa-: does codesourcery release sources?
2011-11-28T18:21:24 < jpa-> yes
2011-11-28T18:21:45 < BrainDamage> you can use st-link util from texane & karlp for a gdb interface & flashing util
2011-11-28T18:21:50 < jpa-> but they offer no support for the free version, so if you want sources just use plain gcc
2011-11-28T18:21:58 < BrainDamage> to access the stm32discovery board
2011-11-28T18:22:16 < ben1066> BrainDamage: what about custom dev boards, is there a USART programming interface?
2011-11-28T18:22:17 < jpa-> b) stm32f100 discovery boards have stlink1 which works fine with gdb for me; stm32f4 probably has stlink2 which may or may not work, ask karlp
2011-11-28T18:22:23 < BrainDamage> yes there is
2011-11-28T18:22:27 < BrainDamage> it does work
2011-11-28T18:22:29 < BrainDamage> I have both
2011-11-28T18:22:43 < jpa-> you can use boot0 to program through usart, it works fine but who wants that if you can use SWD and have debugger
2011-11-28T18:22:56 < BrainDamage> this ^
2011-11-28T18:23:10 < ben1066> jpa-: any good debugger then? I plan on some custom barebones boards so I can leave them doing xyz
2011-11-28T18:23:12 < BrainDamage> there's even open source debugger interface firmwares
2011-11-28T18:23:15 < BrainDamage> like versaloon
2011-11-28T18:23:21 < BrainDamage> which is openocd compatible
2011-11-28T18:23:27 < jpa-> ben1066: the stlink built on the discovery boards is fine for debugging
2011-11-28T18:23:38 < BrainDamage> there's even a tutorial how to reflash the st-link chip on the discovery boards with the versaloon firmware
2011-11-28T18:23:39 < jpa-> it also has a connector so you can debug your own board
2011-11-28T18:23:39 < ben1066> It will work with other boards?
2011-11-28T18:23:59 < jpa-> yeah
2011-11-28T18:24:00 < ben1066> jpa-: Great, that seems to be all I need then
2011-11-28T18:24:07 < jpa-> it is not :)
2011-11-28T18:24:10 < jpa-> you need a libc
2011-11-28T18:24:16 < jpa-> and that is were the sadness begins
2011-11-28T18:24:25 < ben1066> newlib crosscompiles fine doesnt it?
2011-11-28T18:24:29 < jpa-> codesourcery comes with newlib, which is fine but way too bloat
2011-11-28T18:24:38 < ben1066> uclibc?
2011-11-28T18:24:42 -!- peabody124 [~peabody12@128.249.96.21] has joined ##stm32
2011-11-28T18:24:43 < jpa-> only for linux
2011-11-28T18:24:52 < jpa-> (not for bare metal)
2011-11-28T18:25:24 < ben1066> dietlibc?
2011-11-28T18:25:32 < jpa-> same thing, only for linux
2011-11-28T18:25:41 < jpa-> pdlibc - maybe; klibc - yeah, but it doesn't have libm and is also otherwise limited
2011-11-28T18:25:41 < ben1066> really?
2011-11-28T18:25:47 < ben1066> it cant be used freestanding?
2011-11-28T18:26:02 < jpa-> AFAIK yes, but can't be sure
2011-11-28T18:26:21 < jpa-> klibc is officially linux-only too, but it was easy to port to bare metal
2011-11-28T18:26:52 < ben1066> klibc is the linux kernel level so yea :p
2011-11-28T18:27:02 < jpa-> yeah
2011-11-28T18:27:12 < Laurenceb> what are you trying to od?
2011-11-28T18:27:18 < Laurenceb> stm32linux?
2011-11-28T18:27:28 < karlp> is it safe to assume you are developing on linux?
2011-11-28T18:27:42 < ben1066> I will be setting up my toolchain on linux
2011-11-28T18:27:58 < ben1066> I gave up with GCC based toolchains on windows long ago :P
2011-11-28T18:28:03 < Laurenceb> heh
2011-11-28T18:28:07 < Laurenceb> me too
2011-11-28T18:28:16 < ben1066> i just run a vm with gcc etc
2011-11-28T18:28:23 < karlp> well, there are alot of other options on windows beside just gcc :)
2011-11-28T18:28:23 < ben1066> then have a shared folder in virtual box
2011-11-28T18:28:29 < karlp> there's things like atollic et al
2011-11-28T18:28:29 < jpa-> codesourcery works fine on windows too :)
2011-11-28T18:29:00 < ben1066> I prefer to keep to toolchains that dont limit what I can do, if i have 1mb flash I want to be able to use it :p
2011-11-28T18:29:10 < jpa-> codesourcery does not limit :)
2011-11-28T18:29:13 < jpa-> it is perfect ,)
2011-11-28T18:29:17 < ben1066> + using propreitary software has shot myself in the foot before
2011-11-28T18:29:27 < ben1066> what library does codesourcery use?
2011-11-28T18:29:34 < jpa-> https://svn.kapsi.fi/jpa/dsoquad/freq/README.txt  there is the procedure i have used to compile on windows using codesourcery
2011-11-28T18:29:46 < jpa-> it comes with newlib pre-built, but can use others
2011-11-28T18:30:06 < karlp> the stlink v1 and v2 on the stm32VL, stm32L and stm32F4 discovery boards all work to program and debug the discovery boards, and also other stm32 targets. (but not all the combinations have been tested)
2011-11-28T18:30:41 < ben1066> Yea karlp I plan on getting a STM32F4 and some other lower price ics
2011-11-28T18:30:45 < karlp> at least for users on linux, the stlinkv1 doesn't work (at all?) on osx
2011-11-28T18:30:55 < karlp> but the stlinkv2 does,
2011-11-28T18:30:57 < ben1066> pretty much ALL arms are better than the AVRs I have been using...
2011-11-28T18:31:01 < ben1066> Thats a though, what does AVR use?
2011-11-28T18:31:09 < jpa-> AVR is 8-bit
2011-11-28T18:31:11 < karlp> what do you mean, what does avr use?
2011-11-28T18:31:27 < karlp> avr doesn't have anything like the debug capabilities of arm, especially cortex m3
2011-11-28T18:31:28 < jpa-> atleast it uses less power :)
2011-11-28T18:31:29 < ben1066> the library
2011-11-28T18:31:36 < jpa-> there is avrlibc
2011-11-28T18:31:39 < karlp> jpa-: not always, stm32L is pretty awesome
2011-11-28T18:31:40 < ben1066> I know its totaly different :P
2011-11-28T18:31:41 < jpa-> it is mostly assembler code
2011-11-28T18:31:48 < karlp> avrlibc is fantastic though,
2011-11-28T18:31:53 < karlp> many years more hacking on it.
2011-11-28T18:31:54 < jpa-> i wish there was something similar for arm
2011-11-28T18:32:13 < ben1066> Make your own :D
2011-11-28T18:32:21 < karlp> I think it will come, just that arm embedded is only just coming out of the companies and into hackers
2011-11-28T18:32:41 < ben1066> heh I know, its like im up to date for once :O
2011-11-28T18:32:45 < jpa-> ben1066: yeah, been there done that based off klibc :)
2011-11-28T18:32:58 < karlp> klibc is gpl though right?
2011-11-28T18:33:03 < jpa-> yeah
2011-11-28T18:33:06 < jpa-> that is a downside
2011-11-28T18:33:08 < ben1066> jpa-: I dont really like GPL, I much prefer BSD
2011-11-28T18:33:36 < jpa-> i think it might be possible to track down the sources of klibc that i have used and prove that they are actually bsd
2011-11-28T18:33:45 < ben1066> have you looked at bionic?
2011-11-28T18:33:48 < jpa-> but klibc development team has not kept track of them so it is not trivial
2011-11-28T18:34:05 < jpa-> no
2011-11-28T18:34:05 < karlp> has anyone here got much to say on programing arm7 vs cortex m3?
2011-11-28T18:34:17 < karlp> is arm7 really much more complicated?
2011-11-28T18:34:17 < jpa-> my PLL on arm7 never started
2011-11-28T18:34:18 < ben1066> i know its targeted at android but its BSD licensed and according to wikipedia smaller than uclibc
2011-11-28T18:34:19 -!- vpopov is now known as happylife
2011-11-28T18:34:26 < Laurenceb> gcc support for arm has progressed massively in the last few years
2011-11-28T18:36:21 < karlp> and will probably continue to improve substantially
2011-11-28T18:36:28 < Laurenceb> its pretty much as good as kiel for lots of stuff imo now
2011-11-28T18:36:46 < ben1066> http://git.kernel.org/?p=libs/klibc/klibc.git;a=blob;f=usr/klibc/LICENSE;h=aa6d7a7e37015f95f852ceb29cc417519919d806;hb=75216b5c62b3b3635ae0c6cf7ee47757d7d99100
2011-11-28T18:37:06 < ben1066> so we just need to find the gnu files
2011-11-28T18:37:09 < ben1066> and rewrite them :p
2011-11-28T18:37:13 < jpa-> or remove them
2011-11-28T18:37:46 < ben1066> then youd have missing headers
2011-11-28T18:38:01 < jpa-> well i doubt the libc headers are derived from linux
2011-11-28T18:38:08 < jpa-> more likely that the syscall etc. headers are
2011-11-28T18:38:26 < jpa-> http://www.netmite.com/android/mydroid/1.5/bionic/libc/string/strtok.c  vs. https://svn.kapsi.fi/jpa/paatti/baselibc/src/strtok_r.c   hmm a bit different design
2011-11-28T18:38:38 < jpa-> i hate that klibc does not have a proper test framework, though
2011-11-28T18:39:32 < jpa-> oh yeah, and tinyprintf
2011-11-28T18:39:38 < jpa-> i really love that, but it is also GPL
2011-11-28T18:41:06 < ben1066> Oh rihgt, so they dont tell you which files have which license
2011-11-28T18:41:59 < jpa-> yeah that is the problem
2011-11-28T18:42:41 < jpa-> and also, there have been changes to some of the files by the klibc folk, so they would have to give a permit to relicense
2011-11-28T18:42:43 < ben1066> One file does
2011-11-28T18:42:51 < ben1066> sys/md.h
2011-11-28T18:42:53 < ben1066> :p
2011-11-28T18:43:33 < jpa-> i think we can live without that :)
2011-11-28T18:43:50 < ben1066> thats the only file Ive found with a GPL header
2011-11-28T18:44:35 < ben1066> Oh there we go, windows search, actually useful :O
2011-11-28T18:45:14 < ben1066> revision.h gzip.h gzip.c deflate.c bits.c minips.c cpio.c jfs_superblock.h md.h zip.c util.c unzip.c trees.c tailor.h
2011-11-28T18:45:21 < ben1066> The files that have "general public" in them
2011-11-28T18:45:32 < karlp> jpa-: does newlib "work" just that you feel it's bigger than it needs to be?
2011-11-28T18:46:09 < jpa-> ben1066: yeah, but those are outside the actual klibc tree
2011-11-28T18:46:16 < jpa-> usr/klibc/LICENSE  is the main issue
2011-11-28T18:46:22 < jpa-> karlp: yeah, it does work
2011-11-28T18:46:45 < ben1066> No.... not ALL of them :p
2011-11-28T18:46:57 < jpa-> karlp: it is just these small things, like making stdio *way* too difficult to interface, writing all the crazy _sbrk stubs that make no sense on an embedded platform etc.
2011-11-28T18:47:15 < ben1066> oh wait sorry your right
2011-11-28T18:48:12 < jpa-> in fact, thanks to that file, as long as the file is not derived from linux kernel, it should be free to use
2011-11-28T18:48:27 < ben1066> Yea
2011-11-28T18:48:37 < ben1066> Except how do you know which are derived, other than they are headers
2011-11-28T18:48:44 < jpa-> some script magic
2011-11-28T18:48:49 < ben1066> It states taht files were derived from the /include directory
2011-11-28T18:48:53 < jpa-> search matching blocks of lines
2011-11-28T18:48:57 < ben1066> So we need to search the header files
2011-11-28T18:49:48 < ben1066> the rest (should) be BSD or "as is"
2011-11-28T18:50:20 < jpa-> printf is still an issue though
2011-11-28T18:50:27 < jpa-> klibc printf only writes to buffers
2011-11-28T18:50:35 < jpa-> which forces this ugggggly thing: https://svn.kapsi.fi/jpa/paatti/baselibc/src/vfprintf.c
2011-11-28T18:51:20 < ben1066>  https://svn.kapsi.fi/jpa/paatti/baselibc/src/vfprintf.c
2011-11-28T18:51:29 < jpa-> that's what I said
2011-11-28T18:51:45 < ben1066> i know
2011-11-28T18:51:48 < ben1066> I accidently pasted it
2011-11-28T18:51:51 < ben1066> PuTTY
2011-11-28T18:52:33 < jpa-> i know :)
2011-11-28T18:59:07  * Laurenceb uses rprintf from pascal stang
2011-11-28T19:00:56 < jpa-> inttypes.h is derived, but easy to rewrite
2011-11-28T19:02:16 < jpa-> ctype.h is similar but has some significant differences even in the similar lines
2011-11-28T19:05:37 < jpa-> actually no
2011-11-28T19:05:44 < jpa-> had a mistake there
2011-11-28T19:06:08 < jpa-> couldn't find any significant similarities for the files that I have used
2011-11-28T19:06:30 < jpa-> (using similarity-tester)
2011-11-28T19:09:13 < karlp> jpa-: the handler_stack in your interrupt_vectors, that's for freertos tasks right?
2011-11-28T19:10:03 < jpa-> karlp: it is for everthing except the freertos tasks
2011-11-28T19:10:10 < jpa-> ie. it is for interrupt handlers
2011-11-28T19:10:37 < karlp> right, ok.
2011-11-28T19:10:50 < karlp> just hving a good look, this looks much nicer than the weird blend of asm startup I have now,
2011-11-28T19:11:04 < karlp> I'd like to have the startup stuff all in C, as ARM intended
2011-11-28T19:11:45 < jpa-> yeah i like it too
2011-11-28T19:11:54 < jpa-> now i don't know where my startup is when i'm using chibios :)
2011-11-28T19:13:14 < karlp> I'm just trying to get a few things up and going to get a bit more understanding before I go all OS
2011-11-28T19:13:41 < jpa-> true
2011-11-28T19:13:49 < karlp> girlfriend just went away for a week with work, so should have some nice quiet nights to get further along on this though :)
2011-11-28T19:14:06 < karlp> it comes together pretty quickly when you have the right examples to look at
2011-11-28T19:15:15 < jpa-> i should finish & clean up this one.. when OS crashes i still need gprs to upload crash dump :)  https://svn.kapsi.fi/jpa/paatti-chibios/bootloader/mini_gprs.c
2011-11-28T19:19:37 < karlp> all the RCC->blah is form the raw cmsis core_cm3.h stuff right? and stm32f10xx.h?
2011-11-28T19:19:58 < karlp> instead of the RCC_SetConfig(somepoitner) stuff that is in the stm32 stdperiph lib?
2011-11-28T19:27:20 < jpa-> yeah
2011-11-28T19:27:24 < jpa-> much cleaner
2011-11-28T19:29:00 < karlp> different at least :)
2011-11-28T19:29:33 < karlp> so, anyone know how well summon-arm-toolchain will work with cortex M0 ddevices?
2011-11-28T19:29:39 < karlp> though it seems only NXP is making them...
2011-11-28T19:32:57 -!- Steffanx [~Steffanx@ip4da726ae.direct-adsl.nl] has joined ##stm32
2011-11-28T19:33:00 -!- mode/##stm32 [+v Steffanx] by ChanServ
2011-11-28T19:35:07 < ben1066> karlp: why wouldnt it work?
2011-11-28T19:35:39 < jpa-> depends on whether gcc works with them
2011-11-28T19:35:59 < jpa-> and it should
2011-11-28T19:36:42 < ben1066> its a subset, so yea, it should
2011-11-28T19:36:53 < ben1066> More importantly does summon-arm work with cortex m4?
2011-11-28T19:37:05 < jpa-> why wouldn't it?
2011-11-28T19:37:23 < ben1066> Well, I know itll work
2011-11-28T19:37:29 < ben1066> But will it use the hardware FPU?
2011-11-28T19:38:46 < jpa-> if you give it the switches
2011-11-28T19:39:20 < karlp> bah, prices on the cortex m0s from nxp aren't cheap enough to warrant,
2011-11-28T19:39:33 < karlp> and nxp's website has a broken link for the datasheet anyway
2011-11-28T19:39:41 < jpa-> i think the point of cortex-m0 is power usage, right?
2011-11-28T19:39:54 < ben1066> Yea pretty much, the STM32 M3s beat the M0 for price
2011-11-28T19:41:19 < karlp> yeah, and the M0 in theory is marginally lower power than the stm32L,
2011-11-28T19:41:39 < karlp> but I can't find enough on it yet, and 230uA/Mhz is still pretty damn low enough for me
2011-11-28T19:41:45 < karlp> (for now)
2011-11-28T19:42:39 < jpa-> i should look more into dynamically changing the frequency
2011-11-28T19:42:40 <+Steffanx> I don't really like the power saving states of an ARM though
2011-11-28T19:42:47 < ben1066> whats the difference between the summon toolchain and plain gcc?
2011-11-28T19:43:10 < jpa-> yeah, the "keep state" power saving state saves almost nothing, and the really low power state losest all memory
2011-11-28T19:43:14 < jpa-> IIRC
2011-11-28T19:43:58 < ben1066> http://gcc.gnu.org/onlinedocs/gcc/ARM-Options.html
2011-11-28T19:44:08 < ben1066> Seems plain gcc supports cortex-m4
2011-11-28T19:47:57 < jpa-> why do i have so much school that i learn all kinds of exciting things and no time to try out them all
2011-11-28T19:49:06 < ben1066> Heh
2011-11-28T19:49:14 < ben1066> Why am I reading not designing a board D:
2011-11-28T19:49:58 <+Steffanx> Yeah, I prefer the power saving states of an AVR
2011-11-28T19:50:48 < ben1066> I rarely do battery stuff, so, albeit it's bad design, ive never used power saving states
2011-11-28T19:51:16 <+Steffanx> me neither.. i just like it :P
2011-11-28T19:52:08  * Tom_itx gives Steffanx a batterymiser card and punches it once for him
2011-11-28T19:52:29  * Steffanx ignores Tom_itx 
2011-11-28T19:54:02 < jpa-> i often use power saving states just to turn device off
2011-11-28T19:55:57 < ben1066> 210 MIPS is pretty impressive...
2011-11-28T19:56:01 < ben1066> For an ARM micro
2011-11-28T19:57:56 <+Steffanx> Not really
2011-11-28T19:58:12 <+Steffanx> Get an dual-core A8 or something like that :P
2011-11-28T19:58:34 <+Steffanx> -n
2011-11-28T20:01:37 < ben1066> micro
2011-11-28T20:01:43 < ben1066> not proccessor, but controller
2011-11-28T20:01:50 < ben1066> also, stm are wierd, they have the cheapest
2011-11-28T20:01:58 < ben1066> but then they get REALLY pricy for the good ones
2011-11-28T20:01:58 < ben1066> :S
2011-11-28T20:02:56 < karlp> that was what it seemed from my research the last few days too, yeah.

2011-11-28T20:04:40 < ben1066> NXP has some large ones in 144 LQFP, Cortex M4/M0 dual cores
2011-11-28T20:04:42 <+Steffanx> Maybe the older ones not..
2011-11-28T20:04:53 <+Steffanx> That are not the big ass ARM's i meant
2011-11-28T20:05:06 < karlp> you mean A* series?
2011-11-28T20:05:07 < ben1066> what did you mean
2011-11-28T20:05:08 <+Steffanx> I meant cortex-a8 and arm's like that
2011-11-28T20:05:11 < jpa-> http://search.digikey.com/us/en/products/STM32F407ZGT6/497-11766-ND/2754210  $18 is not that bad
2011-11-28T20:05:12 < ben1066> oh well then yes
2011-11-28T20:05:13 < ben1066> :p
2011-11-28T20:05:28 < ben1066> jpa-: still more than the dev board afaik :P
2011-11-28T20:06:25 < jpa-> dev board is $19, but yeah
2011-11-28T20:07:06 < ben1066> For me the dev board is a few £ cheaper :P
2011-11-28T20:07:23 < karlp> for 512kb and up, in small volumes, the toshiba and fujitsu and nxp parts have more periphs than the stm32s for teh same price
2011-11-28T20:07:30 < ben1066> Also, I hate the pricing, 1-10 £4.69 10-100 £3.63
2011-11-28T20:07:41 < karlp> the only stm32s cheap are the f1 value line stuff
2011-11-28T20:07:43 < ben1066> you save nearly 25% by buying 10 :S
2011-11-28T20:07:49 <+Steffanx> YAY
2011-11-28T20:08:03 < ben1066> karlp: as I said, low end
2011-11-28T20:08:16 < karlp> ben1066: yeah, I was agreeing with you :)
2011-11-28T20:10:25 < ben1066> :P
2011-11-28T20:10:32 < ben1066> I havent really worked out where TI fit in
2011-11-28T20:11:28 < ben1066> they seem a bit on the pricy side...
2011-11-28T20:13:53 < karlp> I've heard their docs are better
2011-11-28T20:14:07 <+Steffanx> heard. ..
2011-11-28T20:14:10 < karlp> indeed
2011-11-28T20:14:13 < karlp> this is the internet
2011-11-28T20:14:17 < karlp> you expected truth?
2011-11-28T20:14:21 <+Steffanx> Yeah
2011-11-28T20:14:35 < ben1066> They seem to be the "big three" so to speak

2011-11-28T20:14:42 < karlp> this is irc! wild claims and unsubstantianted criticisms are the name of the game!
2011-11-28T20:14:48 < ben1066> USB host mode seems like something thats expensive to find though :S
2011-11-28T20:14:57 < ben1066> At least in small quantities
2011-11-28T20:15:03 < karlp> USB OTG is in most of teh F4s though...
2011-11-28T20:15:18 < ben1066> F4s are £10+
2011-11-28T20:15:19 < karlp> seriously, if you want usb host, have a look at SoCs instead
2011-11-28T20:15:28 <+Steffanx> i like those pops
2011-11-28T20:15:36 < ben1066> I can get usb host in NXP LPC1700s
2011-11-28T20:15:41 < ben1066> They are around £5.50
2011-11-28T20:15:49 < ben1066> SoCs? Any in particular?
2011-11-28T20:15:53 < karlp> http://www.8devices.com/product/3/wi-fi-4-things is neat...
2011-11-28T20:16:08 < karlp> the lpc17xx have usb host?
2011-11-28T20:16:14 < karlp> I thought just usb device.
2011-11-28T20:16:18 <+Steffanx> I want a raspberrypi karlp :P

2011-11-28T20:16:39 < karlp> get rid of the honking big old tower pc in the living room, that's just there for video playback
2011-11-28T20:16:50 < ben1066> karlp: some of the 1750 and 1760 have it
2011-11-28T20:16:52 < karlp> replace it with a rasberry pi and a laptop usb harddrive
2011-11-28T20:17:27 < ben1066> so yea, which SoCs?
2011-11-28T20:17:47 < karlp> well, that ralink, or the atheros ones
2011-11-28T20:17:58 < karlp> not sure how easy any of them can be gotten in small parts
2011-11-28T20:18:16 < karlp> but running a full linux on a tiny board like that can make some of the programming a lot simpler

2011-11-28T20:18:37 < jpa-> beaglebone seems nice, too
2011-11-28T20:18:44 <+Steffanx> and more expensive
2011-11-28T20:19:08 < ben1066> thats the issue, the SoCs are still very much industrial
2011-11-28T20:19:11 < jpa-> yeah, but you can actually buy that unlike rasberry pi :)
2011-11-28T20:19:58 <+Steffanx> Sure?
2011-11-28T20:21:05 < ben1066> I think I may just have to do without USB host on my little dev boards :(
2011-11-28T20:21:07 <+Steffanx> oh yes
2011-11-28T20:21:28 <+Steffanx> usb is a pita anyway
2011-11-28T20:21:33 < karlp> ben1066: what usb devices were you planning on connecting anyway?
2011-11-28T20:22:57 < jpa-> i wonder if usb otg would work as a host for any device?
2011-11-28T20:25:06 < ben1066> karlp: Not sure, I just like the avaliablity, android uses usb host for accessories, usb flash drives are cheaper than sd cards, keyboards
2011-11-28T20:26:03 < ben1066> then again the LPC1754 is only £4.50
2011-11-28T20:26:25 <+Steffanx> You realyl care about every pound for a single dev board ?
2011-11-28T20:27:15 < ben1066> Well no, but its nice to have the option to leave something built
2011-11-28T20:29:22 < ben1066> but I guess just usb device would do...

2011-11-28T20:36:26 < ben1066> the issue is my plan is to build a few boards so I can just build them into something without worrying about cost so much, hence the reason I want it to be fairly cheap
2011-11-28T20:39:33 < ben1066> I might make a board with the traces for USB host, in the LPC1750 series, however, if I use it with a micro without usb host I just wont connect it, I guess they are otherwise pin compatible?

2011-11-28T21:46:39 < jpa-> 10% of bit time is still 10%
2011-11-28T21:46:56 < jpa-> only thing is that the rise & fall times cut your margin a bit
2011-11-28T21:46:57 <+Steffanx> Then you still have to tweak it for each device..
2011-11-28T21:47:01 <+Steffanx> Which is a little bit odd imho
2011-11-28T21:47:37 < jpa-> no need to tweak if the oscillator is accurate enough (depends on temperature, vcc etc.)
2011-11-28T21:47:51 <+Steffanx> The question is.. how accurate is it :)
2011-11-28T21:48:50 < jpa-> 2%.
2011-11-28T21:49:08 <+Steffanx> 2.5 .. for the 103
2011-11-28T21:49:34 <+Steffanx> And 1% if you go for 'user trimmed'
2011-11-28T21:57:53 < karlp> jpa-: yeah, but if I'm 10% off at 9600, I might still fall into what's acceptable at 9600,
2011-11-28T21:58:00 < karlp> but not at 115200
2011-11-28T21:58:54 < karlp> I think...

2011-11-28T22:00:04 < karlp> is the 6 pin row on the stlinkv2 a common enough format? or is swd not standardised at all?

2011-11-28T22:22:24 < Tom_itx> funny how parts get named
2011-11-28T22:24:27 < jpa-> karlp: nope, the word length is always 10 bits for 8N1 RS232; therefore, maximum acceptable theoretical clock drift between sender and receiver is 10% - rise/fall times; therefore if HSI is 2.5% accurate, it should be fine for whatever baudrate until rise/fall times start to be a significant portion of the bit width (which they shouldn't be if you use the 50MHz output pin mode)
2011-11-28T22:24:30 <+Steffanx> I don't have win 7 anymore Tom_itx
2011-11-28T22:25:52 < karlp> jpa-: that's good for me, son on avr, with an internal rc oscillator only rated to 10Mhz, you normally need a crystal/resonator,
2011-11-28T22:26:04 < karlp> but at 2.5% for the HSI on stm32, I should be fine without it.
2011-11-28T22:26:57 < karlp> Steffanx: my reading ending up deciding that SWV and SWO were confusingly interchangeable names for getting trace data out of the core, and SWD was the name for the SWDIO and SWDCLK pins that let you program and do some more invasive debugging.
2011-11-28T22:27:06 < Laurenceb_>  have you heard about the raspberry pi GPU?
2011-11-28T22:27:06 < Laurenceb_>  its raspberry rippled
2011-11-28T22:27:24 <+Steffanx> That quote is from a line in the ARM documentation karlp
2011-11-28T22:27:29 < jpa-> karlp: AFAIK the issue is more often that the baudrates you can get exactly by the divider are limited
2011-11-28T22:28:56 < jpa-> ie. no way to divide 8MHz with an integer to get 921600 bps
2011-11-28T22:29:10 < jpa-> while 24MHz divides neatly

2011-11-28T23:06:04 < Laurenceb_> you can configure register dumps and things, and also data from the ITM over the SWV
2011-11-28T23:06:47 < Laurenceb_> you can also configure the SWO protocol - manchester encoded asynchronous - very fast, of synchronous usart synced the SWDCLK
2011-11-28T23:06:55 < Laurenceb_> thats all documented
2011-11-28T23:07:03 < Laurenceb_> and aiui its supported by OpenOCD
2011-11-28T23:07:11 < Laurenceb_> using syncronous usart mode
2011-11-28T23:07:35 < Laurenceb_> Stlink v2 supports SWO in syncronous mode, but the usb commands need to be reverse engineered
2011-11-28T23:08:12 < Laurenceb_> i think itd be a lot of work to add proper SWV protocol support to the st-link utility
2011-11-28T23:08:28 < Laurenceb_> maybe if raw data could be piped to OpenOCD?
2011-11-28T23:09:10 < dekar_> Steffanx, you could use the FPGA to make your SWD hit the 4MB/s you were talking about? :P
2011-11-28T23:09:16 < Laurenceb_> IIRC OpenOCD have SWV working with J-Link.. im not 100% sure
2011-11-28T23:09:23 < Laurenceb_> heh
2011-11-28T23:09:39 < Laurenceb_> dekar_: aiui in manchester you can go _really_ fast
2011-11-28T23:09:40 < dekar_> and then do that like 500 times in parallel
2011-11-28T23:10:02 < Laurenceb_> the baud can be up to F_APB/2
2011-11-28T23:10:05 < dekar_> oh well, go 10Gbit/s then :D
2011-11-28T23:10:13 < Laurenceb_> 36Mbps
2011-11-28T23:10:24 < dekar_> *cough* boring *cough*
2011-11-28T23:10:49 < Laurenceb_> heh there usb2 FS for that i guess
2011-11-28T23:11:09 < Laurenceb_> but it owns for debugging
2011-11-28T23:11:48 < Laurenceb_> doesnt versaloon firmware support SWD on the discovery?
2011-11-28T23:11:52 < Laurenceb_> if you reflash
2011-11-28T23:15:59 < ben1066> can st link only program st micro arms?
2011-11-28T23:17:14 < karlp> that's what they say,
2011-11-28T23:17:26 < karlp> at least, with the original stlink firmware
2011-11-28T23:17:31 < ben1066> Ah I see
2011-11-28T23:17:57 < ben1066> what about the lpcxpresso programmer?
2011-11-28T23:18:03 < ben1066> only lpcs?
2011-11-28T23:18:12 < karlp> I believe it has similar limitations, but I've not used it.
2011-11-28T23:18:26 < dekar_> Laurenceb_, I'd guess it does, but I don't have any discovery boards to try it
2011-11-28T23:18:32 < karlp> I'm not itching to try and get started with multiple different arm vendors :)
2011-11-28T23:19:41 < ben1066> karlp: heh, the thing ive found is that LPC are good for everything but USB and ethernet
2011-11-28T23:19:44 < ben1066> stm*
2011-11-28T23:20:04 < ben1066> and that LPC are also a bit faster at similar cost

2011-11-29T00:01:01 < Laurenceb_> ben1066: ive just got the um0424 USB mass storage example code running on f103
2011-11-29T00:01:07 < Laurenceb_> took alot of work
2011-11-29T00:01:26 < Laurenceb_> its still too slow :(
2011-11-29T00:01:32 < ben1066> The thing is, I want some cheap ones to work with, under £4
2011-11-29T00:01:51 < ben1066> NXP have the LPC1751 with USB, 100mhz, ADC, RTC,
2011-11-29T00:02:04 < Laurenceb_> whats the firmware situation like for it?
2011-11-29T00:02:12 < Laurenceb_> is it as easy to use as stm32?
2011-11-29T00:02:24 < ben1066> not sure
2011-11-29T00:02:53 < Laurenceb_> i still have the issue that my device is 12Mbps USB2
2011-11-29T00:03:03 < Laurenceb_> its supposed to be full speed
2011-11-29T00:03:07 < ben1066> Afaik there are on chip usb drivers in ROM
2011-11-29T00:03:11 < Laurenceb_> any idea how that could happen?
2011-11-29T00:06:07 < ben1066> No ;S
2011-11-29T00:06:56 < Laurenceb_> usb is too complex for its own good
2011-11-29T00:07:16 < Laurenceb_> ubuntu is showing USB2 high speed device :(
2011-11-29T00:07:28 < Laurenceb_> and its only getting 600KB/s throughput
2011-11-29T00:08:03 < Laurenceb_> even tho i rewrote it to use DMA with multisector buffering
2011-11-29T00:08:19 < Laurenceb_> should be about 2MB/s
2011-11-29T00:15:35 < dekar_> I am glad I never cared for the speed of my USB - flashing a 20kb firmware using my bootloader takes like 5s :P
2011-11-29T00:16:19 < Laurenceb_> im making a datalogger - commercial project
2011-11-29T00:16:37 < Laurenceb_> well - it logs data as part of the many other jobs :P
2011-11-29T00:18:02 < dekar_> commercial project here as well
2011-11-29T00:18:45 < dekar_> it's just that we used to do i2c using an FT2232c, thus switching to the stm32/usb-hid was a major speedup already
2011-11-29T00:19:32 < dekar_> those FTDI things really suck for I2C, the clock randomly pauses for up to seconds in the middle of transactions - many slaves crashed on me :/
2011-11-29T00:19:54 < dekar_> crashed like in required power cycles
2011-11-29T00:20:23 < dekar_> I think the FTDI is basically bit-banging I2C via USB (using their proprietary MPSSE protocol)
2011-11-29T00:20:43 < dekar_> since USB sucks for real time the resulting I2C sucks as well
2011-11-29T00:21:46 < karlp> heh, board layout for stm32 is not nearly as easy as for bigger pitch stuff. especially trying to avoid vias, as our boards don't hvae through hole plating.
2011-11-29T00:21:58 < karlp> admittedly, board layout's not my strong point, but this is tedious
2011-11-29T00:22:18 <+Steffanx> seeed is cheap.. so why ou care about via's karlp :)
2011-11-29T00:22:21 < dekar_> I should really learn layouting one day
2011-11-29T00:22:28 < karlp> we have a mill in the office,
2011-11-29T00:22:45 < karlp> it can do double sided fine pitch smd, but vias, I have to put them in myself :)
2011-11-29T00:22:58 <+Steffanx> That's not that hard
2011-11-29T00:23:07 < karlp> no, but it's tedious.
2011-11-29T00:23:09 <+Steffanx> You just need the right tools
2011-11-29T00:23:24 <+Steffanx> but seeed is easier
2011-11-29T00:23:26 < karlp> I'm just used to being able to run traces between teh pads if need be
2011-11-29T00:23:34 < karlp> seed is much much much slower to iceland.
2011-11-29T00:23:44 <+Steffanx> 2-3 weeks to the netherlands ..
2011-11-29T00:24:07 < dekar_> From what I read the altera-blaster (jtag) is basically an FTDI with a changed PID/VID - I really wonder why they did that. Windows throws a ton of huge warnings installing their unsigned driver, though they could have used the standard FTDI driver which ships with every copy of windows :/
2011-11-29T00:24:20 < karlp> 2-3 weeks is so so much slower than 2 hours in the lab.
2011-11-29T00:24:34 <+Steffanx> True, but I don't really care about that
2011-11-29T00:24:35 < karlp> dekar_: "product differentiation"
2011-11-29T00:24:44 <+Steffanx> 2 hours in the lab = 2 hours wasted :P
2011-11-29T00:25:08 < karlp> no, I meant while waiting for the machine to make it here
2011-11-29T00:25:08 < dekar_> karlp, what do you mean? they could have written custom strings to the FTDI EEPROM
2011-11-29T00:25:18 < dekar_> we used to do that for the old product
2011-11-29T00:25:58 <+Steffanx> Anyway gn
2011-11-29T00:26:05 < dekar_> night
2011-11-29T00:26:09 < karlp> good night
2011-11-29T00:26:50 < dekar_> I got a free palm Vx today and I wonder whether I want to hack the IR transmitter to be stronger and use it as universal remote
2011-11-29T00:27:08 < dekar_> could replace all of my four remotes lying around
2011-11-29T00:27:15 < dekar_> it even has backlight
2011-11-29T00:27:37 <+Steffanx> dekar_ and his free products
2011-11-29T00:28:00 <+Steffanx> How's your ps3 dekar_ ?
2011-11-29T00:28:20 < dekar_> didn't bother hacking it yet - sits next to my 360 though
2011-11-29T00:28:24 < dekar_> barely play anyway
2011-11-29T00:28:48 <+Steffanx> It's still a weird story
2011-11-29T00:28:53 < dekar_> I know
2011-11-29T00:29:19 <+Steffanx> :P
2011-11-29T00:29:24 <+Steffanx> Write a book about it :)
2011-11-29T00:29:38 <+Steffanx> It'll be a bestseller, fantasy :)
2011-11-29T00:29:43 < dekar_> haha, not enough story for a book, haven't even heard from that guy since then
2011-11-29T00:29:50 <+Steffanx> Haha
2011-11-29T00:29:53 < dekar_> mailed him a few times but he didn't respond
2011-11-29T00:30:42 < dekar_> and he has this thing? throwing his phones against the wall regularly, so his old cell phone number doesn't work anymore and I don't know how to reach him
2011-11-29T00:30:55 < dekar_> weird guy
2011-11-29T00:33:17 < dekar_> Steffanx, I got my teensy++ board though, did I tell you that?
2011-11-29T00:33:30 < dekar_> just cbf soldering those 50 pins up to the NOR flash
2011-11-29T00:33:32 < Tom_itx> is that a 1287?
2011-11-29T00:33:46 < Tom_itx> host mode
2011-11-29T00:34:15 < dekar_> dunno what a 1287 is actually
2011-11-29T00:34:20 < dekar_> the teensy is some AVR
2011-11-29T00:34:32 < dekar_> but I am really not into atmel so idk what it is
2011-11-29T00:34:50 -!- Steffanx [~Steffanx@ip4da726ae.direct-adsl.nl] has quit [Ping timeout: 252 seconds]
2011-11-29T00:35:10 < Tom_itx> why'd you get it then?
2011-11-29T00:35:38 < dekar_> to solder it up to my PS3s NOR flash and program it
2011-11-29T00:35:58 < dekar_> some PS3 someone gave me earlier this year, haven't used it yet
2011-11-29T00:36:05 < dekar_> felt like at least hacking it :)
2011-11-29T00:36:19 < dekar_> it kinda works like an open source modchip
2011-11-29T00:36:35 < dekar_> the project is called NORway iirc
2011-11-29T00:37:20 < Tom_itx> that isn't that psgroove thing is it?
2011-11-29T00:37:41 < dekar_> nope, that stopped working a while ago
2011-11-29T00:37:47 < Tom_itx> i figured
2011-11-29T00:38:39 < dekar_> now you have to solder 50 cables up to the address and data bus of the NOR chip
2011-11-29T00:38:47 < dekar_> and I hate soldering :P
2011-11-29T00:38:56 < Tom_itx> smt chip?
2011-11-29T00:39:04 < Tom_itx> use wirewrap wire
2011-11-29T00:39:05 < dekar_> yeah
2011-11-29T00:40:29 < Tom_itx> so how's the teensy gonna help you with that?
2011-11-29T00:40:33 < dekar_> I actually thought about using some really fine litz
2011-11-29T00:40:35 < Tom_itx> it's not 50 pin
2011-11-29T00:40:43 < dekar_> well maybe it was 40 pins
2011-11-29T00:40:45 < dekar_> still a ton
2011-11-29T00:40:56 < dekar_> it uses most of the teensy pins
2011-11-29T00:42:23 < dekar_> Tom_itx, http://psx-scene.com/forums/attachments/f149/29584d1309926619-norway-teensy-2-0-flasher-software-norway4.jpg
2011-11-29T00:42:59 < dekar_> I think it's using some pads on the teensy++ which weren't actually meant to be used
2011-11-29T00:43:15 < Tom_itx> if it's a pad, it's meant to be used
2011-11-29T00:43:28 < dekar_> well not for breadboarding I mean
2011-11-29T00:43:40 < dekar_> the teensy is supposed to be plugged into a breadboard I think
2011-11-29T00:43:51 < Tom_itx> no, there are just too many pins to cleanly make a dip board from it
2011-11-29T00:44:06 < Tom_itx> so they just stick em on the end
2011-11-29T00:44:14 < Tom_itx> or whereever
2011-11-29T00:44:44 < Tom_itx> http://tom-itx.dyndns.org:81/~webpage/boards/atmega32u4/atmega32u4_1.jpg
2011-11-29T00:44:51 < Tom_itx> that one likely doesn't have quite enough pins
2011-11-29T00:45:17 < dekar_> yeah w/e - I haven't looked into the teensy and didn't really care actually. the NORway projects uses the teensy as their reference hardware so I bought it
2011-11-29T00:45:39 < dekar_> mine is the teensy++ 2.0
2011-11-29T00:46:10 < dekar_> http://www.pjrc.com/store/tpp_main.jpg
2011-11-29T00:46:11 < Tom_itx> iirc that's a at90usb1287
2011-11-29T00:46:14 < Tom_itx> i know
2011-11-29T00:46:38 < dekar_> it's supposed to work, thus I got it
2011-11-29T00:46:38 < Tom_itx> 1286
2011-11-29T00:46:43 < Tom_itx> same thing but not host mode
2011-11-29T00:46:54 < dekar_> didn't plan on playing with it besides the NOR flash
2011-11-29T00:47:05 < Tom_itx> nor will fade then you can
2011-11-29T00:47:17 < dekar_> fade?
2011-11-29T00:47:29 < Tom_itx> the hack will go away soon enough, then you can play with it
2011-11-29T00:47:41 < dekar_> also I plan on keeping it soldered and leaving it inside the case in case I need to flash it again later
2011-11-29T00:47:47 < Tom_itx> what's it supposed to do?
2011-11-29T00:48:00 < dekar_> replace the firmware of the PS3
2011-11-29T00:48:06 < Tom_itx> ahh
2011-11-29T00:48:18 < Tom_itx> custom?
2011-11-29T00:48:20 < dekar_> boot linux etc
2011-11-29T00:48:22 < dekar_> yeah
2011-11-29T00:48:28 < Tom_itx> play any game...
2011-11-29T00:48:39 < dekar_> I guess you could play games as well
2011-11-29T00:48:43 < dekar_> don't have any though
2011-11-29T00:48:59 < Tom_itx> so you're just making a linux box out of it?
2011-11-29T00:49:06 < dekar_> I already had a hacked xbox when I got the PS3
2011-11-29T00:49:33 < dekar_> I don't even really need it as linux box, I guess I plan on hacking it out of curiosity
2011-11-29T00:49:41 < dekar_> lack of batter ideas :)
2011-11-29T00:49:45 < dekar_> *better
2011-11-29T00:50:52 < dekar_> and I don't really play on my xbox as well, just sometimes when friends come over - have them jump around playing kinect and having a good laugh :)
2011-11-29T00:55:03 < dekar_> I might try some OpenCL on the PS3
2011-11-29T00:55:30 < dekar_> having 7 cores it should show some nice performance increase when using it properly :)
2011-11-29T00:57:32 < dekar_> Tom_itx, do you like AVR? I started feeling like I know the ARM internals so I really don't feel like switching architectures
2011-11-29T00:59:01 < dekar_> Had to reverse engineer some arm firmware lately and had to write a ton of arm assembly at university, thus I'll probably stick with arm for the rest of my life :)
2011-11-29T01:08:13 < Tom_itx> i've messed with avr a bit
2011-11-29T01:08:37 < Tom_itx> it's alot easier than arm to learn
2011-11-29T01:32:33 < karlp> avrlibc is a lot more mature too

2011-11-29T18:40:34 < Laurenceb> anyone here used NVIC_SystemReset()
2011-11-29T18:45:06 < grummund> yes i believe so
2011-11-29T18:45:53 < Laurenceb> it doesnt seem to be working for me
2011-11-29T18:46:02 < Laurenceb> just halts the processor
2011-11-29T18:46:40 < grummund> maybe an issue with whatever debugger you use
2011-11-29T18:46:49 < Laurenceb> hmm
2011-11-29T18:46:57 < Laurenceb> ill investgate
2011-11-29T18:56:24 < _Shurik_> Guys, what is the reason for Set/Reset port pin register exactly? I can't quite find a good explanation anywhere
2011-11-29T19:07:01 < karlp> for atomic bit acess
2011-11-29T19:07:11 < _Shurik_> How do you mean>
2011-11-29T19:07:12 < _Shurik_> ?
2011-11-29T19:07:15 < karlp> so you don't have to read the whole port, mask and edit the bit you want, and then write it back.
2011-11-29T19:07:25 < karlp> the set/reset is for bitbanding,
2011-11-29T19:07:51 < karlp> so instead of doing the read-modify-write, you write 0 to one place to magically set just a single bit
2011-11-29T19:07:57 < _Shurik_> so what does Set and Reset state actually mean?
2011-11-29T19:08:01 < karlp> 1 and 0
2011-11-29T19:08:12 < _Shurik_> ah, so it's a mask register?
2011-11-29T19:08:32 < _Shurik_> it basically acts as a final bitwise AND?
2011-11-29T19:08:53 < _Shurik_> I see I see
2011-11-29T19:09:00 < _Shurik_> so Set - means writable?
2011-11-29T19:09:03 < _Shurik_> Reset - not?
2011-11-29T19:09:21 < karlp> set sets the bit, reset resets it to 0
2011-11-29T19:09:30 < karlp> writeable doesn't really relate to this
2011-11-29T19:09:42 < _Shurik_> Aaaaaah
2011-11-29T19:09:44 < _Shurik_> jeez
2011-11-29T19:09:46 < _Shurik_> I'm slow
2011-11-29T19:10:15 < _Shurik_> So, instead of addressing PortB at all, by using Set/Reset register you can alter specific bits
2011-11-29T19:10:16 < _Shurik_> okay, I got it
2011-11-29T19:10:27 < _Shurik_> Thank you!
2011-11-29T19:10:49 < _Shurik_> I'm really digging STM32 after messing with AVRs
2011-11-29T19:11:38 < Laurenceb> grummond: yeah nvic reset works now
2011-11-29T19:11:41 < Laurenceb> weird
2011-11-29T19:14:15 < _Shurik_> karlp: is it possible to effect multiple bits via Set/Reset register? I'm trying to figure out why couldn't I blink both LEDs last night :)
2011-11-29T19:16:54 < karlp> not in the same instruction,
2011-11-29T19:17:04 < karlp> those bit banding things are for single bits
2011-11-29T19:17:06 < _Shurik_> Aha!
2011-11-29T19:17:15 < karlp> if you want to do multiple bits, you have to read and modify write
2011-11-29T19:17:16 < _Shurik_> Makes sense now
2011-11-29T19:17:39 < _Shurik_> I see, so you would need to do 1 << 9 and then 1 << 8 for example
2011-11-29T19:17:40 < _Shurik_> got ya
2011-11-29T19:18:10 < karlp> show us the code?
2011-11-29T19:19:16 < karlp> you can do GPIOB_ODR |= (1<<9) | (1<<8);
2011-11-29T19:19:30 < _Shurik_> Yes, that's for a normal port operation
2011-11-29T19:19:58 < _Shurik_> I'm was just trying to figure out what the hell was that port, and you explained me very well - thank you
2011-11-29T19:21:06 < karlp> if you're using GPIOB->BSRRL = blah,
2011-11-29T19:21:20 < karlp> that's only for single bits...
2011-11-29T19:21:39 < _Shurik_> yeah
2011-11-29T19:21:52 < _Shurik_> Well, it is probably useful for serial operations
2011-11-29T19:21:57 < _Shurik_> I haven't gotten that far yet

2011-11-29T23:32:10 < Tom_itx> see all the holes in the middle of the board?
2011-11-29T23:32:15 < Tom_itx> those connect to the other side
2011-11-29T23:32:18 < dekar_> do they have to do that below BGA components to get them connected to different layers?
2011-11-29T23:32:25 < Tom_itx> in this case it's a 2 layer board
2011-11-29T23:32:34 < Tom_itx> absolutely
2011-11-29T23:32:44 < Tom_itx> and bga generally takes multiple layers
2011-11-29T23:32:49 < Tom_itx> due to the density
2011-11-29T23:33:05 < Tom_itx> there are various types of vias
2011-11-29T23:33:09 < dekar_> so they fill them up so you can solder the BGA on top?
2011-11-29T23:33:10 < Tom_itx> some are hidden etc
2011-11-29T23:33:36 < Tom_itx> it depends on the designer how the bga footprint is done
2011-11-29T23:35:18 < Tom_itx> have you ever made a board?
2011-11-29T23:40:15 < dekar_> nope
2011-11-29T23:40:26 < dekar_> will probably do that at one point

2011-11-30T01:47:45 < karlp> I'm using a 32L, which is meant to startup in with the MSI being sysclock.  I've got my own startup code and linker script, which seem to work, and I'm completely leaving out _all_ clock setup,
2011-11-30T01:48:05 < karlp> so I thought I _should_ be getting it to run at ~2Mhz, the default reset range of the MSI
2011-11-30T01:48:13 < karlp> but it seems to still be running on the HSI?
2011-11-30T01:48:41 < karlp> hah, rubber duck effect
2011-11-30T01:48:55 < karlp> seems that simpyl reflashing and swd reset isn't the same as power cycle reset
2011-11-30T01:49:02 < karlp> let's backtrack a few steps...
2011-11-30T01:58:36 < Laurenceb_> yeah thats confused me
2011-11-30T01:59:02 < Laurenceb_> is there a difference between target extended-remote and tar ext in gdb?
2011-11-30T01:59:30 < Laurenceb_> or is that just the same thing?
2011-11-30T01:59:38  * Laurenceb_ is getting confused by gdb tutorials
2011-11-30T02:01:26 < karlp> same thing
2011-11-30T02:01:44 < Laurenceb_> ah
2011-11-30T02:01:53 < Laurenceb_> so it seems reset line isnt supported
2011-11-30T02:02:17 < Laurenceb_> from stlink
2011-11-30T02:02:33 < AK6L> are you guys using github.com/texane/stlink to connect gdb to an st-link based stm32 dev board?
2011-11-30T02:02:44 < AK6L> i'm curious how to do a reset from gdb, too.
2011-11-30T02:03:00 < AK6L> 'monitor reset' doesn't work (but you probably knew that)
2011-11-30T02:03:58 < Laurenceb_> i dont understand monitor at all
2011-11-30T02:04:03 < Laurenceb_> how do you use it?
2011-11-30T02:05:11 < AK6L> Laurenceb_: as i gather, it just passes commands unmolested to the remote target
2011-11-30T02:05:17 < AK6L> in this case, the st-util daemon
2011-11-30T02:05:40 < Laurenceb_> ah
2011-11-30T02:05:46 < Laurenceb_> so what
2011-11-30T02:05:56 < Laurenceb_> monitor <variable>  ?
2011-11-30T02:06:02 < AK6L> i looked at the st-util code and if it gets an 'R' command, it will reset the board
2011-11-30T02:06:17 < AK6L> but all of the 'monitor foo' commands from gdb appear to come through as qCmd,foo or something
2011-11-30T02:06:35 < AK6L> Laurenceb_: i don't think 'monitor' is useful with texane's stlink, is what i'm getting at
2011-11-30T02:07:13 < AK6L> hell, i'll just email the author.
2011-11-30T02:07:31 < Laurenceb_> oh
2011-11-30T02:07:45 < Laurenceb_> i thought monitor changed how gdb handled data
2011-11-30T02:07:58 < Laurenceb_> so it didnt have to halt the processor to read
2011-11-30T02:08:15 < karlp> monitor only works with mine or peabody's current master
2011-11-30T02:08:22 < karlp> it hasn't gone back to texane yet.
2011-11-30T02:08:53 < karlp> monitor reset and monitor resume work in those two branches
2011-11-30T02:09:01 < Laurenceb_> right
2011-11-30T02:09:07 < karlp> kill should do a reset.
2011-11-30T02:09:08 < Laurenceb_> so what does monitor reset do?
2011-11-30T02:09:22 < karlp> I believe that's in the top level readme.
2011-11-30T02:09:26 < Laurenceb_> ok
2011-11-30T02:09:31 < AK6L> karlp: aaaah.
2011-11-30T02:09:32 < karlp> I'm still learning monitor stuff in gdb
2011-11-30T02:09:36 < Laurenceb_> me too
2011-11-30T02:09:43 < AK6L> karlp: does yours work with stlink/v2?
2011-11-30T02:09:47 < Laurenceb_> guess i should shut up and grab my discovery :P
2011-11-30T02:10:00 < AK6L> i'm trying to get a Forth implementation working on an STM32F4 Discovery board.
2011-11-30T02:10:18 < karlp> colour forth? or regular insanity forth?
2011-11-30T02:10:29 < karlp> I have a 32L board, which is stlinkv2, so it should work.
2011-11-30T02:10:39 < karlp> peabody who wrote the monitor stuff has an F4 iirc
2011-11-30T02:10:41 < AK6L> karlp: http://pygmy.utoh.org/riscy/
2011-11-30T02:11:06 < AK6L> that's what i'm trying to 'port', if changing memory address constants can really be said to be a port :)
2011-11-30T02:11:30 < AK6L> karlp: cool, got a URL for your version?
2011-11-30T02:11:42 < karlp> github.com/karlp/stlink
2011-11-30T02:11:53 < AK6L> cool, thanks, i'll try that out this evening.
2011-11-30T02:12:08 < karlp> don't suppose you know much about the startup clocks on these things?
2011-11-30T02:12:18 < karlp> if I explicitly set the HSI clock, it works,
2011-11-30T02:12:38 < karlp> if I don't set any clock, it seems to not do anything, despite allegedly running from the MSI clock if nothing is set
2011-11-30T02:13:00 < AK6L> karlp: my experience with ARM and STM32 extends only to what i've read in the datasheets and programming manuals for this Forth port project :/
2011-11-30T02:16:00 < karlp> have you got the five minute answer for why I should even look at forth?
2011-11-30T02:16:06 < karlp> sorry,
2011-11-30T02:16:17 < karlp> have you got the time to give me a five minute answer why I should look at forth
2011-11-30T02:16:33 < AK6L> heh, sure
2011-11-30T02:16:45 < AK6L> it can be handy to try things out and get immediate feedback
2011-11-30T02:17:27 < AK6L> it lets you build very, very small pieces of code, prove they work, and then build pieces of code that just call those proven-working ones
2011-11-30T02:17:58 < AK6L> it's very simple so it is - in theory - very quick for board bringup
2011-11-30T02:18:22 < AK6L> i'm a hobbyist, not a professional EE, so i've spent longer on this port than someone who really knew what they were doing, would have
2011-11-30T02:19:20 < AK6L> if you ever did PEEK and POKE on an apple ][, and used an HP RPN calculator (and enjoyed it), forth is probably a natural step
2011-11-30T02:19:29 < AK6L> if those things sound awful to you, then it probably isn't :)
2011-11-30T02:20:40 < karlp> fair enough :)
2011-11-30T02:21:10 < AK6L> i enjoy it, and i have a friend who does some embedded work and loves forth so i have help when i need it
2011-11-30T02:21:39 < AK6L> and once the !$!#@ thing is running, it is actually a lot faster to do prototyping than a compile-flash-test cycle with C or whatever

2011-11-30T02:30:26 < karlp> huh, I have to have HSI _on_ but not necessarily in use to be able to use the MSI?
2011-11-30T02:30:32 < karlp> I'm sure somethign else is busted here...
2011-11-30T02:39:11 < karlp> anyone know what I'm likely to be missing here: http://pastebin.com/djMcE2pS
2011-11-30T02:39:34 < karlp> if I turn on the HSI, it boots and runs with the MSI, as configured on line 28
2011-11-30T02:39:53 < karlp> I can later read the clock source registers and blink different things based on the source.
2011-11-30T02:40:10 < karlp> likewise if I change the ifdefs to actually use the HSI, I gget the proper HSI.
2011-11-30T02:40:22 < karlp> but if I don't turn on HSI, it never starts at all.

2011-11-30T04:31:40 < jnosky> I dont think reset works right either
2011-11-30T04:31:56 < jnosky> Its just not the same as pushing the button
2011-11-30T04:32:20 < jnosky> Mine usually hangs in the clk starting up somewhere
2011-11-30T04:33:00 < jnosky> I tried jumping to reset to, same results
2011-11-30T04:33:28 < jnosky> We talking the other day of this, upload new code, and it doesnt allways run
2011-11-30T04:33:46 < jnosky> Wher it runs just fine from a hard POR
2011-11-30T04:34:04 < jnosky> I wonder if theres some jtag that could be dont to correct that
2011-11-30T04:34:38 < Tom_itx> if it's anything like an avr, jumping doesn't reset the registers however a wdt reset would
2011-11-30T04:35:03 < Tom_itx> POR, everything is in a known state
2011-11-30T04:35:19 < Tom_itx> a jmp wouldn't do that
2011-11-30T04:35:39 < jnosky> Well I didnt think it would really work any better, I was just giving it a shot
2011-11-30T04:35:50 < jnosky> Since the stlink reset clearly aint hard enuf
2011-11-30T04:36:25 < jnosky> But since the stlink is just a jtag shell, there should be some kinda better way
2011-11-30T04:37:05 < jnosky> "kill" doesnt seem to be so hard either
2011-11-30T04:37:35 < jnosky> Ive gotten in the habit of just pushing the button after I upload
2011-11-30T04:37:57 < jnosky> But thats not real clean for debugging src in eclipse
2011-11-30T04:39:25 < Tom_itx> are you looking for a software reset?
2011-11-30T04:39:47 < Tom_itx> 5.1.1 says WWDG will do a system reset

2011-11-30T04:40:00 < jnosky> no I wanta reset hard, after I upload new code, by stlink
2011-11-30T04:40:09 < Tom_itx> pulse that pin then
2011-11-30T04:40:18 < jnosky> That might be worth a go

2011-11-30T17:58:28 < AK6L> flashed a simple led blinker program into my stm32f4 discovery board last night a few times, and suddenly it stops being able to write
2011-11-30T18:07:17 < karlp> someoen said they had a mmap file problem once before,
2011-11-30T18:07:21 < karlp> but cleaning and rebuilding should fix it,
2011-11-30T18:07:29 < karlp> it seems to be more of an OS locking on the file than an stlink problem
2011-11-30T18:07:32 < karlp> I've never seen it personally
2011-11-30T18:07:53 < AK6L> hmm, ok.
2011-11-30T18:08:07 < AK6L> not sure that's what this is; seems like a problem talking to the stlink
2011-11-30T18:08:13 < AK6L> or the stlink is having trouble talking to the chip
2011-11-30T18:08:44 < AK6L> (unknown chip id 0)
2011-11-30T18:09:00 < AK6L> but the map file error is interesting, i guess i wasn't paying attention to that
2011-11-30T18:12:53 < karlp> stutil should probably _abort_ rather than attempt to continue if the mmap fails :)
2011-11-30T18:12:56 < karlp> that's more the problem.
2011-11-30T18:13:01 < karlp> are you on windows by anychance?
2011-11-30T18:13:05 < AK6L> ubuntu.
2011-11-30T18:13:16 < AK6L> was going to go try one of ST's windows utilities.
2011-11-30T18:13:33 < karlp> ok, there's a patch in the tree that replaces the mmap with open/read because mmap apparently isn't as portable, even if it somewhat higher performance
2011-11-30T18:14:07 < karlp> unknown chipid is pretty busted too.
2011-11-30T18:14:13 < karlp> especially if it says unlocked flash
2011-11-30T18:14:21 < karlp> it should probably abort if it gets unknown chipid too,
2011-11-30T18:14:28 < karlp> there's no real point in attempting to continue.
2011-11-30T18:14:52 < karlp> you can file them as tickets on texane's github issue list, they'll get looked at by someone.
2011-11-30T18:15:26 < karlp> you shouldn't need sudo for the flash write operation,
2011-11-30T18:15:42 < karlp> well, if you put in the udev rules
2011-11-30T18:16:26 < AK6L> thought udev rules weren't needed for stlink/v2?
2011-11-30T18:16:39 < AK6L> since it's a usb endpoint, not a scsi generic
2011-11-30T18:17:51 < karlp> modprobe rules arne't needed (to tell linux to ignore the scsi device)
2011-11-30T18:18:05 < karlp> but ubuntu at least still restricts user access to usb devices
2011-11-30T18:18:10 < karlp> that's what the udev rules are for.
2011-11-30T18:18:29 < karlp> also, if they weren't needed, you would have needed the sudo you were doing yourself ;)

2011-11-30T21:06:23 < Laurenceb_> so i have to f_sync or something? or close then truncate?
2011-11-30T21:06:35 < Laurenceb_> atm i truncate then close
2011-11-30T21:07:22 < Laurenceb_> "The f_sync function performs the same process as f_close function but the file is left opened"
2011-11-30T21:07:29  * Laurenceb_ is double confused
2011-11-30T21:07:55 < Laurenceb_> i see data thats clearly not correctly synced after i call my close function
2011-11-30T21:15:55 < Laurenceb_> https://github.com/Laurenceb/STM32-Logger/blob/master/Util/fat_fs/src/ff.c#L3886
2011-11-30T21:16:13 < Laurenceb_> ^nice, didnt know it has a printf implementation
2011-11-30T21:16:40 < karlp> it's one of the things you can disable in the config isn't it?
2011-11-30T21:17:25 < Laurenceb_> yeah
2011-11-30T21:17:40 < Laurenceb_> i have my own printf based on pascal stangs code
2011-11-30T21:23:24 < Laurenceb_> hmm looks like im doing it correctly?
2011-11-30T21:23:45 < Laurenceb_> lseek to 1000000, lseek to 0, write data, truncate and close
2011-11-30T21:24:02 < Laurenceb_> maybe truncate followed by close is wrong?
2011-11-30T21:24:11 < Laurenceb_> should i sync, truncate, then close?
2011-11-30T21:24:43 < Laurenceb_> atm my file is missing the last data, and is truncated to 1000000
2011-11-30T22:13:05 <+Steffanx> Are you using spi btw?
2011-11-30T22:13:13 <+Steffanx> Or the dedicated sd interface?
