2011-12-01T00:35:03 < karlp> well, I worked out why I couldn't seem to boot without the HSI last night.
2011-12-01T00:35:12 < karlp> I thought for sure it should be able to run on the MSI.
2011-12-01T00:35:25 < karlp> it can, but closer inspection of the clock tree showed that the ADC _must_ run off the HSI.
2011-12-01T00:35:41 < karlp> and my little test program was using the ADC; and blocking in ADC init
2011-12-01T00:35:47 < karlp> so, it was running.
2011-12-01T00:35:48 < karlp> bleh.
2011-12-01T00:35:51 < karlp> anyway, good to know :)
2011-12-01T00:36:26 < Laurenceb_> karlp: i probably asked before, but ever used seek on fatfs?
2011-12-01T00:36:30 < Laurenceb_>  :P
2011-12-01T00:41:43 < karlp> no, sorry
2011-12-01T00:41:50 < karlp> I just opened, wrote, and closed,
2011-12-01T00:42:03 < karlp> why do you need to call truncate?
2011-12-01T00:42:21 < karlp> is this because you're seeking forwards to "preallocate" the file?
2011-12-01T00:42:24 < Laurenceb_> its supposed to speed up seek
2011-12-01T00:42:26 < Laurenceb_> yes
2011-12-01T00:42:35 < Laurenceb_> s/seek/write
2011-12-01T00:42:46 < karlp> does it actually speed it up?
2011-12-01T00:42:53 < karlp> I mean, was it working, but slow before?
2011-12-01T00:42:59 < karlp> and now it sometimes loses the last write?
2011-12-01T00:43:10 < Laurenceb_> according to someone on another channel is does
2011-12-01T00:43:32 < Laurenceb_> apparently on most cards it dramatically reduces the probability of a long block from the card
2011-12-01T00:43:40 < Laurenceb_> as in card blocking for hundereds of ms
2011-12-01T00:45:25 < karlp> hmm. do you know why the system_stm32xxxx code does this?     RCC->APB1ENR |= RCC_APB1ENR_PWREN;
2011-12-01T00:45:33 < karlp> the power regulator is definitely on,
2011-12-01T00:45:47 < karlp> is that meant to be just enabling the clocks to the power management interface,
2011-12-01T00:46:05 < karlp> so that you have to do that before you can write to the PWR registers and have them take any effect?
2011-12-01T00:51:59 < Laurenceb_> seems to ring a bell to me
2011-12-01T00:52:19 < Laurenceb_> everything seems to have controllable clk on stm :P
2011-12-01T00:54:06 < karlp> hmm, looks like by default it powers up in range 2, not range 1.
2011-12-01T00:54:20 < karlp> man, I wish the register diagrams had a row that showed the reset state for each bit,
2011-12-01T00:54:40 < karlp> not just a "0x00b0c300" word for the register reset state
2011-12-01T00:57:51 < karlp> ahh, the register map giant infograph that is after the individual register descriptions has that.
2011-12-01T00:58:40 < Laurenceb_> any ideas what the "top of file" is?
2011-12-01T01:06:19 < Laurenceb_> ooh maybe i bounced to on/off switch
2011-12-01T01:06:26 < Laurenceb_> *bounced the
2011-12-01T01:07:00 < Laurenceb_> might explain why my logfile is screwed

2011-12-01T02:59:03 < karlp> heh, ST's microXplorer installed ok in wine, but then wants java to run :)
2011-12-01T03:03:48 < karlp> hmm, I've forgotten all my java tricks to set the class path properly...
2011-12-01T03:05:23 < AK6L> heh
2011-12-01T03:05:34 < AK6L> the ST-LINK/V2 utility installs fine under Windows 7
2011-12-01T03:05:40 < AK6L> but right before the installer quits it chokes on something
2011-12-01T03:05:43 < AK6L> and uninstalls itself.
2011-12-01T03:06:01 < AK6L> i got it to work by just leaving the error dialog up and running the utility.
2011-12-01T03:06:02 < karlp> you mean the ST provided util for it?
2011-12-01T03:06:05 < AK6L> yeah.
2011-12-01T03:06:21 < AK6L> that utility fixed my STM32F4 Discovery board, as I figured it would
2011-12-01T03:06:35 < karlp> heh, this microXplorer looks really neat, letting you choose what periphs you want, and it searchs the available pin mappings for you
2011-12-01T03:06:42 < AK6L> nice
2011-12-01T03:06:48 < karlp> unplugging and replugging in linux didn't resurrect it for you?
2011-12-01T03:06:54 < AK6L> karlp: nope.
2011-12-01T03:07:18 < AK6L> i suspect there might be a bug in st-util or flash
2011-12-01T03:07:44 < karlp> I don't think this tool had much QA though, it has a "db/DbDesigner-test" directory in the jar, full of excel spreadsheets
2011-12-01T03:07:56 < AK6L> karlp: kwality!
2011-12-01T03:08:27 < karlp> the jar runs ok and makes windows properly on linux, but someone broke the class path somewhere, so it can't find the db files
2011-12-01T03:09:04 < karlp> seems to only be for f105, f107 and 205, 207 anyway
2011-12-01T03:09:10 < karlp> still, might be interesting in the future.
2011-12-01T03:09:13  * karlp shelves it
2011-12-01T03:13:04 < karlp> has anyone seen an actual ST download location for this clock configuration tool excel sheet they keep referring to in the system_stm32xxxxxx.c files?

2011-12-01T04:09:58 < karlp> jnosky: you're a legend, why couldn't I find that earlier?
2011-12-01T04:10:37 < jnosky> I came across it just the other day myself
2011-12-01T04:11:12 < jnosky> Ive not tried it tho, im leary of messing with clocks at this point
2011-12-01T04:11:34 < jnosky> Im not real fluent in the startup procedure
2011-12-01T04:12:29 < Tom_itx> why is stuff so hard to find on st anyway?
2011-12-01T04:13:34 < jnosky> Theres just too much stuff
2011-12-01T04:14:11 < jnosky> Hard to believe the programmer has to start up the clocks
2011-12-01T04:14:13 < jnosky> :P
2011-12-01T04:14:31 < jnosky> But the tdmi was the same way i suppose
2011-12-01T04:14:41 < jnosky> you had to "feed" the pll or some shit
2011-12-01T04:14:52 < jnosky> I allways ignored it, used tha canned code
2011-12-01T04:14:57 < Tom_itx> with a pull rope?
2011-12-01T04:15:00 < karlp> I've just spent the last two days learning about the clocks :)
2011-12-01T04:15:01 < jnosky> I was hoping to do the same here
2011-12-01T04:15:23 < karlp> long and short, you can not do anything at all, and it will just run ok for many purposes.
2011-12-01T04:15:27 < jnosky> Well im its sure a good thing to know about ;)
2011-12-01T04:15:41 < karlp> the system_stmXXXXX files do a hell of a lot that is arguably redundant.
2011-12-01T04:15:42 < jnosky> After all it is... well... the clock and all :)
2011-12-01T04:15:54 < karlp> I'm just polishing up commits and test code in my repo.
2011-12-01T04:16:13 < karlp> I've replaced these atollic non-redistributable linker scripts in a few places too.
2011-12-01T04:16:34 < karlp> I kinda think the ./examples/* tree needs to be chopped out of the stlink repo though.
2011-12-01T04:17:03 < jnosky> I kinda made my own example repo
2011-12-01T04:17:15 < jnosky> That stuff doesnt really belong in stlink
2011-12-01T04:17:16 < karlp> I've got a working plain C startup file, simpler linker scripts, so you only have to define the top "memory map" portion
2011-12-01T04:17:20 < karlp> yeah, exactly.
2011-12-01T04:17:27 < karlp> I've been working in stlink just because it was convenient
2011-12-01T04:17:59 < karlp> but I think I want to chop out all of it except a very very basic blink example, just to help verify that the tool works, without having to get/build more tools
2011-12-01T04:18:17 < karlp> so....
2011-12-01T04:18:21 < jnosky> I just noticed those attolic warnings in example repo as well
2011-12-01T04:18:37 < jnosky> I wonder if they send me a nasty-gram
2011-12-01T04:18:39 < karlp> anyone enough of a git master to know how to take a sub directory from one repo, and make it a whole new repo, keeping history?
2011-12-01T04:19:06 < karlp> I actually noticed the atollic stuff when texane first added a demo containing them.
2011-12-01T04:19:15 < jnosky> Well I say fuck em
2011-12-01T04:19:18 < karlp> it came from ST though, in their downloads
2011-12-01T04:19:29 < jnosky> They are riding on the back of eclipse
2011-12-01T04:19:37 < jnosky> Ya exactly
2011-12-01T04:19:54 < jnosky> Like most of the crap came from st
2011-12-01T04:20:56 < karlp> I reckon ST went to the tools vendors and said, "provide us some project files to go with these examples"
2011-12-01T04:21:19 < karlp> it's probably not unreasonable that ST could distribute a single zip with project configs for various commercial ides?
2011-12-01T04:21:22  * karlp shrugs
2011-12-01T04:21:25 < jnosky> tool vendors
2011-12-01T04:21:27 < jnosky> bah :P
2011-12-01T04:21:34 < karlp> anyway, I'm removing them from the stlink repo
2011-12-01T04:21:34 < jnosky> Tool repackagers
2011-12-01T04:21:48 < karlp> I've also learnt a hell of a lot about shit I never really meant to learn about
2011-12-01T04:21:59 < karlp> well, RIDE's startup and linker scripts are "free to use"
2011-12-01T04:22:07 < karlp> and ride are gcc guys
2011-12-01T04:22:14 < jnosky> attolic uses st startup code
2011-12-01T04:22:25 < karlp> it's atollic that has a "only use this with atollic tools" license

2011-12-01T04:23:06 < karlp> I used atollic for about 30 minutes to verify that my board still worked, back in the bad old days when stlink tools still claimed that the blink examples "worked"
2011-12-01T04:23:13 < jnosky> How come they can make and sell plugins for eclipse anyway?
2011-12-01T04:23:22 < karlp> why not?
2011-12-01T04:23:31 < jnosky> Well eclipse is open src
2011-12-01T04:23:48 < jnosky> All the other plug ins are free, annd open, that i have ever seen
2011-12-01T04:23:58 < karlp> hahaha
2011-12-01T04:24:08 < karlp> there's hundreds of companys that use eclipse as the gui :)
2011-12-01T04:24:27 < karlp> I don't normally mind, it's normally pretty apparent which ones actually care, and which ones don't
2011-12-01T04:24:42 < karlp> the litmus test is, "can I install your tool as a feature into my existing eclipse installation"
2011-12-01T04:24:54 < karlp> vs "you must use this complete package preconfigured"
2011-12-01T04:25:00 < jnosky> All thier plug in does is hide the make files
2011-12-01T04:25:52 < karlp> hehe: "This tool runs on STM32L1xx Ultra Low Power Medium-Density Devices"
2011-12-01T04:25:58 < karlp> it's talking about a .xls :)
2011-12-01T04:27:01 < jnosky> Oh you cnat run excell on yer L1?
2011-12-01T04:27:04 < jnosky> pity
2011-12-01T04:29:32 < karlp> that link you sent, it has clock config tools for L1, F2, and F4.  have you seen one for F1?
2011-12-01T04:30:14 < karlp> oh, it was pretty clear tonight reading the clock ssection for the F10Yxx, the F100xx, the L1, F2 and F4, that the F10Yxx is definitely an older chip.
2011-12-01T04:30:36 < karlp> it's pretty clearly their first step into the M3 chips

2011-12-01T06:32:02 < joe9> is anyone aware of any stm device for a usb low speed device? I see the full speed device STM32F103, but curious, if there is a device with the low speed peripheral.
2011-12-01T07:34:01 < joe9> Hello, I am just starting with the stm32. I read from the spec that the HSI clock -> PLL -> USB clock. I am assuming that HSI = High Speed Internal Clock (RC) and does not need any external crystal.
2011-12-01T07:34:05 < joe9> Is that correct?
2011-12-01T07:34:33 < joe9> Can i use the USB peripheral (Full Speed Device mode of operation only) without an external crystal?
2011-12-01T07:40:57 < joe9> found this article: http://docs.google.com/viewer?a=v&q=cache:8fuN8VE9CFsJ:www.icbank.com/Forum/ST/board/upload/STM32F10x_Seminar_9_18_ppt.pdf+stm32F103+usb+clock&hl=en&gl=us&pid=bl&srcid=ADGEESjkimDSmnbu-EDbfHqJPvkrsxpnskZr-qklrcZyZJm76xntkg_Ia-gxp2oGPeV9FXJkxfpv7Mn4E1olJ5L0j8LjnkdXH8w6vMOgtKSQ6fYFCRqYu05ebOHV_Q0B2IaAA8KNsxI3&sig=AHIEtbQgZ5lOCvU0v01GIBJ2qmW436C-HA
2011-12-01T07:41:08 < joe9> which says that i can use HSI to run the USB Clock.
2011-12-01T07:41:18 < joe9> Is that a bad idea? any experiences?

2011-12-01T13:32:02 < Laurenceb> this is my job
2011-12-01T13:32:17 < Laurenceb> arm dev
2011-12-01T13:32:52 <+Steffanx> Self-employed ?
2011-12-01T13:34:16 < Laurenceb> its complicated :P
2011-12-01T13:35:14 <+Steffanx> Freelance ?
2011-12-01T13:35:20 <+Steffanx> How can something like that be complicated?
2011-12-01T13:35:34 < Laurenceb> im doing a commercially sponsored PhD atm
2011-12-01T13:35:52 < BrainDamage> professional IRCer ?
2011-12-01T13:36:08 <+Steffanx> Ah, lol :P
2011-12-01T13:45:50 < karlp> I am at work too.
2011-12-01T13:46:18 <+Steffanx> Oh, your boss doesn't care (or doesn't even know)? L)
2011-12-01T13:46:26 < karlp> stm32 isn't directly work related, but I'm collecting ideas for future hardware.
2011-12-01T13:46:37 < karlp> I'm not always sitting here staring at irc :)
2011-12-01T13:47:22 < karlp> boss knows I talk to people online outside thecompany, and they often help me with my work problems.
2011-12-01T13:47:26 < karlp> as I (try) to help them.
2011-12-01T13:47:36 < karlp> this is perfectly acceptable to work :)
2011-12-01T13:48:22 < karlp> I do then go home and irc with the same nick, and chat about topics that overlap with work.
2011-12-01T13:48:29 < karlp> what about you? you're here a lot too.
2011-12-01T13:48:39 <+Steffanx> Uhm, I only work 3 days/week
2011-12-01T13:48:59 <+Steffanx> Just finished my study and I don't want to work 40 hours/week yet :P
2011-12-01T13:50:35 < karlp> hehe.
2011-12-01T13:50:39 < karlp> I can understand that.
2011-12-01T13:50:50 < karlp> I used to work 90%, four days one week, 5 the other. loved it
2011-12-01T13:51:08 < karlp> started a new job though, and we're a little understaffed,
2011-12-01T13:51:16 <+Steffanx> I want to go for my master next year anyway :)
2011-12-01T13:51:28 < karlp> saying, "yeah, I don't really want to work much" when I actually do love my day job (now) wouldn't really work. (yet)
2011-12-01T13:51:41 < karlp> I want to go back to 90% or less in the future again though
2011-12-01T13:52:20 <+Steffanx> I learn a lot from my hobby-bobby projects so it's good for my boss too :P
2011-12-01T13:52:25 < Laurenceb> any idea why fatfs capitalises filenames?
2011-12-01T13:56:32 < karlp> because old fat only had capitals
2011-12-01T13:56:37 < karlp> or, more correctly,
2011-12-01T13:56:42 < karlp> because fat is case insensitive
2011-12-01T13:56:56 < karlp> what do you do for the three days?
2011-12-01T13:58:05 < Laurenceb> hmm
2011-12-01T13:58:15 < Laurenceb> is there some config somewhere i need to change?
2011-12-01T14:00:43 < Laurenceb> use unicode?
2011-12-01T14:01:28 <+Steffanx> Long file names..
2011-12-01T14:01:43 < Laurenceb> oh
2011-12-01T14:01:48 < karlp> fat is still intrinsically case insensitive
2011-12-01T14:02:03 < karlp> you can probably chage the fatfs code to not capitalize if that's important foryou
2011-12-01T14:03:40 <+Steffanx> FatFS supports long file names?
2011-12-01T14:04:37 < karlp> yep, in the config somewhere
2011-12-01T14:09:21 < Laurenceb> why does make not detect that i have deleted a file?
2011-12-01T14:09:36 < Laurenceb> i delete a c file and try make clean, make
2011-12-01T14:09:43 < Laurenceb> and it still tries to compile the file
2011-12-01T14:10:49 < Laurenceb> oh i need sync
2011-12-01T14:10:51 < Laurenceb> weird
2011-12-01T14:12:58 <+Steffanx> Life is weird
2011-12-01T14:20:37 < Laurenceb> oh shit
2011-12-01T14:20:41 < Laurenceb> 130248 bytes
2011-12-01T14:28:02 < Laurenceb> ah TINY_TABLE helps - still 71560bytes
2011-12-01T14:28:18 < Laurenceb> unicode support seems to be needed for long file name :(
2011-12-01T14:29:19 < BrainDamage> there's probably some lightweight utf-8 libs
2011-12-01T14:32:48 < Laurenceb> i have 128KB so *shrug*
2011-12-01T15:07:00 < joe9> anyone using usb functionality on the STM32? did you use the internal RC oscillator (HSI) for the USB clock? I am wondering if I can get away without using an external crystal.
2011-12-01T15:07:11 <+Steffanx> Ask Laurenceb joe9
2011-12-01T15:08:07 < joe9> Laurenceb: any thoughts on using the internal RC oscillator for the USB clock? The spec (STM32F103R6) seems to  think that it is theoretically possible to do so. But, am not sure of the practical implications.
2011-12-01T15:08:14 < joe9> Steffanx: thanks.
2011-12-01T15:11:39 < Laurenceb> joe9: should work
2011-12-01T15:11:57 < Laurenceb> it needs to be clked up to 48mhz for the usb core iirc
2011-12-01T15:12:12 < Laurenceb> im using 72mhz with external 12mhz xtal and pll
2011-12-01T15:13:30 < joe9> Laurenceb: Thanks a lot.

2011-12-01T15:16:41 < joe9> Laurenceb: Why are you using an SD card and not an Eeprom? Was that a requirement? Eeprom's are easier to interface, aren't they?
2011-12-01T15:16:59 < Laurenceb> yes
2011-12-01T15:17:05 < Laurenceb> but i need lots of storage
2011-12-01T15:17:14 < Laurenceb> a few GB
2011-12-01T15:18:53 < joe9> oh, ok. thanks.
2011-12-01T15:26:17 < joe9> is it easier to hack/reverse engineer a device with an SD card?
2011-12-01T15:26:43 < jpa-> easier than what?
2011-12-01T15:26:58 < joe9> just curious, have never used one? but, it would probably easy to do something and read it on some other SD card reader and figure out the differences.
2011-12-01T15:27:08 < joe9> easier than using an internal eeprom
2011-12-01T15:28:21 < jpa-> sd cards are quite easy to interface without any reverse engineering
2011-12-01T15:28:57 < joe9> no, reverse-engineering the device using the SD-card, I meant.
2011-12-01T15:29:11 < joe9> no, reverse-engineering the functionality of the device using the SD-card, I meant.
2011-12-01T15:29:41 < jpa-> depends on what the functionality is :D
2011-12-01T15:30:51 < joe9> jpa-: fair enough.

2011-12-01T19:20:01 < Laurenceb> looks like usb hub leads to a lot of overhead or something
2011-12-01T19:20:08 < Laurenceb> or it was just a slow hub
2011-12-01T19:22:39 < karlp> hehe, what's that, 50% or so speedup?
2011-12-01T19:22:47 <+Steffann> +400kbps
2011-12-01T19:23:17 < karlp> he was getting 600 before though right?
2011-12-01T19:23:25 <+Steffann> So, Yes
2011-12-01T19:23:32 <+Steffann> So, not it's 400 extra :)

2011-12-01T19:51:36 < tunilame> I'm making a tutorial, to explain what karlp did last time for me to make my stm32l-discovery work with 32l-dac and 32l-lcd
2011-12-01T19:51:47 < tunilame> I had an error while doing everything from zero:
2011-12-01T19:53:24 < karlp> hello again tunilame, welcome back
2011-12-01T19:53:46 < tunilame> while making the 32l_dac, I had this error: /home/tunilame/sat/lib/gcc/arm-none-eabi/4.5.2/../../../../arm-none-eabi/bin/ld: cannot find -lstm32_stdperiph_l1xx
2011-12-01T19:53:46 < tunilame> thanks :D
2011-12-01T19:53:59 < tunilame> I think it's a permission problem, I'll verify it
2011-12-01T19:54:03 < karlp> no,
2011-12-01T19:54:15 < karlp> that's the "make -C ../libs_stm/build" step again
2011-12-01T19:54:19 < tunilame> I installed the toolchain with sudo
2011-12-01T19:54:22 < tunilame> aha
2011-12-01T19:54:33 < tunilame> thanks again!
2011-12-01T19:54:33 < tunilame> I forget :(
2011-12-01T19:54:38 < karlp> not a problem :)
2011-12-01T19:55:18 < tunilame> the tutorial will be in french (at first), it'll be translated to english then
2011-12-01T19:55:23 < karlp> also, figures, now that work's ready to order parts again, I've convinced them to order from mouser, (by doing the leg work to find cheaper suitable parts) so that I could by 802.15.4 modules (which digikey won't ship to iceland)
2011-12-01T19:55:31 < karlp> and now, mouser's out of stock of the bloody things
2011-12-01T19:55:38 < karlp> 2500 on order :(
2011-12-01T19:57:30 < karlp> quick, what else should I get from mouser?
2011-12-01T19:57:41 < karlp> do they sell whiskey?
2011-12-01T19:58:31 < karlp> tunilame: you can feel very free to edit https://github.com/texane/stlink/blob/master/doc/tutorial/tutorial.tex if you want :)
2011-12-01T19:59:46 < tunilame> @karlp: it's latex? or what?
2011-12-01T20:01:40 < karlp> yeah, something texane wrote
2011-12-01T20:02:01 < karlp> I edited it once, but I haven't really gone over the whole thing and re-edited it in a while.
2011-12-01T20:09:48 < tunilame> ok, I never used it, it's time to learn it :)
2011-12-01T20:10:14 < tunilame> I'll edit it as soon as possible (I need to finish my little tutorial first)
2011-12-01T20:11:49 < karlp> I'd never used it much either, but I figured I could edit the text pretty well, and follow what was set up.
2011-12-01T20:12:01 < karlp> then you just type "pdflatex tutorial.tex"

2011-12-01T20:49:13 < joe9> hello, anyone used the newlib or libopencm3 on a stm32? Can you use those libraries in a commercial product?
2011-12-01T21:08:55 < jpa-> as long as you comply with the license :P
2011-12-01T21:10:18 < jpa-> newlib seems to be GPL mostly
2011-12-01T21:15:04 < joe9> or, are there any other better C libraries for STM32?
2011-12-01T21:15:14 < joe9> jpa-: which library do you use?
2011-12-01T21:15:33 < jpa-> klibc (stripped down version of it)
2011-12-01T21:15:44 < joe9> uclibc seems to be pretty popular too.
2011-12-01T21:15:56 < joe9> jpa-: any particular reason that you went with klibc?
2011-12-01T21:16:13 < jpa-> uclibc is only for linux IIRC
2011-12-01T21:16:21 < jpa-> it was the smallest one i found
2011-12-01T21:16:58 < jpa-> http://essentialscrap.com/boat/libraries.html
2011-12-01T21:18:12 < joe9> jpa-: ok, thanks.
2011-12-01T21:18:48 < jpa-> we checked around with ben1066 just a few days ago, it seems that the files I have used from klibc are actually not under GPL
2011-12-01T21:19:03 < jpa-> so if one were brave, he could drop the GPL licensing if not using tinyprintf
2011-12-01T21:21:18 < joe9> jpa-: i am targeting the stm32f103r6 (32 KB of flash).  For that purpose, the options are either Baselibc or klibc, it appears, from that url. Do you agree?
2011-12-01T21:21:44 < joe9> looks like newlib cannot even be used for that device.
2011-12-01T21:22:08 < jpa-> well it all depends on what functions you need
2011-12-01T21:22:12 < joe9> have you tried libopencm3?
2011-12-01T21:22:37 < jpa-> it does not address the same problem
2011-12-01T21:22:49 < jpa-> but no, i have not used it
2011-12-01T21:23:08 < jpa-> baselibc compiles to 4kB if you include all the functions (but it doesn't implement very many)
2011-12-01T21:23:16 < joe9> oh, ok.
2011-12-01T21:23:37 < jpa-> sometimes you can do without any libc
2011-12-01T21:24:30 < joe9> good to know. for a newbie like me, which library would you recommend starting off with?
2011-12-01T21:24:41 < jpa-> what do you want to do?
2011-12-01T21:25:10 < joe9> usb connectivity with an spi communication with a eeprom and some adc stuff.
2011-12-01T21:25:21 < joe9> usb connectivity, spi communication with a eeprom and some adc stuff.
2011-12-01T21:25:31 < joe9> i meant an external eeprom.
2011-12-01T21:26:09 < jpa-> libc probably isn't very important for that, you would only need it for some debug printfs probably
2011-12-01T21:26:41 < joe9> i currently have that functionality in a pic and I do not use any C library for that.
2011-12-01T21:26:44 < jpa-> libopencm3 may or may not make your job easier; i might recommend chibios because it is quite easy to use and the latest development versions even have some USB stuff

2011-12-01T21:27:16 < jpa-> well libc does not help for that
2011-12-01T21:27:24 < jpa-> i don't know if libopencm3 has anything
2011-12-01T21:27:40 < jpa-> chibios has some SPI code
2011-12-01T21:27:56 < joe9> i remember that while compiling C, it needed memmove and I just coded that function manually.
2011-12-01T21:28:24 < jpa-> true
2011-12-01T21:28:37 < joe9> libc could help with something like that. I do not need anything fancy. something to have when I need it.
2011-12-01T21:28:43 < jpa-> baselibc is also fine for memmove etc. simple functions
2011-12-01T21:28:55 < joe9> ok, cool. thanks .
2011-12-01T21:29:04 < jpa-> newlib should be ok too, memmove is probably very tiny in newlib also
2011-12-01T21:29:33 < jpa-> but considering that newlib is gpl, it may be out of question for you
2011-12-01T21:30:04 < joe9> i am not planning on selling the software. the software would probably be closed-source, but, hoping on selling the product.
2011-12-01T21:31:01 < jpa-> you must give out the source code if you sell a device with GPL code inside it
2011-12-01T21:31:29 < joe9> oh, ok. Isn't arm-gcc gpl code then?
2011-12-01T21:33:47 < jpa-> the compiler is, but the code it produces is not
2011-12-01T21:34:11 < joe9> oh, ok. so, the compiler can be used to produce the software of a commercial product.
2011-12-01T21:34:17 < joe9> got it. thanks.
2011-12-01T21:34:30 < jpa-> yeah
2011-12-01T21:36:15 < joe9> looks like that removes baselibc, klibc and newlib for my needs.

2011-12-01T21:37:31 < jpa-> but as i said, it is probable that baselibc is not covered by gpl after all
2011-12-01T21:37:36 < jpa-> i just haven't verified it
2011-12-01T21:38:51 < joe9> just checked it, it inherits the license of klibc

2011-12-01T21:41:15 < jpa-> eh :)
2011-12-01T21:42:09 <+Steffanx> That nanopb looks nice jpa-
2011-12-01T21:42:20 < jpa-> i am the guy who forked klibc to create baselibc, and klibc is partly GPL and partly BSD and partly public domain
2011-12-01T21:42:39 < jpa-> but they don't give a clear identification of which file is which
2011-12-01T21:42:53 < jpa-> so it is difficult to be sure if baselibc includes any gpl code or not
2011-12-01T21:43:06 < jpa-> Steffanx: it has gained some users :)
2011-12-01T21:43:11 < joe9> jpa-: oh, really. Hats off to you.. Sorry about the confusion.
2011-12-01T21:43:15 <+Steffanx> some = ?

2011-12-01T21:44:00 < jpa-> (and i haven't even got around to using it myself yet :D
2011-12-01T21:44:40 <+Steffanx> lol
2011-12-01T21:44:48 < jpa-> actually, 5; not sure if everyone of them is using it though

2011-12-03T05:37:17 < karlp> at reset, the stack poitner gets loaded in from 0, or sram with the boot pin,

2011-12-03T16:45:17 < dekar> Steffanx, hey my product bricked hardware worth 15k? :/
2011-12-03T16:45:42 <+Steffanx> LOLOL?
2011-12-03T16:46:17 < dekar> trying to unbrick optical transceivers now
2011-12-03T16:46:40 < dekar> they're only half bricked, laser doesn't turn on anymore and they act weird
2011-12-03T16:46:41 <+Steffanx> You shouldn't work on saturday :)
2011-12-03T16:46:47 < dekar> probably firmware corruption -.-
2011-12-03T16:46:57 < dekar> that happened 2 days ago

2011-12-03T16:47:33 < dekar> Well I reverse engineered their firmware update method
2011-12-03T16:47:38 < dekar> must have broken something

2011-12-03T16:48:37 <+Steffanx> What's your 'product' btw?
2011-12-03T16:48:47 < dekar> flexBox2
2011-12-03T16:48:59 < dekar> universal transceiver hacking hardware :)

2011-12-03T16:50:23 <+Steffanx> You have Illustrator skills dekar ?
2011-12-03T16:50:46 < dekar> like for that adobe software? nope
2011-12-03T16:50:51 <+Steffanx> Yes, that sw
2011-12-03T16:51:27 < dekar> that's vector graphics software?
2011-12-03T16:51:31 < dekar> I used inkscape once
2011-12-03T16:51:36 < dekar> was quite nice
2011-12-03T16:51:48 <+Steffanx> inkscape sucks on os x
2011-12-03T16:53:07 < dekar> Steffanx, http://dekar.wc3edit.net/eel_logo.png
2011-12-03T16:53:13 < dekar> made that in inkscape
2011-12-03T16:53:23 < dekar> I liked using it on debian
2011-12-03T16:53:35 < dekar> open office sucks on OSX as well
2011-12-03T16:53:39 < dekar> tons of rendering bugs
2011-12-03T16:54:02 <+Steffanx> I have to make something for a laser cutter, in Excel or look-a-like it's very easy, but it then it's not a vector drawing
2011-12-03T16:54:41 <+Steffanx> I can export it as PDF and import it, but then it's pretty hard to edit it
2011-12-03T16:54:41 < dekar> make it in excel, laser cut it, scan it and vectorize it :D
2011-12-03T16:55:13 < dekar> dunno, try to tell inkscape to vectorize it from your pdf
2011-12-03T16:55:24 < dekar> or that adobe thing
2011-12-03T16:55:31 < dekar> adobe stuff is sooo expensive
2011-12-03T16:55:41 <+Steffanx> Illustrator even recognizes the font/characters
2011-12-03T16:55:51 < dekar> we have all of that at the company and it was like 4k? iirc
2011-12-03T16:55:57 <+Steffanx> but puts everything in a separate layer
2011-12-03T16:56:02 <+Steffanx> It's very expensive yes
2011-12-03T16:56:15 <+Steffanx> And ofcourse i paid for it :P
2011-12-03T16:56:28 < dekar> and since I don't really need it I rather stay away :P
2011-12-03T16:56:35 < dekar> pirate bay license -.-"
2011-12-03T16:56:45 < dekar> I don't really feel like pirating stuff
2011-12-03T16:57:06 <+Steffanx> Me neither, but sometimes i have no choice
2011-12-03T16:57:08 < dekar> wouldn't do that for work related stuff
2011-12-03T16:57:52 <+Steffanx> It's pay, use a 'pirate bay' license or use the crappy open source alternative :(
2011-12-03T16:57:57 < dekar> on the other hand I can just buy any sw I need for work anyway
2011-12-03T16:58:09 <+Steffanx> This is not work related anyway
2011-12-03T16:58:13 < dekar> Hey, don't offend my eel
2011-12-03T16:58:14 <+Steffanx> It's for a hobby bobby project
2011-12-03T16:58:26 < dekar> he's proud of his origin
2011-12-03T16:58:40 <+Steffanx> Huh?
2011-12-03T16:59:01 < dekar> you called inkscape a crappy open source alternative
2011-12-03T16:59:11 <+Steffanx> Yeah
2011-12-03T16:59:19 < dekar> and I really liked it when I made that eel
2011-12-03T16:59:20 <+Steffanx> It can't import the pdf :P
2011-12-03T16:59:33 < dekar> make a screenshot :P
2011-12-03T16:59:33 < dekar> XD
2011-12-03T16:59:50 <+Steffanx> I didn't say you can't make nice things with crappy sw :)
2011-12-03T17:00:09 <+Steffanx> Where's that eel used for?
2011-12-03T17:00:15 < dekar> nothing
2011-12-03T17:00:22 < dekar> I was planning to use it for a project
2011-12-03T17:00:58 < dekar> he's Cutie the electrocuting eel :)
2011-12-03T17:05:50 <+Steffanx> :)

2011-12-03T17:08:24 < dekar> dunno, that's not too bad either
2011-12-03T17:08:34 < dekar> I actually like my eel :)

2011-12-04T20:33:06 < Laurenceb_> ref manual p250
2011-12-04T20:35:58 < karlp> which ref manual?
2011-12-04T20:36:39 < karlp> RM0008 :)

2011-12-04T21:16:25 < Laurenceb_> theres hardware quadrature encoder support as well
2011-12-04T21:19:55 < karlp> do you know what the difference is between events and interrupts?
2011-12-04T21:21:36 < Laurenceb_> events are internal signals aiui
2011-12-04T21:22:39 < Laurenceb_> for e.g. setting up the adc
2011-12-04T21:23:02 < Laurenceb_> xmega avr took that idea to the extreme
2011-12-04T21:26:13 <+Steffanx> 'extreme' Laurenceb .. ?
2011-12-04T21:26:34 <+Steffanx> It's like all manufacturers should do it
2011-12-04T21:26:55 <+Steffanx> + how (somewhere in that sentence)
2011-12-04T21:28:47 < karlp> I'm not sure I understand.
2011-12-04T21:28:56 < karlp> like in the EXTI section of the ref manual, it says things like this: An interrupt/event request can also be generated by software by writing a ‘1’ in the software
2011-12-04T21:29:00 < karlp> interrupt/event register.
2011-12-04T21:29:10 < karlp> most of that chapter seems to make them out as interchangeable words.
2011-12-04T21:29:20 < karlp> Is there some other difference?
2011-12-04T21:38:11 < Laurenceb_> hmm
2011-12-04T21:38:46 < karlp> or is just that some people use interrupt to mean things on external lines and event for things inside the chip?
2011-12-04T21:51:09 < Laurenceb_> maybe
2011-12-04T21:51:23 < Laurenceb_> they always talk about event for things to trigger the adc for example
2011-12-04T21:51:37 < Laurenceb_> but then those are usually internally generated

2011-12-04T22:52:48 < Laurenceb_> dont know
2011-12-04T22:53:03 < Laurenceb_> is there a simple helper function to set the pwm duty cycle?
2011-12-04T22:53:07 < Laurenceb_> in the perif lib
2011-12-04T22:54:37 < Tom_itx> what were you talking about that had hardware quadrature?
2011-12-04T22:57:45 < Laurenceb_> F1
2011-12-04T22:58:27 < Tom_itx> oh
2011-12-04T22:59:46 < jpa-> Laurenceb_: the duty cycle is just one register anyway, what is hard about that?
2011-12-04T22:59:54 < Laurenceb_> heh
2011-12-04T23:04:49 < Laurenceb_> the auto reload register?
2011-12-04T23:05:31 < Tom_itx> are the F1 peripherals more for automotive?
2011-12-04T23:05:36 < Tom_itx> or motion control...
2011-12-04T23:05:48 < BrainDamage> more like for cheapskates
2011-12-04T23:06:00 < BrainDamage> which makes them awesome
2011-12-04T23:06:16 < Tom_itx> well he mentioned quadrature which was what i was curious about
2011-12-04T23:17:25 < karlp> Tom_itx: chapter 13.2 in RM0041 (for the value line)
2011-12-04T23:17:39 < karlp> so yeah, seems to be in the discovery board too
2011-12-04T23:19:24 < Tom_itx> which is the rm0041 since i named them human readable names?
2011-12-04T23:22:22 < Tom_itx> mmm seems i don't have that one yet
2011-12-04T23:23:03 < Tom_itx> and apparently you can't search with RM0041
2011-12-04T23:24:35 < jpa-> Laurenceb_: ARR is for the period
2011-12-04T23:24:54 < Laurenceb_> i see
2011-12-04T23:25:24 < karlp> stm32f100 programmers reference manual
2011-12-04T23:25:40 < karlp> not to be confused with stm32f10x programmers reference manual (rm0008)

2011-12-05T00:28:25 < Tom_itx> well i probably will be but i'm not messin with it that much yet
2011-12-05T00:28:42 < Tom_itx> collecting pdf's and got the tools working
2011-12-05T00:28:48 < karlp> I've made great progress (in my mind) over the last week,
2011-12-05T00:29:07 < karlp> if I can finish some jobs around the house tonight, I think I've finished with all the demo and undestanding pieces,
2011-12-05T00:29:15 < karlp> about to start something more useful.
2011-12-05T00:29:40 < karlp> I think the biggest problem I had so far was learnign just how _many_ things need to be enabled and turned on before you can use them.
2011-12-05T00:29:59 < karlp> everything's remappable and has so many options
2011-12-05T00:30:33 < karlp> once I finally go tmy head around how the startup stuff worked, each incremental step has so far been pretty easy
2011-12-05T00:30:56 < Tom_itx> the 68332 i played with was somewhat that way
2011-12-05T00:31:49 < karlp> probably the same with most chips, but I can't remember starting a new chip before, the others were all so long ago...
2011-12-05T00:32:09 < karlp> also, avr-libc handles the startup stuff so well it took a long time before i ever had to look at it.

2011-12-05T18:49:17 < joe9> there is a small haskell implementation that I checked out sometime ago. do not remember its' name though.
2011-12-05T18:49:39 < joe9> designed for embedded devices, afairc
2011-12-05T18:50:48 < joe9> ghc and hugs are way too bloated.
2011-12-05T18:58:33 < AK6L> anyone know of a working Forth implementation for the STM32F4?  i'm despairing of ever finishing this port of Riscy Pygness.
2011-12-05T18:59:19 < AK6L> the gdb server and flash utils under linux put my STM32F4 Discovery board in some weird state now, have to flash it under Windows to get it out; doing anything with it under linux seems to throw it right back into crazy mode.
2011-12-05T19:12:59 < karlp> are you still getting that every time you try and flash?
2011-12-05T19:13:16 < karlp> I've got mine in some weird states occasionally, but normally an unplug/replug (or two) fixes it.
2011-12-05T19:14:20 < karlp> can you share the code, and the complete command sequence you're using? and file it all as a ticket on texane's github?
2011-12-05T19:14:55 < karlp> AK6L: mark4 in #avr seems to think that porting forth should only take one night, if you knwo forth, perhaps you could convince him to do it...

2011-12-05T22:19:20 < peabody124> yeah it would be really nice to track down a command we can send to the F4 to reset the STLink without a power cycle
2011-12-05T22:19:31 < peabody124> i still can't reliably flash without a power cycle of both the target and device
2011-12-05T22:19:35 < peabody124> and even then it normally takes twice
2011-12-05T22:19:53 <+Steffanx> buggy tools ftw :p
2011-12-05T22:21:03 < peabody124> heh
2011-12-05T22:21:18 < peabody124> after a while you sort of learn the dance
2011-12-05T22:22:47 < karlp> hmm, mine works pretty reliably on the 32L board,
2011-12-05T22:22:56 < karlp> if I try and press ctrl-c while it's writing flash though..  oooh boy
2011-12-05T22:23:03 < peabody124> haha been there
2011-12-05T22:23:04 < karlp> gdb has to be kill -9'd
2011-12-05T22:23:16 < peabody124> so you do it all through load within gdb?
2011-12-05T22:23:22 < peabody124> i normally just use the flash tool
2011-12-05T22:23:23 < karlp> mixed.
2011-12-05T22:23:32 < karlp> I often just use the flash tool,
2011-12-05T22:23:43 < karlp> but I spent some time getting boot from sram to work,
2011-12-05T22:23:46 <+Steffanx> Found the link karlp ?
2011-12-05T22:23:47 < karlp> and that has to be done through gdb
2011-12-05T22:24:03 < karlp> Steffanx: not yet,
2011-12-05T22:24:09 < karlp> saw the twitter status, just no link in it
2011-12-05T22:24:20 <+Steffanx> Oh, linl
2011-12-05T22:24:22 <+Steffanx> ak
2011-12-05T22:24:46 < karlp> anyone, christmas beer tasting time.
2011-12-05T22:24:46 < peabody124> yeah the odd thing is my bugs are really reproducible
2011-12-05T22:24:59 < peabody124> if i've been running and had a gdb session going, Ctrl-C st-util, run flash
2011-12-05T22:25:06 < karlp> I've got an f4 on order, it's hung up in payment processing at work,
2011-12-05T22:25:07 < peabody124> it will go through the whole sequence normally and fail to verify
2011-12-05T22:25:11 <+Steffanx> Sorry, iceland is too far away
2011-12-05T22:25:13 < karlp> I'll see how it goes again.
2011-12-05T22:25:18 < karlp> ttyl
2011-12-05T22:25:20 < peabody124> reboot both and then the flash goes through
2011-12-05T22:25:48 < karlp> at least though, I have been able to fix anythign by unplugging and replugging at most twice
2011-12-05T22:25:54 < peabody124> yea me too
2011-12-05T22:25:59 < karlp> AK6L seems to get it so locked up he has to boot into windows
2011-12-05T22:26:04 < karlp> which just seems completely whack
2011-12-05T22:26:08 < peabody124> did he say that explicitly?
2011-12-05T22:26:11 <+Steffanx> It seems to be all over the web karlp
2011-12-05T22:26:15 <+Steffanx> Google for "NXP USB VID / PID Program and USB-IF Certification"
2011-12-05T22:26:29 < peabody124> "the gdb server and flash utils under linux put my STM32F4 Discovery board in some weird state now, have to flash it under Windows to get it out; doing anything with it under linux seems to throw it right back into crazy mode."
2011-12-05T22:26:39 < peabody124> it seems like it just never works
2011-12-05T22:26:44 <+Steffanx> karlp "To reduce time to market and overall costs, NXP is taking an important step by offering customers the option to sub-license the company's USB Vendor ID number, eliminating a significant start-up cost for USB product developers"
2011-12-05T22:26:48 < peabody124> not that it's in some unrecoverable state every nth time
2011-12-05T22:43:26 < Laurenceb_> Steffanx: i thought you could already use ST's ids for stm32
2011-12-05T22:43:52 < Laurenceb_> we use Intel vendor/product for Xscale at work :D
2011-12-05T22:44:00 <+Steffanx> Use or .. sub-license?
2011-12-05T22:44:13 < Laurenceb_> hehe
2011-12-05T22:44:31 < Laurenceb_> i think i fried my adc :(
2011-12-05T22:45:01 < Laurenceb_> few days ago i was testing standby mode, i setup the analog rail to shut down and left it overnight
2011-12-05T22:45:22 <+Steffanx> That shouldn't fry it.. or it's buggy
2011-12-05T22:45:32 < Laurenceb_> next day it had discharged a 2Ah battery
2011-12-05T22:45:39 <+Steffanx> Ohom
2011-12-05T22:45:43 < Laurenceb_> even tho it was only drawing a few uA for the RTC
2011-12-05T22:46:08 < Laurenceb_> i didnt realise the analogue supply voltage should always be applied
2011-12-05T22:46:23 < Laurenceb_> it was running with 3v digital supply only
2011-12-05T22:48:05 < Laurenceb_> now my adc output fluctuates around when GPIO is running
2011-12-05T22:48:28 < Laurenceb_> though it was noise at first, but it wasnt happening before
2011-12-05T22:48:46 < Laurenceb_> im guessing the lipo managed to discharge through the adc or something

2011-12-06T01:59:28 < karlp> peabody124: yeah,, I know, but I havne't yet got enough information on specifics to even try to see what's going on.
2011-12-06T01:59:43 < karlp> over the last week I've been mostly just _using_, and so far, so generally good.
2011-12-06T01:59:53 < peabody124> yea i saw that from your commit logs
2011-12-06T02:00:00 < karlp> bugs, yeah, but nothing I can pin down yet, and nothing that was a showstopper
2011-12-06T02:00:16 < karlp> so I'm jus tkeeping on, keeping on.
2011-12-06T02:00:20 < peabody124> but you don't know a command to reset the internal state of the stlink
2011-12-06T02:00:26 < karlp> nope :)
2011-12-06T02:00:38 < karlp> don't worry, I'm not hiding anything from you :) (or anyone)
2011-12-06T02:00:53 < karlp> however,
2011-12-06T02:01:06 < karlp> I was perusing the my.st forums the other night
2011-12-06T02:01:14 < karlp> and it seems this is a general problem, not a linux problem
2011-12-06T02:02:59 < peabody124> hehe well at least it's not a low hanging fruit

2011-12-08T08:50:37 < erik-k> -_- adc seems stupidly overcomplex to set up, or is it just rm0008 overcomplicating things?
2011-12-08T08:51:32 < erik-k> All I want is a single analog sample now and then
2011-12-08T09:36:11 < jpa-> it doesn't have to be overcomplex
2011-12-08T09:36:20 < jpa-> but the more complex modes are often useful, too :)
2011-12-08T11:02:48 < erik-k> I just need to sample the point between a thermistor & resistor about 10 times a second so I can switch a heater on/off
2011-12-08T11:03:49 < erik-k> rm0008 goes into this huge detail about the various modes but (don't have it up at the moment) seemed to leave the "dumb, basic" mode out of the description.

2011-12-08T14:35:27 < jpa-> if you want it easy, just use chibios :)
2011-12-08T14:35:45 <+Steffanx> or not
2011-12-08T15:02:09 < karlp> do you not use an RTOS Steffanx? or just prefer something else?

2011-12-08T15:03:34 < karlp> me either,
2011-12-08T15:03:43 < karlp> I had a look at freertos, and it seems rather complicated
2011-12-08T15:03:51 <+Steffanx> Yeah
2011-12-08T15:04:04 < karlp> used uCosII years back in uni, but haven't really used anything since

2011-12-08T15:06:58 <+Steffanx> I never really needed multitasking
2011-12-08T15:14:53 < Laurenceb> you can generate software interrupts and have them run in a low priority group

2011-12-09T01:25:43 < karlp> man, these 2x25 pin connectors on the F4 discovery board are a bit of a nuisance
2011-12-09T01:26:22 < BrainDamage> yes, I think I'd have preferred a single line, but longer
2011-12-09T01:27:32 < BrainDamage> I love the integrated mic & accelerometer tough
2011-12-09T01:27:52 < karlp> seems interesting
2011-12-09T01:28:02 < karlp> packaging leaves a bit to be desired
2011-12-09T01:28:38 < karlp> the 32L board had a nice description of the modes when you press each button
2011-12-09T01:29:02 < karlp> so did the VL board
2011-12-09T01:29:30 < BrainDamage> the second mode after pressing, is using the accelerometer as tilt sensor
2011-12-09T01:29:38 < karlp> yeah, I figured that out
2011-12-09T01:29:41 < karlp> kinda neat :)
2011-12-09T01:31:01 < BrainDamage> I should get a 32L just to have 'em all >_>
2011-12-09T01:31:32 < karlp> 32L has a nice touch sensor and LCD:)
2011-12-09T01:31:36 < karlp> and it's low power
2011-12-09T01:54:46 < karlp> The demonstration software is preloaded in the board’s Flash memory. It uses the MEMS
2011-12-09T01:54:50 < karlp> motion sensor to blink the four LEDs according to the motion direction and speed.
2011-12-09T01:54:53 < karlp> Connecting the board to a PC with a second USB 'type A to micro-B' cable converts it into a
2011-12-09T01:54:56 < karlp> standard mouse, and board motion controls the PC cursor.
2011-12-09T01:54:59 < karlp> that wouldn't have taken much on the bit of cardboard...
2011-12-09T02:12:20 < Tom_itx> how about a daughter card for the F4 discovery with single row screw terminals?
2011-12-09T02:12:43 < Tom_itx> .1" spacing
2011-12-09T02:13:21 < BrainDamage> 2mm spacing screw terminals? never seen so small
2011-12-09T02:13:40 < Tom_itx> 2.54
2011-12-09T02:15:28 < Tom_itx> http://search.digikey.com/scripts/DkSearch/dksus.dll?vendor=0&keywords=277-1279-ND
2011-12-09T02:18:39 < karlp> even just coming with female headers instead of male...
2011-12-09T02:18:57 < karlp> I kinda want some female/male jumper leads for a few places.
2011-12-09T02:19:33 < BrainDamage> yes, I don't like male connectors either
2011-12-09T02:19:49 < BrainDamage> I bought a pack of female jumper wires
2011-12-09T02:19:50 < Tom_itx> dx has jumper wires
2011-12-09T02:20:01 < BrainDamage> where I plug inside normal wires
2011-12-09T02:20:36 < karlp> 40 pin might have worked, I could have used an old IDE cable..
2011-12-09T02:20:44 < karlp> meh
2011-12-09T02:20:57 < karlp> another night
2011-12-09T02:21:48 < karlp> I think I need another usb micro cable.
2011-12-09T02:22:05 < karlp> I don't have enough new old phones yet
2011-12-09T02:22:17 < karlp> and still have too many of these usb mini ccables

2011-12-09T04:17:30 < jnosky> All the sparkfun brds use female
2011-12-09T04:17:47 < Tom_itx> what about screw terminals
2011-12-09T04:17:50 < Tom_itx> or spring loaded
2011-12-09T04:18:43 < jnosky> My standard procedure is to use dbl row male wire wrap style --------[]----------
2011-12-09T04:19:06 < karlp> pardon?
2011-12-09T04:19:09 < jnosky> On a 1000 hole brd, then I just can plug the dev brds onto whatever im playin with
2011-12-09T04:19:11 < karlp> male wiretap?
2011-12-09T04:19:36 < jnosky> But that wont work here cause they cheaped out and used male
2011-12-09T04:20:30 < jnosky> like this:
2011-12-09T04:20:31 < jnosky> http://www.sparkfun.com/products/676
2011-12-09T04:21:03 < jnosky> You cant even find wire wrap females anymore
2011-12-09T04:21:41 < jnosky> The male - male are not hard to find or scrounge
2011-12-09T04:21:42 < BrainDamage> I tought about desoldering the connectors, but being a double row it's a pita
2011-12-09T04:21:53 < jnosky> Yea I was thinking the same thing
2011-12-09T04:22:09 < jnosky> I still aint firgured out what Im gonna do about ot
2011-12-09T04:22:21 < BrainDamage> I think I'll use some chipquik
2011-12-09T04:22:26 < BrainDamage> even if it's kinda nasty
2011-12-09T04:22:40 < BrainDamage> the low melting point might give me enough time to plug it off
2011-12-09T04:22:53 < BrainDamage> altough it requires troughrough cleaning afterwards
2011-12-09T04:23:07 < karlp> or, you do what you were meant to do, use it for eval, then put it on your own boards? :)
2011-12-09T04:23:29 < jnosky> Yea that route doesnt look so easy, since the legs stick out topside a bit too
2011-12-09T04:23:38 < karlp> jnosky: I mean, when you said, "my sop is to use dbl row male wire wrap style"
2011-12-09T04:23:42 < karlp> what did you mean exactly?
2011-12-09T04:23:59 < BrainDamage> I want to use it for eval, but being able to plug wires 'n stuff would be quite cool for evluation :p
2011-12-09T04:24:07 < karlp> BrainDamage: I do agree, don't worry :)
2011-12-09T04:24:21 < jnosky> its a stik of wire basically with a small seperator comes in strips
2011-12-09T04:24:27 < karlp> the 32L is probably tyhe only one of the three that is breadboard friendly.
2011-12-09T04:24:28 < jnosky> -----------[]------------
2011-12-09T04:24:40 < jnosky> You could wire wrap in the bottom
2011-12-09T04:24:44 < karlp> jnosky: I don't know what your ascii pic is meant to mean,
2011-12-09T04:24:54 < jnosky> plug the board in on top
2011-12-09T04:24:58 < karlp> nor how it helps with the male on both sides headers on all the discovery baords
2011-12-09T04:25:08 < jnosky> it doesnt help
2011-12-09T04:25:14 < jnosky> It what I prefer
2011-12-09T04:25:20 < jnosky> -------is wire
2011-12-09T04:25:26 < BrainDamage> I wonder if a female-female strip exists
2011-12-09T04:25:28 < jnosky> [] is a plastic stopper
2011-12-09T04:25:31 < BrainDamage> that I could just plug on top
2011-12-09T04:25:40 < BrainDamage> would solve all issues
2011-12-09T04:25:45 < karlp> jnosky: that just sounds like the pins that are already there?
2011-12-09T04:26:05 < karlp> BrainDamage: samtec/4u might sell them?
2011-12-09T04:26:09 < jnosky> http://www.king-cart.com/cgi-bin/cart.cgi?store=phoenixent&product_name=HWS2358
2011-12-09T04:26:18 < jnosky> like that only long on both sides
2011-12-09T04:26:48 < karlp> jnosky: so,  you're saying you normally use that on your own boards?
2011-12-09T04:27:11 < Tom_itx> pc100 thru board headers
2011-12-09T04:27:23 < jnosky> Well all the sparkfun brds are females
2011-12-09T04:27:52 < jnosky> I use those pin strips all the time for proto stuff
2011-12-09T04:28:27 < jnosky> Ive got a wire wrap gun, that can cut, strip, and wrap in one operation
2011-12-09T04:29:12 < jnosky> So if that brd had females, I could make a host of project brds
2011-12-09T04:29:33 < jnosky> connectting to those cheap ass dbl headers i showed
2011-12-09T04:29:34 < karlp> but, if you have wirewrap gear, why is this even a problem for you?
2011-12-09T04:29:40 < jnosky> and just plug the whole thing on and off
2011-12-09T04:29:54 < karlp> are they not long enough for your wirewrap gear?
2011-12-09T04:30:13 < jnosky> You mount those dbl row things on a 1000 hole vector brd
2011-12-09T04:30:21 < jnosky> Now you have pins on both sides
2011-12-09T04:30:32 < karlp> I'm sorry, what's 10000 hole vector board?
2011-12-09T04:30:38 < jnosky> you wire up yer peripherals, and plug the whole brd onto it topside
2011-12-09T04:31:00 < jnosky> http://www.google.com/imgres?imgurl=http://tangentsoft.net/elec/bitmaps/vector-board.jpg&imgrefurl=http://tangentsoft.net/elec/breadboard.html&h=381&w=381&sz=55&tbnid=PLXAfl2k7FFMPM:&tbnh=90&tbnw=90&prev=/search%3Fq%3Dvector%2Bboard%26tbm%3Disch%26tbo%3Du&zoom=1&q=vector+board&docid=KxtpEpvCpXB9uM&sa=X&ei=2HLhTpitBuLb0QGptbSIBg&ved=0CEgQ9QEwBA&dur=672
2011-12-09T04:31:03 < jnosky> wow
2011-12-09T04:31:49 < jnosky> did that link work?
2011-12-09T04:31:57 < karlp> I got bits out did.
2011-12-09T04:32:18 < karlp> so,  you stick your big double sided long male/male pins in some vector/perf/vero board
2011-12-09T04:32:22 < karlp> and then what?
2011-12-09T04:32:41 < BrainDamage> I guess he wire wraps or solder each pin

2011-12-09T04:32:54 < BrainDamage> and adds a set of new sockets on the board
2011-12-09T04:32:57 < karlp> I still don't see what you're plugging the male headers on either side of the discovery boards onto your vero board
2011-12-09T04:32:59 < jnosky> Then one side can hold the proto brd, ie you can plug discovery board right onto it
2011-12-09T04:33:13 < jnosky> Then the other side is available for connections
2011-12-09T04:33:27 < jnosky> plus you have tons of extra holes for components
2011-12-09T04:33:30 < karlp> so, you're just wirewrapping straight onto the discovery board headers
2011-12-09T04:33:45 < jnosky> No my plan is ruined
2011-12-09T04:33:49 < jnosky> since stm used male
2011-12-09T04:33:57 < karlp> ok, thank you.
2011-12-09T04:34:01 < jnosky> I dont want to do that
2011-12-09T04:34:06 < jnosky> Than i cant reuse the brd
2011-12-09T04:34:11 < jnosky> for different things
2011-12-09T04:34:12 < karlp> none of what you were saying made any sense with the male headers on the boards :)
2011-12-09T04:34:19 < karlp> no wonder I couldn't understand what you were talking about
2011-12-09T04:34:20 < jnosky> ahh ok sorry
2011-12-09T04:34:56 < jnosky> Thats why we were talking of sewating the males off
2011-12-09T04:34:59 < BrainDamage> just need to find a way to painlessy remove the male headers, or plug a female on top
2011-12-09T04:35:03 < jnosky> sweating
2011-12-09T04:35:09 < jnosky> ya that would be sweet
2011-12-09T04:35:17 < karlp> yeah, I just got confused when you were talking about "that's what you would do"
2011-12-09T04:35:25 < karlp> I thought you meant for the original headers
2011-12-09T04:35:26 < jnosky> or a gender changer
2011-12-09T04:35:29 < Tom_itx> hot air pencil
2011-12-09T04:35:35 < jnosky> Ive not seen one tho
2011-12-09T04:35:44 < BrainDamage> I don't have an hot air tool :/
2011-12-09T04:35:59 < BrainDamage> also, sounds painful even with that
2011-12-09T04:36:02 < karlp> on the bright side, they _were_ nice enough to put boot0 beside vdd and pb2 (boot1) bside gnd
2011-12-09T04:36:04 < BrainDamage> since the strip is long
2011-12-09T04:36:10 < karlp> so they _designed_ in jumpers
2011-12-09T04:36:17 < karlp> but 25x2 is just a damn awkward size
2011-12-09T04:36:24 < BrainDamage> and one side will cool as you warm the other
2011-12-09T04:36:38 < karlp> it's like they spent all the time laying out the cool mems and audio and usb,
2011-12-09T04:36:44 < jnosky> Yea and the thru hole will be plugged when yer done
2011-12-09T04:36:51 < karlp> then went, "oh shit, we forgot we had to putheaders on this"
2011-12-09T04:37:16 < karlp> the VL has that other awkward bane, the rectangular pins,
2011-12-09T04:37:24 < jnosky> males are cheap, that why tehy used em
2011-12-09T04:37:36 < karlp> they coul dhave left them off.
2011-12-09T04:37:44 < jnosky> That would been waay better
2011-12-09T04:37:48 < karlp> plenty of dev boards come without headers
2011-12-09T04:37:57 < karlp> so you can put in what suits your work environment
2011-12-09T04:38:08 < BrainDamage> yeah, that
2011-12-09T04:38:19 < BrainDamage> being able to install myself would've been much better
2011-12-09T04:38:21 < jnosky> I dont reall wanna hard wire to that brd
2011-12-09T04:39:36 < jnosky> normally I have some supporting components for my projects
2011-12-09T04:39:42 < jnosky> They need a place to go
2011-12-09T04:39:47 < jnosky> and a way to interconnect

2011-12-09T12:56:49 < quitte> i can't find documentation for the stdperiphlib. is there any? or am i supposed to go by the examples and headers?
2011-12-09T12:58:39 < jpa-> it sucks, just write to the registers directly (personal opinion :)
2011-12-09T13:00:08 < quitte> i would. but it's for an assignment that demands using the lib for some reason
2011-12-09T13:00:47 < jpa-> too bad
2011-12-09T13:00:55 < quitte> same reason i'm fighting uVision on a linux box
2011-12-09T13:09:01 < karlp> the only docs I've found are the comments in the headers and source
2011-12-09T13:09:13 < karlp> and the example blobs
2011-12-09T13:10:13 < quitte> should've asked that earlier.
2011-12-09T13:10:45 < karlp> it's not terrible when you get used to how it does things.
2011-12-09T13:13:00 < quitte> it's terrible having to learn an ide that i probably won't ever use again by some step-by-step tutorial. and of courese when skipping something the random double click this thing won't work
2011-12-09T13:13:39 < quitte> or maybe it's because the tutorial is outdated. sigh. it'll be over soon.
2011-12-09T14:29:14 < Laurenceb> i quite like the periph lib
2011-12-09T14:34:31 < quitte> any idea about this double click STM32_init.c to get a processor configuration dialogue thingie?
2011-12-09T14:35:44 < quitte> no configuration wizard for me. and i don't quite see how a configuration wizard could be part of a .c file
2011-12-09T14:37:14 < Laurenceb> i dont use any gui
2011-12-09T14:37:25 < Laurenceb> i dont need no stinking gui
2011-12-09T14:38:05 < quitte> it seems nobody does. except for java programmers.
2011-12-09T14:38:46 < karlp> there's an excel sheet that generates the file isn't there?
2011-12-09T14:39:06 < karlp> that startup stuff is what I was recently battling to understand
2011-12-09T14:41:50 < Laurenceb> i just use the startup.s file
2011-12-09T14:43:52 < karlp> I fix0red it.
2011-12-09T14:44:04 < karlp> one of arm's selling points was that you could write startup code i C
2011-12-09T14:44:11 < Laurenceb> lol
2011-12-09T14:44:16 < Laurenceb> mine is asm
2011-12-09T14:44:25 < karlp> yeah, like ST's provided ones.
2011-12-09T14:44:33 < Laurenceb> it probably is...
2011-12-09T14:44:38 < Laurenceb> i grabbed off github
2011-12-09T14:44:58 < karlp> https://github.com/karlp/kkstm32_base/tree/master/startup
2011-12-09T14:45:23 < karlp> just one bit of asm to make it run from sram
2011-12-09T14:45:39 < karlp> which should be possible to get rid of if I work out hte vector tables properly.
2011-12-09T14:45:46 < karlp> but it's enough for now,
2011-12-09T14:46:02 < karlp> plus it gave me a much better understanding of how the linkers and startup stuff all worked together
2011-12-09T14:49:06 < quitte> found the wizard. it's a tab at the bottom of the files editor window.
2011-12-09T14:50:21 < quitte> now to get the simulator working. and i guess then i need to punch something.
2011-12-09T17:15:24 < Laurenceb> hmm im failing to get pwm
2011-12-09T17:15:50 < Laurenceb> i need to enable the timer clk, the alt function io, and set the pins as alt function pp ?
2011-12-09T17:46:01 < quitte> in what way aren't you getting pwm?
2011-12-09T17:46:25 < Laurenceb> nothing on the pins

2011-12-09T17:47:31 < quitte> did you enable the peripheral clock in the apb register?

2011-12-09T18:46:24 < karlp> the std periph lib does lots of argument checking, at least in most places I'd looked at
2011-12-09T18:46:59 < Laurenceb> yeah
2011-12-09T18:47:02 < Laurenceb> weird that
2011-12-09T18:50:27 < karlp> perhaps your environment defines assert to be a noop?

2011-12-10T04:51:53 < TeknoJuce> when people port the arduino bootloaders to stm32's does it run like crap or better then on avrs
2011-12-10T04:52:05 < TeknoJuce> than
2011-12-10T04:53:04 < UnaClocker> I'd imagine you could emulate an AVR faster than an AVR could run, with the ARM.. Since it's native, yeah, it's going to be quite a bit faster.
2011-12-10T04:58:06 < TeknoJuce> was just wondering for something like RepRap where the avr 8bit almost doesnt have enough power to run it but I didnt want to port all the code over to run natively on the stm32 so was hoping if I was able to get someone elses arduino stm32 bootloader working I could then run the reprap firmware ontop of that
2011-12-10T04:58:56 < UnaClocker> TeknoJuce: Yeah, that'd be awesome.
2011-12-10T05:04:29 < UnaClocker> I know there's a MapleLeaf that uses the Arduino boot loader.
2011-12-10T05:08:36 < TeknoJuce> Do you think it would be difficult if their code was avail. to make that work on an STM32F4 Discovery think their board had some extra ram or something on it
2011-12-10T05:09:46 < UnaClocker> Way beyond my skill level, someone could do it, I have no doubt.
2011-12-10T05:09:47 < TeknoJuce> thinkd they use wiring library port or something like that or maybe it was another boar

2011-12-10T05:12:12 < TeknoJuce> what stm32 board do you have?
2011-12-10T05:12:33 < UnaClocker> STM32F4-Discovery
2011-12-10T05:12:49 < TeknoJuce> so wonder if that STM32 F103RB guessing that means its an F1 wonder what the 03RB means
2011-12-10T05:13:40 < TeknoJuce> perfect you and me will port maple to the stm32f4-d and fail awesomely!
2011-12-10T05:14:06 < UnaClocker> hehe.. I haven't even been able to get the blink example to load and run on the board yet.. ;)
2011-12-10T05:15:07 < TeknoJuce> hope you we're able to get the accelerometer mouse app to work :)
2011-12-10T05:15:23 < TeknoJuce> (comes preloaded on the board)
2011-12-10T05:15:45 < UnaClocker> Yeah, I was trying to load a basic example program onto it, figured once I had that down, I'd move on to "adjusting" the example program, and grow from there..
2011-12-10T05:17:05 < TeknoJuce> took me forever to find the windows 7 driver for the v2linker
2011-12-10T05:17:20 < UnaClocker> Yeah, I had a similar adventure on OSX..
2011-12-10T05:17:48 < TeknoJuce> stm32 doesnt seemed to make it easy for the n00bies even thought thats what it seems they are going after with the discovery board
2011-12-10T05:18:09 < UnaClocker> hehe, yeah, must be a different level of newbie.. ;)
2011-12-10T05:19:01 < TeknoJuce> this is for the n00bies born to parents of astrophysicists
2011-12-10T05:20:26 < UnaClocker> hehe.. Have you looked at the source for any of the examples? Just the simple "blink" one that alternates the LED's and implements a delay routine, it looks like a completely different language from the C I'm used to on the Arduino..
2011-12-10T05:35:45 < TeknoJuce> exactly why I wanted to get the arduino bootloader running on it
2011-12-10T05:36:41 < UnaClocker> Yeah.
2011-12-10T06:36:50 < UnaClocker> http://leaflabs.com/docs/bootloader.html   Well I used that git clone thing there, compiled it, and loaded it to my board...
2011-12-10T06:37:07 < UnaClocker> No idea if I compiled it properly for the STM32F4 or not.. Hope so.. ;) heh
2011-12-10T06:37:52 < TeknoJuce> haha so is it working?
2011-12-10T06:39:09 < UnaClocker> I dunno, I seem to be at the same place I got stuck with the blink example.. I loaded the compiled.elf, then type continue, and the green/red (transmit/receive, I assume?) LED's are blinking rapidly..

2011-12-10T12:12:06 < karlp> which "blink_flash" example are you using?
2011-12-10T12:41:46 < erik-k> Effing rm0008 is just flat lying... I can set ADC_CR2_ADON until the cows come home and it never samples
2011-12-10T12:45:53 < karlp> here's my adc init code: https://github.com/karlp/kkstm32_base/blob/master/example/32l_usart_exti_adc/main.c#L136
2011-12-10T12:57:13 < erik-k> What I don't get is, it does exactly /one/ conversion, when I first turn the adc on.
2011-12-10T13:12:17 < jpa-> erik-k: you must set ADC_CR2_ADON back to zero in between if you want to trigger conversions that way
2011-12-10T13:12:23 < erik-k> Aurgh, hell. the interrupt is edge triggered by the EOC bit and I needed to clear it.
2011-12-10T13:12:47 < jpa-> oops no
2011-12-10T13:13:23 < jpa-> exactly the opposite of what i said :)
2011-12-10T13:14:13 < erik-k> But it does say on p228 that reading ADCx->DR wipes EOC back to zero, which evidently doesn't happen (my ISR, as a test, just reads it and prints to serial console)
2011-12-10T13:14:37 < erik-k> -_- well, at least the hair-pulling intervals are getting shorter
2011-12-10T13:18:17 < erik-k> Is there any functional difference between setting ADON vs using SWSTART and setting the regular group to take only 1 sample?
2011-12-10T13:18:55 < jpa-> just use a timer :P
2011-12-10T13:19:43 < erik-k> That's precisely what I'm doing. Every X times the timer ISR is called it bangs the ADC (which is to measure temperature and control a heater)

2011-12-11T20:44:15 < BrainDamage> ok, I'll tell him then
2011-12-11T20:44:32 < karlp> on linux, the udev rules make it popup as /dev/stlinkv1
2011-12-11T20:44:38 < karlp> yeah, sorry, someone came to the door

2011-12-12T13:51:57 < quitte> in the context of interrupts - what is an event?
2011-12-12T14:06:40 < karlp> hehe,I asked the same question the other day :)
2011-12-12T14:07:05 < karlp> I think we decided it was just terminology.  some people use interrupt o be external, and event to be triggered internally.
2011-12-12T14:07:21 < karlp> but given the way the docs refer to them, as best I can tell, they're the same.
2011-12-12T14:18:39 < quitte> from half a sentence somewhere in rm0008 i'm thinking that an event just means writing to the software interrupt event register - to cause an interrupt just as if there had been an edge on the external pin
2011-12-12T14:19:27 < quitte> it must be something more than terminology, as the evil wizard i'm using has a checkbox to enable events and anopther for interrupts on exti
2011-12-12T14:21:01 < quitte> the wizard isn't that evil anymore after i disabled timer interrupts :)

2011-12-12T14:50:43 < Laurenceb> karlp: any progress with exti on b.2?
2011-12-12T15:22:53 < karlp> yeah, syscfg wasn't wired up.
2011-12-12T15:23:15 < karlp> so i twas defaulting to port a,
2011-12-12T15:23:44 < karlp> which for exti2 is pa2, which is the tx line on usart2, so because I had a "I" getting printed out, caused continual interrupts :)
2011-12-12T15:24:02 < karlp> so that's good, but the spi's still not quite right.
2011-12-12T15:24:16 < karlp> I can write bytes to a teensy/avr slave, and it gets them ok,
2011-12-12T15:24:34 < karlp> but writing to the radio doesn't quite work yet.
2011-12-12T15:25:49 < Laurenceb> oh
2011-12-12T15:25:55 < Laurenceb> maybe i messed that up too
2011-12-12T15:26:09 < Laurenceb> so what does your code look like?
2011-12-12T15:26:21 < karlp> hmm, not sure if it's been pushed yet.
2011-12-12T15:26:38 < Laurenceb> 	GPIO_EXTILineConfig(GPIO_PortSourceGPIOA, GPIO_PinSource0);
2011-12-12T15:26:43 < Laurenceb> you missed that?
2011-12-12T15:26:48 < Laurenceb> - or equivalent
2011-12-12T15:27:00 < karlp> yeah, I think so, code's not in front of me right now
2011-12-12T15:27:12 < Laurenceb> ah - i had that code present
2011-12-12T15:27:12 < karlp> and for gpioA, pin0, you don't need it anyway.
2011-12-12T15:27:31 < Laurenceb> i see - it goes to A by default?
2011-12-12T15:27:41 < karlp> yep
2011-12-12T15:28:10 < karlp> which is why it worked just fine when I tested it out with the push button on teh discover board :)
2011-12-12T15:28:29 < karlp> the amount of config with stm32 seems a bit extravagent at times,
2011-12-12T15:28:43 < karlp> but I guess it's the price for being able to route things all over the place.
2011-12-12T15:56:31 < quitte> the exti interrupt causes the TIM2_IRQHandler to execute,too. any hints what to look for?
2011-12-12T16:02:37 < quitte> toggling the gpioc1 pin somehow actually causes the interrupt pending flag of ti2 to be triggered
2011-12-12T16:12:59 < quitte> i put both ISRs at the end of my main.c file. switching the isrs causes the timer interrupt to run the exti isr,too
2011-12-12T16:53:00 < quitte> i just added a function at the very end of the file. it is called on every interrupt.

2011-12-12T17:02:11 < quitte> i don't quite understand how this issue is the same as min, but it helped
2011-12-12T17:05:55 < karlp> I read in some comment somewhere that clearing the status flag as the last statement in the ISR didn't always work
2011-12-12T17:06:07 < karlp> but I too have no idea why it would then go and call some other routine
2011-12-12T17:06:56 < quitte> yes. it needs to be read back to make sure the SR is in the desired state. the other routine thing? I'm entirely puzzled.
2011-12-12T17:08:43 < karlp> except that the stupid ST forum links are all broken
2011-12-12T17:08:50 < karlp> where's that faq item they refer too
2011-12-12T17:09:49 < quitte> i was assuming behind the login. but didn't bother.
2011-12-12T17:11:21 < quitte> dear veandors, i'd prefer to find datasheets on your site. but getting them from random places using google is just so much less hassle.

2011-12-12T17:52:12 < quitte> and the problem is back. wtf!
2011-12-12T17:56:37 < karlp> you sure you're not missing a } somewhere? and your while loop in main is running on or something?
2011-12-12T17:57:51 < quitte> I put main() at the end in all my efforts to pinpoint the problem {}s look good to me
2011-12-12T17:58:38 < karlp> so now it's just calling an apparently unrelated interrupt continually?
2011-12-12T18:00:43 < quitte> after the isr i added void wtf(){}
2011-12-12T18:00:48 < quitte> it gets called
2011-12-12T18:01:31 < quitte> so not even an interrupt calling it. i think i misinterpreted a checkbox earlier, leading me to believe there was an actual interrupt
2011-12-12T18:03:39 < quitte> wtf^2
2011-12-12T18:04:04 < quitte> now i have the exti isr first, then timer, then wtf
2011-12-12T18:04:23 < quitte> when exti gets called wtf gets called. without calling the timer
2011-12-12T18:07:00 < quitte> full rebuild got the behaviour to a slightly more expected one. exti causes timer. timer sometimes causes wtf.
2011-12-12T18:07:23 < quitte> i'll give myself and my computer a break. maybe either of us needs to cool down

2011-12-12T19:36:53 < quitte> the really funny thing is that the problem is triggered even if that struct isn't accessed

2011-12-12T19:38:25 < quitte> yeah. i'll delete that comment. if that is the worst problem i'm happy.
2011-12-12T19:42:05 < jpa-> quitte: well, it is a shortcoming of GCC; partly
2011-12-12T19:42:36 < quitte> keil's cc in this case.
2011-12-12T19:42:37 < jpa-> most hardware registers in STM32 must be accessed on a 32-bit aligned boundary, whereas GCC will happily generate unaligned accesses with struct members
2011-12-12T19:43:05 < jpa-> ok, dunno about that, maybe there is an attribute you could set on the variable
2011-12-12T19:43:24 < quitte> but that struct should be aligned

2011-12-12T19:45:30 < quitte> huh?
2011-12-12T19:45:41 < quitte> if i added named bits?
2011-12-12T19:46:10 < karlp> bit packing in structs is almost always going to cause pain.
2011-12-12T19:46:18 < jpa-> i haven't found a way to use bit-sized structs for hardware registers, atleast not in gcc
2011-12-12T19:48:44 < quitte> sigh. that didn't help.
2011-12-12T19:49:28 < karlp> well, at least you worked out what sort of code not to use :)
2011-12-12T19:49:37 < quitte> so no bitpacking for registers? ever? too bad. i really liked the readability
2011-12-12T19:50:22 < jpa-> quitte: you could check if the keil compiler has an attribute to force aligned access
2011-12-12T19:50:26 <+Steffanx> I don't like it quitte :P
2011-12-12T19:50:38 <+Steffanx> It doesn't make it more readable for me
2011-12-12T19:50:44 < quitte> shifting and masking is way worse imho
2011-12-12T19:50:49 < jpa-> one way to make it more readable is this: https://svn.kapsi.fi/jpa/paatti/gpio.h
2011-12-12T19:50:58 < quitte> instead of just saying: flip that bit
2011-12-12T19:51:41 < jpa-> BSRR and BSR make it easier, though
2011-12-12T19:52:10 < karlp> packing is not defined in K&R

2011-12-12T19:54:02 <+Steffanx> K&R => Trashbin :P
2011-12-12T19:54:19 < karlp> is packing defined in c99?
2011-12-12T19:54:24 < karlp> I don't think that changes anything.
2011-12-12T19:56:20 < quitte> C90 6.5.2 ?
2011-12-12T19:57:26 < karlp> well, it doesn't matter if they don't work anyway :)
2011-12-12T20:00:55 <+Steffanx> btw don't you have to do fancy stuff with volatile?
2011-12-12T20:01:07 < jpa-> yeah, volatile would be important there, too
2011-12-12T20:01:08 <+Steffanx> And perhaps use the packed attribute to try to 'force' it to be apcked?
2011-12-12T20:01:28 < jpa-> but none of that will help if the compiler does not know how the hardware should be accessed
2011-12-12T20:02:13 < jpa-> besides, you would get terrible concurrency issues in that way (main thread reads GPIOC->ODR to change it, interrupt triggers and changes it, main thread undoes the change)
2011-12-12T20:02:20 < jpa-> using BSRR and BRR is the way to go
2011-12-12T20:02:21 < quitte> using that bitfield worked perfectly fine - before i accessed it from an isr
2011-12-12T20:02:23 < karlp> packed takes out the spacing, but it won't change the alignement
2011-12-12T20:02:48 < jpa-> quitte: aha, i guess you were bitten by the concurrency instead of the alignment issue
2011-12-12T20:03:12 < quitte> jpa-: the problem wasn't wrong values
2011-12-12T20:03:31 < jpa-> hm
2011-12-12T20:03:44 < quitte> it was that functions that were written behind the isr were executed additionally to the isr
2011-12-12T20:03:47 < jpa-> well then it is not the issues that i know :P
2011-12-12T20:04:20 < jpa-> both the alignment and the concurrency only cause wrong values & overwriting the register with random data
2011-12-12T20:04:54 < jpa-> you may have an heisenbug hiding somewhere else :)
2011-12-12T20:29:38 < quitte> it was IDR not ODR. but i that should make it even less of a problem
2011-12-12T20:32:13 < quitte> unless - using a bitfield may have caused it to write for some reason - which in turn threw an exception - which there was no handler for?
2011-12-12T20:34:50 < jpa-> hmm i can't remember if barely doing an unaligned read causes an exception
2011-12-12T20:35:12 < jpa-> but it should escalate to hardfault, and you would be crazy to not have a hardfault handler
2011-12-12T20:46:42 < quitte> void HardFault_Handler(void){} doesn't get called
2011-12-12T20:47:12 < quitte> what kind of exception would a write to a read only register be? if such a thing exists?
2011-12-12T20:48:50 < quitte> the starup code comes with quite some handlers. none were called, except reset, of course
2011-12-12T20:54:58 < quitte> http://pastebin.com/MKMXb578
2011-12-12T21:14:20 < jpa-> hmm, nothing wrong with that
2011-12-12T21:15:23 < jpa-> it would be more efficient if the pointer was struct {..} * const gpioc_sr_in = ..
2011-12-12T21:16:31 < quitte> what kind of typecast would i use then?
2011-12-12T21:17:20 < jpa-> (struct foobar * const) IIRC
2011-12-12T21:17:44 < jpa-> the "constant pointer to a non-constant value" syntax in C is a bit tricky looking at first :P
2011-12-12T21:20:51 < quitte> (void *) compiled. didn't change a thing
2011-12-12T21:21:32 < quitte> and to me this whole thing with pointers and their type is still giving me a headache
2011-12-12T21:21:42 < jpa-> yeah well, at most it would only eliminate a single LDR there
2011-12-12T21:23:47 < quitte> sometime this week i'll try real hardware.

2011-12-12T23:30:46 < jpa-> the saving and restoring happens in hardware and takes 6 cycles
2011-12-12T23:30:54 < quitte> i guess it isn't, when i recall the explanations about how a debugger works.
2011-12-12T23:30:55 < jpa-> or was it 12
2011-12-12T23:31:17 < quitte> really? still way better than the pic32 i'm used to
2011-12-12T23:34:49 < jpa-> yeah, and it is quite deterministic
2011-12-12T23:35:08 < jpa-> but IMO DMA avoids many of the situations where you would want low-latency interrupts
2011-12-12T23:35:24 < quitte> what do you mean by deterministic?
2011-12-12T23:35:55 < jpa-> that it always takes the same time (under some conditions etc etc)
2011-12-12T23:36:28 < quitte> ah.
2011-12-12T23:38:06 < quitte> low latency interrupts are nice for dma,too. the first and so far only time i tried dma transfers i was going crazy over trying to switch between transfers
2011-12-12T23:39:38 < jpa-> yeah that is nasty; having two buffers end-to-end and using the "half complete" interrupt to switch is probably the only sane way
2011-12-12T23:43:55 < quitte> i was surprised to find out that on the s3c2442(openmokos cpu) the dma controller has the highest bus priority. so it would block the cpu's memory access. does the stm32 have that problem,too?
2011-12-12T23:45:51 < jpa-> IIRC the stm32 has some kind of round-robin
2011-12-12T23:46:00 < jpa-> so that they both get max. 50%

2011-12-13T22:25:43 < karlp> huh, I just noticed that the stlinkv2 has an extra IN endpoint.
2011-12-13T22:25:55 < karlp> I bet that's the one to use for the SWV/SWO data
2011-12-13T22:26:07 <+Steffanx> probably yes
2011-12-13T22:29:06 < Laurenceb_> oh sweet
2011-12-13T22:29:12 < Laurenceb_> thatd be cool
2011-12-13T22:30:18 <+Steffanx> Good luck reverse engineering it karlp
2011-12-13T22:36:25 <+Steffanx> Download IAR karlp
2011-12-13T22:36:43 <+Steffanx> it has support for SWO for the STLink/v2
2011-12-13T22:37:10 <+Steffanx> Version 6.21

2011-12-13T22:44:20 <+Steffanx> It has STLink + SWO support, not sure if that combination works
2011-12-13T22:44:21 < Laurenceb_> lanchon-stm32-names.inc:EXTERN (DMAChannel3_IRQHandler)
2011-12-13T22:44:25 < Laurenceb_> ^i dont follow
2011-12-13T22:44:31 < Laurenceb_> where is DMA2 isr?
2011-12-13T22:44:50 <+Steffanx> Isn't it combined with another one?
2011-12-13T22:44:59 < karlp> I have atollic on a windows vm, if it hasn't expired.
2011-12-13T22:45:10 <+Steffanx> 30 days..
2011-12-13T22:45:49 < karlp> Laurenceb_: have a look at how I set up the vectors in https://github.com/karlp/kkstm32_base/tree/master/startup,
2011-12-13T22:46:13 <+Steffanx> No dma2
2011-12-13T22:46:20 < karlp> I'm kinda happy with being able to define the cortex m3 vectors in the common startup file, and then the different arch vector tables in separate files.
2011-12-13T22:46:28 < karlp> (though, I haven't actually written the files for the other arches yet)
2011-12-13T22:46:38 < Laurenceb_> i still see no DMA2
2011-12-13T22:46:41 < karlp> (this was part of the work to remove the attollic files from the stlink repo)
2011-12-13T22:46:53 < Laurenceb_> im not getting DMA1Channel1 interrupts from adc1
2011-12-13T22:46:57 < Laurenceb_> for some reason
2011-12-13T22:47:04 <+Steffanx> Define it yourself Laurenceb_ :)
2011-12-13T22:47:21 < Laurenceb_> https://github.com/Laurenceb/STM32-Logger/blob/master/interrupts.c
2011-12-13T22:47:27 < Laurenceb_> it compiles ok
2011-12-13T22:47:32 < Laurenceb_> using lanchon
2011-12-13T22:50:11 < Laurenceb_> ./lib/CMSIS_CM3/stm32f10x.h:  DMA2_Channel1_IRQn          = 56
2011-12-13T22:50:15 < Laurenceb_> that looks ok
2011-12-13T22:50:20 < Laurenceb_> think lanchon is screwed
2011-12-13T22:53:10 < Laurenceb_> how do i disassemble to look at the interrupts section?
2011-12-13T22:53:13 < karlp> lanchon has the ld scripts right, not this: https://github.com/Laurenceb/STM32-Logger/blob/master/lib/CMSIS_CM3/startup/gcc/startup_stm32f10x_md.s
2011-12-13T22:53:27 < karlp> that's where the order and name of the vectors is..
2011-12-13T22:53:43 < Laurenceb_> ah
2011-12-13T22:54:02 < karlp> I'm guessing, seeing as that's the one that has the .o file?
2011-12-13T22:54:10 < Laurenceb_> DMA1_Channel1_IRQHandler
2011-12-13T22:54:14 < Laurenceb_> oh what the hell
2011-12-13T22:54:21 < Laurenceb_> no wonder it doesnt work
2011-12-13T22:54:52 < karlp> yeah, those vector tables are pretty prone to typos I'd say.
2011-12-13T22:55:05 < karlp> I copied and pasted from the pdf to make mine.
2011-12-13T22:55:48 < Laurenceb_> yeah my usb vector table was screwed too

2011-12-13T22:55:56 <+Steffanx> ard
2011-12-13T22:56:08 < Laurenceb_> so do names in lanchon have to match the startup file?

2011-12-13T23:12:07 < karlp> as far as I can see, the linker srcipts just need to make sure that the section gets put in the right place,
2011-12-13T23:12:13 < karlp> it shouldn't have any names in it anywhere.

2011-12-13T23:21:45 <+Steffanx> I tried to make the kext myself and tried to use the file from the stm8 discovery (seems to use the same pid/vid)
2011-12-13T23:21:56 <+Steffanx> but no luck
2011-12-13T23:22:15 < Laurenceb_> lmao

2011-12-13T23:22:41 < karlp> this is just to try and make OSX ignore the mass storage part right Steffanx?
2011-12-13T23:22:42 < Laurenceb_> no clk to the dma - i fail

2011-12-13T23:23:08 < Laurenceb_> stm kit is all at uni so i cant test to be sure :(
2011-12-13T23:23:14 < karlp> I mentioned it to Uwe tonight, but I don't think he's on OSX either.
2011-12-13T23:23:15 <+Steffanx> This is what someone used for os x 10.5 and an stm8 discovery (i have 10.7)
2011-12-13T23:23:16 <+Steffanx> https://github.com/afaerber/stlink/blob/master/darwin/Info.plist
2011-12-13T23:23:19 < karlp> your best bet might be peabody...
2011-12-13T23:23:43 < karlp> yeah, that afaerber code is where we got the idea that we could take away the sg-utils dependency
2011-12-13T23:24:04 <+Steffanx> It seems to be the only way to disable a driver for a device that uses a standard class driver
2011-12-13T23:24:05 < karlp> and though, if you get an F4 or a 32L board,
2011-12-13T23:24:13 < karlp> it works pretty well for programming the 32VL board too :)
2011-12-13T23:24:24 < karlp> and we all just pretend that the v1 doesn't exist :)
2011-12-13T23:24:42 <+Steffanx> I tried to pretend you don't exists, but i failed
2011-12-13T23:24:57 < karlp> I wonder if it's possible to set the VL board into DFU mode and upgrade it's firmware to stlinkv2?
2011-12-13T23:25:17 <+Steffanx> That would be.. nice, but unlikely
2011-12-13T23:25:47 <+Steffanx> Isn't the schematic of the stlink in the datasheet of the discovery board
2011-12-13T23:26:08 < Tom_itx> yes
2011-12-13T23:26:22 < karlp> well, the stlink hardware dongle can be upgraded to v2 can't it?
2011-12-13T23:26:48 < karlp> I would have thought it ws the same basic hardware as the programmer part of the discovery boards?
2011-12-13T23:29:50 <+Steffanx> Yeah, the stlink :P
2011-12-13T23:30:02 <+Steffanx> Some small differences

2011-12-14T13:12:03 < karlp> but I've never used the dma.
2011-12-14T13:12:19 < karlp> are you sure there isn't some nvic stuff you need to turn on the extra interrupts?

2011-12-14T13:28:17 < Laurenceb> wtf
2011-12-14T14:58:12 < quitte> i'm looking at the adc chapter in rm0008 right now. i could need some help about what's going on here. what is an injected channel group?
2011-12-14T14:58:54 < quitte> taking a bunch of samples from another pin while normally sampling from a different pin?
2011-12-14T15:01:26 < quitte> or maybe i need to start wuith a more basic question: for each sample that is taken i have to read that sample from the register in time before the next sample arrives?
2011-12-14T15:04:14 < jpa-> BrainDamage: it looks like the board is for another mcu and they have just added an adapter to make it more "modern"
2011-12-14T15:04:44 < jpa-> i'd rather take the parts separately than as that board :D
2011-12-14T15:05:22 < BrainDamage> hence clusterfuck
2011-12-14T15:06:12 < quitte> hahaha. "add all the things"
2011-12-14T15:19:36 < quitte> i'll ignore the injection thing - it seems that's to solve some problem i need to have first to get it.
2011-12-14T15:20:21 < quitte> is a adc channel always mapped to a unique input pin, or can i have multiple channels on one pin?
2011-12-14T15:28:24 < quitte> ok. afaict a channel always maps to exactly one pin.
2011-12-14T15:53:19 < quitte> where do i find the mappings from the PXn Pins to the ADC Channels?
2011-12-14T16:13:45 < jpa-> they are in the datasheet for the specific device
2011-12-14T16:14:17 < jpa-> (ie. stm32f103 reference manual defines the ADC and stm32f103rb datasheet gives the pins)

2011-12-14T20:18:06 < AK6L> anyone around that wouldn't mind helping an ARM noob with some simple assembly?
2011-12-14T20:18:32 < AK6L> i've been trying for weeks now to get a USART working on this STM32F4 Discovery board, and having very limited success.
2011-12-14T20:21:43 < karlp> is there any particular reason you want to use assembly?
2011-12-14T20:21:59 < karlp> I found the st provided examples with their stdperiph lib worked out just fine.
2011-12-14T20:22:06 < karlp> usart worked almost first go for me.
2011-12-14T20:22:30 < karlp> as with all my experiemtns so far, the hardest thing was getting all the clocks set up, and setting up the pin functions properly
2011-12-14T20:22:40 < AK6L> karlp: i want to use assembly because my ultimate goal is to get this Forth implementation i found, which works on Cortex-M3, working on the STM32F4 Discovery
2011-12-14T20:22:49 < AK6L> and it's written in assembly.
2011-12-14T20:23:46 < AK6L> this is the simple proof-of-concept i'm trying to get working: https://github.com/xunil/riscy-pygness/blob/master/chargen-stm32.asm
2011-12-14T20:24:12 < AK6L> it's just supposed to output ascending low-ascii characters and loop back to the beginning when it hits 'z'
2011-12-14T20:27:03 < karlp> so, what do you get?
2011-12-14T20:32:06 < AK6L> karlp: the same three high-ascii characters over and over
2011-12-14T20:33:41 < AK6L> i have other baffling problems, too
2011-12-14T20:33:53 < AK6L> there's an even simpler program, led-stm32.asm, in that same repo
2011-12-14T20:34:04 < AK6L> when i load that, everything's fine, i can use texane's gdb server and step through it
2011-12-14T20:34:40 < AK6L> but if i load this chargen program, something breaks/freaks out, gdb server doesn't work anymore, and i can no longer use the flash utility (from texane's repo) to write new programs
2011-12-14T20:34:54 < AK6L> have to plug it into a windows box and load the led program back on it
2011-12-14T20:36:20 < AK6L> i'm about ready to toss these discovery boards in the trash.
2011-12-14T20:59:12 < karlp> there was some code committed to the texane repo last night that should help with the disconnect,
2011-12-14T20:59:21 < karlp> it changed the way the debugger detaches from the core.
2011-12-14T20:59:39 < karlp> you could see if that helps, it fixes some problems where the debugger enver worked again for one guy at least,

2011-12-14T21:11:11 <+Steffanx> Apple is weird.. In their docs they say you should NEVER use "IOProbeScore" in a kext. An Apple Engineer says you sometimes have to :)

2011-12-14T21:31:15 <+Steffanx> Especially on how driver matching is done..
2011-12-14T21:31:38 < karlp> you still poking the VL board?
2011-12-14T21:31:41 <+Steffanx> Yeah
2011-12-14T21:32:17 <+Steffanx> I can see my codeless kext, but it still doesn't select MY driver
2011-12-14T21:33:38 < karlp> could be special case for mass storage? to try and be helpful to any and all flash cards?
2011-12-14T21:33:41  * karlp shrugs
2011-12-14T21:34:11 <+Steffanx> probably not.. I think i just don't understand how it works :)
2011-12-14T21:43:20 <+Steffanx> I can cheat.. but that would fuck up all drivers probably :P
2011-12-14T21:43:26 <+Steffanx> or all usb devices
2011-12-14T21:52:04 < karlp> yeah, usb mass storage is a pretty large class of devices .)
2011-12-14T21:52:13 < karlp> you don't want to trample that one too badly :)

2011-12-14T22:38:14 <+Steffanx> I also wonder why the usb logs also mentions "STM32 STlink ….. is a AppleUSBCDC"
2011-12-14T22:40:54 < BrainDamage> my friend said that probably the stlink in the descriptor it shows it as CDC that is controllable trough standard driver
2011-12-14T22:43:13 <+Steffanx> Anyway, I'm @ my "I give up" point again
2011-12-14T23:03:19 <+Steffanx> Oh, I'm still messing with it

2011-12-14T23:04:21 <+Steffanx> Yeah
2011-12-14T23:04:55 <+Steffanx> I tried to mess with a codeless kext
2011-12-14T23:06:34 <+Steffanx> What you tried to do anyway? Afaik the usb mass storage class claims the device, so it's unusable for other applications
2011-12-14T23:06:43 <+Steffanx> Not sure about the though
2011-12-14T23:08:45 <+Steffanx> You have the debug version of the iousbfamily?
2011-12-14T23:08:51 <+Steffanx> I have, you can see it there..
2011-12-14T23:09:50 <+Steffanx> If you install it.. be sure you have the right version, otherwise you'll f*ck up your system
2011-12-14T23:12:00 <+Steffanx> Nah, maybe not.. it's a buggy implementation of the usbms class..
2011-12-14T23:12:34 <+Steffanx> Linux doesn't like it either. It gave lots of I/O errors when i tried it with ubuntu server :)
2011-12-14T23:12:53 <+Steffanx> Do you run lion?
2011-12-14T23:13:24 <+Steffanx> There is this for os x 10.5 ..

2011-12-14T23:13:33 <+Steffanx> Maybe it works for snow leopard too
2011-12-14T23:13:42 <+Steffanx> It doesn't seem to work for me
2011-12-14T23:14:24 < karlp> Steffanx: what errors are you gettting on linux? this with a VL board?
2011-12-14T23:14:49 <+Steffanx> It's really the kernel which doesn't like it karlp
2011-12-14T23:14:54 <+Steffanx> I/O errors..
2011-12-14T23:14:57 < karlp> you _do_ need the modprobe ignore config
2011-12-14T23:15:04 <+Steffanx> Ah
2011-12-14T23:15:15 <+Steffanx> That's probably it
2011-12-14T23:15:29 <+Steffanx> but that doesn't solve the os x issues :P
2011-12-14T23:15:37 < karlp> no, but what you want on OSX is the same thing,
2011-12-14T23:15:44 < karlp> tell the kernel to completely ignore the VID/PID
2011-12-14T23:16:10 < karlp> and don't even attempt to let the mass storage driver try _anything_
2011-12-14T23:17:38 <+Steffanx> http://pastebin.com/QLPYHZxX …. that's what i see
2011-12-14T23:17:57 <+Steffanx> I'm still not sure WHY it selects the IOUSBMassStorageClass
2011-12-14T23:19:10 < karlp> Cpu86: http://pastebin.com/9dp8wtjY
2011-12-14T23:19:15 < karlp> it'll be the same...
2011-12-14T23:19:21 <+Steffanx> It is
2011-12-14T23:19:28 < karlp> the device declares itself as a mass storage device
2011-12-14T23:19:39 < karlp> you just need to tell the kernel to stop trying to load the usb mass storage driver
2011-12-14T23:19:47 < karlp> because it's implementation of said class is busted
2011-12-14T23:19:54 <+Steffanx> You can do that with a codeless kext, but i failed at that :P
2011-12-14T23:20:15 <+Steffanx> maybe some new lion feature?
2011-12-14T23:20:27 < karlp> steve decided you didn't need to do it.
2011-12-14T23:20:38 <+Steffanx> steve?
2011-12-14T23:20:53 <+Steffanx> Can you unload the mass storage class Cpu86 ?

2011-12-15T00:15:13 < AK6L> just because it doesn't say Phoenix or Award when you boot up doesn't mean it isn't essentially a set of Basic Input/Output routines

2011-12-16T12:05:54 < karlp> int on avr is not 8bits.
2011-12-16T12:08:47 < Tom_itx> 16?
2011-12-16T12:08:53 < Tom_itx> and char 8?
2011-12-16T12:10:07 < karlp> on avr, yes, int is 16, char is 8.
2011-12-16T12:10:14 < karlp> and double is only 32.
2011-12-16T12:11:25 < jpa-> you mean long?
2011-12-16T12:11:35 < jpa-> or do they have shorter floating point types too?
2011-12-16T12:13:26 < karlp> double on avr is the same size as float.
2011-12-16T12:13:35 < karlp> both are 32bit
2011-12-16T12:13:55 < jpa-> oh
2011-12-16T12:14:07 < jaeckel> karlp: we're talkin about arm don't we? :D
2011-12-16T12:14:11 < jaeckel> and avr != arm
2011-12-16T12:15:04 < jpa-> well your general rule is not much use if it is not general :)
2011-12-16T12:15:47 < jaeckel> uhm ok, it should've added a 'for arm' at the end of my rule :D

2011-12-16T12:19:36 < karlp> jaeckel: sure, but you made a pretty blanket statement about "native processor word length"
2011-12-16T12:19:55 < karlp> yeah, what jpa said.
2011-12-16T12:20:04 < karlp> I should read the scrollback entirely, not just hte highlighted lines
2011-12-16T12:28:32 < BrainDamage> int is guaranteed to be at least 16 bits, on all platforms

2011-12-16T16:13:43 < BrainDamage> share both?
2011-12-16T16:13:58 <+Steffanx> A directory with an extension, just like .app
2011-12-16T16:13:59 <+Steffanx>  :)
2011-12-16T16:14:12 <+Steffanx> I like that
2011-12-16T16:15:58 <+Steffanx> Argh, i changed something :)
2011-12-16T16:16:28 <+Steffanx> Now it doesn't seem to work anymore
2011-12-16T16:17:13 <+Steffanx> And now it does, weird OS .. OS X
2011-12-16T16:18:35 <+Steffanx> I see they call it 'XXX_shield" or something like that all the time
2011-12-16T16:18:42 <+Steffanx> Where XXX is hte productname
2011-12-16T16:22:20 <+Steffanx> Yeah :P
2011-12-16T16:22:30  * Steffanx goes for a reboot to clear up the mess he made
2011-12-16T16:22:45 <+Steffanx> *clean
2011-12-16T16:22:57 <+Steffanx> I should :p
2011-12-16T16:23:15 <+Steffanx> How do you clean up the kext mess you made?
2011-12-16T16:23:27 <+Steffanx> I want to be 100% sure i have the right/most recent version

2011-12-16T16:36:33 <+Steffanx> OS X loves me.. my keyboard didn't work :S
2011-12-16T16:38:26 <+Steffanx> So I really need my version Cpu86
2011-12-16T16:38:37 <+Steffanx> Your version, without code loads, but doesn't work
2011-12-16T16:38:55 <+Steffanx> My version with the kpi instead of kernel and another version works
2011-12-16T16:40:00 <+Steffanx> So that was the problem with my codeless kext too.. i also used com.apple.kernel all the time
2011-12-16T16:42:18 < BrainDamage> provide both?
2011-12-16T16:42:27 < BrainDamage> one for lion, one for leopard?
2011-12-16T16:42:38 <+Steffanx> C'est possible :)
2011-12-16T16:44:26 < BrainDamage> at least it gives something working for people, until the nature of difference has been ironed out

2011-12-16T16:52:17 <+Steffanx> Safari.. don't talk about that please
2011-12-16T16:52:31 <+Steffanx> Safari is/was big crap in Lion
2011-12-16T16:52:41 <+Steffanx> I guess it was, there's an update, but i didn't install it yet
2011-12-16T16:53:44 <+Steffanx> I was a slow memory eater
2011-12-16T16:53:58 <+Steffanx> And a little unstable
2011-12-16T16:54:30 <+Steffanx> I go for stlink_shield
2011-12-16T16:55:28 < BrainDamage> The Bundle, the Dummy, and the Ugly hack ?
2011-12-16T16:55:35 <+Steffanx> Yeah :P
2011-12-16T16:56:18 <+Steffanx> That's the BundleName BrainDamage
2011-12-16T16:56:39 < Laurenceb> lol
2011-12-16T16:57:32 <+Steffanx> Does that even matter?
2011-12-16T16:57:58 <+Steffanx> Actually it's not a WTF.. it's just designed like that :)
2011-12-16T16:58:27 <+Steffanx> It is?
2011-12-16T16:59:12 <+Steffanx> Oh, no :)
2011-12-16T17:00:01 <+Steffanx> I wonder if that bundle identifier really matters
2011-12-16T17:00:18 <+Steffanx> On the internet they also seem to use things like 'com.libusb.XXX_shield
2011-12-16T17:15:21 < Laurenceb> "just works"
2011-12-16T17:15:40 <+Steffanx> What hwat Laurenceb ?
2011-12-16T17:15:52 < Laurenceb> hehe
2011-12-16T17:16:58 <+Steffanx> what
2011-12-16T17:18:05 <+Steffanx> Yes?
2011-12-16T17:20:53 <+Steffanx> Me too, but i'm pretty sure only kpi works for me
2011-12-16T17:22:30 <+Steffanx> When I use kextstat, i don't even see any kext 'kernel' version
2011-12-16T17:22:58 <+Steffanx> They're all kpi
2011-12-16T17:23:41 <+Steffanx> Yes
2011-12-16T17:23:45 <+Steffanx> And some others
2011-12-16T17:25:22 <+Steffanx> It really seems to be a 32 vs 64 bit issue
2011-12-16T17:26:00 <+Steffanx> As first step maybe try to get it into texane's repo on github :)
2011-12-16T17:26:05 < dekar_> Steffanx, code less next stopped working on lion for me, gives me some architecture error on the syslog
2011-12-16T17:26:16 < dekar_> I switched to HID-API
2011-12-16T17:26:19 <+Steffanx> It works for me now :)
2011-12-16T17:26:33 < dekar_> neat, though HID-API is the way to go imo
2011-12-16T17:26:42 <+Steffanx> I switched from com.apple.kernel to com.apple.kpi
2011-12-16T17:26:46 < dekar_> it just works
2011-12-16T17:26:56 <+Steffanx> This is for the stlink v1 though
2011-12-16T17:27:00 <+Steffanx> No HID stuff
2011-12-16T17:27:01 < dekar_> oh
2011-12-16T17:27:18 < dekar_> umm why do you need to unload anything then?
2011-12-16T17:27:36 <+Steffanx> The usbmsc seems to claim the stlink v1
2011-12-16T17:27:45 < karlp> hid is unrelated to stlinkv1 or v2
2011-12-16T17:27:59 < karlp> v2 is a composite custom device, v1 is a usb mass storage
2011-12-16T17:27:59 <+Steffanx> As it is mass storage/scsi device dekar_ ...
2011-12-16T17:28:38 < dekar_> mass storage -.-
2011-12-16T17:28:44 < BrainDamage> btw, is there any plans to integrate st-util with openObsessiveCompulsiveDisorder ?
2011-12-16T17:28:45 < dekar_> I remember, I think you mentioned that before
2011-12-16T17:28:55 <+Steffanx> You never connected a v1 to windows dekar_ ?
2011-12-16T17:29:02 < dekar_> I don't have any
2011-12-16T17:29:03 <+Steffanx> It really shows up as some usb drive
2011-12-16T17:29:13 < BrainDamage> it did in linux too
2011-12-16T17:29:19 < BrainDamage> until I added a rule not to
2011-12-16T17:29:27 < BrainDamage> gvfs was smart enough to mount it
2011-12-16T17:29:27 <+Steffanx> Can you also see the files?
2011-12-16T17:29:36 < BrainDamage> yeah, 3 html links
2011-12-16T17:29:39 <+Steffanx> Waow :)
2011-12-16T17:29:47 < dekar_> wouldn't FS caching fuck up the communication with the stlink?
2011-12-16T17:29:54 <+Steffanx> When i tried it linux only gave some nice i/o errors
2011-12-16T17:30:05 < BrainDamage> it was unsable as stlink after being mounted
2011-12-16T17:31:11 <+Steffanx> Yeah :P
2011-12-16T17:31:18 <+Steffanx> That's a detail :P
2011-12-16T17:31:45 <+Steffanx> I wonder.. how many people really have issues with the stlink v1 on os x?
2011-12-16T17:32:02 <+Steffanx> but we should really get it into the repo
2011-12-16T17:33:09 <+Steffanx> Make a branch and do a pull request?
2011-12-16T17:33:32 <+Steffanx> I have no idea how it exactly works, karlp knows that

2011-12-16T17:34:26 <+Steffanx> And to show the help files :)
2011-12-16T17:34:39 < dekar__> they could have used it just for the help files

2011-12-16T17:34:52 <+Steffanx> I really have no idea
2011-12-16T17:34:58 < dekar__> they show drivers on usb mass storage

2011-12-16T17:35:27 <+Steffanx> Drivers on the device itself
2011-12-16T17:35:37 < dekar__> really handy
2011-12-16T17:35:47 < dekar__> much better than optical discs

2011-12-16T17:37:08 < dekar__> failed to get an answer so far
2011-12-16T17:37:15 < dekar__> those guys at #fsf are weird
2011-12-16T17:37:28 < dekar__> isn't "viral marketing" a positive term?
2011-12-16T17:38:49 < dekar__> I don't think a public domain wrapper lib would make you GPL-"immune"
2011-12-16T17:40:39 <+Steffanx> Seriously that man should go into politics
2011-12-16T17:40:50 <+Steffanx> Thousand words.. no answer
2011-12-16T17:42:33 < dekar__> haha totally
2011-12-16T17:43:01 <+Steffanx> I also tried a similar question once..
2011-12-16T17:43:10 <+Steffanx> They really can't help you with it
2011-12-16T17:44:38 < dekar__> I guess there is something wrong with my integrity
2011-12-16T17:44:40 < dekar__> XD
2011-12-16T17:47:57 <+Steffanx> So what you/we do Cpu86 ?
2011-12-16T17:50:09 <+Steffanx> me neither :)
2011-12-16T17:52:34 <+Steffanx> Make a load-kext option?
2011-12-16T17:54:23 <+Steffanx> It'seems to be very easy
2011-12-16T17:54:36 <+Steffanx> Fork the stlink repo from texane, do the changes and do a pull request
2011-12-16T17:56:50 <+Steffanx> Not really
2011-12-16T17:57:54 <+Steffanx> I only have the basic knowledge

2011-12-16T19:21:44 < Cpu86> i edited the makefile and the readme
2011-12-16T19:21:51 <+Steffanx> :)
2011-12-16T19:21:57 <+Steffanx> You want my version too?
2011-12-16T19:22:02 < Cpu86> i made a simple shell script ad invoked it by the makefile
2011-12-16T19:22:05 <+Steffanx> my info.plist
2011-12-16T19:22:15 < Cpu86> ok
2011-12-16T19:23:37 <+Steffanx> There's some useless info in that info.plist though
2011-12-16T19:23:44 <+Steffanx> Maybe you/i should remove that
2011-12-16T19:24:03 < Cpu86> if you want i'll modify it

2011-12-16T19:25:21 < Cpu86> here's the readme: http://cl.ly/CfZ2 i added something in the "if you have stlinkv1" section
2011-12-16T19:25:39 <+Steffanx> What do you use to upload things to that website?

2011-12-16T19:27:37 <+Steffanx> Not sure if the version numbers (11.2.0) are a little too specific
2011-12-16T19:28:52 <+Steffanx> Look ok en clear to me Cpu86

2011-12-16T19:30:16 <+Steffanx> It's OS X, not OSX :P

2011-12-16T19:50:35 <+Steffanx> Arh, 'stupid' question time. Is there a way to define extra include/lib paths so gcc knows where it can find some files to include?
2011-12-16T19:50:47 <+Steffanx> I can modify the makefile(s), but that sucks
2011-12-16T20:00:12 < Cpu86> -I for include
2011-12-16T20:00:19 < Cpu86> -L for libs
2011-12-16T20:00:55 <+Steffanx> Yes i know that.. but i have to modify all makefiles for that
2011-12-16T20:01:43 < Cpu86> put them in the overall CFLAGS

2011-12-16T20:02:08 <+Steffanx> Yes, but then i still have to modify all makefiles .. as there is no overall CFLAGS afaik
2011-12-16T20:02:25 <+Steffanx> at least it didn't work last time
2011-12-16T20:03:16 < Cpu86> in every Makefile there's the line CFLAGS+=
2011-12-16T20:03:55 < Cpu86> so if you do: CFLAGS="your options" make
2011-12-16T20:04:10 < Cpu86> it'll "keep" your own cflags
2011-12-16T20:05:03 < Cpu86> did you try the makefile for the stlink?
2011-12-16T20:06:34 <+Steffanx> ops, i didn't mean the CFLAGS, the LDFLAGS :P
2011-12-16T20:07:13 <+Steffanx> And i've other issues now
2011-12-16T20:07:18 <+Steffanx> I like open source :P
2011-12-16T20:10:20 < Cpu86> do you know how to contact texane through his github home?
2011-12-16T20:11:19 <+Steffanx> karlp is the expert
2011-12-16T20:11:27 <+Steffanx> It doesn't compile for me
2011-12-16T20:11:52 < Cpu86> what are you compiling?
2011-12-16T20:12:08 <+Steffanx> Everything :)
2011-12-16T20:12:16 <+Steffanx> but that's not your problem ofcourse :P
2011-12-16T20:12:37 < Cpu86> are you referring to texane?
2011-12-16T20:12:39 <+Steffanx> Someone forgot to test the things he wrote i guess
2011-12-16T20:12:42 <+Steffanx> Yes, your version
2011-12-16T20:12:55 <+Steffanx> Maybe i should try your modifications only
2011-12-16T20:13:14 <+Steffanx> The compile errors have nothing to do with your modifications
2011-12-16T20:13:20 <+Steffanx> At least.. i don't think they have
2011-12-16T20:13:33 <+Steffanx> As long as you didn't touch the code
2011-12-16T20:13:43 < Cpu86> i didn't touch the code
2011-12-16T20:13:54 <+Steffanx> Then it's not your fault
2011-12-16T20:14:00 < Cpu86> only added a folder and an entry in the Makefile
2011-12-16T20:14:08 < Cpu86> strange, it compiles for me
2011-12-16T20:14:26 <+Steffanx> Here it complains about a lot of things
2011-12-16T20:14:43 <+Steffanx> And because "cc1: warnings being treated as errors" .. it doesn't build
2011-12-16T20:15:42 < Cpu86> does the version from github compile?
2011-12-16T20:15:52 <+Steffanx> Haven't check yet
2011-12-16T20:15:57 <+Steffanx> I'll try your modifications first
2011-12-16T20:17:15 <+Steffanx> So it moves the kext to the extension dir so it load at start up?
2011-12-16T20:17:29 <+Steffanx> It seems to work
2011-12-16T20:17:47 < Cpu86> it changes own:group, copy the proper kext, load it and touch the directory
2011-12-16T20:18:03 <+Steffanx> Yeah, but it's not necessary to move it to the ext. directory :)
2011-12-16T20:18:20 <+Steffanx> Unless you really want to load it when you reboot/start/whatever
2011-12-16T20:19:01 <+Steffanx> You probably knew that
2011-12-16T20:19:14 < Cpu86> i think you'll want the kext every time you reboot
2011-12-16T20:19:24 <+Steffanx> Yes
2011-12-16T20:22:23 <+Steffanx> Are you sure you didn't touch the other makefiles?
2011-12-16T20:23:07 < Cpu86> pretty sure
2011-12-16T20:23:49 <+Steffanx> Hmpf weird shit
2011-12-16T20:23:55 <+Steffanx> me is confused :S
2011-12-16T20:29:35 <+Steffanx> I guess my toolchain sucks, I do have to modify all makefiles
2011-12-16T20:29:37 <+Steffanx> How nice
2011-12-16T20:29:52 <+Steffanx> Anyway, it works
2011-12-16T20:33:22 < Cpu86> toolchain?? i have the gcc & co shipped with Xcode
2011-12-16T20:34:32 <+Steffanx> gcc --version gives you?
2011-12-16T20:35:15 <+Steffanx> oh forget about it
2011-12-16T20:35:23 < Cpu86> 4.2.1
2011-12-16T20:35:34 < Cpu86> i still have Xcode 3.2.5
2011-12-16T20:35:57 <+Steffanx> Yeah, I forgot about the fact that they use LLVM
2011-12-16T20:36:51 <+Steffanx> gcc 4.2.x is pretty old :)
2011-12-16T20:38:05 <+Steffanx> I do stupid things today
2011-12-16T20:38:06 <+Steffanx> :P
2011-12-16T20:38:13 <+Steffanx> Probably because i'm a little tired
2011-12-16T20:39:39 <+Steffanx> You can email texane btw Cpu86
2011-12-16T20:39:51 <+Steffanx> texane@gmail.com <= from the authors fie
2011-12-16T20:39:52 <+Steffanx> file
2011-12-16T20:40:16 < dekar> so you're working to get that stlink to work under osx?
2011-12-16T20:40:19 < Cpu86> what a stupid, you're rigth!
2011-12-16T20:40:22 <+Steffanx> It works dekar
2011-12-16T20:40:30 <+Steffanx> v1
2011-12-16T20:40:40 < Cpu86> i'll email to texane later
2011-12-16T20:40:56 < dekar> ah nice :)
2011-12-16T20:40:59 < Cpu86> now i've to go
2011-12-16T20:41:02 < Cpu86> bye
2011-12-16T20:41:04 < dekar> http://www.aliexpress.com/wholesale/wholesale-clone-logic-analyzer.html?SortType=price_asc&SortType=y
2011-12-16T20:41:05 <+Steffanx> After all it was pretty easy
2011-12-16T20:41:08 <+Steffanx> bb Cpu86
2011-12-16T20:41:11 < dekar> those seem to be cool
2011-12-16T20:41:32 <+Steffanx> salea clone
2011-12-16T20:41:35 <+Steffanx> :)
2011-12-16T20:41:37 < dekar> yeah :)
2011-12-16T20:41:45 < dekar> I think I want one
2011-12-16T20:41:46 <+Steffanx> Which is just a usb chip with a backend on the pc
2011-12-16T20:41:51 < dekar> just to try it
2011-12-16T20:41:57 <+Steffanx> See how simple it is
2011-12-16T20:41:58 <+Steffanx> :)
2011-12-16T20:42:11 < dekar> yeah I read an article on that
2011-12-16T20:42:30 < dekar> why isn't there any stm32 based streaming logic analyzer?
2011-12-16T20:42:37 <+Steffanx> Slow?
2011-12-16T20:42:48 < dekar> slow? the stm32?
2011-12-16T20:42:58 < dekar> the newer ones sample at 50mhz afaik
2011-12-16T20:43:12 < dekar> the f1 only has 18mhz though
2011-12-16T20:43:24 <+Steffanx> The usb communication ..
2011-12-16T20:43:27 < dekar> at least I read that somewhere
2011-12-16T20:43:33 < dekar> oh, usb is fast
2011-12-16T20:43:57 <+Steffanx> Yes, but on a stm32 it's slowish :P
2011-12-16T20:44:08 < jpa-> some stm32's have high speed
2011-12-16T20:44:16 < jpa-> but full speed is not going to cut it :)
2011-12-16T20:44:19 <+Steffanx> Yes, but can it really do high speed?
2011-12-16T20:44:24 < dekar> umm those stm32f4 have full 480mbit/s don't they?
2011-12-16T20:44:24 < jpa-> no idea
2011-12-16T20:44:44 <+Steffanx> Yes, but can they really do ~20mbyte/s dekar ?
2011-12-16T20:45:57 <+Steffanx> The logic analyzer you have is better imho dekar
2011-12-16T20:46:12 <+Steffanx> except for the low memory buffer
2011-12-16T20:46:16 < dekar> I know, still those fake ones are funny
2011-12-16T20:46:34 < dekar> also I'd like to have a streaming one in case I need it
2011-12-16T20:46:48 <+Steffanx> Yes, that's a nice thing of that salea thingy
2011-12-16T20:47:35 < dekar> actually usb isn't necessarily needed, you could also write to SD
2011-12-16T20:47:52 <+Steffanx> Isn't SD even slower?
2011-12-16T20:48:02 <+Steffanx> Yes it is, ok :P
2011-12-16T20:48:09 < jpa-> SD is very slow, be happy if you get 4MB/s in SPI mode
2011-12-16T20:48:35 <+Steffanx> Use the dedicated hw of the f4 :)
2011-12-16T20:48:38 < jpa-> some STM32's have the SDIO peripheral, though, i don't know if you could use that without buying the SD card spec
2011-12-16T20:48:39 <+Steffanx> *peripheral
2011-12-16T20:48:52 < dekar> -.-
2011-12-16T20:48:56 <+Steffanx> I think you can.. they even have an example
2011-12-16T20:49:05 <+Steffanx> Or .. maybe it's just an example :P
2011-12-16T20:49:11 < dekar> never knew sd was slow
2011-12-16T20:49:17 < dekar> so? use sram :D
2011-12-16T20:49:19 < dekar> jk
2011-12-16T20:49:24 <+Steffanx> Nah, that's better :)
2011-12-16T20:49:41 < jpa-> use firewire and write directly to RAM on the PC
2011-12-16T20:49:57 <+Steffanx> 1MByte of SRAM is better than that 16k buffer that openbench thing has
2011-12-16T20:50:05 < dekar> so spi is slow? so having an SPI to ethernet IC is a bad idea?
2011-12-16T20:50:24 < dekar> jpa-, haha using DMA :D
2011-12-16T20:50:26 <+Steffanx> doesn't the F4 has 30mbit spi's?
2011-12-16T20:50:42 < jpa-> "slow" is relative
2011-12-16T20:50:53 < dekar> 30mbit sounds slow to me
2011-12-16T20:50:58 <+Steffanx> Relative is also relative
2011-12-16T20:51:08 < jpa-> it is slow relative to 100Mbps ethernet, but fast compared to rs232 :)
2011-12-16T20:51:13 <+Steffanx> The enc28j60 sucks anyway dekar :P
2011-12-16T20:52:51 < dekar> I see :)
2011-12-16T20:54:10 < dekar> I just did the final review of our schematics earlier today and they forgot to ground boot1 even though I told them to do that like thrice :/
2011-12-16T20:54:28 <+Steffanx> Hehe
2011-12-16T20:54:47 <+Steffanx> You a schematic review :)
2011-12-16T20:54:49 < dekar> but it seems like my product will be in production early in 2012 :)
2011-12-16T20:55:09 < dekar> though I basically just wrote the firmware and picked the pins I wanted
2011-12-16T20:55:09 <+Steffanx> your product? :)
2011-12-16T20:55:16 < dekar> flexBox2
2011-12-16T20:55:26 < dekar> wasn't much involved in the hardware
2011-12-16T20:56:11 < dekar> the schematic guy switched over to dc/dc converters :D
2011-12-16T20:56:22 < dekar> he didn't like the linear ones
2011-12-16T20:57:03 < dekar> oh dc/dc doesn't imply switched mode? I mean switched mode then
2011-12-16T20:58:29 < jpa-> switched to switched mode?
2011-12-16T20:59:35 <+Steffanx> Yes yeyes
2011-12-16T21:00:07 < dekar> yeah
2011-12-16T21:00:23 < dekar> which means more power for lasers :D
2011-12-16T21:01:13 <+Steffanx> Which probably means more efficient devices :P
2011-12-16T21:02:17 < dekar> those components he picked are rated up to 3A, somehow no one seems to care about the maximum USB current -.-"
2011-12-16T21:02:29 <+Steffanx> Hehe
2011-12-16T21:05:46 < jpa-> dekar: in switched mode, the switching current is often 2x the actual current, and it is also good to leave some margin :)
2011-12-16T21:07:06 < dekar> oh, didn't know that
2011-12-16T21:07:15 < dekar> but it makes sense I guess
2011-12-16T21:07:37 <+Steffanx> dont guess
2011-12-16T21:08:51 < dekar> wouldn't that result in weird frequencies in the power source?
2011-12-16T21:09:18 < dekar> or is there a capacitor between the source and the actual switching
2011-12-16T21:09:46 < jpa-> there is
2011-12-16T21:09:58 < jpa-> and it does result in awful noise
2011-12-16T21:10:07 < dekar> ah okay, I only knew you need one for the output
2011-12-16T21:10:45 < jpa-> usually both sides, unless your goal is to create a radio transmitter
2011-12-16T21:11:12 < dekar> which would be a pretty cool feature, I could then use stm32 sleep states to generate music :D
2011-12-16T21:20:03 -!- Laurenceb_ [~Laurence@host86-173-192-214.range86-173.btcentralplus.com] has joined ##stm32
2011-12-16T21:20:16 <+Steffanx> To make ADSL signals non-functional?
2011-12-16T21:31:29 < dekar> getting VDSL anyway
2011-12-16T21:31:40 < dekar> actually I don't have internet right now
2011-12-16T21:31:49 < dekar> they cut my ADSL a week ago
2011-12-16T21:32:54 < dekar> and VDSL somehow isn't ready
2011-12-16T21:32:55 < dekar> using some 3g stick I found at the company right now
2011-12-16T21:35:05 < karlp> dekar: FS caching doesn't fuck up comms, because the comms with th stlink are via magic scsi commands given to the device, you don't interact with it via the file system.
2011-12-16T21:36:13 < karlp> also, using HID for everything is a terrible hack.  people are abusing it badly purely because lots of things have a hid driver built in, so they don't need to ship any _extra_ driver software, but they still always need their own app for it.
2011-12-16T21:36:44 < karlp> also, HID support is getting dropped from libusb in windows, so it's going to stop being friendly anyway.  (still debate about that on libusb lists I'm told)
2011-12-16T21:39:29 < karlp> Steffanx: as for not testing, texane's policy is currently, "apply everything that patches cleanly, without any testing at all"
2011-12-16T21:39:35 < karlp> texane master has been broken numerous times.
2011-12-16T21:40:12 <+Steffanx> That sucks
2011-12-16T21:42:50 < karlp> ok, caught up on scrollback.
2011-12-16T21:42:56 < jpa-> it is constantly broken :)
2011-12-16T21:43:03 < karlp> the best way is probably still to fork texane on github, and submit a pull.
2011-12-16T21:43:20 < karlp> I haven't tried Uwe's latest merge yet,
2011-12-16T21:43:27 < karlp> looked like one or two useful bits, and a lot of noise.
2011-12-16T21:43:58 < karlp> Uwe's strange too, uses git, but won't go on github, prefers to email people with 8 or 9 git format-patch files
2011-12-16T21:44:13 < karlp> won't come here, started an extra mailinglist thing.
2011-12-16T21:44:15  * karlp shrugs
2011-12-16T21:45:01 < karlp> if you fork texane on github, I'm more than happy to look things over
2011-12-16T21:45:08 < karlp> make sure it doesn't break on linux at least :)
2011-12-16T21:45:14 <+Steffanx> you are weird too karlp
2011-12-16T21:45:22 < karlp> you're the one using a mac ;)
2011-12-16T21:45:39 <+Steffanx> That doesnt make me weird
2011-12-16T21:45:55 < jpa-> it does :)
2011-12-16T21:46:07 < dekar> karlp, the windows API allows you to access HID devices using the generic windows HID driver
2011-12-16T21:46:08 <+Steffanx> No it doesn
2011-12-16T21:46:09 <+Steffanx> t
2011-12-16T21:46:16 < dekar> thus you can do that without libusb
2011-12-16T21:46:28 < karlp> dekar: sure, but it doesn't meant you should make your devices HID just to use that.
2011-12-16T21:46:34 < dekar> I switched over to HIDAPI which is a wrapper for the windows api
2011-12-16T21:46:38 < karlp> and, that means you have to use the windows api,
2011-12-16T21:46:43 < karlp> rather than one api for all major OSs
2011-12-16T21:46:57 < dekar> karlp, libusb is using the windows api as well
2011-12-16T21:47:02 < karlp> yeah, but not for long...
2011-12-16T21:47:09 < karlp> the hid is being removed
2011-12-16T21:47:20 < dekar> karlp, it still uses the windows api for usb
2011-12-16T21:47:25 < dekar> you have to use native apis
2011-12-16T21:47:29 < dekar> that's how it works
2011-12-16T21:48:15 < dekar> I don't care about libusb being nazi anymore, as I said I use HID-API now which works fine (also an open source project)
2011-12-16T21:48:26 < dekar> karlp, everyone is ranting about me using hid, but it is the most convenient way by far
2011-12-16T21:48:36 <+Steffanx> no way
2011-12-16T21:48:43 < dekar> before HID people have been using FTDI chips so they need no driver
2011-12-16T21:48:52 < dekar> what's better, HID or an FTDI?
2011-12-16T21:48:53 < karlp> only because they were idiots
2011-12-16T21:49:06 < dekar> our last product used an FTDI
2011-12-16T21:49:12 < dekar> the new one uses HID
2011-12-16T21:49:26 < dekar> even projects like the bus pirate use an FTDI
2011-12-16T21:49:32 < karlp> hid's better than ftdi, sure,
2011-12-16T21:49:40 < karlp> but choosing a usb class that matches your device is better
2011-12-16T21:49:50 < karlp> why people did everything with ftdi and serial is beyond me.
2011-12-16T21:49:54 < dekar> I know it is "abusing" it, but my device doesn't need throughput
2011-12-16T21:50:05 < karlp> let's make usb look mor elike serial, because we refuse to learn anything new
2011-12-16T21:50:06 <+Steffanx> Nothing wrong with rs232 karlp
2011-12-16T21:50:07 < dekar> karlp, people did that so it was "driverless"
2011-12-16T21:50:10 <+Steffanx> it's easy to interface
2011-12-16T21:50:13 < karlp> there's lots wrong with rs232
2011-12-16T21:50:20 < dekar> we need an usb device that works with limited windows accounts
2011-12-16T21:50:21 <+Steffanx> tnot reall
2011-12-16T21:50:22 <+Steffanx> y
2011-12-16T21:50:23 < dekar> no admin permissions
2011-12-16T21:51:57 < dekar> karlp, non HID usb was never an option for me, my boss would have wanted me to use an FTDI again
2011-12-16T21:52:16 < karlp> well, as I said, I vastly prefer HID to ftdi :)
2011-12-16T21:52:27 <+Steffanx> i dont
2011-12-16T21:52:39 < dekar> my product only does i2c btw, so throughput isn't an issue
2011-12-16T21:52:40 < karlp> depends what the use case is of course .)
2011-12-16T21:53:27 < dekar> and I agree on rs232 being easier to use, my usb protocol has to handle stuff like fragmentation due to small packet sizes
2011-12-16T21:53:52 < dekar> rs232 is just a stream
2011-12-16T21:54:28 < karlp> with absolutely no definition of what goes where, or when. without both sides agreeing ahead of time.
2011-12-16T21:54:40 <+Steffanx> :)
2011-12-16T21:54:52 < jpa-> rs232, like tcp, is great for stream-style devices; annoying when you need packets
2011-12-16T21:56:01 < dekar> the one time I used rs232 I implemented a small human readable text interface and it worked pretty well
2011-12-16T21:56:48 < karlp> ok, texane's already merged the osx driver
2011-12-16T21:56:53 <+Steffanx> Waow
2011-12-16T21:56:58 < karlp> tar.gz and all.
2011-12-16T21:57:09 < karlp> like I said, he's just in "apply ALLLL THE PATCHES" mode
2011-12-16T21:57:14 <+Steffanx> Hehe
2011-12-16T21:57:34 < dekar> http://www.signal11.us/oss/hidapi/
2011-12-16T21:57:40 < dekar> really easy to use
2011-12-16T21:57:55 < karlp> still, it's all completely irrelevant
2011-12-16T21:58:01 < karlp> neiterht the stlinkv1 or v2 is a hid device :)
2011-12-16T21:58:13 < dekar> still people here are using HID
2011-12-16T21:58:15 < karlp> no would I expect a v3 to be either.
2011-12-16T21:58:35 < dekar> it would suck if it was, the speed is too low for jtag like use cases
2011-12-16T21:58:46 < karlp> but no drivers?!
2011-12-16T21:58:49 < karlp> use HID ALL THE TIME!
2011-12-16T21:58:52 < karlp> remember? :)
2011-12-16T21:59:00 < karlp> sorry, cheap shot...
2011-12-16T21:59:24 < dekar> mass storage does the same :P
2011-12-16T22:00:08 < karlp> and mass storage probably wasn't a terrible idea, if they'd actually implemented mass storage properly
2011-12-16T22:00:20 < karlp> that's been a lot of the problem.
2011-12-16T22:00:44 < dekar> I guess they should have some HID like class with generic OS drivers that doesn't have those HID restrictions
2011-12-16T22:00:49 < jpa-> the "disappear and reappear" behaviour is especially annoying
2011-12-16T22:01:09 < karlp> anyway, home time for me I reckon.
2011-12-16T22:01:14 < karlp> talk to you all later
2011-12-16T22:01:39 < dekar> imo the device should be able to tell the OS whether it wants only administrative users to access it, or everyone
2011-12-16T22:02:38 < jpa-> what kind of device should say "only admins, please"?
2011-12-16T22:02:46 < dekar> I see why a mass storage device shouldn't be writeable by everyone
2011-12-16T22:02:55 < dekar> it would break the whole FS permissions
2011-12-16T22:03:13 < dekar> every user could just make all files SUID on unix systems
2011-12-16T22:03:21 < dekar> that would be a root exploit
2011-12-16T22:04:04 < jpa-> that is still a problem that can be only solved on the OS level
2011-12-16T22:04:59 < jpa-> and it is quite easy to solve under linux
2011-12-16T22:05:32 < dekar> also unprivileged users would steal root's data
2011-12-16T22:05:39 < jpa-> if udev wasn't so obscure, it should even be easy to configure "these ports at the back of the PC are admin-only; these ports in the hub sitting on the table are for the currently logged-in user"
2011-12-16T22:06:42 < jpa-> but windows is the actual problem.. currently it makes no sense which devices need admin access and which don't
2011-12-16T22:06:59 < dekar> yeah
2011-12-16T22:07:07 < dekar> windows should ship with the libusb driver
2011-12-16T22:07:12 < dekar> would solve all problems :D
2011-12-16T22:08:51 <+Steffanx> libusb1.0 please
2011-12-16T22:09:11 < dekar> and load it for all PID/VIDs :)
2011-12-16T22:09:19 <+Steffanx> Yeah sure
2011-12-16T22:09:25 < dekar> haha

2011-12-16T22:54:36 < karlp> more and more at least.
2011-12-16T22:54:57 < karlp> I've found the bad commit, or at least the first one.

2011-12-17T00:15:59 < karlp> so, quick poll, if you use stlink's "flash" tool, to just write a binary to flash, would you expect the tool to reset and start the device running again?
2011-12-17T00:16:12 < karlp> or simply exit debug mode, requiring some form of reset by the user manually?
2011-12-17T00:16:24 < karlp> or, I guess a third, optionally reset and run.
2011-12-17T00:16:39 < karlp> (one of the recent patches merged changed it from reset and run, to simply detach)
2011-12-17T00:25:38 <+Steffanx> karlp, i'd like reset and run
2011-12-17T00:25:52 <+Steffanx> I like that because it's how it works with AVR's most of the time :)
2011-12-17T00:27:32 < karlp> I would tend to agree
2011-12-17T00:27:55 < karlp> I was thinking even more was broken in these new merges from Uwe until I remembered what he'd done.
2011-12-17T00:28:23 < karlp> Steffanx: how hard is it for a user to rebuild the kext stuff themselves?
2011-12-17T00:28:31 <+Steffanx> No
2011-12-17T00:28:56 <+Steffanx> Actually the project is quite useless imho
2011-12-17T00:29:33 <+Steffanx> A codeless kext is not more than a 'directory' with a extension, which contains a directory 'Contents' which contains a file called 'Info.plist'
2011-12-17T00:29:34 <+Steffanx> That's all
2011-12-17T00:29:46 < karlp> so you only really need: stlink_shield10_6.kext/Contents/Info.plist
2011-12-17T00:29:51 < karlp> and the one for 7
2011-12-17T00:29:56 < karlp> none of the rest of the cruft?
2011-12-17T00:30:14 < karlp> what about the Resrouces and the InfoPlist.strings?
2011-12-17T00:31:14 < karlp> is that just used to replace the default string/key pair if people wanted more languages?
2011-12-17T00:31:24 <+Steffanx> That's not necessary afaik
2011-12-17T00:32:17 <+Steffanx> I have to test it though
2011-12-17T00:32:36 < karlp> ok, if you can try that, I'll tidy up how this is packaged, try and update the docs a bit for that too.
2011-12-17T00:33:16 <+Steffanx> Just keep it for now :)
2011-12-17T00:35:20 < karlp> ok.. :)
2011-12-17T00:35:31 <+Steffanx> I'll try tomorrow
2011-12-17T00:38:06 < karlp> what was this about having to retouch that directory every boot?
2011-12-17T00:38:20 < karlp> that "install.sh" that copies the plist, is that then permanent?
2011-12-17T00:38:56 <+Steffanx> Very permanent
2011-12-17T00:39:34 <+Steffanx> It copies the kext to the extension directory
2011-12-17T00:39:40 <+Steffanx> And touches that dir, so os x knows something changed
2011-12-17T00:39:53 < karlp> good good.
2011-12-17T00:40:10 < karlp> how can people check that they have this running?
2011-12-17T00:40:52 <+Steffanx> Uhm..
2011-12-17T00:41:51 <+Steffanx> I'm not sure how.. the only way i know of is using the usb prober and see if the usb mass storage driver doesn't gets loaded
2011-12-17T00:41:56 < karlp> ok, no worries then :)
2011-12-17T00:42:12 < karlp> this 10.6 vs 10.7 thing,
2011-12-17T00:42:27 < karlp> I take it 10.7 is the way forward?
2011-12-17T00:42:36 < karlp> so it should only use 10.6 for 10.6, not for anything that's not 10.7?
2011-12-17T00:42:49 < karlp> are you on 10.6 or 10.7?
2011-12-17T00:42:55 <+Steffanx> Lion :)
2011-12-17T00:42:58 <+Steffanx> Which is 10.7
2011-12-17T00:43:02 < karlp> oh, fuck it, it can stay as it is.
2011-12-17T00:43:10 <+Steffanx> Cpu86 uses 10.6
2011-12-17T00:43:10 < karlp> when another one comes out, someone can patch the installer then.
2011-12-17T00:58:39 < karlp> Steffanx: https://github.com/karlp/stlink/tree/merge-temp should have a better readme at the top level, and less clutter for the osx.
2011-12-17T00:59:14 < karlp> I've got to fix the 32L flash writing though before I'm goign to ask texane to pull.
2011-12-17T00:59:30 <+Steffanx> :)
2011-12-17T00:59:31 < karlp> 32L flashing is totally busted right now in master, as is gdb.
2011-12-17T00:59:38 <+Steffanx> :S
2011-12-17T01:00:00 < karlp> I've fixed gdb in that merge-temp branch though.
2011-12-17T01:02:52 <+Steffanx> I like how messy some projects are :P
2011-12-17T01:03:26 < karlp> I do not.
2011-12-17T01:03:35 < karlp> I thought this project was getting _better_
2011-12-17T01:03:39 < karlp> not going backwards.
2011-12-17T01:04:02 < karlp> I'm trying to keep my master always working at least.

2011-12-18T00:48:59 < CheBuzz> So is stlink working with openocd now?
2011-12-18T00:49:42 < karlp> god no.
2011-12-18T00:49:58 < karlp> when openocd gets their swd stuff sorted out I'll try and work on getting it merged in.
2011-12-18T00:50:02 < CheBuzz> Haha, ah, ok.  I though I had seen talk about integrating it a while back
2011-12-18T00:50:12 < karlp> oh, it's on the list of things to do :)
2011-12-18T00:50:17 < CheBuzz> Is it possible to use gdb with it then?
2011-12-18T00:50:23 < karlp> but then I started digging in the openocd source
2011-12-18T00:50:31 < karlp> and realised they weren't quite ready for swd stuff yet.
2011-12-18T00:50:37 < karlp> it is possible to use with gdb,
2011-12-18T00:50:49 < karlp> with the caveat that a recent merge broke the texane master.

2011-12-18T00:51:13 < karlp> master here: https://github.com/karlp/stlink is being kept stable
2011-12-18T00:51:59 < CheBuzz> Do does it just act as a remote gdbserver?  (I've only ever used it to flash)
2011-12-18T00:52:07 < karlp> yes, it's aremote gdb server
2011-12-18T00:52:21 < karlp> the pdf in the doc/tutorial example shows some very basic methods on how to use it
2011-12-18T00:52:46 < karlp> it's basically (in one window): ./gdbserver/st-util
2011-12-18T00:52:58 < karlp> and in another, arm-none-eabi-gdb blah.elf
2011-12-18T00:53:05 < karlp> target ext :4242
2011-12-18T00:53:08 < karlp> load blah.elf
2011-12-18T00:53:16 < karlp> continue to start running
2011-12-18T00:53:35 < CheBuzz> Ah ok.  I'm going to try to get it working under Eclipse
2011-12-18T00:54:12 < CheBuzz> Basically the same idea as JTAG->OpenOCD
2011-12-18T00:55:52 < karlp> should behave the same
2011-12-18T00:56:00 < karlp> just with a different command syntax to get the server started
2011-12-18T00:56:09 < karlp> we're not trying to reinvent any wheels
2011-12-18T00:56:13 < karlp> not any big ones anyway :)
2011-12-18T00:56:24 < CheBuzz> Right.  I have cloned your git repo and have built it, so I'll let you know how it goes
2011-12-18T00:57:04 < karlp> more usage reports are always better :)
2011-12-18T00:57:10 < karlp> what target device?
2011-12-18T00:57:18 < karlp> which stlink?
2011-12-18T00:57:52 < CheBuzz> Target device is the STM32F4-Discovery board.  stlink is from your repo.
2011-12-18T00:57:57 < CheBuzz> ls
2011-12-18T00:58:13 < karlp> that's a pretty well used combo, should be fine.
2011-12-18T00:59:00 < CheBuzz> Yes, nothing drives free development like free hardware :)
2011-12-18T01:01:58  * karlp mutters about region based bullshit promos
2011-12-18T01:04:38 < CheBuzz> Wish I had some more, I'd send you one.  Unfortunately I've only got the one left for myself.  The ones that my wife, mother-in-law, 3 year-old, and 1 year-old all "ordered" were donated to a few non-US/Canada friends
2011-12-18T01:05:13 < CheBuzz> Works just as expected by the way karlp.  Thank you!
2011-12-18T01:05:43 < karlp> I have one, but I paid for it :)
2011-12-18T01:06:12 < karlp> there was a massive explosion in use/abuse/misuse of stlink when that promo came out :)
2011-12-18T01:06:24 < karlp> I wonder how many of them are in circulation vs the VL and L boards?
2011-12-18T01:06:55 < karlp> stlink was only _just_ getting the 32L board (well, the stlinkv2 in general) working, when there was this massive shitstorm of activity all of a sudden.
2011-12-18T01:06:58 < karlp> fun times :)
2011-12-18T01:08:34 < karlp> man, semiconductor pricing is awesome. stm32f217, 1 meg flash, 15.27
2011-12-18T01:08:41 < karlp> with 512k flash, 15.31
2011-12-18T01:09:22 < CheBuzz> Higher cost for less flash?  That's odd.
2011-12-18T01:09:37 -!- district is now known as pineapples
2011-12-18T01:09:59 < karlp> not uncommon in my reading.
2011-12-18T01:10:08 < karlp> they might have originally been priced differnently,
2011-12-18T01:10:20 < karlp> but through demand for varioius models, the final retail channel pricing gets a bit mixed up :)
2011-12-18T01:10:51 -!- pineapples is now known as district
2011-12-18T01:11:04 < CheBuzz> Seems flashing is not working in that version though karlp
2011-12-18T01:12:12 < karlp> through gdb it very very very much depends on how you set up the sections and linker scripts.
2011-12-18T01:12:29 < karlp> via the cli flash tool, you just need a bin and an address
2011-12-18T01:12:44 < CheBuzz> Yes, that is what I was referring to, the cli tool
2011-12-18T01:12:55 < karlp> really?
2011-12-18T01:13:20 < karlp> does it flash, but your app doesn't work?
2011-12-18T01:13:20 < CheBuzz> I get:

2011-12-18T01:13:24 < karlp> or does it report errors flashing?
2011-12-18T01:13:29 < CheBuzz> And there it hangs forever
2011-12-18T01:13:49 < CheBuzz> It works just fine using MikeSmith's branch

2011-12-18T01:14:18 < CheBuzz> Same thing
2011-12-18T01:14:32 < karlp> interesting.
2011-12-18T01:14:41 < karlp> well.... use his then :)
2011-12-18T01:15:01 < karlp> I know mine is still working for 32L and 32VL, the f4 is still in a box at the moment, been busy.
2011-12-18T01:15:11 < karlp> I hate it when this shit falls apart again.
2011-12-18T01:15:24 < karlp> I wonder where I broke mine for the f4 boards?
2011-12-18T01:15:28 < CheBuzz> No problems then.
2011-12-18T01:15:37 < CheBuzz> I only tested yours because his is very slow.
2011-12-18T01:15:49 < karlp> mine should be the same speed.
2011-12-18T01:15:55 < karlp> no-ones done any work to speed tha tup yet.
2011-12-18T01:16:07 < karlp> I've been struggling to keep it actually working on all major targets
2011-12-18T01:16:14 < karlp> seems to be a game of whackamole
2011-12-18T01:16:21 < CheBuzz> Ah, so even on 32L and 32VL it is as slow?  As in, 4kb chunk takes about 3-5 seconds
2011-12-18T01:16:40 < karlp> oh, no, I mean, an F4 will be the same on all forks at the moment
2011-12-18T01:16:45 < karlp> I haven't seen any commits to fix that.
2011-12-18T01:17:05 < karlp> 32L is fairly slow, 32VL has an sram loader that's decent, but not awesome.
2011-12-18T01:17:06 < CheBuzz> That's fine then.
2011-12-18T01:17:30 < karlp> both the 32L and f4 have other flash programming modes that haven't been implemented yet
2011-12-18T01:17:39 < karlp> so they _will_ get faster,

2011-12-18T01:23:41 < CheBuzz> With stlink, do you need to do anything special to mask interrupts while you step through the code?  Like "monitor cortex_m3 maskisr on" ?
2011-12-18T01:26:19 < karlp> I believe that falls into the, "reasons to move the back end into openocd, instead of having our own gdbserver implementation"
2011-12-18T01:26:38 < karlp> there is some support for monitor commands, but it's all very basic.
2011-12-18T01:26:54 < karlp> and I don't remember seeing anything to turn off interrupts while stepping or anything.
2011-12-18T01:27:23 < karlp> I personally don't have a lot of experience using gdb(server) in embedded anyway.
2011-12-18T01:27:38 < karlp> I might try and smack the code around a lot, but I'm hardly an expert in this area.
2011-12-18T01:29:53 < CheBuzz> No worries, it appears to be working fine.

2011-12-18T12:59:43 < philpem> Is it possible to use GDB to debug a Flash-based application? I'm having no end of trouble with it
2011-12-18T12:59:56 < philpem> This is on an STM32VL-Discovery, BTW.
2011-12-18T13:52:56 < jpa-> it is possible and it works fine for me
2011-12-18T13:53:37 < jpa-> using that very same board and karlp's (some a bit old) version of stlink
2011-12-18T13:54:16 < jpa-> texane's stlink has been broken quite often lately
2011-12-18T13:56:04 < jpa-> try this https://github.com/karlp/stlink/tree/  or https://github.com/PetteriAimonen/stlink

2011-12-18T14:39:55 < philpem> jpa-, well, I've tried Mike Smith's branch... will try the other two
2011-12-18T14:40:56 < philpem> my problem with the 'mikesmith' fork is that it appears to flash code in, but GDB won't execute it properly
2011-12-18T14:41:27 < philpem> if I put a breakpoint on 'main', it never breaks
2011-12-18T14:57:29 < philpem> 'file test' 'load test' 'break main' 'continue' gets the chip stuck in a loop at "0x08001efc in WWDG_IRQHandler ()"

2011-12-18T16:11:26 < philpem> it was running the ST Micro demo firmware (the LED blinker thing)... don't know if the flash needs erasing (or how to do it if it does)
2011-12-18T16:12:08 < philpem> (also, i'm idling -- if it's >10 mins since I posted, prefix your message with my /nick -- it makes xchat blink the tray icon)

2011-12-18T16:32:12 < karlp_> this was an unexpected changd pushed in from Uwe
2011-12-18T16:32:25 < karlp_> you have to press reset yourself..
2011-12-18T16:32:41 < philpem> this is the karlp branch...

2011-12-18T17:23:49 < philpem> ... the hell?
2011-12-18T17:24:09 < philpem> wrong damn linker script.
2011-12-18T17:25:23 < philpem> no suitable linker scripts in the ST libraries either?
2011-12-18T17:30:44  * philpem makes a note: write a shell or python script to build STM32 linkscripts and throw it on github
2011-12-18T17:38:33 < jpa-> that might work: https://svn.kapsi.fi/jpa/paatti/stm32.ld
2011-12-18T17:39:01 < jpa-> though the linker script is often fairly tightly bound into your startup code and especially into the C runtime initialization
2011-12-18T17:39:59 < jpa-> the codesourcery toolchain also comes with generic-m.ld, which often works
2011-12-18T17:41:29 < philpem> the problem is, ST seem to rely on toolchains which auto-generate linker scripts
2011-12-18T17:42:03 < philpem> so they provide one or two as part of the examples, but i suspect the rest are either built on the fly when needed, or included with the toolkits
2011-12-18T17:42:13 < philpem> (IAR, Keil, Atollic...)
2011-12-18T17:42:48 < jpa-> well, every toolchain has its own linker script format
2011-12-18T17:43:03 < philpem> good point
2011-12-18T17:43:15 < philpem> truestudio seems to use LD
2011-12-18T17:43:21 < jpa-> from what i have seen, most linker scripts (such as the one that comes with codesourcery) are horribly complicated
2011-12-18T17:43:48 < philpem> mmm
2011-12-18T17:43:50 < jpa-> truestudio uses GCC
2011-12-18T17:44:06 < jpa-> IAR and Keil have their own compilers IIRC
2011-12-18T17:44:44 < jpa-> i like the very basic linker scripts, such as the one pasted above; but of course it might not work perfectly for C++ static initializers etc.
2011-12-18T18:02:47 < philpem> yay, it works! :)
2011-12-18T18:02:55 < philpem> had to fix the LD-script

2011-12-18T19:20:35 < philpem> not sure what ".ARM.attributes" is supposed to do, or the ">ram AT>rom" tacked onto the .data segment
2011-12-18T19:22:42 < jpa-> >ram AT >rom means that the initialization values are stored in rom, while the actual data is accessed from ram
2011-12-18T19:23:02 < jpa-> it is the responsibility of the C runtime to copy them
2011-12-18T19:24:12 < philpem> ah.
2011-12-18T19:25:29 < philpem> so effectively it tells the linker "store this stuff in flash, but link the rest of the code to access it from RAM"
2011-12-18T19:26:58 < jpa-> yeah
2011-12-18T19:38:17 < philpem> guess the next step is to make an LED blink.. then make one of the DOGM displays do "something useful" :)

2011-12-19T14:05:38 < karlp_> so... someone's allegedly added stlink support to openocd.
2011-12-19T14:05:47 < karlp_> I have no idea how it works from the code submitted,
2011-12-19T14:06:10 < karlp_> but if anyone uses openocd, and wants to try it out, this is the changeset: http://openocd.zylin.com/#change,279
2011-12-19T14:06:15 < karlp_> (I haven't tried this out at all)
2011-12-19T14:07:16 < karlp_> oh, ok, it needs multiple other proposed commits
2011-12-19T14:13:33 < BrainDamage> great news, let's hope he reused code from the current work and he didn't invent yet another wheel
2011-12-19T14:16:21 < karlp_> he did, it's all based on texane/stlink stuff, from some point in time.
2011-12-19T14:16:29 < karlp_> though of course, now it's all gpl, rather than bsd.
2011-12-19T14:16:40 < karlp_> whatever.
2011-12-19T14:16:55 < karlp_> it would have been nice if he'd spoken to _anyone_ about this,
2011-12-19T14:16:57 < karlp_> but so be it.
2011-12-19T14:17:04 < karlp_> this is a good thing
2011-12-19T14:17:16 < karlp_> should have more testing, should hopefully be more stable from here
2011-12-19T14:17:55 < BrainDamage> should also be more widespread, openocd is much more known tool than stlink's software
2011-12-19T14:18:22 < karlp_> oh absolutely.
2011-12-19T14:18:32 < karlp_> though openocd needs to drastically overhaul their docs and website.
2011-12-19T14:18:42 < karlp_> no useful working releases for a lot of targets
2011-12-19T14:18:52 < karlp_> still, maybe I can do that now.
2011-12-19T14:19:02 < karlp_> also, it looks like it only supports the stlink v2,
2011-12-19T14:20:03 < BrainDamage> probably because it doesn't abuses usb protocol badly so it doesn't need fancy udev rules or the kernel extension on mac
2011-12-19T14:21:43 < BrainDamage> it still would be nice if it would, since many boards / devices are out there to support, and those anti-hack are like 1 file large
2011-12-19T14:22:36 < karlp_> looks like the guy who did is the first person seen using an F2.
2011-12-19T14:22:46 < karlp_> which I'm pretty sure probably had pretty poor support in stlink,
2011-12-19T14:23:16 < karlp_> so he probabyl took some half code from stlink, did all the rest, and put it in openocd rather than in stlink.
2011-12-19T14:23:21 < karlp_> still, good for him,
2011-12-19T14:23:32 < karlp_> I couldn't work out how to make stlink code fit into openocd's architecture
2011-12-19T14:23:42 < karlp_> he's clearly someone who'd been hacking on openocd before

2011-12-19T14:50:26 < BrainDamage> I think some complexity is inherently necessary, due to having to support all sorta tools, and probably there's tens of people working on it at the same time, which tends to tangle code up by itself

2011-12-20T21:29:24 < BrainDamage> I forgot who mentioned it, but st published a dev board for the stm32w chip, it's not a discovery tough, and costs 46$ on digikey: http://www.st.com/internet/evalboard/product/251361.jsp
2011-12-20T21:30:17 <+Steffanx> 46$ :(

2011-12-20T21:31:12 < BrainDamage> I agree they exceeded a bit on the price
2011-12-20T21:31:19 < BrainDamage> esp compared to the discovery boards
2011-12-20T21:32:57 <+Steffanx> Yeah

2011-12-23T23:43:41 < sourcebox> Hi. Can anybody help me regarding gdbserver with STM32L-DISCOVERY?
2011-12-23T23:45:45 -!- Thorn [~Thorn@unaffiliated/thorn] has joined ##stm32
2011-12-23T23:51:46 < jpa-> sourcebox: yeah, just ask
2011-12-23T23:52:16 < jpa-> (though i have used only STM32VL-discovery myself)
2011-12-23T23:53:04 < sourcebox> I have a new board which is still running the demo. gdbserver seems fine, but I ran into "Load failed"error in gdb
2011-12-23T23:54:14 < sourcebox> gdb seems to "see" my code because I can use "run" and "continue"
2011-12-23T23:54:45 < jpa-> which gdbserver branch are you using?
2011-12-23T23:54:55 < sourcebox> I gives me correct hints where the execution has been stopped but the board itself is not flashed
2011-12-23T23:55:18 < sourcebox> I've compiled it from here https://github.com/texane/stlink
2011-12-23T23:55:23 < jpa-> IIRC the gdbserver source code includes flash register addresses separately for each controller - perhaps it doesn't know about the stm32l one
2011-12-23T23:56:29 < jpa-> hmm, looks like it should know it
2011-12-23T23:56:38 < sourcebox> But the examples that come with stlink have this board
2011-12-23T23:57:10 < sourcebox> gdbserver seems to work because I can start und stop the board
2011-12-23T23:57:19 < jpa-> the texane tree has been broken sometimes (reckless applying of patches without testing)
2011-12-23T23:57:22 < sourcebox> from within gdb
2011-12-23T23:57:23 < jpa-> you can try this https://github.com/karlp/stlink/tree/
--- Day changed Sat Dec 24 2011
2011-12-24T00:00:41 < sourcebox> The strange thing is that I can start/stop execution on the board so communication should work
2011-12-24T00:01:48 < sourcebox> My impression is that something on gdb itself is not configured correctly so it doesn't know what to do with the elf file

2011-12-24T00:11:40 < sourcebox> Ok, I'm trying to do some thing manually. First converting .elf to .bin
2011-12-24T00:15:33 < jpa-> elf should work for flashing
2011-12-24T00:15:57 < jpa-> but the logic for actually writing flash is in stlink gdbserver
2011-12-24T00:16:31 < jpa-> you could try to get debug out of gdbserver
2011-12-24T00:16:35 < sourcebox> Yes, but I try to use the flash command from the pack to see what happens
2011-12-24T00:17:11 < jpa-> oh yeah
2011-12-24T00:20:34 < sourcebox> Got the following error "Error: Data length doesn't have a 32 bit alignment: +1 byte."
2011-12-24T00:24:47 < sourcebox> Flash was erased
2011-12-24T00:25:17 < sourcebox> But no new pages written
2011-12-24T00:34:18 < jpa-> where did you get your linker file?
2011-12-24T00:35:19 < sourcebox> It's one of the example files from the ST firmware library, but I get a similar error when I use an elf file from the stlink examples
2011-12-24T00:43:56 < sourcebox> Is there a chance to get a .bin file that will work correctly?
2011-12-24T00:49:23 < jpa-> you could try reading the default program out and writing it back, if it has not been overwritten yet
2011-12-24T00:49:51 < sourcebox> Tried that, same error :-)
2011-12-24T00:50:50 < sourcebox> File is 16534 bytes which isn't divideable by 32
2011-12-24T00:50:55 < jpa-> did you try another stlink branch already?
2011-12-24T00:51:23 < sourcebox> No, but I'm gonna do that now
2011-12-24T01:01:43 < sourcebox> Ok, seems to write the flash
2011-12-24T01:02:03 < sourcebox> But the original demo isn't running anymore
2011-12-24T01:03:17 < sourcebox> But it's possible that the readout wasn't correct
2011-12-24T01:39:47 < sourcebox> First success, flashing with flash command works but it's very slow
2011-12-24T01:50:07 <+Steffanx> STM should open source their windows too
2011-12-24T01:50:28 <+Steffanx> Maybe that makes the tool for linux/os x/whatever easier
2011-12-24T01:51:04 <+Steffanx> to write
2011-12-24T01:51:10 < BrainDamage> not necessarily
2011-12-24T01:51:31 <+Steffanx> 'maybe' :D :P
2011-12-24T01:51:32 < BrainDamage> if the code is very interwined with windows libs, you're faster starting from scratch
2011-12-24T01:51:55 < BrainDamage> altough I guess having a ref example, for how ugly it can be is better than revernse engineering raw protocols
2011-12-24T01:52:01 <+Steffanx> maybe.. but why is it so slow?
2011-12-24T01:53:42 < sourcebox> Does anybody of you use stlink on linux or os x?
2011-12-24T01:53:53 <+Steffanx> Yes.
2011-12-24T01:54:08 < sourcebox> Is flashing speed ok?
2011-12-24T01:54:28 <+Steffanx> Oh, i think someone who really use it can answer that one
2011-12-24T01:55:17 < sourcebox> I have a 6k blink demo for testing and it took ages via the flash command

2011-12-24T01:57:13 < BrainDamage> linux
2011-12-24T01:57:20 < BrainDamage> yes, it's slow
2011-12-24T01:57:26 < BrainDamage> can take even 1 minute
2011-12-24T01:57:28 <+Steffanx> You know why?
2011-12-24T01:57:31 < sourcebox> Currently OS X
2011-12-24T01:57:43 < sourcebox> But I can test on Linux too
2011-12-24T01:57:44 < BrainDamage> I think it has to do with transfer mode
2011-12-24T01:57:46 < BrainDamage> and block size
2011-12-24T01:57:56 <+Steffanx> think :P
2011-12-24T01:57:57 < BrainDamage> it's not doing a proper bulk transfer
2011-12-24T01:58:36 <+Steffanx> fix that :P
2011-12-24T01:58:47 <+Steffanx> You tried it on os x yet sourcebox ?
2011-12-24T01:59:00 < sourcebox> I'm on OS X now
2011-12-24T01:59:05 <+Steffanx> nvm

2011-12-24T01:59:22 <+Steffanx> You have a stlink/v2 so my following question isn't relevant
2011-12-24T01:59:45 < sourcebox> Yes, the STM32L-DISCOVERY should have the v2
2011-12-24T02:03:57 < sourcebox> I'm new to the platform, so I don't know what would be the best way to get around it. Maybe an external JTAG programmer?
2011-12-24T02:04:20 <+Steffanx> The STlink/v2 is ok.. just fix the driver :)
2011-12-24T02:04:25 <+Steffanx>  /stlink tool
2011-12-24T02:05:05 < BrainDamage> nah, the stlink you got is ok as hardware
2011-12-24T02:05:13 < sourcebox> Unfortunately I'm not experienced enough to do that.
2011-12-24T02:05:14 < BrainDamage> it's the v1 that's horribly broken by design
2011-12-24T02:05:29 <+Steffanx> and v2 is also slow :P
2011-12-24T02:08:14 < sourcebox> According to this thread it shouldn't be much faster on Linux: https://github.com/texane/stlink/issues/32
2011-12-24T02:08:50 < BrainDamage> is the speed issue that problematic?
2011-12-24T02:09:15 < sourcebox> Have to see
2011-12-24T02:10:12 < sourcebox> I think my current project will have about 32k size without any debug code
2011-12-24T02:10:34 < BrainDamage> don't forget also that the tool is improving with the time
2011-12-24T02:10:44 < BrainDamage> I remember few months ago when it didn't work at all for me
2011-12-24T02:11:30 < sourcebox> I'm currently porting from AVR to STM32
2011-12-24T02:11:43 < BrainDamage> same for me actually
2011-12-24T02:11:49 < BrainDamage> I went from atmega to stm32
2011-12-24T02:12:05 < sourcebox> My personal style is to flash quite often
2011-12-24T02:12:22 < BrainDamage> for less price I get a device that is from 20 times more powerful
2011-12-24T02:14:54 < sourcebox> From what I already know, I think it's a good decision
2011-12-24T02:22:39 < jpa-> sourcebox: flashing speed is about 1kB/s for me on linux
2011-12-24T02:22:45 < jpa-> though that is v1 :P
2011-12-24T02:23:22 < sourcebox> 6k took me 23s, that's a liitle slow
2011-12-24T02:23:54 < jpa-> turn off debug messages in gdbserver if you still have them on :)
2011-12-24T02:24:57 < sourcebox> Currently only using the flash command, gdb still makes trouble
2011-12-24T02:25:10 < jpa-> ah, right
2011-12-24T02:26:18 < sourcebox> But I'm gonna check that tomorrow
2011-12-24T02:27:05 <+Steffanx> 1kB/s is @#$%ˆ& s slow jpa-
2011-12-24T02:27:13 <+Steffanx> imgo
2011-12-24T02:27:15 <+Steffanx> *imho
2011-12-24T02:29:28 < sourcebox> But even better than 0.26kB/s :-)
2011-12-24T02:29:38 <+Steffanx> but still too slow for me

2011-12-25T17:30:53 < sourcebox> Hi everybody. I already got a lot of things managed with my new discovery board, but now I got stuck with getting IRQ handlers running.
2011-12-25T17:32:12 < sourcebox> I think something with the startup code isn't working well and the isr vectors aren't correct

2011-12-25T18:08:06 < philpem> sourcebox, are you using the right LD-script and firmware library?
2011-12-25T18:08:25 < philpem> might be useful if you could post your code somewhere for us to look at
2011-12-25T18:09:02 < sourcebox> I think the LD script etc. should be right
2011-12-25T18:09:35 < sourcebox> I'm using the startup_stm32l1xx_md.s file from ST
2011-12-25T18:10:27 < sourcebox> The vectors are defined there, but I don't understand exactly how the are attached to my C functions
2011-12-25T18:11:24 < sourcebox> Is this done by the linker?

2011-12-26T20:29:22 <+Steffanx> Have a nice lunch mr flyback
2011-12-26T20:30:46 <+Steffanx> :)
2011-12-26T20:42:50 < jnosky> I did a tree mod a few years back, used a 68hc05
2011-12-26T20:43:33 < jnosky> Light strings controlled by a triac
2011-12-26T20:44:07 < jnosky> Yers is led?
2011-12-26T20:44:26 < jnosky> oh cool
2011-12-26T20:44:58 < jnosky> I used the hc05 timers and a scavenged IR rcr to use a TV remote control as well
2011-12-26T20:46:30 < jnosky> The fibre optic sounds like a good idea, sounds easier
2011-12-26T20:46:48 < jnosky> I have to arrange my light strings in a particular way
2011-12-26T20:46:56 < jnosky> for best effects
2011-12-26T20:48:20 < jnosky> Color control would be awesome
2011-12-26T20:48:40 < jnosky> Mines like 10 years old already, they didn have shit like that at the time
2011-12-26T20:48:58 < jnosky> The wiring is the bitch tho
2011-12-26T20:59:46 < jnosky> yikes $45 each!
2011-12-26T21:06:49 <+Steffanx> no way
2011-12-26T21:07:10 <+Steffanx> oh, one from sparkfun
2011-12-26T21:07:17 <+Steffanx> That's because you pay hobby tax jnosky :P
2011-12-26T21:07:40 < jnosky> Well ya gotta get em prewired if ya can
2011-12-26T21:07:57 < jnosky> Otherwise its too much like work ;)

2011-12-28T21:38:26 < Thorn> digitalWrite x_x
2011-12-28T21:38:58 < Thorn> does it mean that libraries / drivers written for arduino are usable?
2011-12-28T21:40:47 < sourcebox> Hi everrybody. I have a question regarding USB handling.
2011-12-28T21:40:56 < Laurenceb_> Thorn: i think so
2011-12-28T21:41:09 < Thorn> that could be useful
2011-12-28T21:42:21 < sourcebox> My device features USB but it's optional to use it. Do I have to sense the presence of the host/hub via GPIO or can software detect it?
2011-12-28T21:45:51 < Thorn> the only way I know of is detecting if Vbus is present, you do need a gpio pin for that
2011-12-28T21:46:20 < Laurenceb_> you could setup the pins as gpio inputs
2011-12-28T21:46:26 < Laurenceb_> and use them to detect a cable
2011-12-28T21:46:56 < Laurenceb_> atm i have some hardware with vbus going through a capacitor to trigger an EXTI that resets the device
2011-12-28T21:47:10 < Laurenceb_> theres also a power button on the same pin
2011-12-28T21:47:16 < sourcebox> My main question is, can I leave USB enabled in the code even if it's not connected?
2011-12-28T21:47:23 < Laurenceb_> yes
2011-12-28T21:47:39 < Laurenceb_> but code will fail
2011-12-28T21:48:21 < Laurenceb_> i use the pull up/down resistors to enable one pin to be used as usb detect and power
2011-12-28T21:48:34 < sourcebox> And there's no chance to come around?
2011-12-28T21:48:59 < Laurenceb_> huh?
2011-12-28T21:50:11 < sourcebox> Well I mean then code fails, it's not able to do some kind of "recovering" when host comes back
2011-12-28T21:52:57 < sourcebox> I think i'm gonna use a pin for it, that's the safest method
2011-12-28T21:54:56 < Laurenceb_> oh erm yes
2011-12-28T21:55:08 < Laurenceb_> it should be possible to have the code handle the error
2011-12-28T21:55:27 < Laurenceb_> but its conveivable you might get the hardware into some weird state
2011-12-28T21:55:34 < Laurenceb_> ive seen it happen with i2c
2011-12-28T21:56:46 < sourcebox> I'm still a little confused with the whole USB stuff here. I have a working implementaion for AVR that I'm trying to port
2011-12-28T21:58:25 < Thorn> see UM0424
2011-12-28T21:59:11 < sourcebox> Currently open :-)
2011-12-28T22:00:12 < sourcebox> What I'm missing is some kind of bare minimal example that is just able to connect, send descriptors etc.
2011-12-28T22:00:30 < sourcebox> And doing nothing special
2011-12-28T22:02:22 < sourcebox> Due the UM0424 there should be some templates but I don't find any of them. Only examples
2011-12-28T22:02:49 < Thorn> I've been planning to do just that (both device and PC side with libusb) for quite some time now

2011-12-28T22:08:41 < sourcebox> Currently code gets stuck in a loop of the USB_Istr() interrupt as soon as I setup the IRQ via NVIC_Init().
2011-12-28T22:09:04 < sourcebox> I'm sure I have to clear some flags...
2011-12-28T22:10:42 < Laurenceb_> oh i saw that
2011-12-28T22:10:49 < Laurenceb_> yeah you have to clear it
2011-12-28T22:11:00 < Laurenceb_> i has issues with interrupts pointing in the wrong places
2011-12-28T22:11:07 < Laurenceb_> due to typos in lanchon
2011-12-28T22:13:34 < sourcebox> From the examples, I used the wInterrupt_Mask variable, but I don't understand what it does. Initially it is set to 0, so none of the branches like if (wIstr & ISTR_CTR & wInterrupt_Mask) will be executed
2011-12-28T22:15:39 < Laurenceb_> this is on f103?
2011-12-28T22:15:59 < sourcebox> No on L1xx
2011-12-28T22:16:11 < sourcebox> But it seems to be identical
2011-12-28T22:16:28 < sourcebox> Only connectivity line is different
2011-12-28T22:17:13 < Laurenceb_> hmm its been a while since i did this

2011-12-28T22:21:07 < sourcebox> Did you start from the Mass_Storage example?
2011-12-28T22:21:33 < Laurenceb_> yes

2011-12-28T22:22:51 < Laurenceb_> are you using lanchon?
2011-12-28T22:23:19 < sourcebox> My "problem" is, I really want to understand what's going on not just copy anything.
2011-12-28T22:23:27 < Laurenceb_> oh
2011-12-28T22:23:34 < Laurenceb_> i cant help you much :P
2011-12-28T22:23:37 < sourcebox> But USB is hard stuff
2011-12-28T22:23:45 < sourcebox> No offense to you
2011-12-28T22:23:45 < karlp> have you used usb on other devices?
2011-12-28T22:24:06 < karlp> are you mor elooking for advince on usb on stm32, or is this your first adventure with usb at all?
2011-12-28T22:24:14 < sourcebox> I'm quite new to STM32 but I did it successfully on AVR
2011-12-28T22:24:28 < karlp> usb parts, like the 32u4?
2011-12-28T22:24:33 < sourcebox> Yes
2011-12-28T22:24:49 < sourcebox> I didn't use LUFA but my own code
2011-12-28T22:24:53 < karlp> were you using somethin glike lufa, or
2011-12-28T22:24:56 < karlp> ok, that answers that :)
2011-12-28T22:25:06 < karlp> ok, then it sounds like you should have a decent understanding of how usb works,
2011-12-28T22:25:14 < karlp> so it's just the stm32 specifics
2011-12-28T22:25:24 < sourcebox> So I have a basic knowledge how USB works
2011-12-28T22:25:31 < sourcebox> Yes
2011-12-28T22:25:52 < karlp> the best advice I can give from my experiemtns so far (I'm pretty new to stm32 too) is that when you think you've turned on all the clocks you need, think again, and go turn on more clocks.
2011-12-28T22:26:26 < sourcebox> E.g. the endpoints: on AVR I use 2 endpoints, one for TX and one for RX
2011-12-28T22:26:38 < Laurenceb_> lol karlp
2011-12-28T22:26:45 < sourcebox> On STM32, there is this bidirectional stuff
2011-12-28T22:27:01 < sourcebox> Is this mandantory?
2011-12-28T22:27:50 < sourcebox> So do I have to setup just one EP or can I do it like before?
2011-12-28T22:32:26 < karlp> I would think you could do it like you did before,
2011-12-28T22:32:37 < karlp> bloody hell, openocd docs are terrible.
2011-12-28T22:33:12 < AK6L> hehe
2011-12-28T22:33:25 < AK6L> hey karlp, i figured out why my STM32F4 Discovery board was freaking out.
2011-12-28T22:33:32 < karlp> yeah? great news!
2011-12-28T22:33:34 < sourcebox> BTW I use your fork of stlink karlp
2011-12-28T22:33:35 < AK6L> GPIOA_MODER's reset value is *not* 0x0
2011-12-28T22:33:46 < AK6L> and the board gets *pissed* if you set it to 0x0.
2011-12-28T22:34:00 < karlp> what was setting it to 0?
2011-12-28T22:34:08 < AK6L> it's like 0xA8000000 or something, and i think the 3 high pins are related to the stlink interface
2011-12-28T22:34:09 < karlp> I still don't see why unplyugging and replugging didn't fix that
2011-12-28T22:34:11 < AK6L> my code was :P
2011-12-28T22:34:15 < karlp> right :)
2011-12-28T22:34:26 < karlp> but how did rebooting into windows fix it?
2011-12-28T22:34:47 < AK6L> karlp: it didn't; the windows utility was able to bring up the board in DFU mode, i guess
2011-12-28T22:35:07 < AK6L> karlp: reflashing under linux with the code from github worked fine once i jumpered BOOT0 and BOOT1
2011-12-28T22:35:12 < karlp> hmm,
2011-12-28T22:35:26 < karlp> fair enough
2011-12-28T22:35:49 < Laurenceb_> is dfu mode in the rom?
2011-12-28T22:35:56 < Laurenceb_> like the serial loader
2011-12-28T22:35:56 < karlp> there's a few changes filtering into github main now, hopefully should be a worthwhile new release aroun dnew years
2011-12-28T22:35:59 < AK6L> before, when i was replugging the board into USB, i think the code (which was resetting GPIOA_MODER) kicked off right away thus breaking the ST-Link/v2 interface
2011-12-28T22:36:01 < karlp> yeah, f4 has dfu built in
2011-12-28T22:36:07 < Laurenceb_> nice
2011-12-28T22:36:17 < karlp> there's a nice doc with all the available built in bootloaders
2011-12-28T22:36:24 < AK6L> so the stlink github code couldn't talk to the chip until i jumpered the BOOT bits.
2011-12-28T22:36:34 < AK6L> moral of the story: herp derp read the docs, dumbass.
2011-12-28T22:36:40 < AK6L> :)
2011-12-28T22:36:43 < karlp> heh
2011-12-28T22:37:14 < karlp> someone ported a chunk of <unknown date/rev> texane/stlink code into openocd, to support th estlinkv2 at least
2011-12-28T22:37:25 < karlp> I'm trying to build and run openocd with the patches for the first time
2011-12-28T22:37:31 < karlp> it's less than pleasant so far
2011-12-28T22:38:06 < AK6L> from what i gather, running openocd at all is less than pleasant ;)
2011-12-28T22:38:24 < karlp> it seeeems like they have a better/more fully featured gdb server
2011-12-28T22:38:38 < karlp> and some of the other bugs that the texane/stlink project doesn't really want to have to deal with sorted out
2011-12-28T22:39:10 < AK6L> gotcha
2011-12-28T22:39:25 < karlp> so if it can be made to work,
2011-12-28T22:39:34 <+Steffann> i dont understand why you didn't that in the first place karlp
2011-12-28T22:39:36 < karlp> then isntead of putting in time on docs and bugfixes on stlink, I can just improve openocd instead.
2011-12-28T22:39:45 <+Steffann> Give openocd support for the stlink
2011-12-28T22:39:47 < karlp> Steffann: a) openocd didn't support swd at all.
2011-12-28T22:39:54 < karlp> openocd was a much bigger code base
2011-12-28T22:39:59 < karlp> I didn't write stlink :)
2011-12-28T22:40:01 <+Steffann> it did with a patch of versaloon
2011-12-28T22:40:19 < karlp> maybe, but openocd is ahuge undocumented mess with patches dangling in mailing lists
2011-12-28T22:40:27 < karlp> and I personally had NO idea where to even start
2011-12-28T22:40:40 < karlp> with stlink, I could actually start doing something
2011-12-28T22:40:47 <+Steffann> pebkac :P
2011-12-28T22:40:56 < karlp> I didn't see you doing it
2011-12-28T22:41:21 < sourcebox> I wish you all the best on getting it to work
2011-12-28T22:41:38 <+Steffann> I didn't need it karlp
2011-12-28T22:41:55 <+Steffann> I did.. a few days
2011-12-28T22:41:59 < karlp> the person who has submitted this patch to openocd hasn't turned up here at all, nor ever forked or commented on the stlink code either to the best of my understanding.
2011-12-28T22:42:04 <+Steffann> but i didn't even have the time to do it
2011-12-28T22:42:14 < sourcebox> Currently I use stlink on OS X, but I can get only 0.25kB/s speed which is very frustrating
2011-12-28T22:42:44 < sourcebox> Debug code of my USB project is corrently about 45k
2011-12-28T22:43:08 < karlp> that's something else to hopefully get from openocd, more people for perf stuff
2011-12-28T22:43:23 < karlp> sourcebox: there's very very very few people usin gthe L1xx targets
2011-12-28T22:43:26 < karlp> so it's very slow
2011-12-28T22:43:30 < karlp> it does 16bits at at time,
2011-12-28T22:43:44 < karlp> it needs to switch to half page writes
2011-12-28T22:43:51 < sourcebox> Ok
2011-12-28T22:44:07 < karlp> there's a little bit of code to try and do that, but it needs testing and bugfixing.
2011-12-28T22:44:22 < karlp> I use the L1 too, but so far I'm  just dealiing with it, and trying to stop things from breaking.
2011-12-28T22:44:44 < karlp> the openocd patch only works with the stlinkv2 anyway, so until it works with the v1, stlink still lives on.
2011-12-28T22:44:56 < sourcebox> The L1 is perfect for my needs because I need USB and DACs
2011-12-28T22:45:03 < karlp> yeah, it's a neat chip
2011-12-28T22:45:30 < sourcebox> To get the same on F1 you have to use a much bigger chip
2011-12-28T23:00:52 < sourcebox> Well I think I have to find a better solution for flashing since doing USB code is a lot of trial and error
2011-12-28T23:11:30 < karlp> you can try running from ram....
2011-12-28T23:11:47 < sourcebox> Only 16k
2011-12-28T23:12:38 < karlp> you should be able to make a subset of code that just implements your usb features?
2011-12-28T23:12:57 < karlp> or, buy an expesnive jtag programmer and tools...
2011-12-28T23:13:26 < sourcebox> Maybe but even the firmware libs are too big when compiled with debug code
2011-12-28T23:14:00 < sourcebox> What do you think about the versaloon project?
2011-12-28T23:14:10 < karlp> last I looked I felt it was like openocd
2011-12-28T23:14:13 < karlp> it might be great,
2011-12-28T23:14:19 < karlp> but I can't tell from their docs
2011-12-28T23:14:55 < sourcebox> I have an unused VL discovery here which I can flash with their code
2011-12-28T23:16:46 < sourcebox> Possibly better than the stlink v1 it features :-)
2011-12-28T23:19:32 < karlp> perhaps,
2011-12-28T23:19:41 < karlp> the stlinkv1, these days, is just as capable as the v2,
2011-12-28T23:20:19 < karlp> it was just a matter of getting linux and osx to try and stop  loading the usb mass storage drivers for it.
2011-12-28T23:20:29 < karlp> the v1 doesn't have any SWV/SWO support,
2011-12-28T23:20:45 < karlp> but none of the free tools support that with the v2 yet either to th ebest of my knowledge.
2011-12-28T23:20:53 < karlp> (though, eventually, that will be the key feature)
2011-12-28T23:25:38 < Laurenceb_> yeah we need it asap
2011-12-28T23:36:34 < sourcebox> Firmware needs a "enable all clocks" function

2011-12-29T00:47:59 < Xeo_it> hello
2011-12-29T00:53:49 < sourcebox> I came to the conclusion that getting stuck in the USB IRQ has to do something with the pullup
2011-12-29T00:54:44 < sourcebox> I the examples they setup the pullup first, then init USB interrupt
2011-12-29T00:55:24 < sourcebox> But as I understand the USB specs, this is not way it should be done

2011-12-29T01:29:10 < Laurenceb_> oh yeah
2011-12-29T01:29:15 < Laurenceb_> its due to bus error
2011-12-29T01:29:34 < Laurenceb_> i had that issue due to poorly designed external matching network
2011-12-29T01:36:47 < sourcebox> What I try to do is to setup the USB init at boot but let the IRQ disabled. Then I check for the host regularly. If it's connected, the enable the IRQ and the D+ pullup. Hope this works as expected.
2011-12-29T01:43:56 < sourcebox> But there's still one issue: what if the device is connected to a hub, but host is off. VBUS is still delivered then.
2011-12-29T01:50:48 < philpem> karlp, SWV/SWO?
2011-12-29T01:51:48 <+Steffann> Debug output over the programmer philpem
2011-12-29T01:52:18 <+Steffann> So you can debug using SWD and printf's :)
2011-12-29T01:52:28 < philpem> O_O
2011-12-29T01:52:43 < philpem> Now that would be nice. I could free up the USB port I'm using for the Bus Pirate :)
2011-12-29T01:52:50 <+Steffann> :)
2011-12-29T01:53:21 <+Steffann> The stlink/v2 seems to have a pin for it and some closed source IDE's also seem to support it
2011-12-29T01:53:38 < philpem> Guess I'd have to buy an ST-link and attach it to the VL-discovery though (or find a way to attach the STM32-discovery programmer to the VL)
2011-12-29T01:53:51 < philpem> or just use SWV/SWO on the target board
2011-12-29T01:53:57 < philpem> still learning atm :)
2011-12-29T01:54:27 < philpem> i've got GPIOs toggling but that's it. really needed a number cruncher for this project, but getting my head around all the different registers and how everything works is a pain.
2011-12-29T01:54:51 < philpem> reminds me of when I learned how to use the PIC16C84 as a wee' lad o' but 12 years age :P
2011-12-29T01:55:07 <+Steffann> Huh? VL discovery <> STM32-discovery?!
2011-12-29T01:55:43 < philpem> sorry, L-discovery
2011-12-29T01:56:01 < philpem> the STM32L Discovery has an ST-Link/V2 onboard, the STM32VL-Discovery has a /V1
2011-12-29T01:56:15 <+Steffann> Yeah, both work very well with the stlink tool from texane
2011-12-29T01:56:21 <+Steffann> Or at least, they should wokr :)

2011-12-29T01:57:37 < sourcebox> They still sell it for that
2011-12-29T01:58:12 < philpem> Steffann, I've had trouble with Texane's branch... seems to be a bit hit and miss at the moment
2011-12-29T01:58:40 < philpem> Mmm, 68EC000... 68k on an 8bit bus was it (or was that the 68008?)
2011-12-29T01:59:06 < Laurenceb_> that seems to be insulting the scottish
2011-12-29T01:59:21 <+Steffann> Oh, that branch seems to break all the time philpem

2011-12-29T20:43:27 < feurig> dumb question.
2011-12-29T20:45:33 < feurig> so I have a chunk of code that sets up a vectored interrupt for the uart0
2011-12-29T20:45:41 < feurig> 		VICIntSelect &= ~0x00000040; //~VIC_IntSelect_UART0;
2011-12-29T20:45:41 < feurig> 		VICIntEnable |= 0x00000040;  //VIC_IntEnable_UART0;
2011-12-29T20:45:41 < feurig> 		VICVectCntl1 = 0x26;
2011-12-29T20:45:41 < feurig> 		VICVectAddr1 = (unsigned int)UART0ISR;
2011-12-29T20:45:43 < feurig> 		U0IER = 0x01;
2011-12-29T20:46:27 < feurig> and I want to add a second vector for uart1
2011-12-29T20:47:45 < feurig> I understand what goes into VICIntSelect,Enable,Address and that I need to set U1IER but I dont understand what goes into the VICVectCntlN part
2011-12-29T20:48:21 < feurig> Tom_itx: ?
2011-12-29T20:52:14 < feurig> I mean the 6 is the channel for uart0 but where does the upper part come from?
2011-12-29T20:54:15  * feurig looks for the enable bit part.
2011-12-29T20:56:51 < feurig> nevermind the 2 is the enable.
2011-12-29T20:57:00 < feurig> #define VIC_VectCntl_ENABLE     (0x00000020)
2011-12-29T20:57:10 < feurig> thanks.

2011-12-30T17:50:40 < Thorn> all 10 boards have markings on the edge, does that mean they did 100% electrical test? I didn't pay for that
2011-12-30T17:52:05 < Thorn> new year gift? :)
2011-12-30T17:57:06 < jpa-> :P

2011-12-30T20:15:35 < Tom_itx> seeed's quality lacks from other cheap chinese vendors
2011-12-30T20:15:53 <+Steffann> No way
2011-12-30T20:16:23 <+Steffann> Maybe years ago when you tried it..
2011-12-30T20:16:34 < Tom_itx> it hasn't been that long
2011-12-30T20:16:53 <+Steffann> it was 100% perfect for me
2011-12-30T20:17:09 < Tom_itx> i'm sure they get it right alot of the time
2011-12-30T20:18:46 <+Steffann> itead does 4 layers now.. i wonder how good that is
2011-12-30T20:19:27 < Tom_itx> i think their quality is worse than seeed
2011-12-30T20:19:42 <+Steffann> Probably not
2011-12-30T20:19:56 <+Steffann> The quality of seeed is perfect, for me
2011-12-30T20:20:10 < Tom_itx> go forth and be happy then
2011-12-30T20:20:34 <+Steffann> Don't need 4 layer
2011-12-30T20:20:44 <+Steffann> I mean, the quality from that dorkbot isn't better
2011-12-30T20:21:10 < Tom_itx> the mask is heavier for one thing
2011-12-30T20:21:33 < Tom_itx> alot tougher for hand soldering than you get with alot of chinese vendors
2011-12-30T20:21:53 < Tom_itx> their mask is fine for production but not nearly as good for hand soldering
2011-12-30T20:22:15 <+Steffann> Who cares about that? :)
2011-12-30T20:22:27 <+Steffann> Who uses seeed for production pcb's anyway?
2011-12-30T20:22:42 < Tom_itx> i'm saying the mask can be thinner for production
2011-12-30T20:22:50 <+Steffann> oh ok :P
2011-12-30T20:24:30 < karlp> Thorn: I thought I read somewhere recently that seeed was upgrading to 100% etest as standard
2011-12-30T20:25:01 <+Steffann> Yeah, i read something about that too
2011-12-30T20:25:07 < Tom_itx> i dunno
2011-12-30T20:25:17 <+Steffann> Or sometimes they even do it for you
2011-12-30T20:25:42 < Tom_itx> i get mine back from GP and they all have divits on the pads where they were tested whether you ask for testing or not
2011-12-30T20:25:50 < Tom_itx> they just don't send you the results
2011-12-30T20:26:02 < Tom_itx> but they do mark some as bad and send you extra board material
2011-12-30T20:26:03 <+Steffann> lol
2011-12-30T20:26:09 <+Steffann> like seeed
2011-12-30T20:28:12 < Tom_itx> http://tom-itx.dyndns.org:81/~webpage/scope/DSC_0002.JPG
2011-12-30T20:28:22 < Tom_itx> that was one of the worst i've come across
2011-12-30T20:28:34 < Tom_itx> the 2 traces were joined for about 1/4" or so
2011-12-30T20:29:39 <+Steffann> I've seen that boar before..
2011-12-30T20:29:46 <+Steffann> but one bad board doesn't make seeed bad
2011-12-30T20:29:53 < Tom_itx> no
2011-12-30T20:29:58 < Tom_itx> i've seen others
2011-12-30T20:30:12 < Tom_itx> if i had to, i'd use them
2011-12-30T20:30:27 <+Steffann> Ofcouse, but I've also seen many good ones
2011-12-30T20:30:37 < Tom_itx> i'd use them over itead
2011-12-30T20:30:58 <+Steffann> For the few board i got from seeed the quality is as good as an @#$% expensive service
2011-12-30T20:31:56 <+Steffann> So i'll use them until they screw up :0
2011-12-30T20:31:58 <+Steffann> :)
2011-12-30T20:32:15 < karlp> is GP gold phoenix?
2011-12-30T20:32:21 <+Steffann> That image is from 2 years ago..

2011-12-30T21:53:32 <+Steffann> You?
2011-12-30T21:53:40 < jpa-> same, same
2011-12-30T21:53:51 < jpa-> probably just staying at home and watching from window
2011-12-30T21:54:43 <+Steffann> LOL :P
2011-12-30T21:54:49 <+Steffann> I'm not THAT bad
2011-12-30T21:54:56 < jpa-> atleast i have a view :P
2011-12-30T21:55:49 <+Steffann> I wouldn't be surprised when you are serious
2011-12-30T21:56:34 < jpa-> http://koti.kapsi.fi/jpa/stuff/pix/pirkkala_valo.jpg
2011-12-30T21:56:47 <+Steffann> Yeah, nice view
2011-12-30T21:56:54 <+Steffann> That's the light beam?
2011-12-30T21:56:56 <+Steffann> *what's
2011-12-30T21:57:09 < jpa-> i don't know :D
2011-12-30T21:57:13 < jpa-> that is why i took the photo
2011-12-30T21:57:17 <+Steffann> Aah :D
2011-12-30T21:57:19 < jpa-> i think they were looking for me :)
2011-12-30T22:01:38 < jpa-> but where are you going to practise your boredness?
2011-12-30T22:02:33 <+Steffann> My room ofcourse
2011-12-30T22:02:36 <+Steffann> Behind my pc
2011-12-30T22:02:38 <+Steffann> Duh
2011-12-30T22:02:50 <+Steffann> in front of my pc :P
2011-12-30T22:03:22 < jpa-> :)
2011-12-30T22:03:39 <+Steffann> Otherwise you'll be alone here
2011-12-30T22:05:36 < jpa-> true
2011-12-30T22:05:49 < jpa-> i should get coding, but i've been too bored to
2011-12-30T22:06:02 <+Steffann> coding what?
2011-12-30T22:06:26 < jpa-> some stuff for libfixmath
2011-12-30T22:06:39 < jpa-> then finish documenting my matrix library
2011-12-30T22:06:41 <+Steffann> oh I used that lib once
2011-12-30T22:06:44 < jpa-> then make a kalman filter
2011-12-30T22:06:54 < jpa-> then integrate it to boat
2011-12-30T22:07:05 < jpa-> then fix the hull
2011-12-30T22:07:34 <+Steffann> You are really that into math?
2011-12-30T22:08:10 < jpa-> sure
2011-12-30T22:08:30 < jpa-> i actually enjoy it
2011-12-30T22:09:04 <+Steffann> math ?
2011-12-30T22:09:37 < jpa-> yeah
2011-12-30T22:11:14 <+Steffann> How can one enjoy that?
2011-12-30T22:11:32 < jpa-> https://svn.kapsi.fi/jpa/libfixmath/libfixmatrix/  what i have so far
2011-12-30T22:12:58 <+Steffann> That's not much
2011-12-30T22:13:05 <+Steffann> :)
2011-12-30T22:13:13 < jpa-> true, but all i need
2011-12-30T22:14:20 < jpa-> (all the matrix algebra necessary for kalman filters)
2011-12-30T22:14:34 <+Steffann> And not that difficult at all
2011-12-30T22:14:46 <+Steffann> Kalman is more difficult, at least… I do understand it :)
2011-12-30T22:16:31 < jpa-> most of the stuff is dead simple; qr decomposition is probably the most complex
2011-12-30T22:17:17 < jpa-> but it involves a lot of testing, whereas kalman filter is just a few simple formulas involving matrices
2011-12-30T22:17:37 <+Steffann> Maybe, but I don't understand what they say on wikipedia :P
2011-12-30T22:17:47 < jpa-> wikipedia explanation sucks, yeah :)
2011-12-30T22:18:00 < jpa-> fortunately our uni had a course on it
2011-12-30T22:18:10 <+Steffann> I've never seen a good/understandable explanation on the web
2011-12-30T22:18:26 <+Steffann> Maybe i've to search for osmething on the mit open courseware
2011-12-30T22:21:51 < jpa-> model the prior and posterior distributions using multidimensional normal distributions; have a linear model for the state transition and measurement model; use them to compute the new state estimate based on old estimate and measurements :P
2011-12-30T22:22:11 <+Steffann> YEAH
2011-12-30T22:23:08 < jpa-> so what part is the problem? ,)
2011-12-30T22:23:30 <+Steffann> kalman :)
2011-12-30T22:24:36 < jpa-> that is just bayes formula applied to the distributions :)
2011-12-30T22:24:38 < Laurenceb_> KALLLMAAAAAAAAAAAAAAAANNNNNNNNNNN!!!!!
2011-12-30T22:24:52 < Laurenceb_> the solution to and cause of all of lifes problems
2011-12-30T22:28:20 <+Steffann> so Laurenceb_ gets it?

2011-12-31T16:30:25 < jpa-> Steffann: ufo landing site, filled with water
2011-12-31T16:31:12 <+Steffann> ok..
2011-12-31T16:31:33 <+Steffann> That watertower is still in use?
2011-12-31T16:33:25 < jpa-> yeah
2011-12-31T17:23:22 < Thorn> homemade pcb with solder mask http://we.easyelectronics.ru/evsi/yet-another-development-board-ili-mini64.html
2011-12-31T17:24:44 <+Steffann> In russian :(
2011-12-31T17:25:15 < Thorn> with pictures
2011-12-31T17:25:48 < Thorn> there's not much details on the technology anyway
2011-12-31T17:26:02 < Thorn> maybe there's some other article
2011-12-31T17:26:05 <+Steffann> Where's the website about? Or is it your blog?
2011-12-31T17:26:17 < jpa-> the plating is more interesting than the solder mask
2011-12-31T17:26:20 < Thorn> nope not mine
2011-12-31T17:27:07 <+Steffann> gold plating?
2011-12-31T17:27:08 < Thorn> it's a community with a blog hosting among other things
2011-12-31T17:28:54 < Thorn> this is what he used for tinning http://item.taobao.com/item.htm?id=8775294876
2011-12-31T17:29:28 <+Steffann> it sucks my russian is too bad
2011-12-31T17:30:34 < jpa-> the through-hole plating, i meant
2011-12-31T17:30:49 < Thorn> ah. there's none
2011-12-31T17:30:57 < Thorn> the pcb is single layer
2011-12-31T17:31:20 < jpa-> ah, missed that
