2026-02-01T01:46:40 < mawk> I was finally able to dump my office tag
2026-02-01T01:47:08 < mawk> I had to purposefully fuck the antenna by moving away the resonant frequency, then put a metal coaster behind the tag for additional RF magic
2026-02-01T01:47:33 < mawk> and I found the tag password and was able to read the contents, BDF5E846
2026-02-01T01:48:08 < mawk> then some maths magic with the contents of the tag and I can copy that to another tag which should be accepted by the reader if it has the default configuration 
2026-02-01T01:49:00 < mawk> I think the shitty capricious antenna in the tag is on purpose, there's no way otherwise 
2026-02-01T01:49:27 < mawk> even the legitimate reader can't read it properly sometimes, you have to jingle metal keys behind the tag to get it to read

2026-02-01T09:34:33 < jpa-> eh, is gcc and the internet gaslighting me or is it really not-quite-proper to call isspace() on a char?
2026-02-01T09:45:37 < lemmi> maybe read the "CAVEATS" section in the manpage
2026-02-01T09:46:32 < lemmi> has to do with isspace taking ints instead of char and sign extensions
2026-02-01T10:06:14 < jpa-> yeah, but how stupid is that
2026-02-01T10:06:30 < jpa-> it's not like it couldn't internally do   if (c < 0) c = (unsigned char)c
2026-02-01T10:07:19 < jpa-> but no, it will read out of buffer, because it's the C way to do things!
2026-02-01T10:07:34 < jpa-> and let's decide randomly per platform whether char is signed or not
2026-02-01T10:11:16 < lemmi> oh, i'm not defending this. i find it at least as stupid
2026-02-01T10:11:28 < lemmi> the whole c stdlib is a mess. 
2026-02-01T10:11:32 < jpa-> i know, i'm just ranting :)
2026-02-01T10:11:46 < jpa-> 20 years of C and i'm still learning new stupidness
2026-02-01T10:26:00 < zyp> learning stupidness instead of learning rust is your choice :)
2026-02-01T10:27:02 < jpa-> if i rant about C, everyone is my friend: "yeah, it's totally stupid, we understand you"
2026-02-01T10:27:39 < jpa-> if i rant about rust, everyone is my enemy: "you are doing things wrong, you don't understand the language, you should do it with boxes or without boxes or with borrowing or if you are so stupid, just RC it all!"
2026-02-01T10:31:54 < zyp> :D
2026-02-01T10:33:31 < zyp> the problem with rust is that you don't get to rant about it, you have to rave about how everybody else should switch to it too
2026-02-01T10:51:32 < qyx> idk what's the proper english name for it, we call it crowd psychosis
2026-02-01T10:52:12 < qyx> thats exactly what's happening with rust

2026-02-01T11:19:16 < mawk> jpa- I always set char to unsigned for good measure -funsigned-char
2026-02-01T11:21:32 < BrainDamage> fun signed chars
2026-02-01T11:21:52 < BrainDamage> too bad the other flag is not unfun

2026-02-01T12:26:10 < nohit> jpa-: there is the middle way, its called C++
2026-02-01T12:27:23 < nohit> i wouldnt even touch C anymore, if it was up to me
2026-02-01T12:28:32 < zyp> the issue with C++ is that the people resisting change doesn't want that either
2026-02-01T12:28:46 < zyp> and if you don't have people resisting change, you might as well jump to rust right away
2026-02-01T12:32:24 < zyp> I used to be on the other side of this fence, been doing C++ for decades, used to think «rust looks nice, but I don't really want to learn it, C++ has a bunch of the same advantages and I hope it eventually gets more»
2026-02-01T12:34:56 < nohit> rust might be a good thing in the future, but currently its "market share" is tiny and i havent seen a single embedded job ad in finland that is looking for rust developers
2026-02-01T12:39:16 < mawk> I don't want C++
2026-02-01T12:39:21 < mawk> it's too complicated to be good at it
2026-02-01T12:39:29 < mawk> I can't trust my colleagues with it
2026-02-01T12:39:32 < mawk> or maybe myself
2026-02-01T12:39:41 < mawk> C is nice and simple
2026-02-01T12:39:53 < mawk> bugs are straightforward to find
2026-02-01T12:41:06 < zyp> from my perspective, the embedded rust world seems further along than embedded c++
2026-02-01T12:41:33 < nohit> if you look at the numbers, its not
2026-02-01T12:41:50 < nohit> maybe the tooling is, i dont know
2026-02-01T12:42:17 < zyp> I'm talking about infrastructure
2026-02-01T12:42:21 < nohit> yeah
2026-02-01T12:43:26 < zyp> are there any mature embedded C++20 coroutine platforms yet?
2026-02-01T12:46:09 < zyp> I wrote my own: https://github.com/zyp/laks/tree/main/async
2026-02-01T12:47:43 < zyp> turns out the rust world made something that already does more or less everything I wanted with that: https://github.com/embassy-rs/embassy
2026-02-01T12:48:49 < zyp> I wrote an efficient embedded logging framework for C++: https://github.com/zyp/smolt, guess what, rust world already did: https://github.com/knurling-rs/defmt
2026-02-01T12:50:18 < zyp> coming to rust was a bit of «fuck, everything I ever did is now obsolete because it's already done better in rust»
2026-02-01T12:52:05 < zyp> I also wrote a build system specifically to support c++20 modules: https://github.com/zyp/erect
2026-02-01T12:52:19 < zyp> not gonna need that if there's no point writing C++ anymore
2026-02-01T12:53:30 < nohit> there's one major point, money
2026-02-01T12:55:48 < nohit> the huge industry isnt just gonna change over night because some hipsters came up with a better programming langueage
2026-02-01T12:55:53 < zyp> yeah, so I've traditionally used C in my day job, because of people resisting change
2026-02-01T12:56:43 < zyp> about a year ago, we started talking about doing C++20 coroutines
2026-02-01T12:57:54 < zyp> coworker was doing some prototyping with that, integrating a coroutine executor in our existing platform
2026-02-01T12:59:07 < zyp> ran into some of the common footguns where you pass a reference to a stack variable into a coroutine and then return before it completes
2026-02-01T12:59:51 < jpa-> i don't dare recommend rust to clients because i know that then they'll have even harder time getting anyone else maintain it
2026-02-01T13:00:13 < zyp> he asked me if there were a way to catch that at compile time, I joked «not without switching to rust, I think»
2026-02-01T13:00:20 < jpa-> good embedded C coders are already rare enough, embedded rust coders much more so; and desktop/web rust coder just isn't enough
2026-02-01T13:00:40 < zyp> a couple of days later he drops by my office again «actually, we shouldn't just switch to rust instead of C++?»
2026-02-01T13:01:41 < zyp> and so I'm now writing embedded rust for a living :p
2026-02-01T13:01:51 < jpa-> cool

2026-02-01T17:12:34 < qyx> zyp: a coroutine is not something I would even consider for embedded to start with
2026-02-01T17:12:50 < qyx> tbh, even for non-embedded
2026-02-01T17:14:17 < qyx> I am not young enough for that stuff
2026-02-01T17:35:57 < zyp> coroutines are awesome

2026-02-01T18:46:00 < veverak> qyx: how else do you want to express complex asynchronous process? :)
2026-02-01T18:46:28 < veverak> the "do x, way for reply, do y, wait for reply, do z, wait for reply" chain of events
2026-02-01T18:47:39 < veverak> state machine can create tons of bloat and state to manually manage, creating thread for any such thing might be pain in the biscuit in multiple other ways (altho it is preferable way I guess)
2026-02-01T18:47:58 < veverak> zyp: just FYI: you can block C++20 coroutines from accepting references, is not magic (or reference-like type)
2026-02-01T18:48:05 < veverak> (at compile time0
2026-02-01T18:49:38 < zyp> yeah, let's ban all references and enforce everything gets passed by value since you can't ensure references live long enough, good idea
2026-02-01T18:49:50 < veverak> it has it's downsides ;)
2026-02-01T19:01:46 < mawk> I was at the wolfboot stand too
2026-02-01T19:01:53 < mawk> it's a secure bootloader by the wolfssl guys
2026-02-01T19:01:57 < mawk> sounds interesting 
2026-02-01T19:02:03 < mawk> more than the shitty ST SBSFU
2026-02-01T19:02:17 < mawk> too bad we already paid a consultant to implement SBSFU
2026-02-01T19:04:01 < qyx> veverak: fully synchronously, nice, easy to understand for first year students, fully deterministic, linear program flow, etc.
2026-02-01T19:04:43 < qyx> no shitty FSMs you have to track and discover their internals, that's for academic guys drawing their state diagrams
2026-02-01T19:05:48 < qyx> some things are not worth reinventing
2026-02-01T19:06:34 < mawk> I do a nice adjacency matrix when I make a state machine
2026-02-01T19:06:44 < mawk> then check at runtime the state transition 
2026-02-01T19:06:50 < mawk> and you can just plot the graph

2026-02-01T20:13:05 < veverak> qyx: except that I have system where multiple such processes occurs at once
2026-02-01T20:13:14 < veverak> so full synchronous is not really that great
2026-02-01T20:13:53 < veverak> anyway, sometimes FSM makes sense, sometimes threads make sense, coroutines are just nice third alternative (that I personally find easier to reason about)

2026-02-02T21:51:45 < jpa-> heh, gave gemini, claude and chatgpt a go at reviewing what i have for nanopb-1.0 so far.. first gemini insisted that i shouldn't modify nanopb, but i adjusted the prompt and then it said i should remove configuration options and backwards compatibility; claude thinks i should duplicate all code for const & non-const version; chatgpt free version couldn't handle full code, so it only gave some basic 
2026-02-02T21:51:45 < jpa-> suggestions based on headers
2026-02-02T21:52:42 < jpa-> they all seem to agree that i should use error codes instead of true/false return + diagnostic errmsg; but i think i'll stay stubborn and consider that it doesn't really matter in what way a message is corrupted
2026-02-02T21:53:09 < aandrew> I had some fun with nanopb, trying to get it to build cleanly inside a cmake project without host dependencies. what a fucking mess
2026-02-02T21:53:40 < jpa-> glad to make your day a little better!
2026-02-02T21:54:35 < jpa-> (i *think* something should be done about the cmake stuff, there are two somewhat independent cmake-thingies in there that were contributed by different people, and i'm total cmake-noob myself)
2026-02-02T21:55:01 < aandrew> I basically have to create a fucking venv from inside the CMakeLists.txt
2026-02-02T21:55:09 < aandrew> yeah I know almost nothing about cmake
2026-02-02T21:55:25 < jpa-> yeah, host python-protobuf dependency is a pain
2026-02-02T21:56:07 < jpa-> i just don't know what to possibly replace it with, python is still the easiest cross-platform solution and i think the problem would be pretty much the same with any python protobuf library
2026-02-02T21:56:40 < aandrew> heh from my CMakeLists.txt:
2026-02-02T21:56:41 < aandrew> # now call nanopb_generate_cpp() to generate the .pb.c and .pb.h files
2026-02-02T21:56:41 < aandrew> # this will call the host's protoc, and unfortunately it won't use the correct python path (the one in the venv)
2026-02-02T21:56:45 < aandrew> # so we have to fuck around a little. FindNanopb.cmake has a way to prefix the protoc command (intended to be
2026-02-02T21:56:48 < aandrew> # used for MSVC) but we can (ab)use it to append the venv's bin/ to the path so the host's protoc will use the
2026-02-02T21:56:51 < aandrew> # python environment we created above
2026-02-02T21:56:53 < aandrew> list(APPEND CMAKE_MODULE_PATH ${CMAKE_SOURCE_DIR}/nanopb/extra)
2026-02-02T21:56:56 < aandrew> find_package(Nanopb REQUIRED)
2026-02-02T21:56:58 < aandrew> set(CUSTOM_COMMAND_PREFIX ${CMAKE_COMMAND} -E env PATH=${NANOPB_VENV_DIR}/bin:$ENV{PATH})
2026-02-02T21:57:02 < aandrew> nanopb_generate_cpp(TARGET proto RELPATH meshtastic-pb ${PROTO_FILES})
2026-02-02T21:57:58 < jpa-> possibly the cmake stuff should be changed to just call    "python nanopb_generator.py myproto.proto"  because it is easier to handle paths correctly when it doesn't go through the protoc plugin mechanism
2026-02-02T21:58:19 < jpa-> but then again if i touch the cmake files someone's project will break
2026-02-02T21:58:40 < aandrew> I have no idea... this is working and I'm very leery on changing anything 
2026-02-02T21:58:47 < jpa-> exactly :)
2026-02-02T22:01:07 < jpa-> also i still don't understand protobuf editions so i haven't done anything about it
2026-02-02T22:11:45 < aandrew> yeah me neither. I kind of get it working then leave it the fuck alone
2026-02-02T22:12:11 < aandrew> having a reasonably straightforward way to generate a venv in a cmake project though is nice, I should be able to use this elsewhere
2026-02-02T22:12:35 < aandrew> python's package management is such a fucking pain in the ass. one of the reasons I hate all these "million dependency" languages
2026-02-02T22:12:48 < aandrew> gimme stdc and a few other libraries as I need them and fuck off with the whole ecosystem
2026-02-02T22:12:58 < aandrew> heh I feel like I'm channelling timecop here

2026-02-02T22:22:53 < jpa-> yeah well, i dunno about any plain-C protoc implementation, but if you ever try to compile the standard C++ protoc, you'll wish it was python
2026-02-02T22:30:21 < veverak> and you need .py for that anyway right?
2026-02-02T22:30:29 < veverak> aandrew: the whole generation is not really magic - we wrote our own cmake stuff
2026-02-02T22:30:41 < veverak> making nanopb lib is like 6 lines of cmake
2026-02-02T22:31:17 < veverak> as for the generation function: most of the issues was to find the right python but we wrote it in  a way that it is much more straightfowrard as what is going on in the project, which proved to be valuable in pipeline

2026-02-02T22:36:06 < aandrew> nanopb is plain C is it not? Mind you it's calling google's protoc (on the host) to generate the .c/.h
2026-02-02T22:37:06 < aandrew> veverak: yes, making the nanopb lib is easy, I pasted it above. getting the venv to not be a "manual step" took some doing but now you can clone the repo and it'll create and use the venv as part of the build
2026-02-02T22:38:49 < veverak> woudln't it be easier to run the cmake in some venv?
2026-02-02T22:43:25 < aandrew> that still requires a manual step. I was going for git clone && mkdir foo/build && cd foo/build && cmake .. && cmake
2026-02-02T22:43:58 < aandrew> (yes I know that's a lot of steps, the point is that it follows the normal flow for cmake projects)

2026-02-03T18:29:26 < c10ud> ah, it's my 3.3V that's shit
2026-02-03T18:41:01 < zyp> yeah, that's not correct
2026-02-03T18:41:27 < zyp> it should be 1.5k pullup vs a 15k pulldown in the other end, 
2026-02-03T18:41:45 < c10ud> yes, and I think i somehow fucked the vcc because on the other board it was 3.3, inserted the cable and it became 2.something
2026-02-03T18:41:50 < c10ud> rebooting does not help
2026-02-03T18:41:53 < c10ud> weird
2026-02-03T18:42:51 < c10ud> i have a usb-c receptacle with 5.1k from CCx to gnd, d+ and d- go directly to the mcu via 22ohms, vbus floating
2026-02-03T18:43:04 < c10ud> either the footprint is fucked or idk
2026-02-03T18:43:30 < c10ud> i read somewhere the pullup was supposed to be inside the ip 
2026-02-03T19:02:49 < zyp> on f7, pullup is internal, yes

2026-02-04T11:20:59 < mawk> we have to use selenium bullshit to automate our own internal website because the php guys are too lazy to make us an API
2026-02-04T11:30:34 < ventyl> isn't backend an API on its own?
2026-02-04T11:36:06 < mawk> idk if they actually have a proper API, there's surely something to have the website frontend and backend communicate but it's not made to be used manually, and it requires the CSRF token generated when you login on the web interface 
2026-02-04T11:36:18 < mawk> and you can only login with microsoft SSO

2026-02-04T14:05:17 < mawk> but not interrupt mode at the same time as you need AF EVENTOUT, but I can probably use the RTC tamper interrupt for that

2026-02-04T21:39:06 < karlp> I bet this is because I cahnged to use gzip so that moduels install only took 5 minutes instead of 15 minutes, but now the kmod on the rpi doesn't know how to decompress them

2026-02-05T00:37:31 < karlp> if I have rights to insmod....
2026-02-05T00:37:51 < karlp> alright, fucking enough for tonight.
2026-02-05T00:38:00 < karlp> this driver is so wildly incomplete the more I look at it.
2026-02-05T00:38:27 < karlp> it's painfully apparent that it was merged because it came from a "correct" @ti.com email address, without even the slightest verification.
2026-02-05T00:38:41 < karlp> I know frrom experience that I would never have stood a chance of merging such incomplete trash.
2026-02-05T00:39:50 < karlp> I mean, he didn't even spell his email properly 
2026-02-05T00:42:11 < qyx> karlp: allow_other, fuse cares
2026-02-05T00:42:29 < qyx> also possibly allow_root
2026-02-05T00:42:52 < qyx> it is known nobody can access fuse mounts except the owner
2026-02-05T00:42:57 < qyx> including root
2026-02-05T00:44:59 < karlp> lol, it's fufcking not known
2026-02-05T00:45:06 < karlp> this is in the "har har fucking noob"
2026-02-05T00:45:27 < karlp> what's the fucking point in sudo?!
2026-02-05T00:45:39 < karlp> right, that's fucking it.
2026-02-05T00:45:44 < Phantom> sudo bash
2026-02-05T00:46:09 < Phantom> yet, in many distro, you can't "su"
2026-02-05T00:47:42 < qyx> karlp: no worries, you are welcome :>
2026-02-05T00:50:00 < karlp> Phantom: no, you're missing it.
2026-02-05T00:50:05 < karlp> sudo doesn't work on fuse
2026-02-05T00:50:08 < karlp> just... because...
2026-02-05T00:50:32 < karlp> turning this monitor off, don't want to fucking see any more of this shit today
2026-02-05T00:51:04 < qyx> are you back home?

2026-02-05T12:48:50 < qyx> -m
2026-02-05T12:49:07 < qyx> and parametrically they are very similar
2026-02-05T12:51:27 < zyp> speaking of nb-iot, the new ntn stuff is pretty amazing, I don't get how it's possible

2026-02-05T12:59:34 < qyx> to a geostationary?
2026-02-05T12:59:38 < zyp> yes
2026-02-05T13:00:05 < qyx> how much $$?
2026-02-05T13:01:00 < zyp> depends on the operator, tested one charges $.3/kB

2026-02-05T13:21:41 < karlp> which is, by claims, explicitly not qualcomm like the stm67w is.
2026-02-05T13:55:31 < karlp> is this normal for epaper fonts? https://bin.jvnv.net/file/LY4uc.jpeg it looks like trash, is that a bug in the epaper driver this person's using or something?

2026-02-05T15:01:10 < mawk> yeah it looks misconfigured
2026-02-05T15:01:39 < mawk> even cheap e-paper should have a couple bits to control the grey scale
2026-02-05T15:01:43 < mawk> and do some anti-aliasing
2026-02-05T15:02:16 < karlp> it's the it doesn't look like aliasing though, it looks like... I dunno, just.. wrong.
2026-02-05T15:04:20 < mawk> I got a couple samples of car key immobilizer transponders, I should be able to use them to open my office RFID lock
2026-02-05T15:04:23 < mawk> they're extra tiny
2026-02-05T15:04:34 < mawk> https://imgur.com/a/4ekbKUj
2026-02-05T15:04:59 < mawk> I will hide one inside a 3D-printed miniature model of the device we make to use as the key
2026-02-05T15:05:09 < karlp> those are super old, 
2026-02-05T15:05:20 < karlp> I rememember someone at uni doign indoor positioning using those
2026-02-05T15:05:22 < mawk> it's super tiny but it still has a better antenna than the genuine paxton tags, it's insane
2026-02-05T15:05:51 < mawk> ah nice
2026-02-05T15:06:13 < karlp> we made spare keys for a friends old car by pulling that out of the broken smart key, sticky taping it to the steering column and then just getting dumb "just cut the key part" keys cut
2026-02-05T15:06:24 < karlp> let him have two keys on the cheap.
2026-02-05T15:08:09 < mawk> nice
2026-02-05T15:11:11 < ventyl> there's a serial bus between ECUs in my car. previously, I've been able to find pinout diagrams which shown which pins carry it, now I can't find any.
2026-02-05T15:11:21 < mawk> you can clone them with relatively low effort, assuming it's the same model (PCF7936): http://www.proxmark.org/files/Documents/125%20kHz%20-%20Hitag/Gone_in_360_Seconds_Hijacking_with_Hitag2-USENIX_2012.pdf
2026-02-05T15:11:29 < mawk> you mean besides CAN ventyl ?
2026-02-05T15:11:45 < ventyl> my car predates existence of CAN by some ~1 year
2026-02-05T15:11:52 < mawk> maybe a proto version of it
2026-02-05T15:12:00 < ventyl> technically by around ~10
2026-02-05T15:12:12 < mawk> my car has no serial bus at all
2026-02-05T15:12:20 < mawk> or nothing else really
2026-02-05T15:12:27 < ventyl> its more probable that it will be K-line based
2026-02-05T15:12:46 < ventyl> probably a weird hybrid using K-line physical layer and CAN-line signalling
2026-02-05T15:13:39 < ventyl> its really just an internal bus between two parts of motor-management as this is realized as two independent controllers
2026-02-05T15:34:08 < Steffanx> Mawk: You mean you own a "benenwagen"?

2026-02-06T13:55:36 < mawk> for my custom nrf52 board I had to endure device tree torture and patching the zephyr drivers to be able to update the wifi module

2026-02-06T15:12:20 < qyx> Steffanx: I have the same experience as mawk
2026-02-06T15:12:27 < qyx> tried to use it on my hardware
2026-02-06T15:20:26 < Steffanx> Wasn't that hard either. 
2026-02-06T15:20:58 < Steffanx> If you want things existing drivers can't do, then yeah..
2026-02-06T15:22:28 < mawk> it was a case of the driver doing too much
2026-02-06T15:22:38 < mawk> and the low-level and high-level driver functions being intertwined
2026-02-06T15:23:19 < Steffanx> Oh this was your weird as old winc thingy?
2026-02-06T15:23:24 < Steffanx> *ass
2026-02-06T15:24:24 < Steffanx> But anyway, your experience is not my experience qyx 
2026-02-06T15:25:30 < mawk> yes
2026-02-06T15:34:15 < qyx> my experience is genuine and nonrepeatable
2026-02-06T15:35:56 < Steffanx> Yes. Absolutely 💯
2026-02-06T15:38:43 < qyx> and my current one is being cold or having some sort of flu
2026-02-06T15:41:46 < Steffanx> Lol again? 
2026-02-06T15:41:53 < Steffanx> > kids
2026-02-06T16:04:58 < karlp> kids have been pretty rough all week, wife's ben sick for a few days, I got a runny nose last night, and am good again today :)
2026-02-06T16:05:19 < karlp> biking through the winter makes me too touch for such trivialities as "colds" ands "coughs"
2026-02-06T16:09:46 < karlp> I love finding things like this: https://paste.jvnv.net/view/7Am1r
2026-02-06T16:09:49 < karlp> fills me with confidence.
2026-02-06T16:26:27 < c10ud> even the user code is full of confidence if null ptr check needs to be baked in

2026-02-06T18:00:49 < mrec_> did anyone play around with the stm32h7 and use HSE? I have two of those boards here, and desoldered one 25mhz crystal from the ethernet IC and added it to the STM32H7 however if I enable HSE my application doesn't work; I still have quite some room for investigation here but I wonder if there's something fundamental that has to be taken care about that I'm missing at the moment.
2026-02-06T18:04:11 < mrec_> I do see the 25mhz at the oscillator pins.
2026-02-06T18:06:04 < karlp> does h7 work with 25M ext?
2026-02-06T18:06:11 < karlp> some of them only go to 24 or something..
2026-02-06T18:07:01 < mrec_> HSE on-board oscillator from X3 crystal (not provided): For its typical frequencies,
2026-02-06T18:07:04 < mrec_> capacitors, and resistors, refer to the STM32H7 series microcontroller datasheet and
2026-02-06T18:07:07 < mrec_> the application note Oscillator design guide for STM8AF/AL/S and STM32
2026-02-06T18:07:09 < mrec_> microcontrollers (AN2867) for the oscillator design guide. The X3 crystal has the
2026-02-06T18:07:12 < mrec_> following characteristics: 25 MHz, 6 pF, 20 ppm. The configuration must be:
2026-02-06T18:07:36 < mrec_> according to the bom they suggest the same crystal as they use for the ethernet chipset (so I desoldered it from the second board)
2026-02-06T18:08:23 < mrec_> the 25mhz signal is there I'm just not sure what the stm32 is doing with it :-)
2026-02-06T18:26:55 < qyx> karlp: oh o/\o
2026-02-06T18:27:27 < qyx> wait one more day, I was good yesterday after having running nose 2 days ago, thats the start
2026-02-06T18:27:45 < qyx> other things being equal
2026-02-06T18:31:24 < catphish> today's STM32 fun: i have a DAC and an ADC triggered by the same timer. i noticed today the ADC was sampling at half the speed of the DAC. took me quite a while to figure out that the ADC clock was too slow for it to keep up with requests from the timer, so it was skipping every 2nd sample
2026-02-06T18:45:25 < mawk> well it depends what you configured for the sampling time
2026-02-06T18:45:36 < mawk> the adc will happily sample too fast if you tell it to
2026-02-06T18:45:45 < mawk> then you get garbage data but it doesn't complain
2026-02-06T18:46:13 < catphish> that's not what mine did. it just skipped every 2nd request
2026-02-06T18:46:36 < mawk> even though the sampling time + conversion time was less than the clock period?
2026-02-06T18:47:15 < catphish> no, to be clear, the sampling time + conversion time was longer than the period at which the timer was triggering it
2026-02-06T18:47:22 < mawk> ah, then yeah of course
2026-02-06T18:48:14 < mawk> if you keep it under like 1Msps it should always be fine no matter the configuration, if you go faster you have to start looking at the signal source impedance and the analog path for that ADC channel, or decrease the resolution
2026-02-06T18:50:12 < catphish> i was previously running the STM32 at 240MHz, and i had a timer with a 2400 divider that triggered the ADC at 100ksps, it worked fine. i then lowered the peripheral clocks to 64MHz to save power, and changed the divider to 640, so the timer still triggered the ADC at 100ksps, but now with the slower clock, the sampling time exceeded 10us
2026-02-06T18:50:51 < qyx> thats an expected outcome
2026-02-06T18:51:10 < qyx> there was even a figure showing what happens when a trigger comes when a conversion is ongoing
2026-02-06T18:51:19 < catphish> anyway, changing the clock divider on the ADC from /8 to /4 was enough to speed it up sufficiently to sample in time
2026-02-06T18:51:49 < catphish> that makes sense, it puzzled me for a little too long, but does seem like an obviously correct behaviour

2026-02-06T23:14:50 < mawk> I ran out of cards to abuse 
2026-02-06T23:14:52 < mawk> and tags
2026-02-06T23:14:55 < mawk> need to get new ones
2026-02-06T23:15:07 < mawk> or maybe try to read the dutch passport now
2026-02-06T23:15:23 < mawk> open source eMRTD tools fail to read it, it has special encryption or something 
2026-02-06T23:16:17 < mawk> I was able to not only read but write to my Dijon bus pass, they have no password and no write protection, I'm pretty sure I could roll back the card to an earlier state after using it and get infinite travel
2026-02-06T23:16:36 < mawk> I wrote some obscenities in the memory in the meantime 
2026-02-06T23:17:07 < mawk> there are 8 bytes that are down-counting only that might be used for security if they were smart
2026-02-06T23:25:56 < qyx> mawk: they are checking that
2026-02-06T23:26:04 < qyx> at least here they are
2026-02-06T23:26:19 < qyx> buses are refueled with data at end stops
2026-02-06T23:26:35 < mawk> but what happens with the down counters
2026-02-06T23:26:55 < mawk> in dutchland all the data is on the card itself 
2026-02-06T23:27:12 < mawk> if you change the credit then the card uploads its new data to the server when you go to the station 
2026-02-06T23:27:15 < qyx> yes here too
2026-02-06T23:27:17 < mawk> not the other way around 
2026-02-06T23:27:31 < qyx> but data exchange with he web and the whole infrastructure hapoens at end stops
2026-02-06T23:27:58 < qyx> when you buy a new ticket inoine, it gets written to bus db at the end stop and then gets written to your card
2026-02-06T23:28:05 < mawk> right
2026-02-06T23:28:20 < qyx> theh tell you explicitly when your ticket becomes valid
2026-02-06T23:28:32 < mawk> in dutchland if you manually change the card credit it also updates the fake value on the server
2026-02-06T23:28:36 < qyx> so I guess they are checking that in the other direction too
2026-02-06T23:28:46 < qyx> there was a large fuckup right at the beginnih
2026-02-06T23:28:52 < qyx> so they probably fixed that
2026-02-06T23:28:53 < mawk> but they run regular discrepancy checks and ban you if it's bad, but it takes a while for the checks to run, maybe weekly
2026-02-06T23:29:27 < qyx> also you can here with a credit card
2026-02-06T23:29:40 < mawk> in paris the card is the only source of data, but it's some kind of secure smartcard crap
2026-02-06T23:29:43 < qyx> but if there is not enough money, your card gets banned on the second day
2026-02-06T23:29:45 < mawk> probably with public key signing 
2026-02-06T23:29:55 < mawk> yeah in NL too
2026-02-06T23:30:09 < mawk> so people used to make virtual cards with revolut or n26 and travel for free
2026-02-06T23:30:13 < mawk> so now they banned these banks 
2026-02-06T23:31:11 < mawk> the dijon card is some obscure ST bullshit you can't even buy online except in bulk by packs of 1000, I doubt they had security in mind
2026-02-06T23:33:18 < mawk> I'm sure there was corruption by ST officials to get them to choose this instead of something a bit more secure like mifare ultralight with AES
2026-02-06T23:33:48 < mawk> ikea rothult lock cards at least have a password, they're some weird ST tags too
2026-02-06T23:33:55 < mawk> but the password is transmitted in cleartext
2026-02-06T23:34:05 < qyx> what, legit2?
2026-02-06T23:34:18 < qyx> whats the correct name
2026-02-06T23:35:00 < qyx> oh legic2
2026-02-06T23:35:01 < mawk> in dijon it's ST SRT512 and ikea is ST25TA
2026-02-06T23:35:32 < qyx> also fucking H8N17 bird flu or what abomination is this
2026-02-06T23:35:39 < mawk> lol
2026-02-06T23:35:45 < qyx> I am going to disassemble till the morning

2026-02-08T21:09:46 < Steffanx> Ever considered sueing your employer jpa- ?
2026-02-08T21:20:00 < catphish> Is anyone familiat with the LTDC peripheral? I've been helping someone debug a problem but i'm totally out of ideas. The LTDC is reading pixels from DRAM and sending them to a display via DSI. Sometimes, the image will get offset to the right by a few pixels, as if the DRAM reads are falling beind the image output. However it doesn't seem to trigger the underrun flag, nor can I figure out why.
2026-02-08T21:20:56 < jpa-> is the offset temporary or persisting?
2026-02-08T21:21:10 < jpa-> also which stm32? h7?

2026-02-08T22:08:30 < catphish> jpa-: once it happens, it persists, the image remains offset, always to the right, and sometimes it will then happen again and offset further, it continues to work otherwise, but the visible pixels remain offset from the sync signals. it's a STM32F469
2026-02-08T22:11:45 < catphish> it's like there's 2 parts to the peripheral, one that generates visible pixes, and one that packs them into lines, and no synchronization between the two except at the initial reset, so if the part that generates pixels falls behind, the whole image is just offset forever
2026-02-08T22:12:44 < mawk> it's DMA right?
2026-02-08T22:13:05 < mawk> is the buffer aligned properly? are you using the FIFO?
2026-02-08T22:13:13 < mawk> there are extra alignment requirements with the FIFO
2026-02-08T22:13:22 < mawk> at least on H7, idk about that of F4
2026-02-08T22:16:51 < catphish> i'd think if there was an alignment problem it would just be persistently broken, but i'll check
2026-02-08T22:17:22 < catphish> i'm not sure how the DMA part works, i'll try to find more details, this one isn't my project, just helping someone

2026-02-09T12:13:31 < jpa-> catphish: hmm, that's a reasonable explanation too
2026-02-09T12:14:04 < jpa-> though the LTDC fifo underrun flag not getting set is weird in either case
2026-02-09T12:15:42 < jpa-> if it was just once, it could be some software bug messing up LTDC registers, but that's unlikely to result in a second shift in same direction
2026-02-09T12:17:09 < jpa-> and i assume there are writes to the framebuffer too, so it cannot be the SDRAM interface being in eternal "read next row" mode
2026-02-09T12:17:25 < jpa-> (oh well, it'd have to return to start anyway)
2026-02-09T12:18:06 < jpa-> i wonder if DSI burst mode vs. non-burst mode makes any difference

2026-02-09T18:35:35 -!- ou5x is now known as oz4ga
2026-02-09T18:38:36 < jpa-> what kind of data? big, small, packets, stream, how frequently?
2026-02-09T18:39:10 < mrec_> domain sockets, they are probably the safest
2026-02-09T18:39:44 < qyx> the data is always serialized and packetized in, let's assume, <64KB packets
2026-02-09T18:39:47 < mrec_> android doesn't have shared memory enabled, they have their own implementation
2026-02-09T18:40:02 < mrec_> small packets, domain sockets / udp
2026-02-09T18:40:06 < jpa-> sockets will be kinda annoying to manage in n:m
2026-02-09T18:40:26 < qyx> the processes are arranged in a "data flow graph"
2026-02-09T18:40:43 < qyx> one output can go into multiple inputs
2026-02-09T18:40:59 < qyx> but inpit can be connected to one output only
2026-02-09T18:41:13 < jpa-> https://lkml.org/lkml/2012/2/20/208   apparently linux domain sockets have multicast
2026-02-09T18:42:22 < qyx> oh maybe I could actually use dbus
2026-02-09T18:45:07 < jpa-> or maybe it doesn't have multicast, that patchset doesn't seem to be merged in
2026-02-09T18:47:20 -!- hexo_ is now known as hexo
2026-02-09T18:47:25 < qyx> and then there is zmq..
2026-02-09T18:47:29 < mrec_> udp multicast :-)
2026-02-09T18:48:29 < mrec_> so many ways.
2026-02-09T18:48:48 < jpa-> udp multicast with 64kB packets sounds like "if you want to receive only part of your data, and in pieces" ;)
2026-02-09T18:52:24 < qyx> one of the people at my company is concerned because the main person behind ZMQ has died, and apparently not much has been happening with ZMQ since.
2026-02-09T18:52:27 < qyx> wat
2026-02-09T18:55:16 < jbo> best to rewrite everything in rust anyway
2026-02-09T19:09:40 -!- rkta_ is now known as rkta
2026-02-09T19:21:33 < qyx> oh there is a native rust implementation too, fairly active
2026-02-09T19:23:00 < Steffanx> Zmq guy died almost a decade ago, why this guy in concerned now qyx?
2026-02-09T19:28:36 < nohit> karlp: i commented on 2 separate things
2026-02-09T19:30:05 < nohit> 1) why use headless cubeide when there is cubeclt 2) cubemx has always been around as a standalone
2026-02-09T19:30:21 < nohit> i did not claim they are the same thing
2026-02-09T19:35:17 < jpa-> qyx: for new and fancy, there is apparently nng
2026-02-09T19:48:58 < qyx> Steffanx: I didn't even notice

2026-02-09T20:37:59 < catphish> jpa-: DSI burst mode makes no difference either way
2026-02-09T20:38:14 < catphish> (i tested that early on)
2026-02-09T20:40:15 < jpa-> you could write some code that loads the SDRAM interface a lot, and see if the problem occurs more frequently
2026-02-09T20:40:50 < jpa-> LTDC->ISR is a bit weird in that it doesn't say when the fifo underrun flag gets cleared
2026-02-09T20:41:04 < jpa-> presumably only in ICR write
2026-02-09T20:41:20 < jpa-> but some peripherals clear flags on end of condition
2026-02-09T20:42:36 < catphish> jpa-: yeah, it's a bit anecdotal but i'm told it gets better (ie less frequent but not fixed) at lower pixel rates, and gets worse (more likey to occur) when RAM is being written to
2026-02-09T20:43:33 < jpa-> some kind of problem in the SDRAM bus or timing parameters would be an easy explanation, but i can't see how that would produce a permanent shift without causing a FIFO underrun
2026-02-09T20:44:11 < catphish> i'm told the underrun was tested with an interrupt and it was ONLY fired when the clock speed was set so high that the ram couldn't keep up, not when the problem occurs
2026-02-09T20:45:08 < catphish> i haven't looked at it again yet, but sure seems like the DMA and FIFO is where to look
2026-02-09T20:45:36 < catphish> we already triple checked the RAM settings in general and tried running it more conservatively
2026-02-09T20:45:55 < jpa-> is LTDC using same or different clock freq than AHB? maybe it is some kind of clock domain crossing bug that ST just hasn't put in errata
2026-02-09T20:46:43 < catphish> good question, i'll have to check, probably different divisions ot the PLL
2026-02-09T20:47:02 < jpa-> oh, and check that all clocks are within their maximum limits

2026-02-10T01:37:56 < nomorekaki> I think it has been like a year or two when I last touched the project
2026-02-10T01:39:25 < nomorekaki> so long that debian has changed version
2026-02-10T01:39:39 < Phantom> it's a project I worked on, then was put on standby, but then I started to work on it just the day I got hurt...
2026-02-10T01:39:50 < nomorekaki> damn
2026-02-10T01:39:57 < nomorekaki> what is it?
2026-02-10T01:40:14 < Phantom> a simple motor controller, so fortunately nothing complicated
2026-02-10T01:40:41 < Phantom> I'm moving it from a F103 to a G431, and doubling the drivers so it drives 2 motors intead of 1
2026-02-10T01:41:30 < nomorekaki> doesn't sound complicated if you have done the single driver code in right way
2026-02-10T01:41:39 -!- jfsimon [~jfsimon19@2a01:cb14:b9b:2000:152a:64f6:40a4:5cac] has quit [Remote host closed the connection]
2026-02-10T01:41:51 < Phantom> the code needs to be 100% rewritten
2026-02-10T01:43:44 < nomorekaki> damn
2026-02-10T01:46:01 < nomorekaki> to be fair my code also doesn't support multiple instances
2026-02-10T01:46:45 < nomorekaki> because it's all size and performance optimized to run on 8bit
2026-02-10T01:47:02 < nomorekaki> run on anything that has one single timer available
2026-02-10T01:47:08 < Phantom> my code for that one was a proof of concept
2026-02-10T01:48:13 < nomorekaki> lets see if I can break debian with apt
2026-02-10T01:48:23 < ventyl> that should be trivial

2026-02-10T02:02:12 < Phantom> so, on a thursday I couln't go to work because I got hit by covid and it knocked me off... by monday the symptoms were gone, but too tired to work. Tuesday I went to work half tired...  thursday that same week the stone hit...

2026-02-10T02:05:11 < Phantom> so for me, it started like wednesday the 7 in january (covid), then stone, and still going... 2 operations so far (they installed a JJ stent, then removed to burst the stone... they couln't find it, so reinstalled a new stent), friday the 13 they will remove the stent... and somewhere in 2-4 weeks they will do another scan to see if the stone is really gone
2026-02-10T02:06:43 < qyx> TIL JJ stent
2026-02-10T02:08:04 < Phantom> "fun" fact, each time you take a piss, you get hurt by it as the differential in pressure cause it to hit inside your kidney. It's like someone pinch you from the inside, each single time... 
2026-02-10T02:08:32 < nomorekaki> do you know that you have kidney stones?
2026-02-10T02:08:50 < Phantom> a scan said I do
2026-02-10T02:08:51 < nomorekaki> before it's a problem
2026-02-10T02:08:55 < Phantom> but no
2026-02-10T02:10:13 < Phantom> that thursday at about 10am... I was at my desk working on some schematics... and "someone" squizzed my kidney... and the pain didn't went away.. so had to drive home... on my 25 minutes drive home, I strongly considered to stop and call an ambulance
2026-02-10T02:10:49 < Phantom> it didn't helped that it was snowing, and idiots that shouln't be on the road seems to all decided to go out...
2026-02-10T02:11:25 < Phantom> the road was fine, why the heck are they driving at 30-35km/h when you can do 60 no issue? 
2026-02-10T02:12:04 < Phantom> Left lane was doing 60-65, but always stopped due to left turns...   right lane, which is where I had to be anyway to turn... right soon... was doing 25-35...
2026-02-10T02:12:57 < Phantom> the police said that about 1/5 cars don't have winter tires... so that is probably why... they really need to do some extra checkup and fine those idiots
2026-02-10T02:13:38 < nomorekaki> is it illegal to drive on summer tyres?
2026-02-10T02:14:05 < Phantom> in winter, yup, 4 seasons ain't allowed unless it have the flake symbol, which most don't
2026-02-10T02:14:11 < Phantom> so they are 3 seasons
2026-02-10T02:14:20 < qyx> wouldn't it be considered a restriction to their freedom?
2026-02-10T02:14:22 < nomorekaki> so it's not enforced

2026-02-10T02:14:35 < Phantom> it is enforced, but only if you get caugh
2026-02-10T02:14:42 < qyx> yeah same here
2026-02-10T02:14:45 < Phantom> qyx: nope, it's a safety issue

2026-02-10T02:15:02 < Phantom> .qc.ca
2026-02-10T02:15:27 < qyx> i wohldn't even consider avoiding winter tire change there
2026-02-10T02:15:53 < qyx> even here at 17-18° we regularly change to winter tires in Oct/Nov
2026-02-10T02:15:55 < nomorekaki> I don't know if I could get anywhere on summer tyres
2026-02-10T02:15:55 < Phantom> you would, because winter tires melt in summer
2026-02-10T02:16:14 < qyx> I wouldn't consider avoiding :)
2026-02-10T02:16:39 < nomorekaki> I tried once because my car was on summer tyres when it broke down and then winter came
2026-02-10T02:16:45 < Phantom> so I have 2 sets of rubber donuts, mounted on 2 sets of rims, alloy for summer, steel for winter
2026-02-10T02:16:56 < qyx> same here
2026-02-10T02:16:58 < Phantom> each with TPMS
2026-02-10T02:17:09 < qyx> quite common in middle/north eu I think
2026-02-10T02:18:51 < Phantom> and I can tell that when I install my Michelin X-Ice that it have a major increase in traction compared to my Pirelli whatever I have for summer
2026-02-10T02:19:36 < Phantom> and in spring, whne I install the summer ones, again increase in traction, because now the winter get too soft and just kinda slip
2026-02-10T02:28:18 < qyx> it is kinda hard to accuratelly predict the exact date to change here so driving on the wrong set is unavoidable sometimes
2026-02-10T02:28:55 < qyx> where I currently live, the temperature usually never falls below 10°C during the whole October
2026-02-10T02:29:15 < qyx> but I am driving through areas where it can already freeze at that time
2026-02-10T02:30:25 < qyx> and while I may avoid changing until late November, in that case I must also avoid driving some locations in the morning/evening/night
2026-02-10T02:30:38 < qyx> *delay, not avoid

2026-02-10T11:16:47 < mawk> does wolfssl/libcurl support bare metal without RTOS?
2026-02-10T11:18:00 < jpa-> i don't see why RTOS would make a difference to it
2026-02-10T11:18:49 < jpa-> malloc might be necessary, and it could end up taking a lot of code space
2026-02-10T11:19:41 < ventyl> wolf* things usually don't allocate memory
2026-02-10T11:19:54 < jpa-> https://www.wolfssl.com/tiny-curl/   this is probably better than normal libcurl
2026-02-10T11:21:22 -!- SystemError [~SystemErr@user/systemerror] has joined ##stm32
2026-02-10T11:21:33 < jpa-> apparently most of that is upstreamed
2026-02-10T11:24:32 < jpa-> the "freertos" part of tiny-curl is apparently just a bunch of defines to functions like FreeRTOS_send() etc.
2026-02-10T11:24:41 < jpa-> it does not appear to use tasks
2026-02-10T11:25:49 < jpa-> and there appear to be direct lwip bindings too
2026-02-10T11:34:57 < qyx> I was using wolfcrypt and wolfmqtt, both were fine
2026-02-10T11:35:05 < qyx> and wolfssl of course, around 2015
2026-02-10T11:35:42 < qyx> when chacha20/poly1305 wasn't widespread yet, they had a working implementation
2026-02-10T11:37:06 < qyx> wolfmqtt was mostly rtos-agnostic and I did a socket layer to operate using quectel's gprs modem tcp/ip stack
2026-02-10T11:37:52 < qyx> as with other embedded crypto stuff, beware of insane stack space required
2026-02-10T11:43:17 < jpa-> i don't get why crypto stuff is so heavy, can't they just use rot13/caesar or something?

2026-02-10T11:44:22 < qyx> they could at least use preallocated context buffers for memory heavy operations
2026-02-10T11:44:43 < qyx> because stack is kinda hard to share between threads without adverse effects :>
2026-02-10T11:45:22 < qyx> (yeah zyp coming with the coroutine stuff)
2026-02-10T11:45:40 < jpa-> (and someone else coming with rpc stuff and delegating crypto to one thread)
2026-02-10T11:45:41 < zyp> hmm?
2026-02-10T11:46:06 < qyx> haha
2026-02-10T11:47:44 < qyx> reminds me of that discussion to "lock the radio, but not too hard to allow unlocking, but not anytime"
2026-02-10T11:47:58 < qyx> s/to/about
2026-02-10T11:49:09 < qyx> something like "allocate 30KB but wait for it 100 ms if not immediately available"
2026-02-10T11:49:15 < ventyl> well, I actually plan to integrate wolf* stuff using RPC
2026-02-10T11:50:07 < zyp> qyx, stack isn't that hard to share, as long as you don't have to return while it's shared
2026-02-10T11:50:42 < zyp> allocate a buffer, pass a handle to whatever other thread will fill or consume it, block until it's done
2026-02-10T11:52:36 < ventyl> you have basically described what RPC does. with one small difference - other thread is the same as calling thread
2026-02-10T11:53:58 < zyp> my zephyr mqtt stuff does this
2026-02-10T11:54:01 < qyx> zyp: the other way around, crypto stuff requires stack to be deep

2026-02-10T11:54:30 < zyp> yeah?
2026-02-10T11:54:44 < zyp> so just call crypto stuff on a dedicated thread
2026-02-10T11:54:58 < qyx> yes and thats stupid
2026-02-10T11:55:09 < qyx> because it is wrog
2026-02-10T11:55:19 < qyx> from the security standpoint
2026-02-10T11:55:33 < qyx> also it is an unneccessary complication
2026-02-10T11:56:26 < zyp> you could use a workqueue thread to call crypto stuff and just ensure the workqueue thread has enough stack
2026-02-10T11:56:50 < qyx> of course but still stupid
2026-02-10T11:57:14 < qyx> you are delegating your key material to someone else
2026-02-10T11:57:47 < ventyl> that's stupid argument given the fact an average embedded developer hates essential memory isolation, so someone else actually == me
2026-02-10T11:58:03 < zyp> :p
2026-02-10T11:58:49 < ventyl> at FOSDEM I trolled ArielOS developers
2026-02-10T11:59:27 < ventyl> again, they first designed the OS and then they wanted to add isolation and found out it is not possible without breaking the API
2026-02-10T11:59:30 < ventyl> so they gave up
2026-02-10T11:59:35 < qyx> you should allocate a temporary working buffer from a secure memory, perform your stuff, free the buffer (which clears it in a secure manner before allowing to be allocated by someone else)
2026-02-10T12:00:09 < ventyl> and the excuse is: MPU is hard
2026-02-10T12:39:07 < qyx> isnt it
2026-02-10T12:50:19 < ventyl> is it?

2026-02-10T17:11:44 < mercenary> add to self, a.k.a. * (20/10). you have to help the compiler a bit to make it do full constant folding https://godbolt.org/z/rn7PK7a7P
2026-02-10T17:19:26 < karlp> that' sso weird.
2026-02-10T17:24:32 < mercenary> remove all brackets, and it will happily generate 3 fmuls and an fdiv, even with -O2
2026-02-10T17:24:44 < flatmush> it's float so the ordering matters and gives different results
2026-02-10T17:24:58 < qyx> better use the Claude C compiler, or what abomination ventyl mentioned recently
2026-02-10T17:25:03 < qyx> it will no longer be a problem
2026-02-10T17:25:43 < flatmush> which is why you should repent and use fixed point returning millivolts
2026-02-10T17:27:45 < karlp> fuck that, I've got this fpu right here :)
2026-02-10T17:30:28 < karlp> fixed point is way too easy to end up with it returning 0 :)
2026-02-10T17:32:19 < karlp> like, leave the brackets in? bamn, zero
2026-02-10T17:32:34 < flatmush> skill issue :p
2026-02-10T17:33:00 < karlp> I never claimed to be competent :)
2026-02-10T17:33:23 < karlp> but it's a big gun to get truncation when you didn't want it...
2026-02-10T17:33:42 < flatmush> the bigger issue for me is when intermediates span more than 32-bits, but that's because I like to avoid calls to libgcc
2026-02-10T17:33:42 < flatmush> I'd still take that over floating point issues though
2026-02-10T17:34:04 < karlp> what floating point issues?
2026-02-10T17:34:10 < karlp> forgetting to use f suffices and getting doubles?
2026-02-10T17:34:43 < karlp> I absolutely cannot care less about the 10th decimal place being different because I did things in the "wrong" order but I got a float that is otherwise correct.
2026-02-10T17:35:01 < karlp> naiively doign integer manths and having it all become zero because some ratio was less than 1? gtfo.
2026-02-10T17:35:28 < karlp> pre-calculating the integer factors because it can't be constnat folded anuymore? gtfo
2026-02-10T17:37:56 < flatmush> what fun would floating point issues be if you could predict them in advance?
2026-02-10T17:40:56 < karlp> float: 39 cycles, mv fixed 26 cycles...
2026-02-10T17:41:23 < karlp> now, I'm doing this.... about 2hz, so..... I think I'd better take the high performance path....
2026-02-10T17:42:32 < flatmush> float can be faster if you do -ffast-math
2026-02-10T17:43:39 < karlp> no wonder you have flaoting poitn problems :)
2026-02-10T17:43:57 < karlp> -fplease-make-my-floats-weird
2026-02-10T17:43:59 < mercenary> bonus points for doing the calculation in float, then returning (int)v*1000 // in mV
2026-02-10T17:44:06 < flatmush> floats come weird
2026-02-10T17:44:21 < karlp> mercenary: at least you won't get caught by the surprises with truncation if you do that...

2026-02-10T17:46:52 < karlp> fuck offf
2026-02-10T17:48:01 < jpa-> i tend to mess up with overflows more than ttuncation
2026-02-10T17:52:32 < flatmush> for ints just multiply first and ensure that the multiplied maximum value doesn't exceed the integer range, not that hard
2026-02-10T17:52:32 < flatmush> the float thing becomes: return ((uint32_t)adc * 3300 * 2) / 4095;
2026-02-10T17:52:32 < flatmush> seems fairly straightforward to me, and doesn't invoke complex circuitry
2026-02-10T17:54:16 < karlp> I'm with jpa, surprise overflow will fuck you easily too.

2026-02-10T17:55:56 < jpa-> but you are already throwing away resolution there
2026-02-10T17:56:33 < karlp> flaots are hard apparently, don't want resolution ;)
2026-02-10T17:56:38 < jpa-> but yeah, i would fixed point that too if there is no more float stuff folöowing
2026-02-10T18:00:26 < flatmush> I never said floats were hard, but you were confused yourself by what the compiler was doing earlier
2026-02-10T18:03:06 < karlp> only because I looked at the generated code :)
2026-02-10T18:03:12 < karlp> it "worked" just fine ;)
2026-02-10T18:03:55 < karlp> more concerned with why it reads low right now, 
2026-02-10T18:05:25 < flatmush> well you divide by 4096 instead of the correct 4095, so fixing that will get you 0.02% closer ;)
2026-02-10T18:06:01 < karlp> how can that be an error, no floats there ;)
2026-02-10T18:06:27 < karlp> looks like 3v3 is a touch high, and with the 11 multiplier it just adds up a lot.
2026-02-10T18:07:16 < flatmush> adc range is up to 4095 not 4096, so 4095 is 3.300v (if that's your vref)

2026-02-10T18:21:15 < ventyl> you'd probably have hard time linking bare metal executable with it
2026-02-10T18:21:40 < ventyl> anthropic states they were able to compile linux kernel with it but that's a partial lie
2026-02-10T18:21:52 < ventyl> as compilation passed but stuff crashed when linking

2026-02-11T01:29:36 < mawk> ISO14443A/NFC-A card found. UID: 930458A9
2026-02-11T01:29:43 < mawk> I used a different nucleo
2026-02-11T01:29:47 < mawk> I guess the other nucleo is broken
2026-02-11T01:30:48 < ventyl> told ya
2026-02-11T01:36:48 < mawk> maybe it was the solder bridge configuration
2026-02-11T01:36:48 < mawk> idkl
2026-02-11T01:36:54 < mawk> I didn't want to butcher it
2026-02-11T01:36:57 < mawk> it was my H7
2026-02-11T01:37:03 < mawk> so I butchered my L1 nucleo instead
2026-02-11T01:37:35 < mawk> I have the ST25R3916 reader
2026-02-11T01:37:37 < mawk> it's pretty powerful
2026-02-11T01:37:45 < mawk> it can find my card like 5-6cm away
2026-02-11T01:37:50 < mawk> better than my 400€ proxmark3
2026-02-11T01:38:02 < mawk> and it has a fully transparent mode to implement custom protocols
2026-02-11T01:38:41 < mawk> ST have even better readers like 2.5W implementing the NCI protocol
2026-02-11T01:38:52 < mawk> but these fuckers gated the transparent feature to implement mifare classic and all that behind a NDA
2026-02-11T01:38:57 < mawk> they start to sound like NXP
2026-02-11T01:39:41 < mawk> with the ST25R3916 I just have to know what the CRYPTO1 algorithm is and I can implement it, no NDA needed
2026-02-11T01:51:15  * h4x0riz3d has a reader with clrc66303 at $job
2026-02-11T01:52:10 < h4x0riz3d> it reads from more than 6cm even with my silly small-ish antenna and the passives straight out of NXP's antenna calculator, i haven't tuned sh*t
2026-02-11T01:52:40 < h4x0riz3d> hm, but TVDD==5V, i should try it on 3.3V
2026-02-11T01:58:13 < h4x0riz3d> https://i.imgur.com/8qrRlVd.png
2026-02-11T02:01:07 < zyp> mawk, https://bin.jvnv.net/file/Hv9jL.mp4
2026-02-11T02:01:52 < zyp> IIRC that's a ST95HF
2026-02-11T02:03:06 < zyp> mawk, also, let me know when you've got crypto1 working, I have some stuff I want to do with some mifare classic tags
2026-02-11T02:03:28 < h4x0riz3d> afaik the NXP "crapto1" is broken long long ago
2026-02-11T02:03:31 < qyx> I have 10 free desfire readers if anyone is interested
2026-02-11T02:03:50 < qyx> idk which ones, I can check
2026-02-11T02:04:05 < zyp> h4x0riz3d, yep, but it's a difference between it being possible in theory and having a practical implementation around a specific reader
2026-02-11T02:04:27 < qyx> this https://www.stronglink-rfid.com/en/rfid-modules/sl032.html
2026-02-11T02:04:51 < mawk> seems that 2 GPIOs are broken but they're just leds
2026-02-11T02:05:38 < mawk> you have the docs with them qyx ?
2026-02-11T02:05:40 < mawk> with the desfire protocol
2026-02-11T02:05:51 < zyp> mawk, I don't remember if ST95HF has the same transparent mode you're using, but if it is, I can give you a couple of those boards for you to implement mifare classic on
2026-02-11T02:05:55 < qyx> there are many docs on that page I pasted
2026-02-11T02:06:02 < qyx> it looks like some STM32
2026-02-11T02:06:04 < mawk> yeah it has zyp 
2026-02-11T02:06:08 < mawk> I just checked
2026-02-11T02:06:09 < zyp> I think I still have a few tens of those boards left
2026-02-11T02:06:43 < mawk> normally if I implement it on RFAL it should work on all readers
2026-02-11T02:06:56 < mawk> all mifare classic needs is the ability to disable auto-processing CRC and parity bits
2026-02-11T02:07:04 < mawk> that's the only deviation from ISO-14443-3
2026-02-11T02:07:27 < zyp> oh, fuck rfal :p
2026-02-11T02:07:33 < mawk> lol
2026-02-11T02:07:46 < mawk> it shouldn't be too hard to implement with raw SPI
2026-02-11T02:07:55 < mawk> but it's much more annoying for the initialization, with the anti-collision loop
2026-02-11T02:07:59 < mawk> if you do it properly that is
2026-02-11T02:10:25 < mawk> here page 29 https://www.st.com/resource/en/datasheet/st95hf.pdf
2026-02-11T02:10:46 < mawk> the parity framing mode and the append crc flags, that's all we need for MFC
2026-02-11T02:10:59 < mawk> and split frame for the anticollision frame
2026-02-11T02:11:10 < zyp> nice
2026-02-11T02:12:41 < zyp> hmm, my existing code is not very elaborate :p https://cgit.jvnv.net/cardio/tree/main.cpp#n523
2026-02-11T02:13:05 < mawk>  lol
2026-02-11T02:13:20 < zyp> original applications just cares about the card ID, and presents it as a text file on a mass storage device :p
2026-02-11T02:13:51 < mawk> yeah here too it just checks the UID
2026-02-11T02:14:04 < zyp> also, ignore that it says CR95HF, I prototyped with that before I made the boards with ST95HF
2026-02-11T02:14:13 < mawk> but for mifare classic it's just as secure as the card contents, both card cracking and UID cloning are trivial
2026-02-11T02:14:28 < mawk> there are variants of mifare classic that we can't crack yet, with a static encrypted nonce
2026-02-11T02:14:40 < mawk> well, we couldn't crack at least, if the manufacturer didn't let a backdoor key inside
2026-02-11T02:14:50 < mawk> https://eprint.iacr.org/2024/1275
2026-02-11T02:21:51 < qyx> who is "we"
2026-02-11T02:21:58 < qyx> why are you breaking stuff
2026-02-11T02:22:03 < qyx> thats illegal

2026-02-11T20:50:25 < zyp> almost tempted to dig out my ST25HF boards and give it a try
2026-02-11T20:53:22 < mawk> since you don't have RFAL the first thing you have to do is anti-collision
2026-02-11T20:53:26 < mawk> to have several tags in the field
2026-02-11T20:53:40 < mawk> you can do it quick and dirty and assume there will always be only one tag and error out in case of collision I guess
2026-02-11T20:53:54 < mawk> but with 5-7cm reading range the risk of collision is real

2026-02-11T20:58:29 < mawk> you send WUPA without CRC (0x52, sent with only 7 bits in a short frame) to wake the card up, the tag answers 04 00 without CRC, then you send 93 20 without CRC to get the card to spit its UID and check byte, then 93 70 + UID + CRC to select the tag, then the tag answers with its SAK (1 byte) + CRC, and now the tag is alive
2026-02-11T20:58:57 < mawk> of course this will fail with several tags in the field, then the ST25HF tells you when there is a collision, and you need to do a select of all UIDs up to the first collided bit, and then on and on until there are no more collisions
2026-02-11T20:59:29 < zyp> yeah, I know how anticollision works, just havent needed to bother with it
2026-02-11T21:01:31 < mawk> ah right
2026-02-11T21:01:50 < mawk> also yeah for 7 or 10 bytes UID what I said isn't enough
2026-02-11T21:03:13 < zyp> from my perspective, anticollision is mostly useful when you either know how to filter for the tag you're interested in, or have an actual reason to process multiple at once
2026-02-11T21:03:36 < zyp> libraries do the latter when they let you check out or in a whole stack of books in one operation
2026-02-11T21:04:08 < mawk> well you have to do it in any case even if there's just one tag, it's just that for 4 bytes UID with only 1 tag in the field there's not really a loop happening and it's all easy and simple
2026-02-11T21:04:30 < mawk> unless you know the UID in advance then you can select it directly
2026-02-11T21:04:41 < mawk> but otherwise the tags won't answer to commands if they're not selected

2026-02-11T21:05:03 < mawk> ah yeah
2026-02-11T21:05:15 < zyp> which both are just a single command to spit out the whole 8-byte UID

2026-02-11T21:45:09 < Steffanx> I never had that so far. Only Amazon uses some weird ass unknown shipper sometimes. 
2026-02-11T21:45:34 < Steffanx> maybe they only use their own it in the "big" cities of dutchland?
2026-02-11T21:59:44 < mawk> idk if it's their own actually 
2026-02-11T21:59:46 < mawk> but they seem to be the only ones to use them, with Temu also
2026-02-11T21:59:50 < mawk> I looked at reviews online and it's like 1/5 with everyone saying the same kind of stuff as me
2026-02-11T21:59:52 < mawk> I hope they return it to china so it can be delivered via a proper courier

2026-02-12T00:06:50 < qyx> but maybe I could just buy the whole thing..?
2026-02-12T00:08:22 < qyx> TH05? https://www.homebrainz.shop/sk/p/inteligentny-bluetooth-senzor-teploty-a-vlhkosti-s-led-displejom

2026-02-12T00:34:55 < mawk> qyx: xiaomi mija 2
2026-02-12T00:35:07 < mawk> apparently the old hardware revisions have better contrast and longer battery life
2026-02-12T00:35:50 < qyx> maybe not multiplexed
2026-02-12T00:36:26 < qyx> multiplexing reduces contrast and require more average current

2026-02-12T00:36:57 < mawk> the one you found is Tuya TH05
2026-02-12T00:37:03 < mawk> it supports BLE and zigbee
2026-02-12T00:37:18 < mawk> with this flashing tool https://pvvx.github.io/ATC_MiThermometer/TelinkMiFlasher.html
2026-02-12T00:37:19 < qyx> yes I see but idk if I can access it easily
2026-02-12T00:37:32 < mawk> the flashing tool is very easy
2026-02-12T00:37:46 < mawk> then you can set the advertisement like you want
2026-02-12T00:38:00 < mawk> I set mine as BTHome v2, then it's more or less standardized
2026-02-12T00:38:20 < mawk> then set advertising interval to 10s or whatever and enjoy the 3 years battery life
2026-02-12T00:38:41 < mawk> the one I have is https://nl.aliexpress.com/item/4000406818501.html
2026-02-12T00:39:20 < qyx> oh yes that chink smiley
2026-02-12T00:39:25 < mawk> lol
2026-02-12T00:39:40 < mawk> it was a bit of a pain to get them into the xiaomi home app, which was necessary to extract the encryption keys to do OTA with the custom firmware
2026-02-12T00:39:47 < mawk> I had to set my region to china then back to netherlands

2026-02-12T00:56:16 < karlp> I didn't have to use the xiaomi home app, but mine may have had old enough firmware on them when I bought them
2026-02-12T00:56:40 < karlp> I've reflashed them all OTA with atc or pvvx or something firmware, have them in HA for teh summerhouse monitoring

2026-02-12T01:00:17 < mawk> maybe this
2026-02-12T01:00:33 < mawk> or this if you use the custom firmware https://www.home-assistant.io/integrations/bthome/
2026-02-12T01:00:51 < mawk> which is better to conserve battery

2026-02-12T01:09:55 < mawk> I hope it works better this time
2026-02-12T01:10:17 < mawk> the one I had previously worked better than the original paxton tags on my proxmark, but not on the reader at the office
2026-02-12T01:12:28 < mawk> also if I change the carrier frequency from 125kHz to 118.8kHz then it magically works a lot better, it's very weird

2026-02-12T01:14:55 < mawk> well it's a passive tag
2026-02-12T01:15:06 < mawk> it gets the frequency from the reading device
2026-02-12T01:15:50 < mawk> for device → reader it's manchester modulation it's self-syncing normally, the frequency doesn't matter a lot
2026-02-12T01:16:22 < mawk> and for reader → device it's binary pulse length modulation, but again there is a sync word at the beginning so it should get the timing by itself
2026-02-12T01:16:37 < mawk> maybe I should've bought real NXP chips and not counterfeits

2026-02-12T13:28:02 < karlp> no, it's because it's too hard to puyt new parts into PLM, so they just use the parts that someone had managed to add at some point.

2026-02-12T17:00:24 < Steffanx> Lol
2026-02-12T17:01:15 < ventyl> someone got apparently offended when I said that microkernel is faster than Zephyr
2026-02-12T17:06:35 < Steffanx> Why would they? Assuming you have proper numbers on that claim.
2026-02-12T17:07:06 < Steffanx> *supporting that claim
2026-02-12T17:07:25 < ventyl> probably because people can get offended
2026-02-12T17:08:27 < ventyl> I have some numbers but I don't know if they are proper. I might have measured Zephyr wrong, in not most optimal configuration.
2026-02-12T17:09:12 < ventyl> like, I know they are not completely off as I found another benchmarks with roughly similar results
2026-02-12T17:09:41 < ventyl> but CMRX's edge is only around 10% so it is possible that after some configuration changes Zephyr would get faster than CMRX
2026-02-12T17:17:00 < jpa-> rtos speed rarely matters unless it is ridicuously slow
2026-02-12T17:17:36 < ventyl> latency may. and there's correlation

2026-02-13T21:06:15 < mawk> here's the code so far https://github.com/suut/rfal-mifare-classic/blob/master/X-CUBE-NFC6/Target/demo_polling.c#L524
2026-02-13T21:08:10 < mawk> after the initialization the keystream is given by crypto1_byte(&cs, 0, 0) which you xor with each incoming or outgoing byte to decrypt or encrypt
2026-02-13T21:09:00 < mawk> you also need to encrypt and decrypt the parity bits, so after each processed byte you encrypt or decrypt the parity bit by xoring with filter(cs.odd)
2026-02-13T21:09:13 < mawk> and that's all you need to do for the crypto
2026-02-13T21:09:42 < mawk> if you authenticated to block 0 you can only do stuff on blocks 0, 1, 2, 3; if you already authenticated and you want to read other sectors you need to do a nested authentication but I didn't implement it yet

2026-02-14T16:59:04 < mrec> is anyone here with hrtim experience? I wonder what the max bitrate is that can be sampled out with it
2026-02-14T16:59:18 < mrec> unfortunately I don't have any HRTIM parts/evbs here
2026-02-14T17:35:50 < zyp> what sort of setup do you have in mind?
2026-02-14T17:36:03 < jpa-> with the real 2GHz HRTIM or with the broken STM32H7 one?
2026-02-14T17:36:43 < zyp> probably doesn't matter, «sampled out» sounds like DMA, so it'll be bottlenecked by max DMA rate anyway
2026-02-14T17:37:37 < mrec> well I'd somehow like to sample out 100-200mbit
2026-02-14T17:37:38 < jpa-> with the real one i think you can output one pulse per each 240MHz clock or so
2026-02-14T17:37:54 < mrec> otherwise I'll wire up an FPGA
2026-02-14T17:38:14 < mrec> sample out at 100-200 mbit for various projects
2026-02-14T17:38:58 < jpa-> i don't know what that means either, but i assume it's pwm with per-cycle duty?
2026-02-14T17:39:38 < zyp> mrec, 100-200 mbit of arbitrary data? 1-bit wide?
2026-02-14T17:39:39 < mrec> per cycle duty; I only used the normal timers so far but the required sample rate was relatively low; I'm already looking forward to another project
2026-02-14T17:39:43 < mrec> yes
2026-02-14T17:40:03 < jpa-> 1 bit only? not the actual HR part?
2026-02-14T17:40:18 < mrec> eg. NRZI
2026-02-14T17:41:11 < mrec> why did you write broken STM32H7 HRTIM?
2026-02-14T17:41:31 < mrec> (mine doesn't have an HRTIM .. STM32H723
2026-02-14T17:41:33 < zyp> I don't think the HRTIM is helpful for what you want to do at all
2026-02-14T17:41:44 < jpa-> because e.g. stm32f3 hrtim has much higher resolution
2026-02-14T17:42:10 < jpa-> yeah, that application doesn't sound like good fit for hrtim
2026-02-14T17:43:48 < mrec> I think I should get one to study the capabilities of the hr timers...
2026-02-14T17:44:01 < zyp> also, the stm32 IO buffers don't tend to be rated for more than 100 Mb/s or so anyway, depending a bit on the part and setup
2026-02-14T17:46:38 < jpa-> e.g. STM32F334 HRTIM has 0.2 ns resolution, STM32H743 HRTIM has just 2 ns resolution
2026-02-14T17:47:02 < zyp> high resolution != high rate
2026-02-14T17:47:23 < jpa-> yeah, high resolution would be useful if you needed actual PWM and not just 1 bit data
2026-02-14T17:47:49 < mrec> they work with DMA? so should be reasonable fast no?
2026-02-14T17:48:09 < jpa-> if you only transfer 1 bit per DMA word, that's pretty wasteful
2026-02-14T17:48:31 < jpa-> on STM32H7 the high-resolution modes of HRTIM are somehow broken, you can activate it but instead of publishing errata, they just made the setting "reserved" in the reference manual
2026-02-14T17:48:36 < mrec> capture compare might be useful
2026-02-14T17:49:48 < zyp> mrec, I would suspect that a regular timer is already able to trigger DMA as fast as it can go, so HRTIM wouldn't help you there
2026-02-14T17:49:51 -!- Livio [~livio@user/livio] has joined ##stm32
2026-02-14T17:50:59 < jpa-> LTDC can do 150 MHz output, but i think you can't set the sync pulses to 0
2026-02-14T17:51:11 < zyp> also, doing weird stuff with timers and DMA requires preparing suitable DMA buffers, and there's no chance you're able to do that on the fly for 100-200 Mb/s
2026-02-14T17:51:36 < mrec> well burst frames that should be fine
2026-02-14T17:51:49 < mrec> no need to fully utilise the entire second
2026-02-14T17:51:56 < jpa-> HRTIM does have DMA burst mode support, so you could use the different channels to output the consecutive bits
2026-02-14T17:51:56 < zyp> jpa-, I suspect best bet might be just overclocking a SPI peripheral
2026-02-14T17:52:12 < mrec> or add an FPGA ;-)
2026-02-14T17:52:29 < zyp> yeah, that's what I'd do
2026-02-14T17:52:38 < jpa-> or DMA to GPIO and add an external parallel-to-serial shift register
2026-02-14T17:53:04 < jpa-> or use RP2350 :)
2026-02-14T17:53:36 < mrec> I think I have that one here somewhere too
2026-02-14T17:53:49 < jpa-> STM32H743 SPI can already do 100 MHz per the spec so wouldn't even need that much overclocking
2026-02-14T17:54:01 < zyp> it can? nice
2026-02-14T17:54:14 < zyp> I thought they typically were rated for like 20-30 MHz
2026-02-14T17:54:40 < jpa-> yeah, on the slower ones.. but with CPU running at 480 MHz, i guess the peripherals have fast transistors too
2026-02-14T17:57:22 < jpa-> ah, and you can get 200 Mbps out of quadspi in DDR mode, but only up to 2^32 bits until you have a tiny delay
2026-02-14T17:57:38 < mawk> even higher
2026-02-14T17:57:44 < mawk> than 100Mhz
2026-02-14T17:58:09 < mawk> I think cube lets you go up to 125 on H743, and then you can try to overclock it further
2026-02-14T17:58:19 < mawk> even if that makes cube sad
2026-02-14T17:59:11 < jpa-> i wouldn't put much weight on what cube UI lets or doesn't let you do, these were from datasheet
2026-02-14T17:59:37 < mrec> for some parts the UI is fine others definitely need hands on
2026-02-14T17:59:49 < jpa-> but yeah, looks like it is a rev Y vs. rev V difference, rev Y can do 133 MHz
2026-02-14T18:00:15 < mrec> thanks for pointing out to the stm32f3 part, I'll get some samples
2026-02-14T18:00:32 < jpa-> not sure why you would use stm32f3 for this particular task though
2026-02-14T18:00:45 < mawk> DS say 133MHz
2026-02-14T18:00:46 < mrec> no I just want to have a look at the capabilities
2026-02-14T18:01:12 < mrec> timers are powerful, so I wonder what I can do with high resolution timers if I can have some purpose for them
2026-02-14T18:01:21 < jpa-> i wonder if they have made any more recent STM32 with proper HRTIM
2026-02-14T18:01:49 < jpa-> STM32F334 is nice in that the HRTIM can drive stuff fast, but annoying in that it's a bit slow to actually calculate the waveforms that fast
2026-02-14T18:02:21 < jpa-> for example dtc-style motor control was difficult to get working when i needed to drive some 50krpm motors
2026-02-14T18:02:30 < mrec> hmm up to 72mhz only??
2026-02-14T18:03:14 < mrec> well I will check..

2026-02-14T22:42:17 < mawk> which NFC chip did you have already zyp ?
2026-02-14T22:42:29 < mawk> it's similar to ST25R95 iirc
2026-02-14T22:45:56 < mawk> ah yes ST95HF
2026-02-14T22:46:21 < mawk> it's NRND
2026-02-14T22:54:41 < ventyl> hm, so, is there any "DWT, ITM & ETM for noobs?" writeup?
2026-02-14T23:04:16 < zyp> mawk, it weren't ten years ago :)
2026-02-14T23:04:51 < mawk> lol yes I suppose
2026-02-14T23:05:08 < mawk> but now it's out of the supported stuffs by RFAL
2026-02-14T23:05:23 < mawk> although that doesn't really matter
2026-02-14T23:05:43 < zyp> ventyl, probably a bunch, what do you have in mind?
2026-02-14T23:10:46 < zyp> I can give you a quick rundown of how stuff fits together if you'd like
2026-02-14T23:10:54 < ventyl> zyp: i am revisiting the idea to trace kernel execution (possibly with orbtracy), but I need something more than register description and less than "use this complete solution and don't ask questions"
2026-02-14T23:11:19 < ventyl> now I am running L4 which shouldn't have problems with dumping TMIU output to SWO
2026-02-14T23:11:44 < zyp> right
2026-02-14T23:13:28 < zyp> so, ITM and ETM are separate trace sources producing entirely independent trace streams
2026-02-14T23:13:35 -!- umbramalison [~umbramali@188.74.90.42] has quit [Quit: %So long and thanks for all the fish%]
2026-02-14T23:14:29 < ventyl> if I understand it correctly, ITM is more like "SW-triggered" tracing and ETM is more towards "HW-triggered" tracing
2026-02-14T23:15:34 < zyp> ETM is «full execution trace», which in practice means it's a compact stream telling you instructions retired and branches taken/skipped/etc, leaving out anything you should be able to reconstruct yourself when you have the elf
2026-02-14T23:15:49 < zyp> typically doesn't give you data trace though
2026-02-14T23:16:20 < zyp> I would call ITM more like «event tracing»
2026-02-14T23:17:12 < zyp> you've got software events, which is what writing the ITM_STIMx registers produce, and hardware events that are produced by the DWT
2026-02-14T23:17:27 < zyp> so the DWT just feeds ITM
2026-02-14T23:18:43 < zyp> DWT can e.g. do PC samples at an interval, interrupt entry/exit tracing, comparator matches, etc
2026-02-14T23:21:29 < zyp> if you want to trace kernel events, there's limits to what you can do non-invasively
2026-02-14T23:21:30 < ventyl> so in theory, to trace callgraph, DWT + instrumentation is sufficient but can be done better via ETM?
2026-02-14T23:22:14 < ventyl> or else I have to expensively sample whole execution of kernel via DWT sampling
2026-02-14T23:22:57 < zyp> for callgraph without arguments, ETM should be able to do it noninvasively, but I'm not sure how hard decoding the stream would be, I haven't touched ETM much
2026-02-14T23:24:56 < ventyl> right now I need some insights into where the kernel spends cycles so I don't need arguments. these are mostly known for me
2026-02-14T23:26:34 < zyp> if you just need to know how many cycles are spent where, not why, orbtop is pretty useful
2026-02-14T23:28:16 < qyx> openocd can do that too and then any profiling tool? idk, i used something like that in the past
2026-02-14T23:29:42 < ventyl> zyp: for starters that will probably be sufficient
2026-02-14T23:41:00 < ventyl> zyp: is anywhere detailed how to setup ITM, DWT & friends in order to make orbtop worky?
2026-02-14T23:41:13 < ventyl> readme in orboculum seems to be generic in this regard
2026-02-14T23:43:06 < zyp> the example configuration is probably a good starting point
2026-02-14T23:47:45 < ventyl> will it work with openocd?
2026-02-14T23:47:58 < ventyl> so if I replace target-extended with localhost:1234, etc.
2026-02-14T23:50:30 < zyp> the command stuff is for setting up the target, it doesn't care how you're capturing the trace
2026-02-14T23:51:12 < ventyl> well, I am asking these dumb questions, because a lot of embedded stuff is: it works fine as long as you meet this long list of mostly-random preconditions
2026-02-14T23:51:20 < zyp> but yeah, orbtop will work with anything that'll capture an ITM stream and feed it on a TCP socket
2026-02-14T23:51:53 < zyp> yeah
2026-02-14T23:52:09 < ventyl> OK, so in this case I have to enable SWO which will be dumped into openocd and it will provide TCP socket for anyone to consume it
2026-02-14T23:52:28 < zyp> the issue with that stuff is that it's pretty low-level and clunky
2026-02-14T23:53:08 < ventyl> that's general description of pretty much the whole embedded :)
2026-02-14T23:53:59 < zyp> I've been wanting to make something more clever to detect and configure a target, but time and energy :p
2026-02-14T23:58:02 < zyp> the ITM and DWT stuff is easy enough, but configuring the trace output is vendor/chip specific
2026-02-14T23:58:21 < zyp> stm32 typically has you poke stuff in DBGMCU for that
2026-02-14T23:58:51 < zyp> the enableSTM32SWO command does that, but whether it supports your chip idk
2026-02-14T23:59:21 < ventyl> just by looking at the gdb file I guess it doesn't
2026-02-14T23:59:29 < ventyl> what bothers me is:
2026-02-14T23:59:49 < ventyl> 1. you actually have to figure out how to configure it
--- Day changed Sun Feb 15 2026
2026-02-15T00:00:09 < ventyl> 2. there's probably something like 1M++ embedded devs out there doing this and nobody is bothered
2026-02-15T00:00:35 < ventyl> but hey, MPU is hard, so I shouldn't be surprised
2026-02-15T00:01:03 < zyp> I sometimes like just probing the SWO pin with a scope for activity before spending time setting up the capture side of it
2026-02-15T00:01:42 < ventyl> that sounds so '80s
2026-02-15T00:02:20 < ventyl> will I have more or less luck with libtrace?
2026-02-15T00:02:39 < zyp> maybe, I haven't tried it
2026-02-15T00:03:04 < ventyl> OK, so there is infinite suffering potential there, stick to gdb
2026-02-15T00:03:19 < zyp> anyway, this is the important line in enableSTM32SWO: https://github.com/orbcode/orbuculum/blob/main/Support/gdbtrace.init#L980
2026-02-15T00:05:08 < zyp> typically what you need to do is poke the right bit(s) in DBGMCU_CR, do the prepareSWO command (generic, not chip specific), then the ITM and DWT config commands
2026-02-15T00:06:01 < ventyl> i am not there yet :)
2026-02-15T00:06:16 < zyp> which chip did you say you had? some l4?
2026-02-15T00:07:18 < ventyl> l432k(c)6

2026-02-15T00:16:32 < mawk> isn't SWO just UART ventyl ? if you select the UART framing mode
2026-02-15T00:16:49 < zyp> yup
2026-02-15T00:16:56 < mawk> then socat or whatever is able to convert that to TCP if you need TCP
2026-02-15T00:17:07 < ventyl> not so fast mawk. first you have to get it out of openocd

2026-02-15T00:20:26 < mawk> https://openocd.org/doc/html/Architecture-and-Core-Commands.html#ARM-CoreSight-TPIU-and-SWO-specific-commands
2026-02-15T00:20:34 < ventyl> mawk: I've found that SO question. it does not detail anything about setup other than enabling tpiu
2026-02-15T00:20:44 -!- rajkosto [~rajkosto@2a00:e90:2153:f00:0:ff:fe00:10] has quit [Ping timeout: 245 seconds]
2026-02-15T00:20:47 < ventyl> which seems fishy as the tool assumes that there is TCP port 6666 open
2026-02-15T00:21:06 < ventyl> well actually that tool talks to openocd interface, so it probably does the configuration on its own
2026-02-15T00:21:48 < zyp> «tpiu config» probably attempts both configuring the target and the probe to match
2026-02-15T00:22:11 < zyp> idk
2026-02-15T00:22:21 < ventyl> > idk :)
2026-02-15T00:22:55 < mawk> well you need an actual UART adapter on SWO
2026-02-15T00:23:03 < mawk> all openocd does is configure the target to start outputting on the port
2026-02-15T00:23:14 < zyp> doesn't the stlink do swo capture?
2026-02-15T00:23:20 < mawk> you might be able to use the stlink for that, but idk if it supports the right custom baudrates
2026-02-15T00:23:30 < ventyl> :)
2026-02-15T00:23:46 -!- Livio [~livio@user/livio] has quit [Quit: leaving]
2026-02-15T00:24:03 < ventyl> probably can
2026-02-15T00:24:08 < zyp> what right custom baudrates? :p
2026-02-15T00:24:14 < mawk> ah yes it's on -output
2026-02-15T00:24:22 < ventyl> there's a comment with a bunch of commands that mentions orbuculum
2026-02-15T00:24:36 < mawk> the default is to let a UART adapter do it, but you can tell it to use the probe, if it knows how to tell the probe to do it
2026-02-15T00:24:49 < ventyl> but the sole fact that I have two embedded devs who work for years with STM32 and they are clueless is itself funny
2026-02-15T00:25:19 < mawk> well the baud rate on SWO depends on the core frequency zyp right? if I understand correctly
2026-02-15T00:25:56 < zyp> with a configurable divider, so you can kinda make it whatever
2026-02-15T00:25:58 < mawk> as you want the baud rate to divide nicely into the core frequency
2026-02-15T00:26:07 < mawk> hmm
2026-02-15T00:27:45 < zyp> mawk, but I mean, you don't have to divide it, here's 168 Mbaud SWO: https://bin.jvnv.net/file/oL5F9.png
2026-02-15T00:27:47 < mawk> the docs show a nice example using a FT232, if you modify it instead with $tpiu configure -output :6666 it should forward to TCP port 6666
2026-02-15T00:28:01 < mawk> lol that's a lot of bauds
2026-02-15T00:28:19 < zyp> it's a f4 at full speed with no division :)
2026-02-15T00:29:07 < zyp> orbtrace tops out somewhere around 70 Mbaud though
2026-02-15T00:29:56 < zyp> manchester mode can do close to 100 Mbaud, but has an encoding efficiency of 50% rather than 80%
2026-02-15T00:30:33 < zyp> so in practice either can give you around 50 Mb/s of actual throughput
2026-02-15T00:33:05 < ventyl> nah, I can guess the frequency until judgement day
2026-02-15T00:33:21 < ventyl> For the TPIU embedded in Cortex-M3 or M4, this is usually the same frequency as HCLK. 
2026-02-15T00:33:32 < ventyl> what is usually and what it is is if it isn't HCKL?
2026-02-15T00:33:41 < ventyl> sigh
2026-02-15T00:34:58 < zyp> I think for pretty much all midrange MCUs it'll be HCLK/SYSCLK
2026-02-15T00:35:17 < zyp> but highend MCUs tend to have more complex trace infrastructure
2026-02-15T00:36:28 < ventyl> just, it doesn't accept it
2026-02-15T00:36:43 < zyp> openocd?
2026-02-15T00:36:59 < ventyl> yeah
2026-02-15T00:37:08 < ventyl> SWO frequency is not suitable. Please choose a different frequency.
2026-02-15T00:37:23 < zyp> that'll be limited to whatever the stlink can do
2026-02-15T00:37:25 < zyp> try 1M
2026-02-15T00:37:45 < ventyl> so the HCLK/SYSCLK is actually upper limit?
2026-02-15T00:37:54 < ventyl> or that parameter will force openocd to figure out prescaler?
2026-02-15T00:38:28 < ventyl> nope, 1M won't do it. 200k neither
2026-02-15T00:39:14 < zyp> try 16M
2026-02-15T00:39:23 < ventyl> euromillions? :)
2026-02-15T00:39:37 < ventyl> nyet
2026-02-15T00:39:48 < zyp> hmm, nah
2026-02-15T00:40:19 < ventyl> shouldn't something get enabled on the device side? like, clock, swo itself... ?
2026-02-15T00:40:34 < ventyl> can it be enabled completely from openocd side with no firmware preparation?
2026-02-15T00:41:16 < ventyl> im asking because you know, many embedded things are like: it works perfectly once you enable this completely unobvious and almost undocumented thing first
2026-02-15T00:42:25 < zyp> I generally don't have the target firmware touch anything trace-related at all (besides writing ITM_STIM registers for software events, after checking that the ITM channels are enabled)
2026-02-15T00:43:02 < zyp> but you can also have the firmware enable SWO almost autonomously
2026-02-15T00:43:52 < zyp> only thing firmware can't do is switch the SWJ-DP into SWD mode to switch TDO to SWO
2026-02-15T00:44:49 < ventyl> lol i won the lottery
2026-02-15T00:44:51 < ventyl> 72M works
2026-02-15T00:44:55 < ventyl> fuck knows why
2026-02-15T00:45:13 < ventyl> "works" := at least openocd doesn't complain
2026-02-15T00:47:11 < ventyl> > SWO pin data rate adjusted by adapter to 24000000 Hz
2026-02-15T00:47:41 < ventyl> I am somewhat pessimstic about ability of that flat ribbon cable of sustaining this clock rate...
2026-02-15T00:47:51 < qyx> it works
2026-02-15T00:48:08 < zyp> the cable is fine, it has alternating grounds
2026-02-15T00:48:20 < zyp> would be more worried about the stlink actually capturing
2026-02-15T00:48:31 < qyx> it works on v3
2026-02-15T00:49:12 < qyx> idk if over vcp
2026-02-15T00:49:19 < ventyl> one concept I can't grasp is why 72M was accepted as input and then converted to 24M
2026-02-15T00:49:48 < zyp> some st forum post says the max freq is 12M at 3.3V
2026-02-15T00:50:32 < ventyl> so, actually getting SWO broken out is just one part, now I need to configure ITM & friends and then connect orbuculum to my just created TCP port
2026-02-15T00:50:50 < zyp> you can just connect orbtop directly to it
2026-02-15T00:50:52 < ventyl> and it all took only two hours
2026-02-15T00:51:17 < zyp> before you do that, I'd nc | hexdump first, just to see you're getting anything
2026-02-15T00:51:42 < ventyl> without calling orbuculum gdb commands, line should be dead, shouldn't it?
2026-02-15T00:52:04 < zyp> depends if openocd already poked the target or not
2026-02-15T00:52:17 < zyp> but yeah
2026-02-15T00:52:54 < ventyl> its dead
2026-02-15T00:53:16 < ventyl> so now I feed gdb with commands from orbuculum example
2026-02-15T00:53:27 < zyp> line will be idle when the target is not executing
2026-02-15T00:53:47 < zyp> or if no events are generated
2026-02-15T00:54:19 < zyp> skip the enableSTM32SWO and prepareSWO lines and just do the rest
2026-02-15T00:54:27 < zyp> see if that gets you anything
2026-02-15T00:55:01 < ventyl> monitor traceswo is needed?
2026-02-15T00:55:23 < ventyl> whatever #yolo
2026-02-15T00:56:34 < zyp> idk what that is
2026-02-15T00:59:26 < ventyl> well, nothing goes throuhg
2026-02-15T00:59:40 < ventyl> but I called enableSTM32SWO, how much damage that created?
2026-02-15T00:59:49 < zyp> probably none
2026-02-15T00:59:58 < zyp> try doing the prepareSWO line as well
2026-02-15T01:00:35 < ventyl> and those magic numbers in the line do mean what?
2026-02-15T01:01:04 < zyp> core freq, target freq, and then some order of mode, let me look up which mode you wanted
2026-02-15T01:01:34 < zyp> 0 0
2026-02-15T01:02:23 < ventyl> target freq := 72M in my case?
2026-02-15T01:02:38 < ventyl> or is it arbitrary number I choose?
2026-02-15T01:02:52 < zyp> core freq/target freq is just used to calculate the divider ratio, so I typically treat them as a ratio and do something like 2 1 for 1/2
2026-02-15T01:03:18 < zyp> target freq probably needs to match whatever the stlink is configured to capture
2026-02-15T01:03:30 < ventyl> probably? :)
2026-02-15T01:04:08 < zyp> orbtrace in manchester mode is autodetecting speed, so I usually don't think too hard about it, just need it low enough that it's reliably captured
2026-02-15T01:04:58 < ventyl> (gdb) monitor traceswo 72000000
2026-02-15T01:04:58 < ventyl> invalid command name "traceswo"
2026-02-15T01:05:01 < ventyl> ummm
2026-02-15T01:05:30 < zyp> where is that from?
2026-02-15T01:05:32 < qyx> hm I can't find programming connectors
2026-02-15T01:06:01 < ventyl> the command? from orbuculus readme
2026-02-15T01:06:15 < zyp> ah, ignore that, that's when using a bmp
2026-02-15T01:06:56 < ventyl> so nothing is complaining but nothing also goes through
2026-02-15T01:07:10 < ventyl> orbtop connects but says 0 samples
2026-02-15T01:07:13 < zyp> and you have the target running?
2026-02-15T01:07:21 < ventyl> yes
2026-02-15T01:07:42 < ventyl> i've pointed orbtop to the elf file which is actually flashed in the MCU
2026-02-15T01:08:05 < zyp> can you scope the SWO pin? does it show any activity, or does it idle high or low?
2026-02-15T01:08:18 < ventyl> i'd probably rather commit harakiri
2026-02-15T01:08:42 < ventyl> hm, maybe I can scope it on stlink side
2026-02-15T01:09:31 < zyp> I mean, you want to know if it's the target or the stlink that's not configured right
2026-02-15T01:09:42 < ventyl> nah, scope probably has dead battery
2026-02-15T01:09:50 < ventyl> maybe harakiri isn't the worst idea actually
2026-02-15T01:12:09 < ventyl> just as a thought experiment, lets assume both are misconfigured
2026-02-15T01:12:16 < ventyl> how to fix the configuration?
2026-02-15T01:14:36 < ventyl> Error: BUG: refcount AP#0 still 1 at exit

2026-02-15T02:52:54 < mawk> my MFC code is working perfectly, it can read the whole 1K card in 530 ms but it can surely be faster if you have a faster MCU and tweak the timing and such
2026-02-15T02:53:10 < mawk> I made it relatively reader-agnostic
2026-02-15T02:53:12 < mawk> https://github.com/suut/rfal-mifare-classic/blob/master/mf1/mf1.h
2026-02-15T02:54:00 < mawk> if you modify send_receive_raw to use the raw commands and then define READER_TYPE_ST25R95 to that it uses the old parity framing mode like on ST95HF it should work easily
2026-02-15T02:54:28 < mawk> then example code for reading the whole card is here https://github.com/suut/rfal-mifare-classic/blob/master/X-CUBE-NFC6/Target/demo_polling.c#L283
2026-02-15T02:54:34 < mawk> using default keys, for a 1K card
2026-02-15T02:55:11 < mawk> there are 320, 1024 and 4096 bytes cards, but the 320 are super rare ("Mifare Mini")
2026-02-15T02:57:55 < mawk> some parts of the code is under GPL so I need to rewrite it to be MIT or whatever
2026-02-15T03:01:35 < mawk> the hot new thing is ST25R3916B catphish 
2026-02-15T03:03:40 < mawk> top of the line now is ST25R300 withs lots of output power, then you also have ST25RN300 for integration in phones and all that; but for that one they put the mifare classic capabilities under NDA
2026-02-15T03:05:41 < mawk> ST25R3916(B) is in flipper zero or hydra nfc; it can even do sniffing
2026-02-15T03:09:15 < qyx> mifare? there is also ultralight
2026-02-15T03:09:30 < qyx> which was very common
2026-02-15T03:10:40 < mawk> ultralight is still current, they have AES versions now
2026-02-15T03:11:00 < mawk> there's no need for special modes to read these, only mifare classic is special
2026-02-15T03:11:29 < mawk> because it encrypts the parity bits instead of following ISO-14443-A normally; it was done like in the 90s to simplify the IC design and be able to feed the demodulated data directly to the encryption circuitry
2026-02-15T03:16:44 < qyx> uhm
2026-02-15T03:17:48 < mawk> of course all this shit is under NDA, NXP loves NDAs, but you can still talk to it using a normal reader provided you know the right commands
2026-02-15T03:26:02 < mawk> I ordered some contactless javacards from NXP, but I doubt I could get anything out of them, all the info is even more secretive than regular NFC tags
2026-02-15T03:26:17 < mawk> I'll be happy if I can do hello world on it

2026-02-15T14:55:44 < jpa-> how silly of ftdi to not document the protocol
2026-02-15T14:59:32 < ventyl> zyp: fun stuff: jean claude van AI claims that not even L4 can put ETM output via SWO. But that claim sounds fishy.
2026-02-15T15:02:17 -!- specing [~specing@user/specing] has joined ##stm32
2026-02-15T15:04:51 < zyp> ventyl, that's wrong, according to the documentation I read yesterday it can
2026-02-15T15:05:41 < zyp> H7 can't, unsure about H5, I expect everything else can
2026-02-15T15:05:55 < zyp> (excluding the m0/m0+ parts that doesn't have ETM)
2026-02-15T15:07:22 < ventyl> source is some segger paper promoting their systemview :)

2026-02-15T15:42:07 < zyp> so, the thing is that in most mid-end cortex-m, there's a simplified «cortex-m TPIU» that handles both the SWO and the parallel TRACE pins
2026-02-15T15:43:31 < zyp> ITM and ETM are muxed and fed into this and the TPIU doesn't care what sort of trace data arrives on the ATB, it just feeds it out through the configured interface
2026-02-15T15:46:13 < zyp> in more complex chips, vendors goes picking parts from the coresight libraries, and the blocks there are either SWO-only or parallel TPIU-only
2026-02-15T15:46:44 < zyp> so chips like H7 has SWO and TPIU as two separate blocks
2026-02-15T15:47:29 < zyp> and the ATB stream fed to the SWO block is often tapped directly from the ITM stream before multiplexing it with the ETM stream that gets fed to the parallel TPIU
2026-02-15T15:47:57 < zyp> when this is the case, SWO can only do ITM
2026-02-15T15:49:18 < zyp> see e.g. https://bin.jvnv.net/file/r8tSF.png
2026-02-15T15:53:09 < zyp> compare that to your chip: https://bin.jvnv.net/file/UnnOc.png

2026-02-15T15:59:04 < ventyl> yeah, that's why I consider that claim fishy. TPIU integration diagram on H7 looks completely different to one on L4
2026-02-15T15:59:51 < ventyl> nevertheless it is all futile if SWO is not broken out to SWD connector on this particular device :)

2026-02-17T21:43:32 < veverak> we have this weird thing at work, we have CAN devices which during _use_ are trivial to work with: we have 3 unique devices per bus, so we can have fixed address for each device on the bus that represents its role
2026-02-17T21:43:58 < veverak> But during maintenance or infrastructure work, devices of same "role" are connected on single bus (up to 30)
2026-02-17T21:44:35 < veverak> Is there some common/standard way to distribute node ids automatically? I don't mind that it is slow
2026-02-17T21:45:11 < veverak> (during the maintenance, we can't pre-allocate the nodei ds to the devices as there is now way of telling which will get connected)

2026-02-18T00:06:55 < qyx> veverak: yes I did it exactly the way zyp describes, it is dumb, I don't like it
2026-02-18T00:09:42 < qyx> it makes the addressing stateful, makes your life harder if you need to gateway between busses and you still need to handle duplicate ids
2026-02-18T00:10:25 < qyx> and as you are voiding some CAN features that way anyway, it doesn't make sense to preallocate them at all
2026-02-18T00:11:08 < qyx> I wohld split the 29bit ID into 16 bit "flow id", 8 bit "frame id"
2026-02-18T00:11:52 < qyx> and generate flow id per-packet (eg. hashing the data or as a part of the packet MAC)
2026-02-18T00:12:13 < qyx> frame id is 0-255 depending on the frame position in the packet
2026-02-18T00:13:01 < qyx> that way you are spreading possible collisions to be per-packet instead of per-device, which you have to handle in all cases (a packet can get lost)
2026-02-18T00:17:20 < veverak> wat, but how you can tell which device shall accept the message?

2026-02-18T00:18:37 < qyx> zyp: isotp doesn't fix anything, thats for the start
2026-02-18T00:18:50 < zyp> it's orthogonal to enumeration in any case
2026-02-18T00:19:03 < qyx> yes
2026-02-18T00:19:10 < veverak> now that I think about, given that during maintenance it's master/slave comms anyway...
2026-02-18T00:19:17 < qyx> anyway the key is to avoid enumeration
2026-02-18T00:19:25 < veverak> I can just assume that everybody gets each message and put target id in the data payload for the message
2026-02-18T00:19:29 < zyp> as for the stateful argument, enumeration necessarily is stateful
2026-02-18T00:19:38 < qyx> and don't tell me you are waking up the device based on address filters
2026-02-18T00:19:46 < qyx> nobody is doing that except automotive
2026-02-18T00:20:20 < qyx> and even they don't really know the exact reason
2026-02-18T00:21:17 < qyx> and if you are hashing "long-id" j to "short id" in a deterministic manner, you can still setup filters
2026-02-18T00:21:23 < catphish> veverak: you essentially need a DHCP protocol
2026-02-18T00:23:21 < qyx> my point still holds, any enumeration or/and stateful anything on this level makes more problems than solves
2026-02-18T00:24:10 < zyp> I'll take stateful enumeration over fragmentation if I can otherwise get away without the latter
2026-02-18T00:24:32 < catphish> veverak: i think it's worth pointing out that devices in a CAN network don't have addresses, addresses are for functions rather than devices, so if you have multiple devices listening to the same ID, control them all at once
2026-02-18T00:24:57 < catphish> i'm sure you know this, but it's kind of an important distinction that makes my DHCP suggession less senible
2026-02-18T00:25:01 < catphish> *sensible
2026-02-18T00:26:34 < veverak> catphish: I can do broadcast
2026-02-18T00:26:53 < veverak> basically, what I wanted to sent over CAN on higher layer are protobuf messages target to device based on address
2026-02-18T00:27:28 < veverak> I did not realized that I don't mind if "each device will accept the message and parse it" so I might as well put the ID into the protobuf
2026-02-18T00:27:38 < qyx> so target addressing and fragmentation :>
2026-02-18T00:28:02 < veverak> all that I need is just robust way to split the protobuf payload into multiple can messages and re-assemble them
2026-02-18T00:28:24 < qyx> yes, and add an aggregated MAC
2026-02-18T00:28:52 < veverak> aggregated MAC?
2026-02-18T00:29:35 < qyx> message auth tag, whatever which is covering the whole packet
2026-02-18T00:30:09 < qyx> after a lot of hassle implementing the allocation/enumeration way I can conclude never again
2026-02-18T00:30:23 < qyx> there are many practical problems with that
2026-02-18T00:30:51 < qyx> it needs various timers and timeouts, all gateway devices need to maintain that database
2026-02-18T00:31:07 < qyx> it needs periodic refreshing of the allocation table
2026-02-18T00:31:11 < qyx> etc.
2026-02-18T00:31:15 < veverak> I have master/slave relationship, no busses
2026-02-18T00:31:28 < veverak> I mean, just single bus, no connection between busses
2026-02-18T00:31:53 < veverak> The whole thing is just smart-case for devices that can communicate over CAN so we can update the firmware in those at mass (in the case)
2026-02-18T00:32:04 < qyx> ok I have "splitters" because I needed to implement a tree topology
2026-02-18T00:34:14 < veverak> yeah, I just forgot that I have single master on the bus that controls the flow of stuff anyway
2026-02-18T00:35:05 < qyx> also, can is a retarded bus, but whatever
2026-02-18T00:36:38 < veverak> that's irrelevant
2026-02-18T00:36:38 < zyp> less so when you're not shoehorning fragmentation into it
2026-02-18T00:37:10 < veverak> whenever technology X is ok/nok is irrelevant in the scenario that company already sold too many units and htat is what I have to work with
2026-02-18T00:37:55 < veverak> anyway, I've got my answer, just need to solve fragmentation, detach
2026-02-18T00:39:21 < qyx> zyp: fragmentation is needed to make any use of can besides being a "honored inteligent wire"
2026-02-18T00:39:47 < qyx> that's why it is retarded
2026-02-18T00:40:10 < qyx> because it is not suitable for any current purpose, remember it is 2026
2026-02-18T00:41:05 < bitmask> hello
2026-02-18T00:41:06 < qyx> and every single relevant can user implementes fragmentation and encryption on top of that abomination

2026-02-18T13:52:37 < jpa-> meh, bug of the day
2026-02-18T13:53:08 < jpa-> i wasn't disabling interrupts when jumping from bootloader to main firmware, and some shared platform code was setting up systick during the bootloader
2026-02-18T13:53:46 < jpa-> and there was a small space where the main firmware wasn't expecting systick before it has started.. so depending on exact timing it would crash sometimes

2026-02-18T13:57:32 < ventyl> i had that, it caused pretty weird errors
2026-02-18T13:57:57 < jpa-> yeah, bss wasn't yet initialized etc, but the code managed to run pretty far before crashing
2026-02-18T13:57:58 < ventyl> it took me fair amount of time realizing WTF is really going on

2026-02-18T13:58:55 < ventyl> in my case, it was actually by design. somehow I assumed that if you enable systick and then *immediately* boot CMRX kernel, systick will never arrive before kernel is bootstrapped and ready to receive it
2026-02-18T13:59:06 < ventyl> well, it turned out in certain cases this is a false assumption
2026-02-18T13:59:24 < ventyl> most notably, systick work quite weird in qemu

2026-02-18T14:51:55 < jpa-> for some funny reason RP2350 starts fetching from XIP flash one word before what was actually needed for the interrupt, which made me think it was going into pendsv and not systick

2026-02-19T18:40:08 < catphish> i have made an irritating design mistake, but i wonder if i might be lucky, i'm at a very late stage in designing something with a H750 and i need to save some data in flash memory. i have just realised that the H750 only has one flash sector :'( however several people claim that it might have more unadvertized sectors
2026-02-19T18:43:00 < qyx> how are you even using h750 without any external flash?
2026-02-19T18:43:44 < catphish> i guess my program is small
2026-02-19T18:44:09 < catphish> i was only looking at RAM when i chose it, and i guess i just never used much program space

2026-02-19T20:27:10 < mawk> nice
2026-02-19T20:27:22 < mawk> we use mpu to hide encryption keys which are global to all the devices in the field
2026-02-19T20:27:44 < mawk> and now that the RED and CRA bullshit is in effect you have to do something 
2026-02-19T20:29:56 < qyx> what's something
2026-02-19T20:31:40 < catphish> well that is lucky, the H750 does indeed have more flash than advertized, probably best not to rely on this, but it appears to work on the chips i hae in hand, which saves me a huge headache

2026-02-19T21:18:54 < catphish> oh, it's not that at all, i'm just being an idiot and trying to use HAL_Delay in an interrupt
2026-02-19T21:20:57 < catphish> i guess that will work if i just fix the interrupt priotiries
2026-02-19T21:25:46 < catphish> odd, systick has a much higher priority, this should be working already
2026-02-19T21:27:03 < mercenary> unless something somewhere disabled all interrupts
2026-02-19T21:30:29 < catphish> oh, i think higher number = lower priority
2026-02-19T21:30:46 < qyx> you think right
2026-02-19T21:32:00 < catphish> i've set my 1ms maintenance timer to a lower priority than systick, fingers crossed

2026-02-20T20:51:40 < mawk> >The formal vulnerability record for OpenClaw is extensive. A security audit conducted on January 25, 2026, by the Argus Security Platform (filed as GitHub Issue #1796 by user devatsecure) identified 512 total vulnerabilities, eight classified as critical, spanning authentication, secrets management, dependencies, and application security. Key find

When he contacted Steinberger, the founder reportedly said security "isn't really something that he wants to prioritize."
2026-02-20T20:51:58 < mawk> insane shit
2026-02-20T20:59:15 < specing> what even is openclaw
2026-02-20T21:07:19 < qyx> your personal clown
2026-02-20T21:11:05 < mawk> lol
2026-02-20T21:11:49 < mawk> I'm trying to innovate my javacard into a FIDO2 authentication card
2026-02-20T21:12:09 < mawk> so I can smartcard my way onto websites like a true government employee 
2026-02-20T21:13:52 < qyx> fido2 is too new for govs
2026-02-20T21:14:47 < mawk> I can also do FIPS
2026-02-20T21:15:28 < mawk> currently I innovated it as a counterfeit Mifare Plus card, with weird behavior
2026-02-20T21:15:34 < mawk> but mifare plus is useless 
2026-02-20T21:15:55 < mawk> it's basically AES mifare classic with double the memory
2026-02-20T21:16:55 < mawk> there's also an EMV credit card applet on it but unless mastercard signs my key I can't use it for much
2026-02-20T21:36:01 < qyx> how can I turn off that dumb kicad antifeature snapping cursor to any graphics along virtual lines after you "touch" them before
2026-02-20T21:36:37 < qyx> it makes me want to axe-shape my computer
2026-02-20T21:48:33 < jpa-> mawk: well prioritizing security in openclaw is like prioritizing non-flammability in gasoline
2026-02-20T21:49:26 < mawk> lol
2026-02-20T21:49:58 < mawk> the javacard came with custom keys, so I googled around, found a bunch of random keys of aliexpress cards, and on the third try I got in
2026-02-20T21:50:09 < mawk> which is lucky because the card locks up after too many bad attempts
2026-02-20T21:50:23 < mawk> I wonder if I can use that to remotely lock up people's card
2026-02-20T21:50:34 < mawk> I should try with an old credit card

2026-02-20T22:05:34 < qyx> 7816
2026-02-20T22:06:05 < mawk> they're dual interface

2026-02-20T22:06:30 < mawk> so I talk to it contactless
2026-02-20T22:07:26 < qyx> once I had an idea of turning a common iso7816 card into an authenticator with some embedded-compatible method/cipher
2026-02-20T22:07:56 < qyx> before trustzone was a thing
2026-02-20T22:08:19 < mawk> with a javacard applet?
2026-02-20T22:08:25 < mawk> or a card preloaded with crypto shit
2026-02-20T22:08:50 < qyx> with an applet
2026-02-20T22:09:01 < mawk> I have seen some SIM cards with a PGP applet
2026-02-20T22:09:05 < mawk> but I haven't tried to talk to it
2026-02-20T22:09:11 < mawk> ah that you made yourself?
2026-02-20T22:09:14 < qyx> because common pkcs11/15 cards were not using the *right* crypto
2026-02-20T22:09:17 < mawk> all this javacard tools are mysterious 
2026-02-20T22:09:28 < mawk> since NXP got them and not IBM anymore you can't even find them
2026-02-20T22:09:29 < qyx> also not common
2026-02-20T22:09:36 < mawk> you have to use the opensource stuff
2026-02-20T22:10:03 < qyx> I wohld say common LTE SIM cards are capable enough
2026-02-20T22:10:10 < qyx> but they are locked
2026-02-20T22:10:18 < mawk> I can put a big NDEF container applet on the card and use it for regular data that a smartphone can talk to without special software 
2026-02-20T22:10:18 < qyx> and thats sad
2026-02-20T22:10:24 < mawk> well you can buy unfused SIMs just fine
2026-02-20T22:10:54 < mawk> see this https://www.fi.muni.cz/~xsvenda/jcalgtest/
2026-02-20T22:11:02 < qyx> you still need to mess with the software on them
2026-02-20T22:11:02 < mawk> it's a benchmark of javacards that tells you which algo they have
2026-02-20T22:11:06 < mawk> so you can buy the right one
2026-02-20T22:12:46 < mawk> my card has a nxp chip so it can do mifare classic/plus/desfire but it's again all under NDA and I can't dump the existing applets to look at them
2026-02-20T22:12:51 < mawk> sad
2026-02-20T22:16:21 < qyx> sadly I have too much <redacted> to do I can't play with smartcards now

2026-02-21T14:40:37 < mawk> is it a project that involves destroying stroopwafels qyx 
2026-02-21T14:48:49 < qyx> no, it is "shit", mawk
2026-02-21T14:49:33 < mawk> :(
2026-02-21T14:50:04 < mawk> I delete all the mifare and credit card shit from the javacard, and I put a NDEF applet instead; now my phone recognizes it and I can write obscenities to it
2026-02-21T14:51:42 < qyx> now that you are a NDEF expert, can the phone *append* NDEF records to the card?
2026-02-21T14:51:56 < qyx> or it must read them all, update and rewrite the whole card?
2026-02-21T14:52:23 < mawk> yeah you need to read first it's TLV encoded so you need to know where the old data ends
2026-02-21T14:52:33 < mawk> but it's usually very quick to read
2026-02-21T14:52:36 < qyx> so appending is not managed?
2026-02-21T14:52:45 < qyx> ou have to find the end and append yourself?
2026-02-21T14:53:16 < mawk> yeah you have to find the end yourself; maybe android has APIs for this idk, but at the low level it's just a big blob of data that the card has no idea about
2026-02-21T14:53:41 < qyx> that's sad
2026-02-21T14:54:26 < qyx> in the past, maybe 10-15y ago, I had a request to do a "beacon" for orienteering to tap to write the time and beacon's signature
2026-02-21T14:54:40 < qyx> that was before IoT and widespread mobile internet was a thing
2026-02-21T14:54:46 < qyx> and NFC was emerging
2026-02-21T14:55:08 < qyx> then the guy died
2026-02-21T14:55:18 < mawk> lol
2026-02-21T14:56:16 < qyx> so I wanted to just append NDEF records to a NFC card
2026-02-21T14:56:50 -!- Livio [~livio@user/livio] has quit [Remote host closed the connection]
2026-02-21T14:57:03 < qyx> and even read the card with a phone and post your results online after the event
2026-02-21T14:57:11 < qyx> hm it could have been 2012-3 or so
2026-02-21T15:01:25 < mawk> with the higher end type 4 NFC tags you could maybe make it so that removing the card during the read-modify-write doesn't leave the card in a borked state, with either wrong data or corrupted data
2026-02-21T15:01:36 < mawk> but on a cheap regular tag there will always be this risk
2026-02-21T15:01:58 < mawk> unless you're writing less than 1 block 
2026-02-21T15:02:41 < mawk> which is like 4 bytes for the ultralight/nt2xx stuff
2026-02-21T15:03:59 < qyx> couldn't you pre-write the TL part of the TLV?
2026-02-21T15:04:29 < qyx> which should actually be the case even if you are writing sequentially
2026-02-21T15:05:00 < qyx> if you fail in the middle, TL is still valid and the next write will skip the unfinished data block (the V part)
2026-02-21T15:06:27 < mawk> you might have to rewrite all or part of the existing data to append your new data; it's recoverable if you make the reader smart and it keeps retrying to write as long as the card is there, but if the guy walks away then his card has invalid data
2026-02-21T15:07:54 < mawk> but you can just skip the NDEF encoding and put the data you want on the card, then it won't nicely scan or open a link but with a custom application you can do what you want, and then you can do stuff like only writing to new blocks to leave the old data alone
2026-02-21T15:12:50 < mawk> yeah apparently with the higher end type 4 tags like NTAG424 you can write up to 255 bytes at once, so if the card gets teared off within that window the data is still safe, so you could still do it with NDEF just fine
2026-02-21T15:17:17 < qyx> nah, it is a bit too late now
2026-02-21T15:17:43 < mawk> resurrect the guy
2026-02-21T15:21:26 < mawk> now I have a 32K NDEF applet on the card
2026-02-21T15:21:28 < mawk> beautiful
2026-02-21T15:21:59 < mawk> I'm trying to compile a counterfeit yubikey applet to put on it so I can use it to decrypt my laptop at boot so that when I lose the card I lose all my data
2026-02-21T15:23:36  * qyx marking mawk as a local javacard applet expert
2026-02-21T15:23:42 < mawk> lol
2026-02-21T15:28:42 < BrainDamage> mawk: the solution for faults/loss of hw tokens is to have multiple ones that can auth
2026-02-21T15:28:54 < BrainDamage> and given you're working with cheap cards, once you have the workflow it should be easy
2026-02-21T15:29:02 < mawk> yeah
2026-02-21T15:30:01 < BrainDamage> maybe hand one to momo as sign of mutual trust
2026-02-21T15:31:03 < mawk> lol
2026-02-21T15:31:09 < mawk> he still has my credit card it's already enough
2026-02-21T15:33:53 < qyx> if you can get a buyable smartcard working over iso7816 for IoT auth, I have an application
2026-02-21T15:35:01 < qyx> what was the link with card types and their capabilities?
2026-02-21T15:39:48 < mawk> this https://www.fi.muni.cz/~xsvenda/jcalgtest/knowledgebase.html
2026-02-21T15:40:11 < mawk> why do you want the contact interface? contactless looks cooler
2026-02-21T15:41:31 < mawk> there's a siren and some guy saying something with a megaphone next to my apartment
2026-02-21T15:41:39 < mawk> I think the city hall is on fire
2026-02-21T15:41:54 < mawk> >P 1 BDH-01 OMS brandmelding Stadskantoor Stationsplein Delft 155530
2026-02-21T15:41:56 < mawk> I need to go look
2026-02-21T15:43:00 < qyx> because I need to put it in a slot in a device
2026-02-21T15:43:20 < qyx> hm about 30-40% of the listed cards support ecdsa
2026-02-21T15:45:50 < mawk> you can put a nfc reader in that slot, it's as easy to program as a contact reader; everything is contactless now and it's the same interface in the end
2026-02-21T15:45:56 < mawk> then you can also do something with phones in the future
2026-02-21T15:47:14 < qyx> please think as a responsible human
2026-02-21T15:47:42 < mawk> lol

2026-02-21T21:36:30 < mawk> it's the state of the art
2026-02-21T21:36:42 < mawk> not some custom javacard applet or antique PKCS#11 token
2026-02-21T21:37:27 < mawk> you need a NDA with NXP to talk to it but fortunately it's been reverse engineered
2026-02-21T21:37:34 < mawk> fuck NXP and their NDAs

2026-02-21T22:51:09 < qyx> mawk: isn't desfire nfc only?
2026-02-21T22:51:12 < mawk> yeah
2026-02-21T22:51:20 < mawk> well, usually
2026-02-21T22:51:38 < mawk> desfire runs on smart cards, like the smartmx platform of NXP
2026-02-21T22:51:50 < mawk> there's nothing that prevents it from being used by the contact interface I would think
2026-02-21T22:52:04 < mawk> but you need to ask the right person to enable desfire on your javacard
2026-02-21T22:52:56 < mawk> but it's probably locked to contactless
2026-02-21T22:56:21 < mawk> if you really want contact only there are a couple of opensource applets, openfips and fido2
2026-02-21T22:56:29 < mawk> or also openpgp
2026-02-21T22:56:32 < mawk> lots of choices
2026-02-21T23:00:21 < mawk> of course you can get a smartcard with this already loaded, it will be cheaper in development time but more expensive in cost
2026-02-21T23:00:37 < mawk> although it's not that incredibly complicated to make tooling to install the blank cards
2026-02-21T23:01:00 < mawk> there are several applications to do it, like global platform shell or global platform pro

2026-02-23T11:09:18 < mawk> what's an off the shelf device to continuously sample a voltage and stream to a pc; last time I had a regular fluke multimeter with a pc cable but that's expensive 
2026-02-23T11:12:08 < mercenary> are you .... describing a cheap USB oscilloscope there?
2026-02-23T11:24:21 < zyp> given the mention of a multimeter, I assume a slower data rate than an oscilloscope
2026-02-23T11:28:45 < zyp> anyway, you might want a daq, but I'm not sure that'll be cheaper
2026-02-23T11:31:27 < zyp> google found some cheap shit: https://www.dataq.com/data-acquisition/starter-kits/
2026-02-23T11:34:36 < zyp> but if you only need a single channel, maybe a cheap multimeter with usb, like the xdm1041
2026-02-23T11:54:53 < mawk> ah nice that's cheap
2026-02-23T11:54:54 < mawk> thanks
2026-02-23T11:55:28 < mawk> yeah it doesn't need to be fast, I don't want too much data if I'm going to run it 72h
2026-02-23T11:56:10 < mawk> I'm trying to make an alternative to Otii because bossman doesn't want to buy 3 extra (it's like 1600€/device) for my test setup
2026-02-23T11:56:31 < mawk> I just want to monitor current over time at a couple Hz
2026-02-23T11:56:55 < zyp> for the record: I have an xdm1041 that I'm not overly impressed with
2026-02-23T11:57:21 < mawk> it looks fancy tho
2026-02-23T11:57:28 < zyp> mostly because the ui feels slow, apart from that it seems to work fine
2026-02-23T11:57:50 < zyp> haven't tried the usb functionality, but I expect it'll work as well as every other scpi device
2026-02-23T11:58:04 < mawk> I hope better than riglol
2026-02-23T11:58:16 < mawk> it was a pain to acquire data with their weird protocol
2026-02-23T11:58:29 < mawk> I ended up using the remote UI viewer and making screenshots
2026-02-23T11:58:33 < zyp> a couple of times I regret I didn't get the xdm1241 with built-in battery
2026-02-23T11:58:41 < zyp> when I want to use it somewhere else than my desk
2026-02-23T12:01:06 < zyp> last time I used a scpi device, I ended up with this: https://paste.jvnv.net/view/T8Xop
2026-02-23T12:01:32 < zyp> this is a digital load, not multimeter, but close enough
2026-02-23T12:03:19 < mawk> ah it was a serial port? for the rigol I did it via TCP, but there's also USB
2026-02-23T12:03:42 < zyp> used it to do some accelerated battery testing: https://paste.jvnv.net/view/KTJ2f
2026-02-23T12:04:06 < mawk> ah nice
2026-02-23T12:04:41 < mawk> I'm trying to benchmark the device battery life, so with a power supply and a ammeter in series; the boss didn't buy the license for the otii battery simulator yet

2026-02-23T12:07:10 < zyp> for device battery life, you could also look at the joulescope
2026-02-23T12:08:54 < mawk> I had one at last job
2026-02-23T12:09:06 < mawk> but it doesn't simulate a battery right? it's just measuring
2026-02-23T12:09:12 < zyp> yeah
2026-02-23T12:09:39 < mawk> it's about half the price of the otii
2026-02-23T12:09:55 < mawk> but it's for nanoamps and such, our device is like 10 mA in sleep
2026-02-23T12:09:59 < mawk> so it's a bit overkill
2026-02-23T12:10:07 < zyp> haha, what
2026-02-23T12:10:32 < mawk> yeah the floor is like 3mA, which I observe by keeping the mcu in reset
2026-02-23T12:10:43 < zyp> what kind of device is this?
2026-02-23T12:10:48 < mawk> so the board itself is consuming a lot, and then there's the mcu, it's a F7 so it's not really power efficient
2026-02-23T12:10:57 < mawk> a kind of medical robot
2026-02-23T12:11:07 < mawk> the battery is just as an emergency power supply to last 24h or so
2026-02-23T12:11:30 < zyp> right
2026-02-23T12:12:07 < zyp> the stuff I work with typically has a sleep current on the order of microamps
2026-02-23T12:12:25 < mawk> yeah at my last job it was that too, it was fun; we had a quoted 9 years life on battery
2026-02-23T12:12:34 < mawk> fortunately the devices broke way before we could test that theory
2026-02-23T12:12:34 < zyp> and is also awake rarely enough that the average current is also on the order of microamps or tens of microamps
2026-02-23T12:12:43 < mawk> nice

2026-02-23T12:15:01 < zyp> got the joulescope sitting on my desk right now because I've been working on figuring out how to brick a device

2026-02-23T12:15:22 < mawk> you mean how to reproduce a bricking you found?
2026-02-23T12:33:04 < mawk> I need to order a new javacard, mine is lacking all the good crypto because it's made to be a credit card
2026-02-23T12:33:16 < mawk> so I just turned it into a NFC type 4 tag with 32K of storage

2026-02-23T14:11:09 < zyp> yeah, it's a radio module used in a product we've developed, client reports that devices in the wild are failing because the address becomes all ones
2026-02-23T14:12:18 < zyp> apparently it uses a single flash page to hold all nonvolatile data, because that happens if I cut power while it's writing anything
2026-02-23T14:13:29 < zyp> watching the power consumption on the joulescope is pretty useful for figuring out what the device is doing internally
2026-02-23T14:14:59 < zyp> so far I've found two ways to cause the fault, plus an undocumented command that allows me to write the address so I can fix it

2026-02-23T14:52:16 < mawk> that's unfortunate design
2026-02-23T14:52:36 < mawk> you'd expect stuff like the address to be in OTP or at least in different pages
2026-02-23T14:52:53 < mawk> slap a big cap on its power supply
2026-02-23T15:05:38 < zyp> I don't think it's a supply stability issue, but the supply is switched to keep it off during sleep
2026-02-23T15:06:56 < zyp> so most likely some corner case where the software tries to send a message and then decides not to
2026-02-23T15:08:41 < zyp> maybe if there's a communication glitch and software doesn't get an ack to the send command, it aborts and turns it off

2026-02-23T17:09:37 < qyx> zyp: this is interesting, does it erase the page every time a nvm value is written or is there a bit more intelligent algo?

2026-02-23T21:05:50 < Steffanx> How low level is your stuff mawk?
2026-02-23T21:09:06 < Steffanx> I had to make an app for something and decided to use flutter/dart. It was surprisingly straightforward. But depending on how "low level" your stuff is you still might have to resort to kotlin. And because I was lazy I used a shitload of libraries, but that seems to be the modern workflow anyway.
2026-02-23T21:12:16 < Steffanx> But at least Dart is not Java
2026-02-23T21:27:08 < qyx> sounds like something I should avoid

2026-02-23T21:47:29 < mawk> that's probably possible with flutter
2026-02-23T21:47:54 < mawk> but I can surely mix java and dart right?
2026-02-23T21:48:07 < mawk> I already have the service written, now I need the UI and I'm definitely not writing it in kotlin or java
2026-02-23T21:48:14 < mawk> I was thinking of a webview and doing it in js, somehow
2026-02-23T21:48:14 < Steffanx> Kotlin and dart for sure
2026-02-23T21:48:40 < Steffanx> I used a foreground service in Dart/flutter
2026-02-23T21:49:38 < Steffanx> Some ble and gps stuff that keeps running while the UI does not
2026-02-23T21:50:03 < mawk> oo
2026-02-23T21:50:15 < mawk> yeah same my service stays in the background and pops up everytime a NFC reader is selecting the NDEF application on the phone
2026-02-23T21:50:43 < mawk> then it prompts you to select which app to process it with, if you have several apps registered for the same smartcard application ID

2026-02-24T14:36:42  * Laurenceb_ has a weird issue with bootloaders
2026-02-24T14:37:10 < Laurenceb_> I'm setting a memory address to a magic value in application code, but the address is offset in bootloader code
2026-02-24T14:38:13 < Laurenceb_> application writes 0x20017f9c but value is in 0x20017fd0 according the jtag and bootloader code
2026-02-24T14:38:27 < Laurenceb_> I'll break just after the write in application code to take a look

2026-02-24T14:42:12 < Laurenceb_> ok the fault in in the application code
2026-02-24T14:43:51 < ventyl> make a post about firmware testing off the target hardware -> harvest offended comments
2026-02-24T14:43:55 < ventyl> it works all the time
2026-02-24T14:44:20 < Laurenceb_> ok wtf
2026-02-24T14:44:22 < Laurenceb_>   volatile uint32_t *bootloader_flag = (uint32_t*) ((uint32_t)(&_estack) - BOOTLOADER_FLAG_OFFSET);
2026-02-24T14:44:23 < Laurenceb_>   (*bootloader_flag)=BOOTLOADER_MAGIC_VALUE;
2026-02-24T14:45:02 < Laurenceb_> bootloader_flag is 20017f9c
2026-02-24T14:45:21 < ventyl> is lolrence copying "jump to DFU bootloader" from ST forums?
2026-02-24T14:45:23 < Laurenceb_> which is correct, yet the ram address written is 17fc0
2026-02-24T14:45:27 < Laurenceb_> yes
2026-02-24T14:45:36 < ventyl> thought so, code looks familiar
2026-02-24T14:46:02 < ventyl> IIRc there were some bugs / inconsistencies / fragility in the example code and I had to adjust it
2026-02-24T14:46:17 < Laurenceb_> ok
2026-02-24T14:46:28 < Laurenceb_> but wtf is hppening with my ram
2026-02-24T14:46:29 < zyp> have you tried asking chatgpt?
2026-02-24T14:46:34 < Laurenceb_> lmao
2026-02-24T14:46:54 < ventyl> first of all, this all is probably just a dirty hack, bootloader (at least some of them) was probably never designed to work like this
2026-02-24T14:47:33 < ventyl> Laurenceb_: I'd guess that your startup code is messing with your flag. you have to put it where no .data, .bss, .heap or .stack is
2026-02-24T14:47:34 < Laurenceb_> but I set breakpoint is application code and ram is weird
2026-02-24T14:47:41 < ventyl> otherwise it might get rewritten during boot
2026-02-24T14:47:45 < Laurenceb_> ok
2026-02-24T14:48:30 < Laurenceb_> oh, maybe interrupts are happening
2026-02-24T14:48:32 < ventyl> that DFU is shit BTW, I wouldn't use it for anything more than emergency flash utility

2026-02-24T14:48:44 < Laurenceb_> ok it works sometimes
2026-02-24T14:48:51 < Laurenceb_> I think I know whats wrong
2026-02-24T14:49:14 < Laurenceb_> user code stack is below by magic address
2026-02-24T14:49:32 < Laurenceb_> and there are a lot of usb interrupts, they are screwing with the stack a lot of the time
2026-02-24T14:49:43 < Laurenceb_> this whole method is flawed
2026-02-24T14:50:14 < Laurenceb_> it might work in some cases but I have very heavy usb traffic and there is a lot going on on the stack

2026-02-24T14:50:57 < Laurenceb_> reeee
2026-02-24T14:51:25 < ventyl> which USB stack are you using? ST's own?
2026-02-24T14:51:28 < Laurenceb_> I could offset my stack but thats nasty, I already used the backuyp registers
2026-02-24T14:51:30 < Laurenceb_> yes
2026-02-24T14:51:36 < ventyl> meh
2026-02-24T14:52:01 < Laurenceb_> I could stick something between head and stack, also nasty
2026-02-24T14:52:18 < zyp> how did you pick BOOTLOADER_FLAG_OFFSET?
2026-02-24T14:52:39 < ventyl> it was in forum example snipet I guess :>
2026-02-24T14:52:45 < Laurenceb_> yeah

2026-02-24T14:53:01 < zyp> last time I did something like this, I put the stuff at 0x20000000
2026-02-24T14:53:33 < Laurenceb_> maybe I could use a unused registers lmao
2026-02-24T14:53:51 < zyp> https://github.com/zyp/laks/blob/main/ld_scripts/generated.ld.j2#L45-L47
2026-02-24T14:53:51 < Laurenceb_> like in the crc peripheral there is an unused register, not sure if its reset
2026-02-24T14:54:12 < zyp> .bootinfo always goes into the beginning of ram, before .data and .bss
2026-02-24T14:54:25 < ventyl> I am putting it at fixed place below stacks. But my thing is fully memory protected so I am pretty sure it won't get overwritte
2026-02-24T14:54:27 < Laurenceb_> yeah I want other devs to be able to make application code without custom ld scripts
2026-02-24T14:54:51 < zyp> so it gets a fixed address, I can put whatever there and startup code won't touch it
2026-02-24T14:55:01 < Laurenceb_> do ahb peripherals get reset atnvic_systemreset?
2026-02-24T14:55:12 < zyp> everything does
2026-02-24T14:55:25 < Laurenceb_> not ram, but yeah ok
2026-02-24T14:55:33 < zyp> sysresetreq even pulls the reset pin
2026-02-24T14:55:45 < zyp> duh, everything *with* a reset
2026-02-24T14:55:58 < Laurenceb_> ok
2026-02-24T14:56:07 < zyp> with the exception of debug infrastructure, you wouldn't want that to get reset
2026-02-24T14:56:45 < zyp> < Laurenceb_> yeah I want other devs to be able to make application code without custom ld scripts
2026-02-24T14:57:20 < zyp> > I wanna store some shit somewhere in ram, but I'm not gonna tell anybody where, so I just have to hope nobody will touch it
2026-02-24T14:57:29 < Laurenceb_> lol
2026-02-24T14:57:43 < zyp> that's literally what you're doing
2026-02-24T14:57:50 < Laurenceb_> I'll try 10k offset and see if it works
2026-02-24T14:58:15 < zyp> it'll work until it doesn't
2026-02-24T14:58:22 < Laurenceb_> wait I have a plan
2026-02-24T14:58:35 < Laurenceb_> disable all interrupts in the user jump code
2026-02-24T15:00:46 < ventyl> jesus Lolrence, just get a bigger crowbar
2026-02-24T15:00:57 < ventyl> or fuck crowbar, get hammer instead
2026-02-24T15:10:07 < Laurenceb_> yeah that fixes the problem, but SWV printf hardfaulted on me :S
2026-02-24T15:12:40 < Laurenceb_> think it was due to shutting down/restarting debugging in weird order, bit owrrying
2026-02-24T15:13:36 < Laurenceb_>   extern uint32_t _estack;
2026-02-24T15:13:37 < Laurenceb_>   volatile uint32_t *bootloader_flag = (uint32_t*) ((uint32_t)(&_estack) - BOOTLOADER_FLAG_OFFSET);

2026-02-24T15:19:23 < ventyl> if your hack mitigated one problem but created another, I wouldn't call it a fix
2026-02-24T15:19:41 < Laurenceb_> I think the SWV is unrelated, my code seems to wokr
2026-02-24T15:19:56 < ventyl> lolrence, you are running fast to hack that stuff out of your way rather doing things properly
2026-02-24T15:19:59 < ventyl> where I have seen that?

2026-02-26T12:01:02 < karlp> heh, as part of the corp merger, we've moved to a new 365/teams tenant, and they've "migrated" all histories over.
2026-02-26T12:01:36 < qyx> date is current, 2024
2026-02-26T12:01:45 < karlp> so that means, that the channels were created on the new tenant, with a single message posted to them, named "history-yyyymmdd.html" which is then a scrollable html view of the old messages.
2026-02-26T12:01:57 < qyx> lol
2026-02-26T12:02:03 < karlp> like, ok, better than "we're not migrating" i guess...
2026-02-26T12:02:14 < karlp> also, now I get to smack my team again.
2026-02-26T12:02:39 < karlp> I complained ages ago that they were doing all "team" chat in an overuused meeting group chat, not a proper "team"
2026-02-26T12:02:44 < karlp> so... none of that got migrated.
2026-02-26T12:03:21 < karlp> I complained when I joined that I had no history fo the team, and I've been trying to post everything in the formal "team" chat instead, but no....
2026-02-26T12:03:28 < karlp> anyway, great to be back in corpo land!

2026-02-26T12:23:05 < qyx> anyway, gonna use 5x 22u ceramic instead of <1mR tantalum
2026-02-26T12:26:01 < qyx> haha capacitance at 5 V is 13 uF
2026-02-26T12:28:04 < qyx> 22u/25V/1210 murata has 19 uF at 5 V
2026-02-26T12:29:18 < qyx> tantalum polymer 100u/10V is 7 eur in singles O_o
2026-02-26T12:30:49 < qyx> classic solid tantalum is 0.60 :S
2026-02-26T13:03:21 < c10ud> nice

2026-02-26T16:22:20 < mercenary> always have been. however, even with all the modern tech, when anything majorly breaks on the interwebs the back-channel to get hold of someone at a large CDN or ISP is still IRC
2026-02-26T16:23:34 < ventyl> yeah, in the event of major catastrophy event, the tech savvy remaining of civilization will probably get together on some forgotten BBS or something like that
2026-02-26T17:17:26 < Steffanx> I don't remember I had any breaking issue with Teams the last year(s). It used to, but not anymore. How up to date is your experience ventyl ?

2026-02-27T12:07:59 < qyx> I need any IC to sacrifice as a template
2026-02-27T12:08:44 < zyp> flash, typically?
2026-02-27T12:09:11 < qyx> flash is not square
2026-02-27T12:09:36 < qyx> MIC5801YV is the cheapest I was able to find
2026-02-27T12:11:49 < qyx> haha ATF22LV10C-10JU PLD is even cheaper
2026-02-27T12:11:58 < zyp> was about to suggest that :p
2026-02-27T12:12:03 < zyp> https://www.digikey.com/en/products/detail/microchip-technology/ATF22V10CQ-15JU/1914509
2026-02-27T12:13:54 < qyx> oh but this one is 4.3 mm high
2026-02-27T12:14:01 < qyx> my gyro is 5.4 mm high :S
2026-02-27T12:17:04 < Steffanx> What gyro comes in that package?
2026-02-27T12:18:37 < karlp> expensive ones...
2026-02-27T12:19:24 < Steffanx> That for sure, but that is not specific enough 
2026-02-27T12:19:31 < jpa-> 4.3 mm seems like the standard PLCC28 height, so you probably find 5.4 mm only in special stuff
2026-02-27T12:45:57 < karlp> just glue some cardboard on top...
2026-02-27T12:46:18 < karlp> bonus, you can even ink it, and see if you sqush anything...
2026-02-27T12:50:02 < zyp> how about just 3d printing a model?
2026-02-27T13:10:49 < karlp> pretty hard to test soldering it, though not sure why that would be super important...
2026-02-27T13:11:02 < karlp> ok, xmc i2c reading worked second try. nice.
2026-02-27T13:11:22 < karlp> I pre-emptively wired up test probes to sda7scl and turned out I probably didn't really need that...
2026-02-27T13:12:08 < zyp> that's why it just worked
2026-02-27T13:20:38 < qyx> Steffanx: gypro4300

2026-02-27T13:21:51 < qyx> jpa-: yeah it is that ceramic-gold space package
2026-02-27T13:28:20 < jpa-> ask the manufacturer if they have any broken ones for soldering process validation :)
2026-02-27T13:29:44 < qyx> haha
2026-02-27T13:34:06 < karlp> lol sensiron: https://bin.jvnv.net/file/kKP2H.png
2026-02-27T13:34:10 < karlp> zyp: lol
2026-02-27T13:37:28 < karlp> also lol sensiron, temp/humi sensors use crc8 with poly 0x31 and init 0xff, liquid sensors use poly 0x31 and init 0.
2026-02-27T13:41:10 < karlp> sensiron are wild, they ~all have 32bit serial numbers, at totalyl random locations for different parts.
2026-02-27T13:41:20 < qyx> this gyro is the same, "under no circumstances write calibration data more than 5 times during the product life"
2026-02-27T13:41:22 < karlp> and it's always specified in a separate document, not the device datasheet.
2026-02-27T13:42:21 < qyx> also "this value is written in OTP, you cannot write it again, yes you have to change it after reset if the OTP one is not correct"
2026-02-27T13:43:05 < qyx> then "this value can be written once and is saved in OTP, you cannot modify the OTP value afterwards"
2026-02-27T13:43:31 < qyx> "oh yes you can indeed set it but will be reloaded after reset"
2026-02-27T13:43:51 < qyx> I wonder who even makes such abominations

2026-02-27T15:09:10 < c10ud> i think it could probably be due something about eastern europe 
2026-02-27T15:09:50 < c10ud> but holy crap, it was avail in the thousands
2026-02-27T15:10:17 < zyp> «thousands» is not a lot
2026-02-27T15:10:51 < zyp> a single reel of components can contain «thousands»
2026-02-27T15:11:10 < c10ud> well in case it goes through i would only need about a hundred per year

2026-02-27T15:11:43 < c10ud> honestly when i see a component > 1000 on some distributor i think it's 'common'
2026-02-27T15:14:48 < qyx> it depends and you deeky needs to track multiple distributors
2026-02-27T15:14:58 < qyx> also, inertial sensors are volatile
2026-02-27T15:15:19 < qyx> you can buy bmi088 devboards and desokplder to test
2026-02-27T15:15:46 < qyx> 10000+ pcs are expected in may, not that bad, sounds like a shortage
2026-02-27T15:16:00 < qyx> s/deeky/definitely
2026-02-27T15:16:31 < c10ud> yup, they were expected mid march just a couple wks ago
2026-02-27T15:16:43 < c10ud> anyway, lesson learned
2026-02-27T15:17:03 < qyx> I failed multiple times with inertiak
2026-02-27T15:17:24 < qyx> I would buy sensors first before boards are made
2026-02-27T15:18:32 < c10ud> covid period all over again 
2026-02-27T15:28:35 < Steffanx> Someone bought all 6000+ of them half January...
2026-02-27T16:01:43 < mawk> it was Steffanx

2026-02-27T17:39:17 < mawk> I ordered a FIDO2 card with desfire application to play with
2026-02-27T17:39:33 < mawk> but when aliexpress wakes up from their chinese new year alcoholic coma I will get proper javacards I can program myself
2026-02-27T17:39:37 < mawk> then I can have some backup
2026-02-27T17:39:58 < mawk> with a CTAP to HID bridge I can use the NFC FIDO2 card as a key to login to website
2026-02-27T17:40:03 < mawk> so nobody will steal my pornhub account
2026-02-27T18:00:49 < Steffanx> Lol no mawk. I just checked octopart
2026-02-27T18:03:26 < karlp> hrm, now I'm rapidly breaking i2c, what a surprise.
2026-02-27T18:03:33 < karlp> not catching naks properly and resetting.

2026-02-27T19:37:32 < karlp> well, fuck this sensiron periodic measurements then.
2026-02-27T19:37:55 < karlp> you set a rate, but if you ever read it too fast, it tosses the data, and even if you then wait longer than the rate, it never seems to recover ever again.
2026-02-27T19:38:03 < karlp> I mean, not without sending a break7restart.
2026-02-27T19:38:42 < karlp> I tried setting it to 4 hz, and then polling at 220ms + jittered time to see  what would happen, and if you get a nack, even if you wait 500ms before retrying, it's... just not there anymore.
2026-02-27T19:38:44 < karlp> silly shit.
2026-02-27T19:39:03 < karlp> we don't have alert pin configured anyway, so might as well just do one shot mode and not care about the rate then.

2026-02-27T22:42:31 < mawk> I'm making an android app

2026-02-27T22:42:54 < bitmask> nice, whats it do
2026-02-27T22:49:22 < mawk> it's a NFC tag emulator
2026-02-27T22:49:25 < mawk> to emulate a NFC type 4 tag with any contents you want
2026-02-27T23:10:59 < karlp> qyx: that's the plan, yeah, just do single shot periodically. seems far more reliable.
2026-02-27T23:11:09 < karlp> I'd kinda expected to just get the last reading or something, but no...
2026-02-27T23:11:29 < karlp> anyway, mostly seem to have it stable for the _known_ error cases :)
