08:34 <re_irc> <korken89> You are welcome to give RTIC a look, and come join us in the RTIC room :) I think we are the most proc-macro heavy DSL in the embedded space as we do a lot of schedulability analysis based on a task/resource model. Website: rtic.rs

12:00 <re_irc> <dkhayes117> James Munns: what kind of media are looking for regarding the WG Twitter final Friday showcase? Pics, Gif, blog post?

12:01 <re_irc> <James Munns> Really anything! Probably a "what is this" sentence or three, plus a link or pic or something :)

14:20 <re_irc> <dkhayes117> Propane float gauge with hall effect sensor to read position. Servo driven for consistent positional testing. nrf9160 for LTE-M running embassy 😀

14:20 <re_irc> <dkhayes117> https://psion.agg.io/_matrix/media/r0/download/matrix.org/CmskrheFGcsbhxxvfIHwxAen/ezgif-3-2a4111409b.gif

14:22 <re_irc> <diondokter> Cool! Once I get this working your LTE-M can be async as well :D

14:22 <re_irc> https://github.com/diondokter/nrf-modem

14:22 <re_irc> <dkhayes117> That's awesome!

14:26 <re_irc> <James Munns> dkhayes117: Should I treat this as a Friday submission? :D

14:27 <re_irc> <dkhayes117> Yes, I DM'd it to you on Twitter as well

14:27 <re_irc> <James Munns> Oh, perfect, thanks :D

14:27 <re_irc> <James Munns> I'm gunna schedule all those tweets tonight. I think I have 5 or so, so far? Definitely still time if anyone else wants to show anything off :)

15:30 <cr1901> adamgreig: How's the bridge working now?

15:31 <re_irc> <adamgreig> I see you!

15:31 <re_irc> <adamgreig> I nuked the whole homeserver database and restarted it, so all the ghost users should be gone

15:31 <re_irc> <adamgreig> hopefully it was a remnant of something updating and won't reoccur

15:33 <cr1901> Beautiful... the other ~50 users thank you for your efforts

15:33 <cr1901> (incl me :P)

19:17 <re_irc> <boondocker> found I have unaligned RISCV jumps. Is there a trick to get them aligned?

19:18 <re_irc> <boondocker> linker script has

19:18 <re_irc> . = ALIGN(4);

19:18 <re_irc> .text : {

19:18 <re_irc> ... long message truncated: https://psion.agg.io/_matrix/media/r0/download/psion.agg.io/057d7b2e4686dd21d7beefc45d0f001e70ad2268a4eb894a888c733f3ffe2f5c (8 lines)

19:18 <re_irc> _text_start = .;

19:20 <re_irc> <boondocker> interestingly it worked fine using riscv32i, but aligned with riscv32imac

19:20 <re_irc> <boondocker> * unaligned

19:27 <re_irc> <boondocker> +Ahh, that it explains it. It seems the C (compression) extension changes the alignment to 16 bit

20:09 <re_irc> <thebutlah> does defmt _need_ rtt? I don't know if that exists on RISCV processors

20:12 <re_irc> <dirbaio> it bundles its own rtt impl, and yes it works on riscv

20:13 <re_irc> <jannic> It doesn't need rtt, but it needs a "global_logger". Rtt is one way to provide that. https://defmt.ferrous-systems.com/setup.html#global_logger

20:13 <re_irc> But as dirbaio already wrote, rtt works on riscv.

20:19 <re_irc> <thebutlah> does rtt not need hardware support? I'm a bit confused how it works

20:19 <re_irc> <thebutlah> is it that the "log" is simply stored in memory and you expect that a hardware debugger will be able to look at that memory while the program runs to read the logs?

20:20 <re_irc> <dirbaio> rtt is just a spec for a way to lay out a ringbuffer in RAM

20:21 <re_irc> <dirbaio> so yes, all you need is a way for the debugger to read RAM

20:21 <re_irc> <dirbaio> * read/write

20:21 <re_irc> <dirbaio> in ARM it'd be SWD/JTAG, in RISCV it's most likey JTAG (I guess?)

23:09 <re_irc> <therealprof> PSA: I learned earlier today that there's a new kid in town to output assembly/LLVM-IR/MIR for any executable via cargo plugin: https://crates.io/crates/cargo-show-asm which seems to take over for the somewhat outdated https://crates.io/crates/cargo-asm and happens to work a lot better in addition to having more features, especially for embedded binaries.
