00:36 <RockBoynton[m]> defmt question: I am getting WARN defmt_decoder::log::format: logger format contains timestamp but no timestamp implementation was provided; consider removing the timestamp ({t}or{T}) from the logger format or provide a defmt::timestamp! implementation even though I definitely use the defmt:timestamp! macro, am I missing something?

00:53 <swork[m]> <JamesMunns[m]> "If it's a plain zero initialized..." <- And in fact I did. Thank you.

01:12 <gregormoritz[m]> ivmarkov: dirbaio thanks for your help! I built a c++ project using esp-idf v5.2.2 and solved c binding issue of rust functions

01:25 <gregormoritz[m]> * ivmarkov: dirbaio mheld thanks for

07:06 <thejpster[m]> <RockBoynton[m]> "defmt question: I am getting ..." <- Which version of defmt and which version of probe-rs?

11:43 <thejpster[m]> does anyone know of a nice tool to merge two ELF files, with non-overlapping segments?

11:47 <thejpster[m]> I guess I could convert them to .hex and merge them with srecord tools

11:47 <diondokter[m]> thejpster[m]: Merging hexes is what we did before (when we had to)

11:48 <thejpster[m]> maybe llvm-objcopy can do it

11:49 <diondokter[m]> I don't know of a tool that can do it. Maybe objcopy yeah.

11:49 <diondokter[m]> Using the `object` crate, it shouldn't be that hard to create a simple tool yourself. (If you don't care about debug info)

11:54 <Kaspar[m]> I think the linkers (gnu ld, lld, ...) can also do it, with a slim custom linker file. there's syntax for including binaries at specific addresses.

12:02 <JamesMunns[m]> <diondokter[m]> "Merging hexes is what we did..." <- Yeah, elfs -> hex, merge hex, hex -> bin is what I've done before as well. Or compile one, make it a bin, then `include_bytes!` into a `link_section`'d static (careful, you need to make it an array and not a slice)

12:48 <thejpster[m]> I'm trying not to include_bytes! the second firmware, otherwise doing a cargo run replaces it.

12:48 <thejpster[m]> (but that is what I have done before)

12:48 <thejpster[m]> I'd like to be able to cargo run either of them individually (flashing the ELF with probe-rs) and then have a combo image for people who aren't debugging

12:49 <thejpster[m]> I can live with the combo image being a UF2 and not an ELF.

12:49 <diondokter[m]> Hmmm, yeah then probably merge hexes and then convert to UF2

12:59 <diondokter[m]> I asked björn3 and he also didn't know a tool for this

13:42 <thejpster[m]> Can I just concatenate an ihex or do I need to parse it? I used to know the various header bytes off the top of my head.

13:43 <diondokter[m]> No, you can't just concatenate generally

13:44 <diondokter[m]> We used to use the nordic utility: https://docs.nordicsemi.com/bundle/ug_nrf_cltools/page/UG/cltools/nrf_mergehex.html

14:17 <thejpster[m]> this one seems to be written in Python: https://github.com/sifive/riscv-zephyr/blob/master/scripts/mergehex.py

14:17 <thejpster[m]> which uses https://pypi.org/project/intelhex/

14:17 <dirbaio[m]> yeah that's the nordic one

14:19 <dirbaio[m]> * yeah that's the nordic one huh that also has Nordic copyright but seems more cut-down than the nrf5x tools one

14:30 <thejpster[m]> in renesas news:

14:30 <thejpster[m]> it has configuration data located in flash. I didn't carve out those bytes, so there is program code at that those locations.

14:31 <thejpster[m]> I might be able to look at what I flashed, and work out what I've accidentally set those configuration values to. I guess you're supposed to ... put a carve out in the linker script somehow? Start your code at 0x0810, and just put the reset vector at 0x0000 and hope it isn't more than 0x400 bytes in length?

14:32 <dirbaio[m]> that's such a weird design, especially seeing they already have some separate"configuration area" lol

14:34 <diondokter[m]> lol

14:34 <diondokter[m]> Did you get the board at embedded-world? Because I've got the same one lying around

15:26 <thejpster[m]> no I paid for it with my own actual money, because I needed to make it to the free shipping level at Digikey
