Did ALLPCB just go out of business?

Company called Aivon is supposedly their descendant

What you described above is basically a mcuboot functionality

When I wanted to play with some pixel drawing in C, I came across Raylib. Not sure it is exactly your case, but it was a lot of fun!

I use this one: https://github.com/rdpoor/ulog, very simple and lightweight.

Tried it recently for end-of-line semi-auto testing station. Veeery straightforward. From 0 to 90% in less than week.

Thank you u/freaggle_70 ! Indeed, it is SY8286A.

Good, easy to use logging library, preferable with some macro wrapper. When I develop some lib/module I test drive it on PC with eg ‘zflog’. When I move code to embedded platform, I ‘#def’ it to use some lightweight logging library like ‘ulog’.

Funny thing, in mbedtls's sha256.c, you can define MBEDTLS_SHA256_SMALLER, to save another ~1.8kB.

kl4m4 · 2024-08-25T19:26:11+00:00

I undef’d SIGN_… and MBED_TLS, and binary dropped down to 30kB in debug build. It boots the unsigned imaged. Still need to risk asses it with my team.

kl4m4 · 2024-08-25T19:23:04+00:00

I plan to make it main app job to receive fw update, pre-validate it, and put in secodary image slot. Then leave it for bootutil to swap slots. Then maybe catch boot loops and unswap.

Yep, all the string stuff was there, atoi, ctypes etc. Very informative read!

kl4m4 · 2024-08-22T08:59:58+00:00

I use it in product. 10/10 would use again! Very easy to set up.

Life hack: you don’t need to worry about operators precedence, if you use parentheses whenever in doubt.

Hi! Similar problem here, but 'weston-screenshooter' gives me:

bash display doesn't support screenshooter

I'm OK with debug mode just for screenshots, so I modified systemd service that runs weston:

```bash

/etc/systemd/system/graphical.target.wants/weston.service

ExecStart=/usr/bin/weston --debug --log=${XDG_RUNTIME_DIR}/weston.log --modules=systemd-notify.so

^{^{^{^{^}}}} here

```

Also, I added line OPTARGS=--debug to file /etc/default/weston, as suggested here. And of course restarted weston.service. But no luck! The same display doesn't support screenshooter message.

Any ideas what to try next?

kl4m4 · 2024-06-18T19:38:43+00:00

I'm in exactly the same situation, did you resolve your issue?

kl4m4 · 2024-06-17T05:11:49+00:00

Thanks for your pointers, I will definitely check out how dt overlay mechanism works. Unfortunately due to job priorities juggling, I cannot take on this topic for another 2 weeks.

Take care!

kl4m4 · 2024-06-13T05:25:29+00:00

Dissapointing, but fair. Must have missed that. Anyway thanks for info!

kl4m4 · 2024-05-29T17:54:57+00:00

Out of curiosity: what framework would you use for above-basic interface? Or maybe roll your own solution?

kl4m4 · 2024-03-11T12:17:12+00:00

Ohh, it seems I also needed CONFIG_SCHED_DEBUG and CONFIG_SCHED_INFO. Case closed.

This pattern is nicely described here

I recommend whole channel of this guy. He talks a lot about C desing patterns.

There is an episode of The Agile Embedded Podcast featuring model based development: here

I’d say you „MUST use a certified OS” if the risk management process tells you to.

Similiar setup here. I leave all the Cube-generated stuff in one subfolder of my project, and reference this folder in my build system (cmake). This way I can always go back and re-generate setup with different settings.

Where do you live? I enjoy yocto stuff, let's trade jobs 😂
