#rauc — Public Fediverse posts

📣 RAUC & labgrid community meetup at #embeddedworld 2024 in Nürnberg.

📅 Date: Wednesday, April 10th
🕒 Time: 14:30 - 15:30
📍 Location: Cafe in Hall 4, located at 4-640a

Join us for a casual gathering to talk about these open-source projects. It's a good opportunity to meet fellow developers and users in the #labgrid & #RAUC communities, exchange ideas, and discuss future directions.

No need to RSVP—just come by if you're interested. See you at #ew24!

I just released version 0.2.0 of #caterpillar, my little application, wrapping around #rauc for system updates on e.g. embedded platforms using attached media.

The application now exposes its own #dbus interface, which can be used for interactive workflows. The non-interactive use-case on first start is still the default (but can be turned off).

The documentation has been extended as well, to describe these new features.

I created a tool for automatically discovering and installing #RAUC update bundles from attached block devices: https://crates.io/crates/caterpillar

I just released 0.1.0 as a first version with a very small set of features, but I'm really glad it is finally out there!

Big thanks go out to #nonlinearlabs for being so patient with this project and funding the work!

Dug my way into a deep rabbithole last night, while working on an A/B update system based on #RAUC .
Turns out #efibootmgr 18 changed its default output to be more verbose and broke the assumptions made by #RAUC

Patching up a C codebase was not on my list of things for last night, but alas, here we are:

I've released #golang #rauc go-rauc library version v0.2.1, with support for writing custom pre and post install handlers, as well as for the handler-to-rauc messaging protocol.

Yep, turns out you currently can't sign #rauc update bundles with ed25519 keys, but the error message is quite misleading imho. No mention of unsupported key algorithms only a vague mention of "mismatched keys". With RSA4096 keys everything suddenly works as expected.

Hmm, is it possible that #rauc doesn't support ed25519 for signing update bundles and I have to recreate my whole CA for update signing with RSA? #linuxembedded #linux

Hmm, #rauc seems really great, but there seems to be not much open source stuff around to actually identify updated bundles on a remote server. Might need to build a small tool checking github (gitea) releases for compatible updates #embedded #linux

Finally got #rauc based updates working on my #craftbeerpi firmware. Now doing some quality of life improvements for users and then I will probably try to create something which can feed GitHub-Releases to rauc, essentially using GitHub as an update server for my #buildroot based firmware.

And back to #rauc and #uboot .

Let's get a custom build done today!

Today hacking on disk image creation for use with #uboot and #rauc again.

The workflow is a bit time consuming, so I'm starting to split work into smaller tasks...
