rauc-hawkbit-updater v1.0 Released
Back in 2018, rauc-hawkbit-updater was started by Prevas A/S as a C/GLib port of our rauc-hawkbit Python prototype (also called RAUC hawkBit Client) that was mainly developed for showcases and to serve as a demonstration and evaluation platform for others.
rauc-hawkbit-updater instead is explicitly developed with real-world use cases in mind. Just as its earlier Python counterpart, it operates on the target as an interface between RAUC, the embedded Linux update framework, and hawkBit, an OTA roll-out backend framework.
RAUC interfacing with hawkBit: Components overview
Since its first incarnation in 2018, rauc-hawkbit-updater's code was refactored, bugs were fixed, and features were added. With the addition of a test suite that was capable of performing interaction tests with actual hawkBit test instances, the project got more mature and, with the beginning of 2020, rauc-hawkbit-updater was finally moved to the RAUC GitHub organization under the maintenance of Lasse Klok Mikkelsen (Prevas A/S).
Now, more than a year later after more refactoring, stabilization and initial documentation, we're very happy to announce the first release version: rauc-hawkbit-updater 1.0!
Up Next
We won't stop here. A whole bunch of feature pull requests are already queued up, i.e.:
- HTTP retry handling
- Resuming interrupted downloads
- Support for action cancellation
So if you are interested in managing your embedded system's updates with RAUC and hawkBit, make sure to check it out.
Wonder How To Get Started?
- Set up a hawkBit instance (e.g. via docker)
- Set up RAUC for your target
- Cross compile rauc-hawkbit-updater for your target (a Yocto recipe for this is available in meta-rauc)
- Provide a configuration file that points to your rauc-hawkbit-updater instance
- Start the rauc-hawkbit-updater daemon on your target to let it authenticate and poll for updates
For more details follow our Quickstart guide and the documentation. You're invited to join the community, discuss and contribute! Either via matrix channel #rauc or on GitHub Issues, Pull requests or Discussions.
rauc-hawkbit-updater initially identifies with hawkBit (debug mode).
Finally, we would like to thank the folks from Prevas A/S for starting this project and making it open source under LGPL-2.1, and especially to Prevas' Lasse Klok Mikkelsen, the lead maintainer until the v1.0 release. Starting with v1.0, the project will now be primarily maintained by the Pengutronix developers Bastian Krause and Enrico Jörns.

Showcase: Fail-Safe (OTA) Field Updating
Being able to robustly and securely update embedded systems and IoT devices in the field is a key requirement of every product today. The update framework RAUC is the basis for a modern and future-proof solution. In this showcase we present the basic principles of a fail-safe update system and how Pengutronix can support you with implement this for your platform.
Bridging the Gap: The RAUC hawkBit Client
OTA field updates are a common requirement in modern embedded device deployments. The larger the amount of devices to control, the more important is having a good infrastructure that is reliable in updating and smart in rolling out the software.
RAUC v1.11 Released
Ho Ho ho! As the year's progress bar approaches 99%, another update is already completed: RAUC v1.11 is here!
RAUC v1.10 Released
Just in time for the EOSS 2023 in Prague, we have released v1.10 of RAUC. Just-in-time means the release was actually finalized by Jan Lübbe in the train to Prague (like I finally wrote the majority of this blog post on the train back).
RAUC v1.9 Released
"Getting things off the ground" could be the motto for the v1.9 release of RAUC. The support for custom metadata in the manifest got a step further, a new, more flexible, D-Bus API for bundle inspection paved the way for obtaining more detailed information, and a new manifest hash marks the first of several planned changes for configurable event logging. However, one of the most invasive changes happened under the hood: We have started the transition from autotools to meson as a build system.
