Download v0.3 release of RAUC

The RAUC team is proud to announce that we've just released RAUC v0.3! Again, we have worked a lot on stability and support for more and more use cases. RAUC now supports pure UEFI-based booting on x86, multiple board variants in the same bundle, intermediate certificates and enhanced feedback from the boot selection layer.

Enhancements

  • Added support for intermediate certificates, improved bundle resigning and certificate information for hooks. This makes it easier to use a multi-level PKI with separate intermediate certificates for development and releases.
  • Added support for image variants, which allow creating a single bundle which supports multiple hardware variants by selecting the matching image from a set contained in the bundle.
  • Added support for redundant booting by using EFI boot entries directly.
  • Added boot information to rauc status
  • Added rauc extract command to extract bundles
  • Support detection of the booted slot by using the UUID= and PARTUUID= kernel options.
  • Improved the status and error output
  • Improved internal error cause propagation

Bug Fixes

  • Fixed boot slot detection for root=<symlink> boot parameters (such as root=/dev/disk/by-path/pci-0000:00:17.0-ata-1-part1)
  • Removed redundant image checksum verification during installation.

Testing

  • Improve robustness and test coverage
  • Use gcc-7 for testing

Documentation

  • Added documentation for intermediate certificates, re-signing bundles, image variants and UEFI support

RAUC v1.15 Released

Enrico Jörns | | RAUC

It’s been over half a year since the RAUC v1.14 release, and in that time a number of minor and major improvements have piled up. The most notable change in v1.15 is the newly added support for explicit image types, making handling of image filename extensions way more flexible. Other highlights include improved support for A/B/C updates and several smaller quality improvements. This release also includes the final preparations for upcoming features such as multiple signer support and built-in polling.

RAUC - 10 Years of Updating 🎂

10 years ago, almost a decade before the Cyber-Resilliance-Act (CRA) enforced updates as a strict requirement for most embedded systems, Pengutronix started RAUC as a versatile platform for embedded Linux Over-The-Air (and Not-So-Over-The-Air) updates.
