While major changes are about to come, the RAUC v1.6 release already paves the way under the hood. Built-in streaming support will be one of the next features built on top of the 'verity' bundle format in RAUC.
Did you know? Initializing CAN interfaces with systemd-networkd
End of January systemd 250 was added to Debian bullseye backports. With a lots of new features and fixes now comes the possibility to set the timing of CAN bus interfaces with systemd-networkd. In this blogpost I will take a look at why this helps us maintain our embedded Linux labs.
Tutorial: Evaluating RAUC on QEMU - A Quick Setup With Yocto
RAUC is an update framework for safely deploying verified updates on your embedded Linux devices. It ensures atomicity of the update process to protect from sudden power outages, hardware failures, etc. So, why would one like to run RAUC on an emulated platform?
Wir haben doch etwas zu verbergen: Schlüssel mit OP-TEE verschlüsseln
Moderne Linux Systeme müssen häufig zwecks Authentifizierung bei einer Cloud- basierten Infrastruktur oder einer On-Premise Maschine eigene kryptografische Schlüssel speichern. Statt der Verwendung eines Trusted Platform Modules (TPM), bieten moderne ARM Prozessoren die TrustZone-Technologie an, auf deren Basis ebenfalls Schlüssel oder andere Geheimnisse gespeichert werden können. Dieses Paper zeigt die Nutzung des Open Portable Trusted Execution Environments (OP- TEE) mit der Standardkonformen PKCS#11 Schnittstellen und i.MX6 Prozessoren von NXP als Beispiel.

QM meets CI
