meta-lxatac

meta-lxatac is a set of OpenEmbedded/Yocto build recipes maintained by Linux Automation GmbH for the LXA TAC (Test Automation Controller). It builds the device's software images and RAUC update bundles, and is intended both for installing official releases and for creating customized, pre-configured images for your own infrastructure. The README covers installing official stable or testing bundles directly with rauc, building the image as-is with bitbake, and two approaches to maintaining a custom layer: placing it inside the meta-lxatac tree or using meta-lxatac as a git submodule. It also explains how to generate and use your own RAUC signing keys, add custom recipes such as deploying SSH public keys, and set up a private bundle update server. For recovery, the project documents flashing the device over USB using DFU and fastboot, including entering USB boot mode on the STM32MP1-based hardware and troubleshooting boot issues.
