Arne worked on the balena-os/balena-kontron-mx8mm repository, focusing on integrating a new bootloader into the board support package using BitBake and Shell within the Yocto Project ecosystem. He updated the build system by adding the meta-ked-bootloader layer and refreshing build configurations to ensure seamless bootloader discovery and usage. Arne also aligned the project’s meta-openembedded and poky submodules with the latest kirkstone upstream commits, maintaining compatibility with recent components. His work demonstrated depth in embedded Linux and build systems, delivering a bootloader-enabled BSP that improved release readiness and ensured the project remained up to date with upstream developments.
