Yocto/OpenEmbedded

Course description

The Yocto/OpenEmbedded course gives you the basics to create your own embedded Linux distribution, with an up-to-date Linux kernel and a complete and customised root filesystem filled with proprietary and open source packages. We will go through the OpenEmbedded build system (which is the core of the Yocto project), discussing the central components such as layers, recipes, classes and configurations. We go through the build process step by step and explain how to add new packages, create custom root filesystem images and debug the build process.

The course is based on practical exercises where participants learn and explore the build process while creating their own customised layers, package recipes and images.

The course is normally given in Swedish but courses in English are available on request. All course material is in English. Linux computers and course targets (Beaglebone black) to perform the exercises are available to all participants. Participants can keep their Beaglebones after the end of the course.
