To help be get started I followed these slides, http://events17.linuxfoundation.org/sites/events/files/slides/ELC-2017-isar.pdf Unfortunately this configuration raised some errors related to the dpkg.bbclass. After some digging around, I noticed that there is a branch named custom-kernel in you git repo. In this branch the dpkg.bbclass is different from the master one. Which approach should I use if I want to build a custom kernel from the sources? Thanks Frank.
