Yocto and bitbake are my go-to tools for developing for Raspberry PI and BeagleBone (and NextThing Co C.H.I.P. and ChipPro before they died.) I'm working on a 'meta-planetcom' meta layer (similar to meta-rpi for the raspberry pi family) that will allow me to build compete Debian distros and images for this little machine.
Are there any other developers also working on this? I would like to avoid needless duplication of effort if possible.
