I finally got it running. I had painted my self in to a corner, so I started over from scratch, and now my layer can build a bootable image based on packagegroup-ros-comm
but please forgive a ROS/bitbake novice - still one thing I don't understand though: I made a little test ROS package ( based on beginner_tutorial ) I pushed it to a git repository. It builds fine and is deployed to the target, but if I make a change and push that to the git repo, this change is not reflected on target, how do I force bitbake to checkout the head, and rebuild my package ? - I thought *bitbake -c clean recipe && bitbake recipe * would do the trick.
