I will look into this over the weekend (running ptests is a new area for me). I'm curious what images you usually use / recommend?
I've usually just used this one core-image-minimal from openembedded-core and used oe-init-build-env for the environment and manually added meta-openembedded/meta-python into bblayers.conf.
I see core-image-ptest exists and looks like a better choice than core-image-minimal
Thanks for the feedback by the way, I really appreciate it.
