Thanks for that. I'm not sure I understand yet if meta-raspberrypi and meta-debian can be used together, I'd have thought they are both at the same layer and so couldn't be. And it seems to be based on Jessie. I did read about how to add APT by specifying: CORE_IMAGE_EXTRA_INSTALL += "apt" but how on earth does it know what you've 'baked' into your recipe? Otherwise surely it'd basically install the system again when handling the user's package's dependencies. Wouldn't it? Perhaps https://community.nxp.com/thread/325384#comment-486697 https://community.nxp.com/thread/325384#comment-486697 is the answer, which sounds like a bit of work. I also found this which looks kind of interesting: https://elinux.org/images/c/c6/Smart_r002.pdf https://elinux.org/images/c/c6/Smart_r002.pdf and https://community.nxp.com/docs/DOC-328199 https://community.nxp.com/docs/DOC-328199.
