New BPI user here. 
Anybody have any suggestions on what Image to put on an M3 or does anybody know what the best one to use is?
I have an orange pi with Armbian. I like Armbian. So far I have tried Ubuntu 18.0.4 and Raspbian stretch on the M3. With Ubuntu I couldn’t get the filesystem to expand to the whole ssd card. So I installed Raspbian. Today I tried to upgrade from Stretch to bullseye and encountered dependency issues Now I am looking to use another image.
There is no official support for M3 but images are here https://github.com/armbian/community and you can always build whatever variant.
I ended up putting Raspbian stretch back on it but if anybody uses a different image that is better please let me know.
Also, is their a stable image for Raspbian bullseye that anybody knows of?
Armbian is a lot better even without official support. This only means you are on your own - without help of Armbian staff (unless you need commercial support). As you are on your own in case of Raspbian too.
