Hey Robert, I’m working on a custom board and have everything up and going but since it’s much more simple than the BBB I think I can cut out a lot of what is in your Ubuntu 20.04 image. I’m just starting to research how to get a smaller rootfs up and going. I tried a vanilla Ubuntu Base 20.04 and that seems to be way too sparse.
Before I get to far I wanted to see if you had any advice on the best path forward? I don’t need things like cape managers, graphics, etc… I have my kernel whittled way down, I just need the rootfs to match.
EDIT: I have 256MB for RAM so it would be nice to be able to get a rootfs less than that so I can tftp it to the eMMC without having to increase the DDR size, not sure if that’s feasible?
