Hello,

How to create a new image for BPI-M3 any how to document? I tried https://github.com/freebsd/crochet/tree/master/board/BananaPi-M3 however RGB lights are always red, can see ethernet port becoming green however can’t see it’s taking any IP.

If I want to build a new Linux or FreeBSD image what is the process?

Thanks.
