Hello all,

I purchased a few NanoPi Fire3 [1] boards and would love to run
FreeBSD on them. I see that there are u-boot packages for a number of
NanoPi boards, but Fire3 is not included. The CPU involved is "Samsung
S5P6818 octa-core ARM Cortex-A53".

How would I go about decoding the necessary partitions and sizes to
get this running? I found this repository [2] that contains some
scripts, but I am unable to decode the required details. I am happy to
experiment a bit to get this running, and we could create the
resulting package as well.

Many thanks in advance,
Daniel
