FreeBSD on Nanopi R4S(E)

Hello,

I amd trying to install FreeBSD 14.1 on this arm64 board and, despite
booting fine till the booting process needs to mount the root partition.
It just finds none. I am using sd card on it, but tried also having a copy
on the USB stick. I finds none, and the boot process won't continue.

Have anyone done this? I know there are images for FreeBSD 13.x for it,
but I cannot find any clues so far on how to make it boot.

I am using the guide on

thanks in advance,

matheus
