Hi Matheus

The image at

https://people.freebsd.org/~sos/ARM64/current-RK356X-images/nano5-sdcard.img.gz

for the Nanopi R5S does indeed boot with both HDMI output and serial console (1500000baud).

The boot loader (EDK2 in FDT mode) is very picky on SD card quality though from experience, I works for me with Sandisk Ultra / Extreme cards but not with Samsung and cheap noname SD cards YMMV.

You can build a stock ARM64 generic kernel and most things will be usable, however as Ganbold wrote the DTS files is not in there yet (and not even in linux where our DTS files are fetched from).
However the EDK2 boot loader provided (and used in above image) on 

https://people.freebsd.org/~sos/ARM64/EDK2-RK356X/NANOPI-R5S_EFI.itb	
NANOPI-R5S_EFI

does hand over the “right” DTB file if you want to experiment.

If you need the used DTS file and build guidance let me know in private mail...
