The problem is “linux” - which one?!

As far as I’ve been able to figure out, these boards have not been propagated into mainline linux. So if you are saying FBSD draws from mainline linux then you might not be getting the good stuff.

There is friendlyarm’s distribution /boot/sun50i-h5-nanopi-neo2.dtb that decompiled doesn’t look remotely like anything I’ve seen elsewhere. There is https://linux-sunxi.org/Main_Page <https://linux-sunxi.org/Main_Page>. There is armbian - some sun50i-h5-i2c*.dts overlays here: https://github.com/armbian/sunxi-DT-overlays/tree/master/sun50i-h5 <https://github.com/armbian/sunxi-DT-overlays/tree/master/sun50i-h5>. Given the moving target of what FDT is, who knows whether these are remotely useful.

Bottom line is we non-experts have next to zero chance getting these boards working for us with FBSD.
