The problem is =E2=80=9Clinux=E2=80=9D - which one?! As far as I=E2=80=99ve 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=E2=80=99s distribution = /boot/sun50i-h5-nanopi-neo2.dtb that decompiled doesn=E2=80=99t look = remotely like anything I=E2=80=99ve 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.
