Thanks Milan,


I tried the dtc method - using this example from the man page:


dtc -@ -O dtb -I dts -o device_overlay.dtbo device_overlay.dts


Actual command used: dtc -@ -O dtb -I dts -o sun50i-a64-uart2.dtbo=20
sun50i-a64-uart2.dtso



then copied the resulting dtbo file into the /boot/dtb/overlays=20
directory, and added the entry into=C2=A0 /boot/loader.conf then rebooted=
.=20
The result was nothing happened :-( no uart2 in the dmesg log at all and=20
no extra ttyu(x) either


I've just also attempted: /usr/src/sys/tools/fdt/make_dtbo.sh=20
/usr/src/sys /usr/src/sys/dts/arm64/overlays/sun50i-a64-uart2.dtso /tmp


then copied the .dtbo file into /boot/dtb/overlays and rebooted. Again=20
nothing??


Maybe there is a difference between 12-RELEASE and 13-CURRENT?


Regards,


Kaya
