Check or update before upgrade!
- On your board, edit the file
/boot/armbianEnv.txt: Find the linefdtfile="rockchip/rk3588-nanopc-cm3588-nas.dtb"and replace this line withfdtfile="rockchip/rk3588-friendlyelec-cm3588-nas.dtb", DO NOT REBOOT YET - Update your kernel as usual.
You only have to do this once, and only on existing installations. New installations and further update will not need any manual intervention.
(video instructions were not done by Armbian team, but it might help you get going)
If you are having a NanoPi R6C variant, replace fdtfile=rockchip/rk3588s-nanopi-r6s.dtb in /boot/armbianEnv.txt with fdtfile=rockchip/rk3588s-nanopi-r6c.dtb
