Tried Armbian 5.05 and here are some issues I found.
1. The auto mount of USB drive is not working.
2. The eject or umount of USB drive is not working.
3. The HW decode of video using MPV is not working. B.t.w., the MPV preinstalled is old which is 0.6.6 while the newest is 0.14.
4. The Mali400 driver seems to work, but no libmali.so and libEGL.so in /usr/lib.
5. Booting takes a long time even after configured the board type and created user account. Booting time is way slower than the 3.4.39 kernel. It will pause about a minute to boot after pressing reboot.
