Hello @0xFF, I have the same issue as you, last working image for me is Armbian_21.08.1_Rockpi-s_bullseye_current_5.10.60_minimal.img.xz
All newer images could not boot, and UART is silent.
As a workaround I flashed and booted that version and then just did :
apt update && apt upgrade
then the new version Armbian 22.11.4 Bullseye with Linux 5.15.89-rockchip64 booted up without any issue.
