Hello,
i´ve got the same problem here. Non off the bullseye images in the archive will boot (no blue light) except of: https://armbian.lv.auroradev.org/archive/odroidn2/archive/Armbian_21.08.1_Odroidn2_bullseye_current_5.10.60.img.xz
after update&upgrade there is no ethernet and black screen so i can´t use it anymore. Bookworm and jammy works fine, but i need openmediavault so i need bullseye.
Any ideas?
Sorry for my english. Best wishes
