I just added ROCK64 to our image build script and generated new images. It's still (latest) Armbian kernel and U-Boot packages, but freshly partitioned image file + rootfs via debootstrap. Probably the more recent U-Boot works more reliable: https://dietpi.com/downloads/images/testing/
If the Bullseye image does not boot, the Bookworm one won't either, which differs only in userland.
EDIT: Ah I just saw now that you were able to SSH into the system with the old image, but no HDMI output? Also finishing first run setup, including kernel upgrade does not help with this?
EDIT2: Ah lol, here it was reported at Armbian: https://forum.armbian.com/topic/24146-th...lled-hdmi/
Do you see the same error(s) in dmesg -l emerg,alert,crit,err?
