Hi!
I was looking forward to running my graphical application on the renegade, but now that I’m trying to start the computer, there is no HDMI output at all. I have followed the instructions, and this is the UART trace that I get:

As you can see, there are multiple “failed to probe rk hdmi” uboot messages and finally “no video mode” errors from GRUB. Other than that, the board seems to be working fine, but sadly no video output makes it useless in my case. This particular run was done with the debian-12-gnome-arm64+roc-rk3328-cc.img, although I guess the particual image makes no difference. Do you have any advice that could help? Or is it true then that the boards have hardware issues regarding HDMI? I have two of them, and will test the other one tomorrow.
