@jock THAT WORKED!!! I have no idea why, or how, but that worked. Thanks for all the help. Do you think I'll have any problems in the future when updating the OS?

@alexc Thanks for your patch and suggestions. It turns out the DRM heap isn't strictly required for DisplayPort Alt mode, but I'm sure it resolved other issues within the 6.6 kernel. I assumed it was the DRM heap because it was the only missing kernel configuration option. I suppose the kernel doesn't report missing source code drivers, or I simply didn't notice. It’s great to have your help getting this Armbian BSP build function. At least until a mainline version is released

There's an Armbian provided SystemD service named armbian-led-state with the following description: # Armbian led state save and restore # Stores the current led state at shutdown and restores # it during bootstrap Maybe that's it? If so, you could disable it if it bothers you? Or adjust the script it calls at /usr/lib/armbian/armbian-led-state-save.sh?

All things are possible. The question is who's interested in doing (or funding) the work, and if technical data is available to do it. The build system is at https://github.com/armbian/build. If you know how to build a kernel, device tree, and bootloader, you can define how to do those steps there.

Bookworm. But my point was the version 35.1 is what got installed when I ran the scripts in the first post. If the script installed 37 for you because you're on Ubuntu then I probably am on the wrong track. Yes I believe it does this. I was just pointing out that drm_prime works for me but I guess that could just be due to different hardware on the device. I'm not using an Orange Pi.
