Thank you for taking the time to try and make this work!
I tried running the image from your github on two of my Orange Pi 5 Pros, and unfortunately all I get is a solid white LED without any progress even after ~2-3 min. Joshua's 6.1 Ubuntu works fine. Any idea on what I need to do to make the Orange Pi 5 Pro boot with your image / build? Happy to help debug or enable you to make progress. Vulkan on an RK3588 board would be amazing!
