I don't usually have anything to contribute, but I notice= d something that might make an easy fix for someone that knows a little more= than me. On my RPi4 (4 gig model), the Pi3 images for 12.2-RELEASE and STABLE don't h= ave HDMI out, except for the EFI boot screen which disappears quickly. These= images also are supposed to use DHCP, but they never connect to the network= , so maybe it doesn't actually boot at all. Guess I need a serial connector t= o find out. However, 13.0-CURRENT boots fine. I hoped to avoid CURRENT, though as I'm wa= nting to use the Pi in production. In desperation, I decided to try a hack, which I didn't really expect to wor= k. I flashed 12.2-STABLE, then erased the boot directory and copied the 13.0= -CURRENT boot directory files to the card. Then 12.2-STABLE could boot and s= how HDMI, but only up to a handoff to the kernel, which crashed. (Which is w= hat I expected.) But the fact that the HDMI was working was a surprise. So, could I Frankenstein 12.2 and CURRENT to work? Maybe even just by copyin= g a file? Though I can handle custom compiling if needed. Attached is my DMESG, though I've been messing with the system so it's not c= ompletely stock. --Matt PS. You may also notice it only sees 900 Meg of memory on a 4 gig model. I'm= not sure what's going on there, but I noticed a similar problem was encount= ered and fixed on Linux: https://github.com/home-assistant/operating-system/= issues/439
