So, no one has any suggestions on what I should be seeing or how to poke linux about where it is breaking down? Like, I said, I haven't played with DSI interfaces before. Does anyone have the output I should be expecting in dmesg? What are the correct modules to load?
I was digging around and it looks like the Pi finds a device for DSI but Im not seeing anything connected to it. This is from the Pi that does NOT have the panel connected:
But the system with the panel connected looks basically identical:
The second paste is from the Pi5 with the display attached, the first is from the cm5 without the display. Im looking for troubleshooting tips. Suggestions on where to begin looking to decide if this is a system configuration issue or a hardware failure.
Any ideas?
