question: has it started a DSI display of the requested resolution - said BOE is 1200x1920pixels - when you VNC into your Pi?..
I ran dtdebug on and saw this:Code:
006356.382: dtdebug: Opened overlay file 'overlays/vc4-kms-dsi-dumb-panel-pi5.dtbo'006356.484: dterror: not a valid FDT - err -9
If yes it did what it should. You have been told that it's not a good idea to start DSI without proper termination. I've just showed to you how to achieve what you've asked for.
As this is an uncommon use case I need to say that i don't care about if there is an error in the logs....
Will check my logs to see if I see such a message , but never spotted one when doing this s** .
You're not trying to start your own u-boot?
