Compute Module • Re: CM5 trouble with 7inch display on DSI

@6by9: can you please confirm below is correct understanding:

When using CAM/DISP0 interface (silkscreen label J5) below has to be added to config.txt

Code:

dtoverlay=vc4-kms-dsi-ili9881-7inch,dsi0
When using CAM/DISP1 interface (silkscreen label J16) the jumpers on J6 need to be mounted and below has to be added to config.txt

Code:

dtoverlay=vc4-kms-dsi-ili9881-7inch
Confusion may come from the fact that J6 on CM4IO has to be mounted when using CAM/DISP0 but now is required for CAM/DISP1.
That is my understanding, yes.
I have tried all those with both DSI0 and DSI1 as well as V1 and V2 of the screen and I wasn’t successful. The screens work fine with the RPI5. I have updated the OS, all possible updates. And I’m running a clean install. Any ideas?
