I connected the Waveshare 4.3 inch DSI display to the BeagleY-AI DSI0 port and updated and edited the two overlays that I found on BY-AI and RPi repos to get it working. I compile to dtbo files and add to extlinux.conf file.
But the display only lights up little while booting. No images.
I’m trying to follow this issue on openbeagle.org but I didn’t succeed.
I would appreciate any help.
(I realize this screen use “chipone, icn6211” for DSI-RGB bridge.)
These are some log:
