When attempting to attach the screen mentioned in the subject, I’m running into problems. The backlight doesn’t activate, and /dev/fb0 just writes to the VGA output.
I’m not seeing anything in the kernel event logs indicating that the device is even detected, though I could be looking in the wrong place.
I get no additional entries in /dev nor /dev/input (so no touch events nor video output). Is there some jumper fiddling I need to do? An additional kernel module I need to build? A device tree entry that isn’t in the default evaluation board’s device tree? All the hardware is Toradex reference implementation stuff purchased directly from the Toradex web site, so you know everything about the environment.
The kernel, u-boot, and device tree are all from the Colibri iMX7d Toradex image.
