Hi,
I have rock 5+. When I install the debian image I can use the display port on usb type c. Everythings is okay.
The dipslay port doesnt work on Android image. I have to found this situation.
I checked
cat /sys/class/drm/card0-DP1/status
Although I plug the cable I always see disconnected.
Maybe hpd pin not configured in the device tree.
Can you help me for resolve this stuation?
