Official RPi 7" touchscreen not working with v11.4.0 and CM4IO
I'm new to Emteria and have just installed v11.4.0 on a CM4 attached to the CM4IO board. The official RPI DSI display does not display anything, but an HDMI monitor works ok. Should the DSI display just work or do I need to change any configuration settings? Also, could someone confirm how the DSI display should be connected to the CM4IO board.

Hi @mb_mtrl ,
you need the appropriate device tree overlay, e.g.: https://datasheets.raspberrypi.com/cmio/dt-blob-disp1-only.bin
Put this file as dt-blob.bin on the /boot partition.
A more thorough tutorial is here: https://www.raspberrypi.com/documentation/computers/compute-module.html
but the device tree overlay is the only thing you need to adjust with emteria.OS
