Compute Module • Display-HDMI - Hotspot!

Hi All,

I am having a RPI CM4 https://www.raspberrypi.com/products/co ... -io-board/ Board and WaveShare WS170120 Touch display and working with Yocto Kirkstone Sato image , I want to enable hdmi hotplug feature into board, I have enabled hdmi_force_hotplug = 1 and hdmi_drive = 2 in /boot/config.txt, but still this is not working, on https://www.raspberrypi.com/documentati ... ation.html , I am finding "pin_defines

This section is used to set specific VideoCore functionality to particular pins. This enables the user to move the camera power enable pin to somewhere different, or move the HDMI hotplug position: these are things that Linux does not control. Please refer to the example DTS file below." when searched for hdmi hotplug..

but it will be applicable for RPICM4 Board or not I am not aware, can any one user from RPI Engineer help here to make hdmi hotplug work on RPI CM4 board by providing exact steps or suggestions on what are all changes needed at dts level or somewhere else ?

Thanks
Ankur
