Hello, i've been working with buildroot and raspberry pi CM4 IO board. I have been able to fully compile the system and get the system to boot to graphical GUI within 5 seconds which has been exciting! The issue I've been facing is the device only works through HDMI. I have been trying to get it to work through the DISP1 port.
This set up works without any issues with Raspbian Lite OS. If I remove my buildroot SD Card and pop in a Raspbian Lite SD card it instantly boots up to console using the DISP1 port. The buildroot SD card boots up while attached to HDMI though.
I have added the appropriate dtoverlay=vc4-kms-v3d as well as dtoverlay =vc4-kms-dsi-7inch to the config file.
Am I missing a particular menuconfig option for the DSI option or something that. I have searched up and down with no avail. I have the gallium V3D and VC4 drivers added in menuconfig.
