I have a custom board based on RK3568jq.
I made Linux minimal image using Yocto:
Everything works fine, but current configuration is HDMI.
I have a question:
How can i add LVDS display to my minimal Linux OS build for rk3568jq using Yocto system ?
What dts file should i change and how ?
I did it before but not for Yocto, i used stardard FireFly compile Linux firmware system:
sudo ./build.sh itx-3568q-lvds-ubuntu.mk
sudo ./build.sh
I made changes in file
