Hi, i have tried Ubuntu22.04-LTS today followed the instructions as given in https://github.com/Joshua-Riek/ubuntu-rockchip/wiki/Ubuntu-22.04-LTS to enable 8inch radxa display, display is not working, even backlight is not there.
path to *.dtbo file is not correct in the above wiki page, i have changed it still it is not working. Am i missing anything, with same display connections i have changed SD card that is loaded with ubuntu22.04 old version by JR, added overlay file in ubuntuEnv.txt and it is working without touch functionality.
