Hello,

I am trying to interface the LCD RGB 720x720 with Luckfox Pico Ultra W.

I am following the steps as given here on the wiki page

https://wiki.luckfox.com/Luckfox-Pico/L ... RGB-Screen
When I try to run the lvgl (Graphic Lib) demo, I get the following error.

cannot open /dev/dri/card0
: No such file or directory
I am using the OS (Linux) prebuilt image from the Official Luckfox Google drive.

If I run the luckfox-config command and goto RGB section it is disabled by default and if try to enable it, it asks for some parameters which are blank. This step is not mentioned in the Wiki page.

Sorry for the trouble, finally got it working!

I ran luckfox-config command and then enabled RGB and Touch Peripherals. In RGB peripheral I put panel configuration parameters and timming parameters from the Wiki device tree settings.
After restarting the board, the entry for DRI was created /dev/dri in rootfs. Then I ran the LVGL demo and woo! It ran successfully.
