  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.
