I have followed these steps:
Enable “Application Configuration > Graphics Support > Light and Versatile
Graphics Library (LVGL)”
Enable “LVGL > Enable Framebuffer Port”
Browse into “LVGL > LVGL Configuration”
In “Color Settings”
Set Color Depth to “32: ARGB8888”
In “Memory settings”
Set Size of Memory to 64
In “HAL Settings”
Set Default Dots Per Inch to 250
In “Demos”
Enable “Show Some Widgets”
Enable “Application Configuration > Examples > LVGL Demo”
I encountered the issue while trying to test the LVGL demos on the Raspberry
Pi 4B.
