IMX8M plus Dual display on Linux 6.6.52

[SanthoshRajavel]

HDMI and LVDS are enabled on the i.MX8M Plus EVK. LVDS displays the GUI correctly, while HDMI currently shows only the Linux TTY console. The requirement is to display two different GUI contents simultaneously—one on HDMI and another on LVDS—by freeing HDMI from the framebuffer console and enabling DRM/Wayland-based multi-display support.

Hello,

You could use the following:

=> U-Boot > setenv displayinfo 'video=mxcfb1:dev=ldb video=mxcfb0:dev=hdmi,1920x1080
M@60,if=RGB24' for LVDS and HDMI dual displays

Best regards/Saludos,
Aldo.
