LVDS resolution not applied for AUO G150XAN02.0 panel on mba8mpxl-ras314 (i.MX8MP) – Need help to solve issue

[Embed Square]

Hello Armbian team,

I am working with the TQ mba8mpxl-ras314 (i.MX8MP) board and trying to use an LVDS display: AUO G150XAN02.0 (1024×768).

I have built Armbian from source using:

./compile.sh build \
  BOARD=mba8mpxl-ras314 \
  BRANCH=current \
  RELEASE=jammy \
  BUILD_DESKTOP=yes \
  BUILD_MINIMAL=no \
  DESKTOP_ENVIRONMENT=xfce \
  DESKTOP_ENVIRONMENT_CONFIG_NAME=config_base \
  KERNEL_CONFIGURE=no

I created a custom LVDS DTS overlay with the correct timing from the display datasheet (65 MHz pixel clock, 1024×768, proper porch and sync settings), and added it to

 

However, after booting the image, the LVDS output still stays at 1280×800, which is the default panel configuration for the Tianma panel used in TQ’s reference device tree.

The expected resolution 1024×768 does not apply, even though:

The overlay compiles correctly

The .dtbo file is present

The build finishes successfully

I am unsure whether:

My overlay is not being applied

The correct panel node name is different from &display

Another overlay overrides mine

The i.MX8MP LVDS binding needs a different structure

Armbian’s mba8mpxl-ras314 base DTS is overriding the timing

maybe @schmiedelm has an idea?
