Enable LVDS panel on STM32MP257F-EV1 based on Android OS

[Tim_ho]

Dear ST Developer Support,

I want to enable LVDS panel on STM32MP257F-EV1 based on Android OS.

I tried to modify device tree stm32mp257f-ev1.dts and stm32mp257f-ev1-overlay.dts to enable LVDS panel.

But I could not enable it. When I revert the device fdt file, I saw that the LVDS related device tree nodes 

• lvds

• ltdc

• panel-lvds

• panel-lvds-backlight

• display-controller

status were "disabled".

In stm32mp257f-ev1.dts and stm32mp257f-ev1-overlay.dts file, the LVDS related device note are status="okay".

So, I confuse on this problem. Maybe somewhere dts overlay this device node, but I cannot find it.

Would you help me solve this problem?

Thanks.

Hi,

by default the LVDS panel is activated in our Android Package, you don't have to modify the device tree (stm32mp257f-ev1-overlay.dts)

If you don't have any display on LVDS screen , please check again documentation ( connection ?, ...)
