LVDS not working with STM32MP257F-DK board

Hi,

When testing the stm32mp2-openstlinux-6.6-yocto-scarthgap-mpu-v24.12.05 image, the LVDS screen doesn't work and blocks the board's startup (in u-boot) and I can't reset the board unless I disconnect the LVDS port.

On the other hand, the HDMI is functional, and the screen works without any problem on my STM32MP257F-EV1 board.

Note that the board is powered via a USB port capable of delivering up to 1.5A.

Thank you
