MIPI display blank after enabling uart8

I'm using a custom stm32mp157a board with a DSI display.

If I enable uart8 using pins J8 (UART8_TX) and J9 (UART8_RX) the display driver (panel-sitronix-st7701.c) doesnt load properly and the display stays blank.

uart8 does work properly. If I disable uart8 the display works again.

Hello @Rc.1​ ,

Please can you share your complete boot log and your dtb file used.

Does the problem occurs only in Linux or directly from the boot?

Best Regards,

Kevin
