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?
