Check error code for UART4

[LeeJaewon]

We made a new board with STM32MP157FAC1.
I tried booting with SD card with STM32MP1 Starter Package image of STM32MP157x-EV1.
I am inquiring about the following error.

Can you guess what error it is?

Hi @LeeJaewon ,

Except if your board is stricly same as EV1 it's normal this is not working.

You might adapt your Device Tree to you hardware. 

You can refer to FAQ: STM32MP1 - How to create a device tree adapted to your design with STM32CubeMX? 

Hope it help
