How do I create the STM32MP157AAA custom board Device Tree via CubeMx?

[DLee.15]

Hello

I'm going to create and flash my custom board with CubeMx. But I don't know how to modify the dtb file.

Can you give me a link or a way to get the right help?

Hi @DLee.15​ 

Thanks for your post and welcome in the MP1 Community,

Do you know our wiki online documentation ? https://wiki.st.com/stm32mpu/wiki/Main_Page

I invite you to have a look.

eg For device tree purpose :

"But I don't know how to modify the dtb file." I suppose you mean dts since dtb is the compiled format ? :smiling_face_with_smiling_eyes:

I'm quite sure also that following article might give you some interesting hints :

Hope it help
