How to create custom board for the STM32MP

[robin_elecgator]

I have followed this guide, https://wiki.st.com/stm32mpu/wiki/How_to_create_your_own_machine but that doesn't work well and requires a lot of manual changing to get the image booting. (it breaks extlinux stuff)

My custom board is too different as one that are supported by DK or EV devkits.

What is the best way of adding my board to yocto? I don't seem to find a tutorial or guide about this.

Hi @robin_elecgator​ 

Indeed there's no complete tutorial probably because it was a bit complex to cover each and every possible use case.

I'm afraid you can not avoid manual change to fit with your hardware.

In order I can try to help you to progress, can you please futher details steps you have followed :

Did you generate Device Tree with CubeMX ?

Did you already success to boot your custom board with modified boot chain ( TF-A, U-boot ) ?

Can you please further details issue you have with extlinux  ?
