CubeMX Project for BRK

[Akshay]

Hi Team,

I have modified the the minimal config project in CubeMX and generated the device trees for the kernel,uboot and TF-A. How do I compile these files and add it to the developer package so that it works on the BRK board.

Akshay,

The procedure to compile custom device trees with the Developer Package is shown here: https://wiki.st.com/stm32mpu/wiki/How_to_compile_the_device_tree_with_the_Developer_Package/.

Thanks @Neeraj Dantu.
The compilation was successful.But when I flash the U-Boot from my cubemx project the BRK board doesn’t seem to boot up. If i use the device tree for u-boot from the link:
https://github.com/octavosystems/OSD32MP1-BRK-device-tree/tree/master/u-boot-v2020.01 the board seems to boot fine. Is it ok if i use this u-boot file along with my custom kernel device tree?

Akshay,

That should work as long as you have all the features you need in U-Boot. Please check the SD card detect declaration in CubeMX generated device tree and make sure that it is the same pin as the CD pin connected in the BRK schematics. I suspect this is preventing the board boot.

Best,

Neeraj
