I am not sure if cboot will read and use device tree from bootloader-dtb partition. I checked the cboot source code, did not find code to read that partition. Does anyone know if cboot use DT data in bootloader-dtb partition?

Yes, cboot uses the DT in the bootloader-dtb partition.

You can just get a arbitrary driver which would read DT properties to test.

But I can’t find the code in cboot to read DT from bootloader-dtb partition.
I can find the code to read CBO and kernel dtb partition in cboot.

Have you found it to move your issue forward? Any result can be shared? Thanks

I did find find cboot code read bootloader-dtb partition, but it seems it uses other way to read the dtb data.
