STM32MP151CAA and some issue with SECURE-BOOT

[gianlucarenzi]

Hello everyone!

I am trying to bring up a custom board based with a STM32MP151 (C Variant) with OPTEE, TF-A and U-BOOT.

So far so good, but when running the FIT Image (Kernel + DTB) it fails finding the boot storage. It looks like the device-tree is not correctly parsed, because I did not find any activated/bind drivers in the kernel log dmesg during boot.

Here is the bootlog (from OPTEE/TF-A/UBOOT/FIT)

If the filesystem is corrupted, it might prevent the kernel from mounting it. Check the filesystem integrity and potentially try to reformat and reinstall the root filesystem.

[gianlucarenzi]

The filesystem is good. The kernel does not find any blockdevice (nor any other driver mentioned in the device-tree blob).

In the meanwhile I have just found a little issue: in the kernel config CONFIG_OPTEE was missing. There was only CONFIG_TEE=y.

Now with the newest kernel here is the logs: (basically they differs with some more optee messages)

Any other help? Here are my device-trees for kernel and the device-tree for scmi stuff...
