TF-A v2.6-r1 kernel hang issue?

[milkylainen]

I have a custom build on the stm32mp157f dk2.

stm TF-A v2.6-r1 or vanilla TF-A v2.7, using sp_min.

stm U-boot 2020.10-r2 or vanilla Barebox-2022.06.

I've also tried U-boot 2021.10-r1, but that one crashes the kernel even earlier.

Kernel: vanilla 5.18/vanilla 5.19.

FSBL starts fine.

Both v2.6 and v2.7 starts just fine. sp_min too.

Both TF-A versions load and executes BL33 (stm u-boot or vanilla barebox) just fine.

But when I use stm TF-A v2.6 kernel crashes when started from BL33.

Works fine with vanilla TF-A 2.7 all other components being equal.

I can see the kernel decompression but stops executing directly after that.

This happens regardless if I do the fip manually or if TF-A puts it together.

Kernel 5.18 or 5.19 doesn't matter. But when I use vanilla TF-A both kernels boot.

TF-A is configured exactly the same using the variable configuration.

Hi @milkylainen​ ,

Sorry to come late in the thread.

First do you still have issue or did you manage to fix it by yourself ?

Thanks,

Olivier

Hi Olivier.

Np. I am still having this issue.

I have a hard time mixing parts of the ecosystem with vanilla.

So the only configuration I have gotten to a working userland is

vanilla tf-a 2.7, stm u-boot 2020.10, vanilla kernel 5.18+.

If I go to stm tf-a 2.6-r1, kernel crashes.
