Hi Andrey,

The problem seems to be related to the TF-A version.
If I use the older imx_5.4.47_2.2.0 TF-A then the sha256 calculation via CAAM does not fail.
I just tried the imx8mp_evk and with CONFIG_IMX_HAB=y the board does not pass the SPL.
I used the upstream TF-A for my build, without HAB support enabled the board boots:

When HAB in enabled, the only thing that can be observed in the console is:

My understanding, at least for the i.MX8MM case, is that mainline TF-A does not support HAB, so the NXP TF-A should be used if HAB support is required.
Please check: https://lists.trustedfirmware.org/archives/list/tf-a@lists.trustedfirmware.o...
Thanks for the hint!
That would be understandable, but I would at least be expecting to have some error messages. But I do not get any - the board just does not pass SPL at all, as like SEC0 hangs during RNG instantiation (my rough speculations here).
Does the board boot with IMX_HAB=y with NXP TF-A?
Nope, unfortunately also not. Once HAB config is enabled on the i.MX8MP - the board does not pass the SPL, even with NXP TF-A.
Regards,
Fabio Estevam
