STM32MP157x: Secure Boot authentication failed

[AZaki.2]

hello I have build tf-a and u-boot and signed them as specified in the st wiki documentation:

But I get the following error when booting up:

NOTICE: CPU: STM32MP157FAC Rev.Z

Note: I didn't deploy the publicKeysHashes.bin on my board since I'm using test keys (I's one time operation non revesible)

Is it required publicKeysHashes deployemnt required ?

[AZaki.2]

I deployed hash keys to otp and don't get the error anymore.

STM32 MPUs Boot Rom are enforcing the hash verification even the Secure Boot is not enforced which is different from other vendors such as NXP and Xilinx....

Not really great !!
