Hello, I'm an optee newbie, I'm trying to integrate optee-os in Microchip SAMA5D2. I built optee-os with yocto, but seems that AT91bootstrap stuck when it tryies to start optee.

` RomBOOT Backup mode enabled

Has anyone had this problem before? any suggestions?

It seems that the code is stuck at optee-os. It would be better to give the board info and the version/configuration of the code generated for reproducing the issue.
