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.

But U-boot doesn't start.

Has anyone had this problem before? any suggestions?

As we discussed over email and as you mentioned the upgrade to the latest u-boot-at91_2022.10.bb, U-Boot was able to start after OP-TEE. I'm closing this issue.
