Can you elaborate more on your requirement.

DRA821 has once crypto accelerator which is in the MCU domain. On HS devices this is consumed by the TIFS in order to support secure boot.

Along with this we do have A72 core's which support arm trustzone extension defined by ARM.

I only got " The hardware-based trust anchor must support at least 2 privilege levels." from our customer, do you think DRA821 can meet this requirement?

Thanks

Max

Hi Max,

Can you elaborate more on your usecase what you are looking for, what do you mean by 2  privilege levels?
