AM625-Q1: TTE Secure storage

Hi Expert,

The secure storage in TEE is secure RAM or other ROM just like emmc? if it is secure RAM, does it mean we do not have a non-volatile storage area. What should we do if customer need the SOC application key? do they need external storage just like TA100?

Biao,

Not sure if I understand the question. The secure storage media can be either volatile(RAM) or non-volatile(Flash, EMMC etc) depending on the application use case. For example, if the secured blob needs to be stored across the power cycle you need non-volatile memory.

Please let us know the use case.

Thanks

Yogesh
