    Hi Hui,

    The Secure Storage is provided through the OPTEE OS. TI uses the same services as supported in the public OPTEE. The current TI Processor SDKs use 3.12 version of OPTEE OS, and use the REE FS for Secure Storage at present. I recommend you to look through the Secure Storage documentation of OPTEE:

    optee.readthedocs.io/.../secure_storage.html

    eMMC RPMB support using device unique key is not yet formally supported in current released TI Processor SDKs, we have very recently had some patches accepted to upstream OPTEE.

    regards
