Hi all,

The PSA Firmware Framework for M 1.1 Extensions specification is now published on Arm Developer.

This document introduces a set of updates and extensions to the Arm® Platform Security Architecture Firmware Framework (FF-M) specification, designed to build on the capabilities provided in version 1.0.

This is an initial ALPHA release in order to enable wider review and feedback on the changes proposed to be included in the v1.1 specification. At this quality level, the changes and interfaces defined are not stable enough for product development. When the proposed extensions are sufficiently stable to be classed as Beta, they will be integrated into the FF-M version 1.1 specification.

The 1.1 Extensions document can be downloaded from:

https://developer.arm.com/documentation/aes0039/latest

Both the 1.0 Specification and the 1.1 Extensions document are linked from the main PSA architecture page:

Ken and I have presented a number of times at last year's Tech Forums on the proposals in the specification, most recently I provided a summary of the whole document on 10th December 2020.

If you have any feedback, please provide it to arm.psa-feedback@arm.com, or discuss the proposals here in the TF-M mailing list.

Regards, Andrew
