Hi all,

The PSA Firmware Update API specification is now published on Arm Developer.

This document introduces a standard firmware interface for installing firmware updates.

The document can be downloaded from https://developer.arm.com/documentation/ihi0093/0000/

This is an initial BETA release in order to enable wider review and feedback. We shall release new Beta versions to address feedback and comments.

Sherry Zhang in TF-M has begun an implementation of this interface, which is a work in progress.

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

Regards, Adrian
