Hi Zhilei,

Besides the info Anton provided that the tech forum is a good place to get closer to the project, this doc introduces the code structure: https://tf-m-user-guide.trustedfirmware.org/docs/technical_references/design...

And it describes:

cmsis_psa/* - CMSIS implementation for PSA-FF-M SPM. cmsis_func/* - The library model implementation.

And I admit some of the docs especially the technical ones are out of date, we are under an technical document updating procedure now: https://lists.trustedfirmware.org/archives/list/tf-m@lists.trustedfirmware.o...

Welcome to tell us what kinds of docs you are expecting and we will put them into the update proposals and discuss how to address them.

BR.

/Ken

Dear All, I view the tf-m source code for the first time, and many of the code details can not be make clear. So .., where may I find the design documents of spm, for example: trusted-firmware-m-TF-Mv1.5.0\secure_fw\spm\cmsis_func and cmsis_psa software modules.
