I have no idea what causes the crap characters in the diff below, they
should be blanks. Looks like a problem with the mailing list software.
Trying another type:
/* Set Main Stack Pointer limit */
- extern uint32_t Image$$ARM_LIB_STACK_MSP$$ZI$$Base;
- __set_MSPLIM((uint32_t)&Image$$ARM_LIB_STACK_MSP$$ZI$$Base);
+ REGION_DECLARE(Image$$, ARM_LIB_STACK_MSP, $$ZI$$Base);
+ __set_MSPLIM((uint32_t)®ION_NAME(Image$$, ARM_LIB_STACK_MSP,
+ $$ZI$$Base));

With the integration of the IAR toolchain support in TF-M it has become
important to use the REGION_DECLARE/REGION_NAME macros in
platform/region.h instead of using symbols like
"Image$$ARM_LIB_STACK_MSP$$ZI$$Base".
The IAR linker can not use these symbols and the macros in combination
with the IAR specific cmake rules creates appropriate symbols for all
the supported toolchains.
Example diff:
---
/* Set Main Stack Pointer limit */
- extern uint32_t Image$$ARM_LIB_STACK_MSP$$ZI$$Base;
- __set_MSPLIM((uint32_t)&Image$$ARM_LIB_STACK_MSP$$ZI$$Base);

I see that there has been some progress in the source code to further remove the overhead of TFM_NS_CLIENT_IDENTIFICATION when the option is disabled.
However, I still don't understand the user view of that feature. How should I use it, also considering the fact that my application may get updated during lifetime.

Hi Reinhard
I think the closer to a high level documentation is this page:
https://ci.trustedfirmware.org/job/tf-m-build-test-nightly/lastSuccessfulBu…
To your question regarding the nv counters, they are currently used by MCUBOOT and Protected Storage Service. You may be interested in this patch under review which is will expose them as a service

Subject: [TF-M] Documentation for platform interfaces
Is there somewhere a high-level documentation for the platform interfaces that are here:
https://git.trustedfirmware.org/trusted-firmware-m.git/tree/platform/includ…
What are the dependencies of the services to the platform files?
For example, when is nv_counters used?

Hi Anton,
I would like to give a brief introduction for a mechanism which would improve the coding efficiency and performance for RoT Service API by avoiding 'psa_connect'/'psa_close'.

Hi Raymond,
Sorry for the trouble. Sorry that I cannot find a Crypto test case with index 250.
Could you please share more details and error logs of this test case?
Best regards,

Subject: [TF-M] PSA Crypto failure with addition of persistent keys
Hi Jamie,
With the addition of persistent key support, we have seen the PSA Crypto test hang at test 250. Although we originally saw this with PSoC64, I was able to reproduce this problem on a Musca-B1. Can you please have a look please? Note that the behavior is not always the same. I have 2x Musca-B1 boards and they both failed the first time I ran the PSA Crypto test suite. However, they both did not freeze on a 2nd run. Possibly a stack issue such that the behavior is dependent on what is in stack.
Thank you,
Ray

Looks no more feedbacks. We will start creating it and call for review when finished.

Hi Reinhard,
Thanks for your feedback, and let's see if others would give more comments.
Will broadcast the implementation after it is created. Before that we need to know if some users (especially those developing secure partitions under library model) got comments on this.
Also, I think this update could help the first point in your list.

Subject: [TF-M] [RFC] The veneer usage under library model (Ken Liu)
Ken,
This is the answer to "What do you think about this update?"
When external TF-M APIs do not change, there should be no user impact. As the veneer is just an internal implementation of parameter passing, changing the veneer implementation would be just fine.
I made some suggestions here
https://lists.trustedfirmware.org/pipermail/tf-m/2020-March/000805.html
I would be happy to review your implementation in case that you have doubts.
Best regards
Reinhard
Hi all,
Hope you are doing well. May I ask for your review on the latest Profile Small design?
The design has been updated with following major changes:
* The default AES mode is changed to CCM mode from CBC mode, to achieve more secured connection.
* More details on the use case of Profile Small
Please review the document on https://review.trustedfirmware.org/c/trusted-firmware-m/+/3598.
Please feel free to comment. Thank you!
The patch set is updated as well, following the latest design.
Please check it on https://review.trustedfirmware.org/q/topic:%22profile-s-config%22+(status:o…. Compared with previous versions, CCM is supported and some configurations are selected to optimize the Crypto memory footprint.
Best regards,
Hu Ziji
