I'm about to submit a set of cleanup patches but have not been able to find the contribution guide. Most of the useful documentation I've found seems to be related to TF-A.

Re: [TF-M] Is TFM_PSA_API broken?

by Ken Liu (Arm Technology China)

Hi Andrej, tfm_thrd_context_switch() does not want to thread to be running is NULL. And actually it should never happen in existing implement unless IRQ is involved. Here is a patch for fixing this, but I am not sure if you are under the same case we met: https://review.trustedfirmware.org/c/trusted-firmware-m/+/959 I am curious about your environment, at least one partition will be running in latest master branch. Can you share me your changes? Are your using original TF-M and which configuration file you are using?

Re: [TF-M] Is TFM_PSA_API broken?

by Andrej Butok

Hi Antonio, So, I have disabled Platform and Log services. Also, TFM_NS_CLIENT_IDENTIFICATION have to be undefined for IPC. Is this correct? After that it becomes compliable. But when starting the regression tests, I am getting assert in tfm_thrd_conext_switch(). Terminal log: [Sec Thread] Secure image initializing! NS code is running... #### Execute test suites for the Secure area #### Running Test Suite PSA protected storage S interface tests (TFM_SST_TEST_2XXX)... > Executing 'TFM_SST_TEST_2001' Description: 'Set interface' Assert:tfm_thrd_context_switch:170 So I am stuck now, and no matter what to use the IPC or the Function API approach. Probably, something serious happened during last two weeks (before it worked), may be in platform dependent code. NOTE: I am using a different platform LPC55S69 and IDE approach (not cmake). Any tips?

Feature request

by Thomas Törnblom

While working on porting TF-M to the IAR toolchain, I've run into a couple of issues I'd like to discuss. 1) The duplicated REGION/REGION_NAME/REGION_DECLARE macros. Why are these not defined in an include file instead of being defined in eight different c files? I see that they are also defined in spm_db.h, but that is only included in spm related files. 2) I suggest adding a toolchain related include file that should be included in every source file that is part of TF-M. This could be something similar to cmsis_compiler.h, where a toolchain vendor could add stuff that only relates to a specific toolchain. In our case that could include things like: --- #ifdef __ICCARM__ #define $$ZI$$Limit $$Limit #define $$ZI$$Base $$Base #define Image$$ #endif --- Ideas? /Thomas -- *Thomas Törnblom*, /Product Engineer/ IAR Systems AB Box 23051, Strandbodgatan 1 SE-750 23 Uppsala, SWEDEN Mobile: +46 76 180 17 80 Fax: +46 18 16 78 01 E-mail: thomas.tornblom(a)iar.com <mailto:thomas.tornblom@iar.com> Website: www.iar.com <http://www.iar.com> Twitter: www.twitter.com/iarsystems <http://www.twitter.com/iarsystems>

[RFC] Move configuration files into specified directory

by Ken Liu (Arm Technology China)

Hi, Since the number of configuration files is increasing, let’s move the configuration files (ConfigXXXX.cmake) into specified directory. This would reduces the files under root directory and makes the structure more clearer. I have created the issue and patch for it: https://developer.trustedfirmware.org/T394 https://review.trustedfirmware.org/c/trusted-firmware-m/+/1234 IMPORTANT NOTES: To be compatible with the existing building configurations, the existing configuration files have been forwarded into the corresponded configuration file under ./configs. Which means there are two set of configuration files under sources tree at current – but this will change soon. There is a warning while you are building with root configurations files: “Please use the configs available in the ./config sub-directory.” So please: - If you are planning to create new configuration, create it under ./configs instead of root directory - The reference of configuration files under root directory will be removed soon, please change your build system setting to reference the configuration files put under ./configs Any feedbacks please reply this mail or put comments under the issue, thanks 😉 -Ken

PSA Developer API compliance tests

by Antonio De Angelis

Dear all, The new tag which has just been made available from the psa-arch-tests, available here: https://github.com/ARM-software/psa-arch-tests/releases/tag/v19.06_API0.9 is the one that has to be used to be able to verify PSA Developer API compliance with the latest TF-M. The procedure to follow to build and run the tests remains the same. Thanks, Antonio

Supported versions of the Armclang compiler in the TF-M build

by Antonio De Angelis

Dear all, We are considering to drop support for older versions of the Armclang compiler (i.e. 6.7 and 6.9) to focus support on newer releases (thus increasing the requirement on Armclang version to 6.10 or higher). https://developer.trustedfirmware.org/T392 https://review.trustedfirmware.org/c/trusted-firmware-m/+/1223 If you have any specific requirement to use Armclang 6.7 or 6.9, please get in touch here or on the review. Thanks, Antonio

Two changes merged by mistake

by Miklos Balint

Hi all, Two changes that have underwent multiple rounds of review and test were accidentally merged instead of being pushed for review and final approval. I was at fault, apologies for that. Additional tests of the changes flagged up no regression. Let me know if you have any concerns or questions, Thanks and regards Miklos
