Re: [TF-M] Integrating a different RTOS in tf-m-test - TF-M

4 Nov 2020

      Just adding some hints from the TF-M point of view.
The TF-M test cases are RTOS independent.
And test entry functions are provided for integrating the tests to any RTOS - test_app()
You just need to call them in your application thread.
Of course, you need to implement the os_wrapper APIs as well.
You can refer to the os_wrapper_cmsis_rtos_v2.c for details.
The old build system of TF-M used to provide libraries of the tests.
The new build system is not having those yet. So the source codes need to be built.
The test case libraries should be added back to the new build system and then integrating tf-m tests to RTOS should be much more direct.
Best Regards,
Kevin

Good spot Antonio, those docs are out of date. I'll try to get them updated before the code freeze.

Hi Raef,
I agree with you, also reading the documentation https://ci.trustedfirmware.org/view/TF-M/job/tf-m-build-docs-nightly/lastSta... (even if it seems obsolete since some files are missing). For example, are now the static library for the test included in the one you mentioned?
I'm using the module offered by zephyr to build and import the tfm, but I get a lot of missing references. 
Further, I searched in the install directory built by tfm and I cannot really find all of them.

    One of the things tfm produces is the NS api static library, which should be found in `interface/libpsa_api_ns.a`. There is also a ns platforms static lib in the same directory. I'm not sure how easy it is to pick these up from the zephyr buildsystem, but those should contain the symbols you want.

    Hi Kevin,
    Thank you for your message.

    I’m trying to create a zephyr application copying the tfm-test non secure application (https://github.com/zephyrproject-rtos/trusted-firmware-m/blob/master/tf-m-te...).

    The only thing that is not clear is how to include the tfm platform code (e.g., https://github.com/zephyrproject-rtos/trusted-firmware-m/blob/master/trusted...).
    I suppose as a static library from the zephyr tfm module but I cannot really find how.
    Can you point me to the right direction?
    Or do you have a different way to run the tfm-tests?

    Best,

    Hi Antonio,

    There is currently an issue filed in Zephyr to add a new sample application that will make it easy to run the PSA API tests via Zephyr, but it we're currently working on finalizing higher priority changes before the 1.2 code freeze later this week: https://github.com/zephyrproject-rtos/zephyr/issues/29476

    So, there isn't an 'easy' way to build these tests in Zephyr today out of the box using Zephyr as the RTOS on the NS side, unless you want to have a go at it yourself in the short term while we try to make sure Zephyr is ready for the changes in T-M 1.2.

    Best regards,
    Kevin

    Hi all,
    I wanted to use some other RTOS in the NS side while testing tf-m.
    Is there a simple way to use the Zephyr kernel or FreeRTOS in the tf-m-test (-DTEST_S=ON, -DTEST_NS=ON) instead of the default RTX?
