Hi all,

The Secure Storage (SST) service has been updated to align it with the PSA Protected Storage APIs version 1.0. There are a set of patches which implements this change. Please, find more information about those changes in the following ticket: https://developer.trustedfirmware.org/T218

It's possible to run the PSA API Compliance tests (https://github.com/ARM-software/psa-arch-tests/tree/master/api-tests/dev_api...) with the TF-M SST service by following the instructions below.

(The instructions assume that psa-arch-tests and trusted-firmware-m directories are at the same level in the filesystem):

1. Checkout https://github.com/ARM-software/psa-arch-tests/ 2. Checkout https://review.trustedfirmware.org/#/c/trusted-firmware-m/+/589/ 3. Copy the `interface/include/psa_protected_storage.h` to `interface/include/psa/protected_storage.h` as this is the header name expected by the PSA API Compliance tests 4. Build the SST tests for the PSA API compliance as described in the `psa-arch-tests/api-tests` for one of the supported targets, providing the include path of the TF-M interface (i.e. trusted-firmware-m/interface/include). Set crypto and internal trusted storage as not implemented in `psa-arch-tests/api-tests/platform/targets/<TARGET_NAME>/Makefile`. Set PSA_CRYPTO_IMPLEMENTED:=0 and PSA_INTERNAL_TRUSTED_STORAGE_IMPLEMENTED:=0 * The list of tests being run is specified in the file `psa-arch-tests/api-tests/dev_apis/protected_storage/testsuite.db` * For example, this command will build the tests for AN521 "./tools/scripts/setup.sh --target tgt_dev_apis_tfm_an521 --toolchain ARMCLANG --cpu_arch armv8m_ml --verbose 2 --suite protected_storage --include ../../trusted-firmware-m/interface/include --archive_tests" 5. Build TF-M by using the ConfigPsaApiTest.cmake, enabling the PSA API Compliance tests for SST service by adding the following cmake switch during the configuration step: "-DPSA_API_TEST_SECURE_STORAGE=ON" * For example, this command will build the TF-M + NS app with PSA API Protected Storage tests for AN521 "cmake -G"Unix Makefiles" -DPROJ_CONFIG=`readlink -f ../ConfigPsaApiTest.cmake` -DTARGET_PLATFORM=AN521 -DCOMPILER=ARMCLANG -DPSA_API_TEST_SECURE_STORAGE=ON ../"

This will make our NS test app run a subset of the PSA API compliance tests for SST service.

Thanks, Marc Moreno
