Required GCC tools for reference implementation

by DeMars, Alan

Is there a compelling reason that the reference implementation of the PSA requires the use of the gcc-arm-none-eabi-6-2017-q1-update gnu tools? The linker in these tools generates a non-standard s_veneers.o file that cannot be consumed by some CLANG linkers. It should be a relocatable object file with absolute symbols, but instead it's static executable file. If I use a newer GCC linker (ie: gcc-arm-none-eabi-7-2017-q4-major) for the final link of the secure image, the generated s_veneers.o file is of the correct type. Alan DeMars

[TF-M] How to run PSA API compliance tests with TF-M SST service

by Marc Moreno Berengue

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_ap…) 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.

How to run PSA API compliance tests with TF-M Crypto

by Antonio De Angelis

Hi all, It's possible to run a subset of the PSA API Compliance tests with the TF-M Crypto service by following the instructions below (it assumes 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/tree/ew_beta0 (ew_beta0 branch of the PSA API Compliance tests repo) 2. Checkout https://review.trustedfirmware.org/#/c/trusted-firmware-m/+/561/ 3. Copy the interface/include/psa_crypto.h to interface/include/psa/crypto.h as this is the header name expected by the PSA API Compliance tests 4. Build the Crypto 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) * The list of tests being run is specified in the file psa-arch-tests/api-tests/dev_apis/crypto/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 crypto --include ../../trusted-firmware-m/interface/include --archive_tests" 5.

We are currently working on fixing the remaining failures. Thanks, Antonio

IPC patches merged into branch 'feature-ipc'

by Ken Liu (Arm Technology China)

Hi Subscribers, Group of IPC patches has been merged into branch 'feature-ipc'. The features are: * PSA Firmware Framework API (based on scheduler and message queue) and example partitions. * Isolation level 1 * Verified on AN521 You can find the design link here: https://developer.trustedfirmware.org/w/tf_m/design/ipc_design/ Some issues are identified and need to be solved. We will publish the list of improvements soon. Any feedback please mail to tf-m(a)lists.trustedfirmware.org<mailto:tf-m@lists.trustedfirmware.org> You can also create questions and issues at https://developer.trustedfirmware.org Thanks. -Ken

Re: [Tf-m] Replace custom code generating scripts with Jinja2

by Ken Liu (Arm Technology China)

Hi Mate, Thanks for the proposal. It looks nice. I have read the "Improvements over the current solution" part and I think the "More advanced functionality" is the point I am interested in. There are some necessary jobs to be done in the code generating scripts for IPC; hope using this tool could help on that. One thing we are investigating is: * We need to put PSA RoT and APP RoT into different groups in linker script; current tool just put all partitions together and ignores partition type. Can you help to check if the new tool could make this change easier? Thanks. -Ken ________________________________ From: TF-M <tf-m-bounces(a)lists.trustedfirmware.org> on behalf of Mate Toth-Pal via TF-M <tf-m(a)lists.trustedfirmware.org> Sent: Monday, January 21, 2019 8:37:58 PM To: tf-m(a)lists.trustedfirmware.org Cc: nd Subject: [Tf-m] Replace custom code generating scripts with Jinja2 Hi All, Based on the design proposal published here: https://developer.trustedfirmware.org/w/tf_m/design/code_generation_with_ji… I am planning to replace the code generation tool currently used in the TF-M with the Jinja2 template engine.
