1. Building TF-M

Prepare the tf-m-tests repository inside the TF-M base folder.

cd <TF-M base folder>
git clone https://git.trustedfirmware.org/TF-M/tf-m-tests.git

There are two options for the TF-M build - with or without secondary bootloader (BL2).

1.1 Building TF-M demo with BL2

To build S and NS application image with BL2, run the following commands:

cd <TF-M base folder>/tf-m-test/tests_reg
cmake -S spe -B build_spe \
    -DTFM_PLATFORM=nxp/frdmmcxn947 \
    -DCONFIG_TFM_SOURCE_PATH=<TF-M base folder>/trusted-firmware-m \
    -G "Unix Makefiles" -DBL2=ON -DTFM_BL2_LOG_LEVEL=LOG_LEVEL_INFO
cmake --build build_spe -- install
cmake -S . -B build_test -G"Unix Makefiles" \
    -DCONFIG_SPE_PATH=<TF-M base folder>/tf-m-tests/tests_reg/build_spe/api_ns
cmake --build build_test

1.2 Building TF-M demo without BL2

To build S and NS application image without a BL2, run the following commands:

cd <TF-M base folder>/tf-m-test/tests_reg
cmake -S spe -B build_spe -DTFM_PLATFORM=nxp/frdmmcxn947 \
      -DCONFIG_TFM_SOURCE_PATH=<TF-M base folder>/trusted-firmware-m \
      -G"Unix Makefiles" -DBL2=OFF
cmake --build build_spe -- install
cmake -S . -B build_test -G"Unix Makefiles" \
      -DCONFIG_SPE_PATH=<TF-M base folder>/tf-m-tests/tests_reg/build_spe/api_ns
cmake --build build_test

1.3 Building TF-M regression tests

To build the S and NS regression tests without BL2, run the following commands:

  • Profile Medium:

cd <TF-M base folder>/tf-m-test/tests_reg
cmake -S spe -B build_spe -DTFM_PLATFORM=nxp/frdmmcxn947 \
      -DCONFIG_TFM_SOURCE_PATH=<TF-M base folder>/trusted-firmware-m \
      -G"Unix Makefiles" -DTFM_PROFILE=profile_medium \
      -DTEST_S=ON -DTEST_NS=ON -DBL2=OFF
cmake --build build_spe -- install
cmake -S . -B build_test -G"Unix Makefiles" \
      -DCONFIG_SPE_PATH=<TF-M base folder>/tf-m-tests/tests_reg/build_spe/api_ns
cmake --build build_test

1.4 Building TF-M regression tests with BL2

To build the S and NS regression tests With BL2, run the following commands:

  • Profile Medium:

cd <TF-M base folder>/tf-m-test/tests_reg
cmake -S spe -B build_spe -DTFM_PLATFORM=nxp/frdmmcxn947 \
      -DCONFIG_TFM_SOURCE_PATH=<TF-M base folder>/trusted-firmware-m \
      -G"Unix Makefiles" -DTFM_PROFILE=profile_medium -DTEST_S=ON \
      -DTEST_NS=ON -DBL2=ON -DTFM_BL2_LOG_LEVEL=LOG_LEVEL_INFO
cmake --build build_spe -- install
cmake -S . -B build_test -G"Unix Makefiles" \
      -DCONFIG_SPE_PATH=<TF-M base folder>/tf-m-tests/tests_reg/build_spe/api_ns
cmake --build build_test

  • Profile Small:

cd <TF-M base folder>/tf-m-test/tests_reg
cmake -S spe -B build_spe_small -DTFM_PLATFORM=nxp/frdmmcxn947 \
    -DCONFIG_TFM_SOURCE_PATH=C:/Code/tfm-upstream/trusted-firmware-m \
    -G"Unix Makefiles" -DBL2=ON -DTFM_PROFILE=profile_small -DTEST_S=ON   \
    -DTEST_NS=ON   -DTEST_S_CRYPTO=ON   -DTEST_NS_CRYPTO=ON   -DTEST_S_ATTESTATION=OFF \
    -DTEST_S_STORAGE=OFF   -DTEST_S_PLATFORM=OFF   -DTEST_NS_ATTESTATION=OFF  \
    -DTEST_NS_STORAGE=OFF -DTEST_NS_PLATFORM=OFF -DTEST_S_PLATFORM=OFF \
    -DTEST_NS_SFN_BACKEND=OFF -DTEST_S_SFN_BACKEND=OFF -DTFM_BL2_LOG_LEVEL=LOG_LEVEL_INFO
cmake --build build_spe_small -- install
cmake -S . -B build_test_small -G"Unix Makefiles" \
    -DCONFIG_SPE_PATH=C:/Code/tfm-upstream/tf-m-tests/tests_reg/build_spe_small/api_ns
cmake --build build_test_small
