1. Replace the default files include/mbedtls/mbedtls_config.h and
tf-psa-crypto/include/psa/crypto_config.h with the chosen ones.
2. Use the MBEDTLS_CONFIG_FILE and TF_PSA_CRYPTO_CONFIG_FILE options of the
CMake build system:
2. Use the MBEDTLS_CONFIG_FILE and TF_PSA_CRYPTO_CONFIG_FILE CMake options. For
example, to build out-of-tree with the config-ccm-psk-tls1_2.h and
crypto-config-ccm-psk-tls1_2.h configuration pair:
cmake -DMBEDTLS_CONFIG_FILE="path-to-your-mbedtls-config-file" \
-DTF_PSA_CRYPTO_CONFIG_FILE="path-to-your-tf-psa-crypto-config-file" .
make
cmake -DMBEDTLS_CONFIG_FILE="configs/config-ccm-psk-tls1_2.h" \
-DTF_PSA_CRYPTO_CONFIG_FILE="configs/crypto-config-ccm-psk-tls1_2.h"
-B build-psktls12 .
cmake --build build-psktls12
The second method also works if you want to keep your custom configuration
files outside the Mbed TLS tree.
