mbed-crypto APIs not working in either SBSFUAppliSecure or SBSFUAppliNonSecure

[Nitin]

Hi I am working on SBSFU Application project from STM32U585 project. And I am trying to use mbed-crypto APIs like SHA512 APIs as below

mbedtls_platform_setup(NULL);

mbedtls_sha512_init(&sha512_context);

mbedtls_sha512_starts(&sha512_context, 0); // 0 for standard SHA-512

mbedtls_sha512_update(&sha512_context, data, data_len);

mbedtls_sha512_finish(&sha512_context, sha512_hash);

for(int i =0;i<64;i++)

{

    printf(" %x",sha512_hash[i]);

}

/printf("\n SHA512 Computed");

mbedtls_sha512_free(&sha512_context);

What I am experiencing here is that I am seeing frequent reset of the controller  during execution. I would like to know the possibility of same situation ever faced by other person also. Or is their any other configuration I have enable in default config file.

Need help, thanks in advance...

Hello @Nitin ,

In which context those calls are used? if it is in the non-secure project context you need to do so with PSA API calls to call for crypto services from secure in a proper way this usecase is implemented in the TFM application example project which can be found under:

STM32Cube_FW_U5_V1.6.0\Projects\B-U585I-IOT02A\Applications\TFM
see TFM\TFM_Appli\NonSecure\Src\tfm_app.c
