How to run the programs in mbedtls?

[aisha11 (Aisha Junejo)]

I have downloaded “Mbed TLS” from https://github.com/ARMmbed/mbedtls. I compiled it with the make command and it is working fine. Now, I want to execute “pk_sign.c” given in programs directory. I created a directory pk-sign and then executed the " new mbed" and “mbed deploy”. I put the pk-sign.c code in main .cpp and compiled it using, “mbed compile --target NUCLEO_L152RE --toolchain GCC_ARM”. The compilation is fine but when I flash the binary on the NUCLEO-L152RE, I am getting the following errors.

Errors

MBEDTLS_BIGNUM_C and/or MBEDTLS_ENTROPY_C and/or MBEDTLS_SHA256_C and/or MBEDTLS_MD_C and/or MBEDTLS_PK_PARSE_C and/or MBEDTLS_FS_IO and/or MBEDTLS_CTR_DRBG_C not defined.

Hi @aisha11
The examples in the Mbed TLS repository are targeting local desktop OS(e.g. Linux \ Windows) .
these are not meant to work with Mbed OS.
If you are looking for example applications for Mbed OS, you can find them in

• https://github.com/ARMmbed/mbed-os-example-mbed-crypto
• https://github.com/ARMmbed/mbed-os-example-tls

If you would like to utilize these examples, then you should change them not to use MBEDTLS_FS_IO ( I believe this is the only difference, except for platform specific configuration, such as MBEDTLS_CTR_DRBG_C )
