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.
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.
