Hi,

After enabling MBEDTLS_NO_PLATFORM_ENTROPY and MBEDTLS_SHA512_C , mbedtls_ctr_drbg_seed is returning 0x0034 (MBEDTLS_ERR_CTR_DRBG_ENTROPY_SOURCE_FAILED)

But if I just enable MBEDTLS_NO_PLATFORM_ENTROPY and keep MBEDTLS_SHA512_C disabled, it does not return any error for mbedtls_ctr_drbg_seed.

My project uses certificates with SHA384 signature, so it requires MBEDTLS_SHA512_C to be enabled.

MBEDTLS_NO_PLATFORM_ENTROPY and MBEDTLS_SHA512_C both needs to be enabled in my project , but Iam facing issue with  mbedtls_ctr_drbg_seed returning 0x0034. Please guide me on this. What might be the reason for mbedtls_ctr_drbg_seed to fail while enabling MBEDTLS_SHA512_C.

How to overcome this issue?
