AM2634-Q1: Issue with DTHE_SHA_open API

Tool/software:

Hi TI Team,

I am checking the SHA256 example on the AM2634 KIT. The example builds successfully and runs as expected. However, when I port the code into my project, execution gets stuck after calling the following API: DTHE_SHA_open. Could you help me understand why this might be happening?

void crypto_sha_256_main(void)
{
    DTHE_SHA_Return_t   status;
    DTHE_Handle         shaHandle;
    DTHE_SHA_Params     shaParams;

    /* Opening crypto driver */
    shaHandle = DTHE_open(0);
    DebugP_assert(shaHandle != NULL);

    /* Opening sha driver */
    status = DTHE_SHA_open(shaHandle);
    UPRINTF("\n\rSHA Status: %d\n\r", status);
    if (DTHE_SHA_RETURN_SUCCESS != status) {
        return;
    }

}

Thanks,
Rahul
