Hi,

Looks like I was too quick in sending out the mail.

I found the issue, sha256.c is used for both SHA256 and SHA224. So, only if both of these are accelerated, the file will not get compiled.

Regards,

Hi,

I am trying to use the MACRO’s defined at - https://github.com/Mbed-TLS/mbedtls/blob/development/docs/driver-only-builds.md to enable driver only build.

As mentioned on the page I tried to do this for SHA256. However, the code in sha256.c isn’t ifdefed by “MBEDTLS_PSA_ACCEL_ALG_SHA_256” so still gets compiled ?

Can you point me to what I am missing here ?

Regards,

Ruchika
