Hello

  the only available test / example is  sm_test, which  is provided as Linux BSP test.
Please check  drivers/crypto/caam/sm_test.c in BSP sources.

Have a great day,
Yuri

Hello,

   yes, You are right. Basically CryptoDev/OpenSSL with storage  is expected  

under Linux 4.2.

Yes, is not supported yet by NXP.
