LS1021A SEC CRCA Dynamic Custom Mode

[Xi-nanWang]

LS1021A, I use SEC for hardware CRC calculation, I can only run the STANDARD IEEE and IETF mode correctly, when it comes to Dynamic CUSTOM mode, the hardware will generate all ZERO results. The register configuration are the same except the mode selection AAI and Key Register. Did I miss any critical register bits? Or which registers should I consider to use CRCA dynamic custom mode?

Generating CRC with custom polynomials require a Job Descriptor that
is not in the standard JD library. Customers requiring custom crypto
operation descriptors are advised to request them through NXP

Resently I have encountered some problems when using SEC to calculate MD5. Since the source data size is too too big, i hope to splite it into chunks and calculate in times. Which registers should i concerned about and how to config? or does it need some sort of paid services again?

Nobody has any clue? Or my statement is too vague? Any answer would help.
