Question

AES in STM32F423

Hello  for all

In last days i was begin to implementation AES to work on stm32f423
I am using example in NIST Special Publication 800-38A to take key-128 bit, input data that plain text , encryption and decryption data.
but nothing seems to work , when i print HAL_CRYP_GetError(&hcryp)
it return 0.

I hope my question clear enough.
Any tips for this.
best regard.

Dear @mick,

Can you please give more details on your code and  also to run default examples in HAL and see if working ? 

In this series Crypto engine is different and optimized for AES only vs others bigger variants . So may be the Software calls are not  correct.
