STM32F401 HardFault when run the AES encryption

Posted on July 20, 2015 at 09:48

I would like to use the driver of AES encryption,

but every time the CRYP->CR run, it will go to hardfault.

I have no idea the reason.

Thanks!

Have you checked if F401 has this peripheral?

You probably didn't, so I will tell you. It does not have it.

Only F415, F417, F437 and F439 have it.

Thanks,

I did not expect the peripheral lib have it but actually it not.

The standard parts don't have the CRYP/HASH peripheral due to export controls. There are specific part# which have them.

ST has a crypto library that supports software and hardware implementations. You have to meet specific requirements to order it.
