Hi, from the data sheet of AM335x, it said the MPU have the Crypto Hardware accelerators feature. So I want to know what kind of AES Crypto does it support? Thanks very much.

    Hi,

    I can not find any reference about "Crypto Hardware accelerators (AES, SHA, PKA, RNG...)" in TRM "AM335x TRM spruh73c.pdf". Can you help to provide info about these functions and how to access them.  Thanks,
