STM32MP157F: DMA support on USB/CRYPTO/eMMC

ALong.4

‎2023-05-19 6:16 AM

Hi,

I am interested in using the STM32MP157F for the following tasks:

  1. Receiving data from USB 2.0.
  2. Encrypting the received data using AES 256.
  3. Storing the encrypted data in an external eMMC.
  4. Preferably utilizing DMA for efficient data transfers.

I would like to know if it is possible to configure DMA channels to enable direct peripheral-to-peripheral communication, such as USB 2.0 -> CRYPTO (AES 256) -> eMMC.

Additionally, it would be greatly appreciated if you could provide an example or reference on how to utilize DMA with USB, cryptographic operations, and eMMC.

Thank you.

Best regards,

Alessandro
