STM32MP157F: DMA support on USB/CRYPTO/eMMC

[ALong.4]

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
