Send streams too/from where, the question is awfully vague and open-ended.

You basically specify source and destination addresses, along with a length. The stream/channels being used will depend if a peripheral is triggering the transfer.

Hi,

Thanks for answering.

in the meanwhile i just want to load two streams with memory to memory data transfer.

i'm using the stm32f4 discovery board, and the DMA2.

if you have some example it'll be great.

Thanks
