AM5728: Questions about DMA controllers

Kenji Kawaguchi

Part Number: AM5728

Hello, experts,

Do both System DMA and Enhanced DMA support the transport like below?

*DDR3 Memory(AM5728 local RAM) < -- > PCIe < -- > HOST PC Memory

Thanks.

You can use either System DMA or EDMA to move data from application into the PCIe memory space mapped in DDR.

PCIe fabric will move the data from PCIe memory space thru PCIe bus. Vice versa.
