9M2443 External DMA Example

Has anyone had any success implementing an external device that uses DMA?

My application involves using an FPGA as an external SRAM style device (preferably Synchronous mode) but then also as a DMA device.

As most of you already know, the Samsung documentation on DMA to external devices is pretty thin – so I figured I’d ask here since Digi support doesn’t seem to even know what DMA is.



Take a look at the ethernet drivers, I believe that they use DMA. (I could be thinking about a different platform though)
