DMA controller loop/circular transfer, how to?

Hello all, I would like to use a DMA controller to fill a SDRAM memory in a "circular" way (as a circular buffer). I currently use the DMA controller (provided by Altera) to fill the memo...

Hi,

I really want to set my DMA to work in loop/circular also. How did you do it? I used to write an infinite loop to loop the receive request (from stream to memory) but I need CPU to initialize the request.

How about your method? Do you need any interaction from the CPU?

Thanks very much,

Pat
