I would like to use EDMA or QDMA for a core to access information stored on external DDR2 memory. I'm using the TMS320C3472-EVM for my testing. I'm also going to have to use DMA eventually to transfer blocks of information from one core's cache to another, but for a first step, I'd like to be able to grab it from external ddr via DMA. Are there any good getting started guides on this or example projects? Thanks.
