Hello,
I need to create a custom peripheral that DMA's data to the DDR SDRAM on the ML403 board. My custom componet & the DDR SDRAM reside on the PLB bus. Does anybody have an example of how to do this? The template that XPS generates does not provide any details and as everyone knows, the xilinx documentation is pretty poor.
Thanks in advance
Harry
If you are using the wizard, study the user_logic.vhd Then take a look at IPIF (proper version) DMA/SG engine about registers. Remember that DMA input data are a peripheral internal register. I tried this route with OPB bus and the DMA engine does not work properly. Maybe you have more luck with PLB and use EDK 8.2 (they say some modifications were made regarding this issue). For a realy high performance system you better use MPMC2
Cheers,
Guru
