I am trying to use the Flash memory of a de2-70 Kit with a ro_zipfs (do fopen() and fscanf() operations), but I'm completely lost and can't find any examples online. I have to intantiate a Flash Controller module in SOPC Builder, right? But what controller (CFI, EPCS or Flash Memory Interface)? I also can't program the Flash with the Flash Programmer from the Nios II EDS. But I guess it is because i have no flash controller. Can someone help me on this? thank you.
