Some DE1 boards use different SDRAM chips which aren't compatible with the Minimig SDRAM controller out-of-the-box. I also believe that SDRAM problems can be mitigated to some extent via timing constraints in Quartus. (2) Reportedly some SD cards aren't compatible with the Minimig SD controller. People have had success with some previously failing SD cards using certain format utilities. Personally, I've had mixed success with the various releases of Minimig on the DE1, DE2 and my own hardware platform, both with .SOF releases and my own builds with various versions of Quartus. Unfortunately, until timing issues etc are resolved it's a case of "luck of the draw" for the DE1/2 builds as far as I can tell. Seems most people have managed to find a version that works on their hardware. I've been menaing to take a closer look at the DE1/DE2 problems but haven't found the time. Unfortunately there's probably not a lot you can do except try the different builds and different SD cards. Not sure anyone else can help you either?!? Anyone else disagree with this summary?
