Honored Contributorfreeck, are you using a hardware reference design, or is it for your own board? Also what memory are you attempting to download to (if you have more than one memory device you may want to try compile the code into another memory with the IDE). If that fails as well then that would help rule out whether it's the memory failing. Another thing to check is that you have all your I/O set properly, and that you have all unused I/O pulled to the appropriate signal (with the Nios II hardware reference designs we set all unused I/O to tristate in the Quartus II device settings page)
