thanks, avishay, for the suggestion. i checked the unassigned pins and they are already set to tri-state input, so i looked for other possible problems.

i noticed something else that is probably causing my problem - now i need help to resolve it. in sopc builder, i'm using the standard reference design but i have an error and a warning at the bottom message window of the gui.

the error says "one or more components could not be located (ddr_sdram_component). check Search Path[/b] under file->sopc builder setup... menu." I tried adding some directories like it said, but that doesn't seem to help. Next to the ddr_sdram component in the active components window, it says "(NOT INSTALLED)". Do I need to reinstall Quartus? How can I install just the missing component? (Where do I find it?)

The warning says "nios development board, cyclone ii edition: SSRAM data byte-lanes are swapped. Refer to the Nios Development Board, Cyclone II Edition Reference Manual." Is this normal for this board? Do I need to correct this?

Hello.

Maybe you need to install the Megacore IP library CD.
