I would recommend not using the university program core and starting with a known working SDRAM example. Test the example first to make sure your hardware is good.

If you do want to stay with the university core, make sure you verify that the core you are using is designed for the exact development board you are using. This includes the ram chips as they can change during a production run. The settings on an SDRAM controller depend on the exact ram chip being used as well as the geometry of the traces on the board. A core configured with the settings for a different board won't function correctly.
