megaram function and DE2 board

Still very much a beginner here.

I am using a de2 board as my development board. I have have written a program which uses various Altsyncram for storing data.

When i run it on the simulator all seams fine and i can see the data values stored, but when i run in on the board it look like it does not store any data. I have set up both hex and mif files.

There is no cpu or anything flash just ins out and a bit of memory to store data.

Do you have to do anything to get the de2 to set up memory so the program will use this or am i missing somethig basic !!!
