spartan 3e starter kit ddr
Hi,
I just bought a Spartan 3E Starter Kit from Xilinx and it seems that there is a problem with the DDR chip.
To make a simple test of the board I made a project in EDK including the DDR controller.
I also included the memory test and an uart for std i/o. When running the memory test all fails, (8, 16 and 32 bit) The project is made from the wizard and I've checked that the revision of the board is correct.
After a few hours of investigating it seems that I can write and immediately read it back, but if I "wait" a few lines of code the result is corrupted when I read it back.
I've check the ".ucf" file for any errors but it still doesn't work.
Is my board damaged?
Best Regard
