I have recently setup the XUP Virtex II Pro Evaluation board. i have managed to get this board working and running simple programs.
I now want to be able to write data to an on board DDR SDRAM card. Does anyone know how i go about this ? i have tryed reading the user guide but i does not really give u walk through of how to do this. All i really want to do just now is a simple thing like store the values of an output in the RAM.
I was thinking of just taking the values on the user LEDS and storing them.
Re: Writing data to on board DDR SDRAM on Virtex II Eval bo
Unless you have somehow erased it the eval kit comes with a DDR controller already installed. This will take care of the clocking, handshakes, etc. You will just need to write some code to provide the data to the datapath.
For more info take a look at Xilinx appnote XAPP688 and even do a search on DDR on the Xilinx website as well.

hey does the eval version has coregen... you can generate a HDL model file for the RAM in your fpga... when you fuse it this HDL model will be mapped to the RAM in your fpga... hope i'm right...
