Hello,
I interface my Cyclone with a micron SDRam using the Altera SDR SDRAM Controller but it seems that there is something very wrong in what I do.
When I send a write command to the controller, what I get on the output using SignalTap is the write command issued to the SDRAM, but only 2 clocks later come the data. So the first two word I read are wrong, and the last two I write are lost.
I think the configuration of the controller and the sdram is right, it runs at 50 MHz with a CAS of 2 (since it seems from the doc that the controller cannot do 1)
If you have any idea ...
Thanks Nick
