If I understand right, you are operating the controller with a design of your own. The most likely explanation would be a mísunderstanding of interface signals and timing, to my opinion. Did you try with the test driver before? By modification of the test sequence, you should be able to perform single writes and reads also.

I also didn't understand exactly, how you performed the continuous operation. With sequentially incremented addresses? With random data?
