How to use the DRAM of NI5641R?

[xk104@sina.com]

Hello

     How to use the DRAM of NI5641R? anyone could give me a example?

    I only have a NI5641R.

    I try the example of FleRio,which named "simple external Memory FIFO". and rewrite it in NI5641R target. compile is successful.

    but it always indicates the "FIFO is FULL"!

    please help.

Hello,

I have attached a code with this post that shows how to used the DRAM as a FIFO similar to what you were trying to do. One thing I would suggest is Enable FIFO Reads first, and then Enable FIFO Writes. If you have the FIFO write enabled and the FIFO Read is disabled you are going to see FIFO full. The code I have attached is compiled and I have tested it.
