Can't make RT use generic FPGA FIFO

Question

Hi all,
On a cRIO, I'm making a TCP server in RT that feeds data to a DMA FIFO for FPGA consumption.  We are setting up multiple servers where each feeds a different DMA.  (No, I don't want to merge and multiplex to single DMA).
I want a single RT program that takes a FIFO reference so that I can reuse the same RT code for different FIFOs.  I can define a FPGA FIFO reference control,
but this only supports writing a single element at a time (or two on our target if you select peer-to-peer streaming for the FIFO).  I have tuned the RT program for performance, and looping over thousands of elements per second in RT is NOT the solution.  I want to use the "other" FIFO write which supports arrays - the one I can reference from an FPGA reference as follows:
However, using the FPGA reference I believe requires a particular named FIFO - therefore tying the RT code to a particular FIFO.
Any ideas how to do this?

Answer 1

All,
Thanks for the advice.  I'm trying to create a basic test using the Advance Sessions Sources and am getting a FIFO name error (-61206) from the Get Single Resource Session node.  The messy diagram below is showing the test VI on the right and a client VI on the left.  The idea is to pass an FPGA reference and the FIFO name "FpgaDataIn" and the test VI grabs the FIFO by name and writes to the FIFO.  
One issue to overcome is my beginner skills: the passed FPGA reference needs to be compatible with the FPGA reference control - which defeats the purpose of supporting generic FPGA references.  There must be a way to specifiy a control that accepts a generic FPGA reference (dynamic FPGA cast?  (which I've never used)).
Putting that issue aside for a moment, even when I define a FPGA reference control with a signature compatible with the passed FPGA reference I still get the 61206 error.  I noticed issues related to upper/lower case and tried everything lower case (I THINK - I'm not positive I did it completely - but it's tedious with the FPGA reference signatures).
I read how the Get Single Resource Session needs a constant reference with a single "FIFO" fifo and have that.
Any tips?
Thanks!
