IF RIO DMA ch3

[Ex-NISH2]

I set up 4x FIFO for data transfer from IF RIO to the host.  They are using DMA ch0 to ch3.  But the one uses ch3 does not work.

The read node on host reports no data available (by reading number=0).  But the FIFO full flag is true at the FPGA.  Did I miss something.

Hi Ex-NISH2

Unfortunately, you have found an issue we discovered.  DMA on CH3 doesn’t seem to be working.

I’m trying to check to see if this was fixed in NI-RIO 2.1.  I’ll have to make a small application to test this in the next few days if I don’t hear back from the NI-RIO group.
