NI 9862 and DMA FIFO

[Domenico_fed]

Hi to you all. We're trying to compile a FPGA file with 3 DMA into the project and a NI 9862 into the RT part (cRio 9116). During the compilation process we always have this error: Too many sets of DMA control lines have been requested or some requests are conflicting

We tried to follow the following solution (http://digital.ni.com/public.nsf/allkb/9B13EF13482F4EEC862578FE006EB4C2?OpenDocument) but we still have the same problem.

We're running Labview 2012sp1.

Hello Domenico,

Are you attempting to use the FPGA in hybrid mode with the scan interface? If you are, the scan interface requires 2 DMA channels, which could be the source of your error. I wasn't able to open your link, so my post may be off the mark.

Hi, we're using the system in FPGA interface.

Sorry about the link, it's: http://digital.ni.com/public.nsf/allkb/9B13EF13482F4EEC862578FE006EB4C2?OpenDocument
