Error -63001 NI-RIO FPGA Communications Occurs With DMA Transfers From Host to FPGAPrimary Software: LabVIEW Modules>>LabVIEW FPGA ModulePrimary Software Version: 1.0 Primary Software Fixed Version: N/A Secondary Software: Driver Software>>NI-RIO Hardware: CompactRIO>>Controllers>>cRIO-9004
Problem: I am trying to do a Direct Memory Access (DMA) transfer from the 900x compactRIO Real-Time (RT) controller to the FPGA. The FPGA code compiles; however, when I run the code I get a Real-Time error saying the following:
Solution: As stated in the NI-RIO driver readme, DMA is not supported from the host to the FPGA on the cRIO-900x series. The cRIO-901x controller supports DMA transfers from host to FPGA and FPGA to host while the cRIO-900x series controllers only support FPGA to host DMA transfers. Therefore, LabVIEW returns an error if you try to transfer using DMA from the cRIO-900x controller with any NI-RIO version.
