  • PXI FPGA Module for FlexRIO

Software

  • LabVIEW FPGA Module

Driver

  • FlexRIO
  • NI-RIO

Issue Details

  • I am getting Error -61499: LabVIEW FPGA: An internal software error in the LabVIEW FPGA Module has occurred in an FPGA VI at compilation time or while editing a VI.
  • I get Error -61499 while editing an FPGA VI. The error refers to specific FPGA nodes, in my case, the Open FPGA VI Reference vi causes the error when I place it from the palette. 
  • An additional message may be attached saying : "Additional Information: Unsupported or incorrectly typed FPGA Device Family. Use lower case letters only", and may appear from configuration in the Getting Started Projects for RIO.

Solution

Try the following recommendations to attempt to resolve this error:
  • Confirm that you are using a supported OS and LabVIEW version for your compile software.
  • Delete the bitfiles and allow them to be regenerated.
  • Use the Compile Cloud Service or a compile server farm.
    • If a remote compile session does not fix the issue and you have the appropriate Xilinx Compilation Tool installed, try to uninstall the Xilinx Compilation Tool before compiling.
  • Ensure your project and VIs are located in the intended location.
    • If the file paths are too long, use the Files tab in the LabVIEW project to relocate your files.
  • Remove and recreate the build specification.
    • Delete and recreate the affected FPGA nodes.
    • If you are using local compilation tools, force reinstall the Xilinx Compilation Tool.
    • Force reinstall the LabVIEW FPGA Module.
    • Force reinstall any RIO Drivers.

    Additional Information

    Before LabVIEW 2018 FPGA, some Xilinx Compilation Tools were not supported on Windows 10.

    You can find which Xilinx Compilation Tool is compatible with your NI FPGA Hardware and download the appropriate version to your development machine.
