FPGA Interface Error 65218

[benjamin-hinrichs]

My FPGA on cRIO 9039 suddenly stopped generating intermediate filesthis morning with error 65218. The error description "A module in your project contains invalid module support files. Please contact the module vendor." was ever so helpful (which module??).

After some hunting for the offending file in my source code, it turned out to be either a failed experiment with xilinx ip core (which I deleted from source code) or some leftover compilation cache. Deleting all files and folders from C:\NIFPGA\compilation and C:\NIFPGA\iptemp solved my issue.

I'm leaving this solution in the forums in case somebody else runs into this message in the future.

In my case clearing the c:\NIFPGA folders did not solve the problem. Error occurred after I recompiled an old driver code for a custom developed cRIO module using a newer version of LabVIEW and uploading the code on GitHub. Before uploading I separated the compiled code from source file from all VIs as I do for all other VIs before initial committing. It seems that in this case this is not the right way because the driver release files must include the compile code also otherwise you get this error. So if you are developing a driver for a custom cRIO module using the MDK, make sure you disable "Separate compiled code from source file" for all VIs before exporting in release mode!
