Problem: I've recently upgraded my LabVIEW, LabVIEW Real-Time module, and LabVIEW FPGA module to a newer version. Do I need to recompile my FPGA bitfile? Solution: If your Open FPGA Reference function links to your FPGA VI, LabVIEW will require you to recompile it before you can deploy your RealTime VI. If you link the Open FPGA Reference directly to the bitfile that was compiled in the prior version, LabVIEW will not force you to recompile the bitfile. That said, new releases of the LabVIEW FPGA module (even minor upgrades, such as from LabVIEW 8.5 to 8.5.1) have been shown to have unresponsive FPGA I/O when linked to bitfiles from previous versions. As such, National Instruments always recommends recompiling your FPGA bitfile with the version of the LabVIEW FPGA module that matches the version of LabVIEW/LabVIEW RealTime that will be accessing that bitfile.
