This document contains the LabVIEW NXG FPGA Module known issues that were discovered before and since the release of LabVIEW NXG 5.1 FPGA Module. Known issues are performance issues or technical bugs that NI has acknowledged exist within this version of the product.
Not every issue known to NI appears on this list; it is intended to show the most severe and common issues that you may encounter and provide workarounds when possible. Other technical issues that you may encounter could occur through normal product use or system compatibility issues. You may find more information on these issues in NI’s Product Documentation, Knowledgebase, or Community.
Renaming an FPGA Application Breaks Associated Open FPGA VI Reference Nodes Referencing That Application
Renaming an FPGA Application breaks associated Open FPGA VI Reference nodes referencing that application because the 'Rename and Update' dialog fails to automatically update the reference to use the new name.
Manually point the Open FPGA VI Reference to the correct FPGA Application.
