recompile

[SteCla]

After a while I always get this error when clicking on run:

Error -1074100594 occurred at niUsrpRio Config v1 Host.lvlib__Check Versions.gvi:1040001

Possible reason(s):The Configuration library signature on the host does not match the FPGA. Recompile FPGA.Complete call chain: niUsrpRio Config v1 Host.lvlib__Check Versions.gvi:1040001 niUsrpRio Config v1 Host.lvlib__Open 2.gvi:280001 niUsrpRio Config v1 Host.lvlib__Open.gvi:3720001 Open Device.gvi:2740001 Full Duplex Streaming (Host).gvi

Why is this? I don't do major changes..

Are you running into this problem in LabVIEW Communications?

If you are, I would post it in the LabVIEW Communications forums because it is a bit more of a specialized product knowledge.

Aside from that you mentioned that you didn't do any major changes, but did you change the FPGA application at all? The compiler does try to be smart but it does mess up sometimes.  The best way around this if you are not actually changing anything in your FPGA application is to reference a bitfile. That's what I would do in LabVIEW at least.

Labview Communications indeed. I moved my question, thanks!

Refering to your answer:

How do you 'reference a bitfile' in Labview (Comm)?
