cRIO FPGA won't compile, gives Error 1055

[Paul@LeT]

When I compile the FPGA, I get Internal software error: 1055 -

----------

Error 1055 occurred at Property Node in nirviGenerateHdlName.vi->nirvififoExtractFifoFromXNode.vi->FifoGetModInfo.vi->FifoGetModInfo.vi.ProxyCaller

Possible reason(s):

LabVIEW:  Object reference is invalid.

-----------

I am using an FPGA VI that was built in a different project.  The FPGA VI was working in the other project.  I removed and added the FPGA VI from the project with no improvement.

Can you post the bad project and FPGA VIs?

One idea that I think is worth trying is to delete and recreate the FIFO item(s) in the LV Project. Additionally, you can try replacing the nodes in the FPGA VI that communicate to the board.  I assumed from the error that your project has a FIFO item.

JMota, I fixed the problem by making a blank VI in the project and copying everything from the problem VI.  Then I removed the problem VI from the project.  This solution was suggested by an NI Applications Engineer.  Apparently the project has gotten confused.

Good to hear you have a solution, and thanks for posting back how you fixed it.
