Error Code -61499 when Running an FPGA VI on Develpement Computer with Siulated I/O

Solved!
Go to solution

Dear Forum

 

I have a problem with running my FPGA VI on the development Comupter with simulated I/O

 

I Created a testbench as described in

http://zone.ni.com/reference/en-XX/help/371599D-01/lvfpgaconcepts/test_bench_tutorial/

This works fine. I can read an write the I/O Nodes

 

But when I insert a read/write control node (from the FPGA interface palette) into my Host-VI to directly write a value to a Control on my FPGA VI, i get the error -61499

 

The error happens in the VI on my Hostcomputer ad the message is:

An internal software error on LabView FPGA Module has occurred. Please contact NI technical support.

 

The error does not happen, if I remove the read/write control, or if I dont call it.

The error does not happen, if I compile the fpga-vi and let it run on my fpga hardware. It happens only in the simulated mode.

The error happens in the simulated mode when i use the testbench for simulating input Signals, it also happnes, when I use random Input Signals.

 

It seems that the error does not happen during compilation. The simulated VI runs and the error happens, only when I call the read/write control.

 

Can anybody help me?

I appreciate every suggestion

 

Thanks

David

Is it possible, that i have to control the read/write nodes also in the testbench?

I ayctually dont think so, but im not sure.

Ok, the problem is solved, thanks to ni support who helped me:

 

The solution is, not to have spaces and end of lines in the names of frontpannel elements.

 

In simulated mode, a host-vi has problems to access frontpannel elements of the fpga-vi with the read/write node if the frontpanel elements have special characters.
