Issue Details

I have compiled FPGA code, and I am trying to interface with it from my host. When I use the Open FPGA Reference and Invoke Nodes on my host VI, I get the following error:

Error -1073807346 occurred at Test.vi
Error occurred at VISA open and NI-RIO. The given session of object reference is invalid.
 

How can I fix this error and run my FPGA code?

Solution

To resolve this, you need to configure a resource for your FPGA device. Follow these steps to resolve the error:

1. Go to the Project Explorer window and right-click on your FPGA device. Select Properties.
 
3. In the resource field, type in RIO::INSTR.
 
​
3. Click OK.

You should now be able to run your FPGA VI without any errors.
