FPGA

I have recently updated to Windows 7 and LabView 2013. After recompiling the FPGA target and updating the reference I can run the main code but get the following error:

After checking the list of devices in MAX and comparing it with the one in the Windows device manager, it looks like LabView only sees the board that FPGA is on but not FPGA itself (see below).

Device list in MAX:

List of devices in Windows device manager:

I do have the last version of the NI-RIO driver - 13.1.

What am I missing? How can I make LabView recognize FPGA board.

Thanks!

MAX does recognize your FPGA board, one of them at least are there 2 on the system? The error says to use MAX to get the device name and you did it is "RIO0". The next question is what is the name of the device you are trying to open? Look at the code where the FPGA open function is being used.

I already changed FPGA target resource name to match the name of the device in MAX. It didn't help. What confuses me is that I see two devices in the Windows devide manager and only one in MAX.

I figured it out. You actually need to change the card alias in MAX to match FPGA target resource name instead of vice versa. That fixed the error.
