Spartan 3E, NI FPGA Tutorial Help Please

Not sure if this is a LabVIEW problem or a Xilinx problem

I am following the attached word document. When I run this example FPGA Shift.vi (listed in the document below), I get an error message (see attached .jpg file). I open the shift.vi through its project file, rather than the straight vi without the project file.

I am running Labview FPGA, and Xilinx on Windows 7. I installed the Xilinx with a driver for Vista, b/c nothing was listed for Windows 7 on Xilinx's website. I do have a machine capable of running XP (which xilinx had a driver for). Should I install all of this software onto the XP machine? Or do I have a different problem?

Is your Windows 7 install 64-bit or 32-bit?  The Spartan-3E support is currently only available for 32-bit Windows (note that it's the bitted-ness of the underlying OS that is important, not LV/FPGA since FPGA is only 32-bit).

If it's 32-bit, when the board is plugged in do you see an entry in Device Manager for a Xilinx Embedded Cable or some such device?

Its 64 bit.

I have a virtual machine running Windows XP 32 bit, was thinking about swapping it all over to that. I was wondering about if it was b/c I used a Vista driver for Win 7 on the Xilinx driver. But it sounds like it is more a 32 bit vs. 64 bit thing.

I was planning on trying that out if it was an OS thing, but it still may need to be, due to a bit thing. I will do the move over and see what happens and report back with results.

Thanks, BradM

Yes, unfortunately the Xilinx 64-bit driver doesn't like getting called from 32-bit code (just try running the 32-bit version of iMPACT on a 64-bit OS)

Also, the Spartan 3E XUP LV FPGA support installs a driver without the need to install the USB JTAG driver downloaded from Xilinx
