Error Code: -310606 - example "shift.lvproj" for Spartan 3E doesn't compile

[thru]

Hello !

I'm new to Labview so I tried to use a project that I found on the web (trafficlight) and it worked perfectly. But it was a little too complicated, so I took a project that I found in the project explorer Help : Shift.lvproj. I tried to compile the shift.vi but I always have the same error :

LabVIEW FPGA called another software component, and that component returned the following error:

Error Code: -310606

NI-COBS:  Access to an FPGA device address has timed out.

Please verify that the communication cable is plugged securely into your computer and target, and verify that the target has power. If the target has a removable clock, verify that the clock is present and running.

I think the cable and the clock are fine as I could run two other projects of my own.

My configuration : Labview 2011 SP1

NI DE FPGA Board plugged on NI ELVIS II+ (but I don't actually use ELVIS)

Thank you for your help !

This error comes from attempts to download and communicate with the VI on the actual FPGA, not from the compilation aspect. We can take a look and check to see if we can recreate the issue with the shipping example.  Otherwise, you could manually try to right-click on the FPGA bitfile buildspec and tell LabVIEW to recompile the bitfile manually and see if that fixes the problem or not.

I recompiled the bitfile manually as you suggested, and the compilation is successful. But when I try to run it on the FPGA I still get the same error message.

I am going to go ahead and try to reproduce the issue on my local machine, but in the meantime, the only thing that I could figure is if you had more than one board/device plugged into the system at a time (this includes any other Xilinx-based FPGA dev boards or one of their JTAG programming cables) and the system is picking the incorrect device to use to communicate.

I was unable to reproduce this error code running the LEDs\shift.lvproj example on my Spartan 3E with LV 2011sp1 + LV FPGA 2011sp1 + Spartan 3E support for 2011sp1 installer.
