cRIO user LED does not seem to work!!

The LED shows up as a digital line output in my LV project, and shows up in the FPGA I/O node (along with all the other I/O I have configured), but I can't seem to get it to do anything. I've been able to successfully compile a variety of different VIs targeted to the FPGA and run them, but I cannot get the FPGA user LED to turn on-off.

I'm using LV 8.0.1 on Windows XP. I've tried 3 different cRIO 9004 controllers, and all of them seem to behave identically. I just created a VI that measures the chassis temp and sets the LED status (on/off alternating) every 0.5 seconds. The chassis temp measures just fine. The LED never changes. I wired the error out (FPGA I/O node) to an indicator, No error.

What am I doing wrong? Am I under the mistaken impression that I can control the On/Off status of the user LED?

Thanks,
The Dog

The "User LED" on the controller can only be written to using LabVIEW RT.  The "FPGA LED" channel is currently only supported on the cRIO-9052 controller.  That controller has both the "User LED" and "FPGA LED" on it's face.  The cRIO-9002/4 controllers do not have the "FPGA LED".   Since the chassis can be connected to any cRIO controller, the FPGA LED channel is always an available LabVIEW FPGA I/O resource.

According to the manual, this function is available for the cRIO-9012, but I am not able to get it to work.  I have a control wired to the FPGA LED I/O node but nothing happens when I change the value of the control
Nevermind, just found my problem...
