Driver Station Loosing Communication

[stingray27]

Hey ChiefDelphi,

We are trying to run code on to a 8 slot cRio. We have had no issues until today. What happens is we are able to deploy code to the cRio perfectly fine and like normal (we are using labview) and the robot will start up. We then can enable or disable the robot but we are hitting huge issues with communication. The robot code and communication lights on the driver station all of the sudden will go red and then come back on. This will happen around once every 2 seconds but it is super inconsistent. We have tried looking for shorts, unplugging the analog and digital modules in the cRio, etc. Sometimes we think something fixes it and then it will occur again. As for code, we don't see an issue as we time all of our vis and they all are running perfectly fine in terms of processing speed.

Here is the message in the dialog box on the driver station:
FRC: The Driver Station has lost communication with the robot.
Warning <Code> 44003 occurred at Driver Station
OR
FRC: No robot code is currently running.
Warning <Code> 44002 occurred at Ping Results: link-bad, DS radio(.4)-bad, robot radio(.1)-bad, cRIO(.2)-bad, FMS-bad Driver Station

Any suggestions? Thanks.
