PDP CAN Connection Problems

[FireAmpersand]

We've had no problems with the PDP until yesterday. We uploaded some code with incorrect CAN ids for our jags, which caused the code to crash immediately (fair enough), but it also caused the COMM and STAT lights on the PDP to start blinking red.

We shut the system down, fixed the code, and rebooted and reuploaded. Now the robot works fine, except that the lights on the PDP still are blinking red, which is unsettling.

We have fixed red-blinking-lights on the PDP before by clearing sticky faults in the RoboRIO's WebDash, but now the PDP doesn't even detect the PDP in the CAN chain, though it does detect the jags and the PCM.

Any thoughts?
