Arrowhead,

Team 4243 has been having the exact same problem. Out of the box Simple Robot and Default Robot templates work out of the box on an 8-slot cRIO but fails with timeout errors on a 4-slot cRIO.

This is our second year and the same problem annihilated our rookie performance last year. At that time we managed to disable the timeouts but our code effectively executed at 3 Hz instead of 50 Hz resulting in pretty embarrassing performance.

Fortunately we had an 8-slot cRIO Team 342 had lent us to get some programming knowledge before last year's build season started. And, thanks to this thread, I changed out our 4-slot cRIO for the 8-slot cRIO, and the Simple Robot Template compiled and executed flawlessly!!! I repeated the experience with the Default Robot template. What a relief!!

Given all the related threads on MotorSafetyHelper timeout messages, I think it is clear WPILib is not fully compatible with the 4-slot cRIO. Not last year and not this year.
