Re: Possible FLR Hacking?

Our team found similar issues both on and off field at FLR. We've traced control lockups to overuse of the cpu on the cRIO (or possibly the network stack), although we have no explanation as to why this would cause the code to fail without watchdogs tripping and all controls zeroing after a disable-enable cycle.

One other thing you might want to check out is the I/O board. We found that it occasionally goes crazy and crashes if the classmate is plugged into wall power (but never occurred on battery power).
