706 had the curse of all curses

[petet4]

A little more detail on the cRio issue. I'm the software mentor for team 706 and in the process of trying to debug the intermittent cRio mini resets, which I now understand as a 2nd watchdog within the cRio. We created a new project and created a telop loop consisting of 2 lines. Where shftin is a solenoid output. When telemode was enabled within a couple of minutes the solenoid LED would intermittently turn off for about .25sec.

void OperatorControl(void)
{

while (IsOperatorControl())
{
shiftin.Set(true);
Wait (0.01);
}
}

There was no predicable rate it would go out. Sometimes it would run for minutes with no issues and sometimes it would go out several times with 10-20 seconds.

One thing that would make things better is to use a different classmate but the problem never went away. The first classmate which showed the problem most often was running 23 processes and about 0.85% network usage and ~25% CPU usage. The 2nd classmate when worked better had 47 processes running with about the same network and CPU usage as the first.

The software on the classmate was uninstalled and re-installed which did make any difference. The were many other things tried. When we get robot back I plan to analyze the network traffic between the cRio and the driver station to get to the root cause of this issue.
