0.00 Volts - Code Not Downloading - Randomly Works?

[R.C.]

Hey CD,

Our 4 year programmer left and our cRio broke when some freshman yanked on the ethernet cord. So we got our cRio back and we were getting ready for some offseason competitions and trying to get a new programmer trained. In the process we added a motor and were trying to download some code.

The robot has been working fine and has always showed the voltage. The initial problem was setting up Windriver to download to the cRIO and we solved that by -> adding new connection -> VxWorks. But today we experienced a whole new problem. The Volts showed 0.00 and new robot code was not being updated. We turned off the bot and rebooted everything a few times.

Then by the end of the day, about an hour before we left the shop. I wanted to sneak the bot up to a freshman and surprise him. ALL OF A SUDDEN, the Voltage went back to the proper 12.67 and new code was downloaded.

I am not a programmer and this has been bugging me and I was wondering if anyone could explain what happened. The robot was not touched by any other member nor tampered with. Any Ideas?

Thanks,

-RC
