If you use wireshark or another network protocol analyzer and only see UDP packets then it will fail. The actual transfer seemed like FTP. After verifying that that one accepted and worked, I did the following the stubborn one.

I turned the cRio off. I then switched it to safe mode. You can't image in safe mode, but you can reformat it. So I reformatted it, and once it completed I powered it down. Switch it back to normal mode, then power it up. I then reimaged it normally. I'm not sure, but it might be worth noting that the time after the reformat I forgot to set a team number, so it was on 0. I don't think it matters but it is exactly what I did. I then reimaged it with the correct team number.

Before you do these steps remember, if the cRio doesn't take the image after the reformat then it will not run your code. If possible have a computer read the console output, sometimes you find a really helpful clue.
simpsonboy77,

I appreciate your quick response. Are you, by any chance, using CAN this year? Another team member of mine just emailed another post. http://www.chiefdelphi.com/forums/sh...light=cRio+v20 post #5. It appears that either CAN plugin, 2CAN or BlackJag will cause the cRio to not be able to flash correctly. I will try re-flashing with the reference to the BlackJagPlugin removed and see if that works, and then try your method if it does not. Again, thanks for the help. I'll try to repost with the solution (assuming we end up with one).

- Bryce

P.S. The plugin would make sense because we have not re-flashed since adding the plugin reference.
