There was a specific WPILib timing function that was not receiving the right inputs from the FMS (the GetMatchTime function). Most cases I've seen that use that function use it during teleop to detect the end of the match, which was correct. However, this has been fixed in Cheesy Arena, so Beach Blitz and Capital City Classic should not have this issue.

Regarding the e-stop issue, we are still working with FIRST to try and detect the cause and institute a fix. Our plan during Beach Blitz if we see it is to immediately replay the match, as the issue pops up right at the beginning of the match.

At this time, the e-stop issue appears to be manifestation of the DS being in "FMS Lite" mode and not having the space bar estop disabled. Until we have a solid answer as to the root cause, and/or a fix for the issue, CCC will be implementing the same workaround we used at Chezy Champs. Specifically, teams will be requested to restart the DS software before each match. In addition, we will also take the approach that Beach Blitz is using of immediately restarting a match where the estop issue pops up.
These are minor adjustments, but for the integrity of the tournament, we feel these measures are necessary.

BTW, if you were not aware, the new binaries for Cheesy Arena were posted 2 days ago. They include all updates from the start of Chezy Champs until now.

Close... We still need to figure out how to pull the updated configs off the router used at CC which open up the ports used by smart dashboard and others.

On behalf of Team 254, I wanted to thank everybody for your patience with the FMS at Chezy Champs. The e-stop issue, which was experienced by teams at Chezy Champs (using Cheesy Arena) and at SCRRF Fall Classic (using FIRST FMS Lite) seems to be a bug in the driver station software, and is being investigated by National Instruments. At Chezy Champs, we believe that we replayed the matches with e-stop issues where the head referee determined that the outcome of the match was affected. I do not believe that the issue appeared during the elimination matches. For future off-seasons, we recommend that you have each team restart the driver station app prior to each match, as described above by Bill. Our sincere apologies go out to any teams whose matches were missed.

When setting up the field for Chezy Champs, several code changes were made to Cheesy Arena and to the configuration of the advanced networking hardware. None of these changes were in regards to the e-stop issue, which we believe is a driver station bug affecting FMS Lite as well as Cheesy Arena. These changes can be downloaded as a released binary on Github. For Beach Blitz and CCC, which are using the Chezy Champs hardware, the updated networking configuration is already on the equipment.

As a reminder, if you have any feedback about the event, we'd love to hear it on this form. From the feedback thus far, it sounds like most teams' experiences were positive, and we've taken some notes on things to improve for next year. In particular, we got very positive feedback for "254 losing", and will be sure to schedule that in next year . We hope that we will see many of the same teams back next year and that this event continues to grow and improve.

Router or Switch? The only router I am aware of being used was to provide access to the Internet to allow uploads/Downloads to/from BlueAlliance and maybe the video stream.

If you are referring to the Cisco 3550 switch, getting the config off is fairly straight forward, as long as you have physical possession of it .
