My laptop can't upload code to robot.

Technical Programming
1

Hello, I am having some difficulties connecting my laptop to the robot to upload code. Here is some information:

  • My computer is a Asus Transformer Book T100 running Windows 8.1
  • Our team is using Eclipse to program in Java
  • Every other laptop on my team has been able to upload code, including other laptops running Windows 8.1
  • I have installed and reinstalled the NI Update Suite several times to get the MDNS software
  • Using the driver station software, I can connect to the roborio and enable, disable, look at joystick inputs, etc.
  • When I ping roborio-2220.local, I get back a result saying that I am connected
  • I don’t have the exact error with me right now, but it says something along the lines of Assertion Failed Boolean Test, and that MDNS connection failed
  • My firewall has been turned off

Is there something that I am missing? Thanks in advance for your help.

You’ve probably tried this already, but whenever I get that error, I usually power cycle the robot, which usually resolves the issue.

What is the error you get when deploying?

The roboRio is connected, the team number is set, and power cycling does not help, and when I try to upload and fail, other people are able to upload immediately after I fail

Are you uploading wired by USB, ethernet, or wirelessly?

Try resetting the team number in eclipse. It seems to think you are team 2200, not 2220.

Thats why the last few lines say roboRIO-2200.local and 10.22.0.2. It should be roboRIO-2220.local and 10.22.20.2.

Hi, when I go to my team number in preferences, it is 2220, but when I click restore defaults, it changes my number to 2200. I think that this is because when I first typed in my team number, I made a typo, and typed 2200 instead of 2220.

I tried changing my team number multiple times, and it always gives me an ArrayOutOfBoundsException, and it sometimes gives me an Unhandled event loop exception as well.

Is there a way I can change my default team to 2220?

Verify … your team number is set properly in Eclipse (Window->Preferences->WPILib Preferences).

I do not know any further than that. The best I can suggest is wipe and re-install the FRC update suite.
