Build Successful is displayed but robot code stays red

Technical Programming
#1

I will explain all details after this paragraph, but this is the most baffling thing: I have tested two projects, neither of which work on this year’s robot. However, both work on last year’s robot. So it can’t be the code, right? Despite that:

Everything on the laptop is updated (the IDE, frc update suite, driver station, all libraries used, gradlerio, etc.). The rio was flashed with the latest firmware earlier today. I am using a USB connection straight from the rio to the laptop, which has been tested to work on another robot. I am using gradlerio on both projects, which both work on last year’s robot.

I don’t know what else it could be, aside form the roborio. But it was just flashed. Anyone have any suggestions?

#2

Did you update both the firmware and the image on the roboRIO?

#3

Are there any errors or prints in the console? Make sure you add prints and warnings on the driver station.

#4

Yes, with the latest firmware.

#5

No errors.

#6

I’m having the same problem - the Riolog in Eclipse says “Console output requires a Driver Station to be connected to the robot.”
Again, the code worked before and now suddenly doesn’t.

#7

Do you have the console output disabled on the rio? Re- enabling it might let you se the output in eclipse,
Do you get a green when for robot code when you download , then it goes red?
It so, you might be trying to assign an IO port multiple times . We ran into a similar problem assigning the serial port to our sonar when console output was enabled . Green robot code until we enabled them suddenly red .

#8

The next thing I would recommend is to go back to eclipse and a new-other-example-“tank drive” project. That should work with any rio and any lan/wifi/usb connection (even if its the wrong pwm-ports…), if that succeeds then you start to debug your own projects from the top (missing libs… missing .ini files…).

#9

This is somewhat of a long shot, but make sure your driver station has the correct team number. I know my team has definitely messed that up and not understood why code wasn’t working. It won’t connect if the team number is wrong in the DS.
