"Robot Code" won't turn green, but no errors are displayed

[YoshiCity]

The "Robot Code" light turns red if the code stops running, for example if there is an error that causes the code to restart in tele-op, the robot will disable and the light will turn red until the code has done its thing. The only times the "Robot Code" light has never turned green for me has been when there is such an error in a section of the code that runs immediately (Robot Init). Check out that bit of code and make sure that everything that you're initializing actually exists and is in the right port.
Good luck
