Troubleshooting

Communication using the USB A-to-A cable between ROBOTC and the Cortex is
Problem:
very slow, or not working.
Resolution: Verify each of the following options, and re-test your communication link before
moving on:
Is the USB A-to-A cable connecting the computer to your Cortex? The USB cable will provide
some power to the Cortex, powering some of its status lights. If not, try rebooting your system.
Is your robot also connected to and powered on by a charged battery?
Did you have the robot powered on before you connected it to the computer using the USB
A-to-A cable? The robot must first be connected to the computer using the USB A-to-A cable,
and then powered on with the battery.
Is VEX 2.0 Cortex selected as the Platform Type in ROBOTC?
Have you selected the correct Communication Port in the ROBOTC Preferences?
Have you downloaded the ROBOTC Firmware to the Cortex?
