Like the V5 System, the VEX ARM® Cortex®-based Microcontroller, VEXnet Joystick and VEXnet Key 2.0 each contain its own firmware. To update this firmware, you will need to download the VEXnet Firmware Upgrade Utility, the VEXnet Key 2.0 Firmware Upgrade Utility and the VEXnet Serial USB Driver.
The VEXnet Firmware Upgrade Utility overwrites the Master Code on the VEX ARM® Cortex®-based Microcontroller or a VEXnet Joystick to the latest version.
Note: By default, the Upgrade Utility will NOT overwrite any User Code in the Cortex Microcontroller with Default Driver Control Code. If you wish to revert your microcontroller to its default settings, make sure that "Default Code: ON" is properly selected.
