If you only see "Automatic Selection" when selecting the communications port to download firmware to the Cortex, what should you do?

When seeing "Automatic Selection" in the communications port selection while attempting to download firmware to the Cortex, disconnecting and reconnecting the USB A-to-A cable is the appropriate action to take. This practice effectively resets the connection between the computer and the Cortex, which can resolve issues with communication that may be preventing the port from being recognized correctly.

The "Automatic Selection" status indicates that the computer is unable to identify the specific communication port due to a potential transient error. By reconnecting the USB cable, you allow the system to re-establish the connection and potentially recognize the device correctly.

This troubleshooting step often resolves common connectivity issues by refreshing the link, restoring proper communication between the devices, and making the necessary ports available for firmware downloads. It’s a straightforward solution that can eliminate common hiccups in the electronic communication process.
