How to determine COM port

This section describes the steps necessary to determine the debug COM port number of your NXP hardware development platform.

  1. Linux: The serial port can be determined by running the following command after the USB Serial is connected to the host:

    $ dmesg | grep "ttyUSB"
                    [503175.307873] usb 3-12: cp210x converter now attached to ttyUSB0
                    [503175.309372] usb 3-12: cp210x converter now attached to ttyUSB1

  2. Windows: To determine the COM port open Device Manager in the Windows operating system. Click on the Start menu and type Device Manager in the search bar.
