Example - USB Serial Console


This example connects the USB Serial Console port to a host system, powers up the development kit, and provides basic verification that the development kit is working.


  • A micro USB Cable
  • A host system with a USB connection. (Windows or Linux PC)
  • A terminal monitor program such as PuTTY or teraterm.


  • For windows, you will need to download the Silicon Labs virtual COM port driver for the CP2105 Dual UART to USB bridge chip. This interface provides 2 COM ports, one for the Cortex A-53 complex (linux console, the "standard COM port"), and a second for the MCU console UART (the "enhanced COM port").
  • Plugin the USB cable into the USB-UART connector on the development board and the host system.

  • Plugin the power cable for the development board.
  • Turn the power on
  • Connect Putty to the serial port. You will need to determine which serial port this is on your host PC (Windows or Linux). Something like /dev/ttySx, or, for windows "Silicon Labs Dual CP2105 USB to UART Bridge: Standard COM Port (COM5)".
    • Specify the speed as 115200
  • You should see output such as:
[   29.821930] Initializing XFRM netlink socket
[   32.878059] bridge: filtering via arp/ip/ip6tables is no longer available by default. Update your scripts to load br_netfilter if you need this.
[   32.899139] Bridge firewalling registered

mitysom-am62x login: root
  • Login with a user id of 'root'. There is no password.


This completes this initial hands-on example. You now know that the development kit has basic functionality and can be logged into.
