1.2.2 Using Terminal Emulation

The ROM code console is only valid for host terminal connections via the serial port, as this is the sole method to access the ROM code console.

  1. To access the target console, users must download, install and configure a terminal emulation program on their host computers.
  2. Connect the host computer to the target device via an FTDI cable. Select the USB serial port in the emulator program settings based on the board design.
    • On Windows, identify the COM port by opening Device Manager and expanding the ports (COM and LPT). Locate the USB Serial Port entry and note the assigned COM port number. Configure the USB serial port in a terminal emulator with the following serial settings:
      • Baud Rate: 115200
      • Data Bits: 8
      • Parity: None
      • Stop Bits: 1
    • On Linux, PuTTY and Minicom can be installed from the command line:

      $ sudo apt-get install putty minicom

      Apply the serial settings listed above. To identify the USB serial port on Linux, run the following command and look for the relevant device entry in the output:

      $ dmesg | grep tty

  3. Check that RomBOOT appears on the terminal screen, confirming that the serial communication is established.
