Follow these steps to execute the application in your device:

  1. Open a serial connection using any terminal program such as Tera Term, Minicom, Coolterm, or HyperTerminal. The examples in this documentation use Minicom to work with the device command line.

    Use the following settings:

    Parameter Value


    Serial port where the device is connected

    Baud rate


    Data bits




    Stop bits


    Flow control


  2. Log in to the device. The default login user is root without password. See How to find the IP of your device.

    Your device and your host machine must be in the same network.
  3. Transfer the application to your device using SCP in your host computer. If it is the first connection, you are prompted to continue. In this case, type yes and press Enter.

    ~$ scp hello-world root@

    Are you sure you want to continue connecting (yes/no)? yes

    hello-world                                                                                       100%   12KB  11.8KB/s   00:00
  4. In the device terminal, launch the application you have just transferred. The message "Hello world!" is printed 10 times, one every second.

    ~# /home/root/hello-world
    1 - Hello world!
    2 - Hello world!
    3 - Hello world!
    4 - Hello world!
    5 - Hello world!
    6 - Hello world!
    7 - Hello world!
    8 - Hello world!
    9 - Hello world!
    10 - Hello world!

How to find the IP of your device

You can find the IP of your device with the ifconfig command.

~# ifconfig eth0
eth0      Link encap:Ethernet  HWaddr 00:40:9D:98:A6:37
          inet addr:  Bcast:  Mask:
          inet6 addr: fe80::211:22ff:fe33:2211%lo/64 Scope:Link
          RX packets:1071204 errors:0 dropped:0 overruns:0 frame:0
          TX packets:81475 errors:0 dropped:0 overruns:0 carrier:0
          collisions:0 txqueuelen:1000
          RX bytes:119890110 (114.3 MiB)  TX bytes:16714042 (15.9 MiB)

In this example, the target IP address is
