# 3. Launch the application in your device

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
--- | ---
Port | Serial port where the device is connected
Baud rate | 115200
Datat bits | 8
Parity | None
Stop bits | 1
Flow control | None

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

Use the ifconfig command to get the device id:

    root@ccimx6ulsbc:~# ifconfig

In this example, the target IP address is 192.168.42.30.

Note 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@192.168.42.30:/home/root/
    The authenticity of host '192.168.42.30 (192.168.42.30)' can't be established.
    RSA key fingerprint is 46:91:93:11:31:d1:e0:b4:1e:3a:e9:fd:51:7f:bd:5a.
    Are you sure you want to continue connecting (yes/no)? yes
    Warning: Permanently added '192.168.42.30' (RSA) to the list of known hosts.
    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!
