4.1. Startup

When connecting power to Armadillo-IoT G3, the start mode changes depending on the slide switch on the USB serial converter. For details, refer to 「Slide Switch Configuration」. This section shows an example when maintenance mode is selected. When auto boot mode is selected, the startup completes without requiring any input.

Debian GNU/Linux 9 armadillo ttymxc4

armadillo login:

図4.2 Boot Log

The startup status of Armadillo-IoT can be checked with the user LEDs. Therefore, the startup status of Linux can be confirmed even if turning on power without connecting the USB serial converter to Armadillo-IoT.

Boot State	User LED1	User LED2	User LED3	User LED4
Bootloader is in maintenance mode	On	Off	Off	Off
While Linux is booting	On	On	Off	Off
Once Linux has completed booting	On	Off	Off	Off

For the location of the user LEDs, see 図5.40「User LEDs Location」.

4.2. Login

The login prompt will be displayed once the boot has completed. The usernames shown in 表4.1「Serial Console Login Username and Password」 can be used to login.

表4.1 Serial Console Login Username and Password

Username	Password	Permissions
root	root	root user
atmark	atmark	general user

When connecting the device for the first time, please make sure to change the default password by following the procedure below.

Change the default password.

[armadillo ~]# passwd
Enter new UNIX password: # Enter new password here
Retype new UNIX password: # Re-enter

Change the default password.

[armadillo ~]$ passwd
Enter new UNIX password: # Enter new password here
Retype new UNIX password: # Re-enter
[armadillo ~]$


	With Armadillo-IoT G3 being a device that can be connected to a network, the security risk will be extremely high if used with the default password. It is strongly recommended to change the password to one with high security strength, and then manage the password appropriately thereafter.

4.3. Managing Debian Users

Creating a User

Here we create a user named guest as an example.

[armadillo ~]# adduser guest
Adding user `[user_name]' ...
Adding new group `guest' (1001) ...
Adding new user `guest' (1001) with group `guest' ...
Creating home directory `/home/guest' ...
Copying files from `/etc/skel' ...
Enter new UNIX password: # Enter password here
Retype new UNIX password: # Re-enter
passwd: password updated successfully
Changing the user information for guest
Enter the new value, or press ENTER for the default
        Full Name []: # press ENTER
        Room Number []: # press ENTER
        Work Phone []: # press ENTER
        Home Phone []: # press ENTER
        Other []: # press ENTER
Is the information correct? [Y/n] # press ENTER

Changing the Password

Here we change the password of the guest user as an example.

[armadillo ~]# passwd guest
Enter new UNIX password: # Enter new password here
Retype new UNIX password: # Re-enter

Permitting Use of sudo
Here we give permission to use sudo to the guest user as an example. For details on how to use vi, please refer to 「Using the vi Editor」.
```
[armadillo ~]# visudo
...
# User privilege specification
root    ALL=(ALL:ALL) ALL
guest   ALL=(ALL:ALL) ALL # Add this line
...
```
Deleting a User
Here we delete the guest user as an example.
```
[armadillo ~]# userdel guest
```
To delete the home directory at the same time, use the "r" option.
[armadillo ~]# userdel -r guest

4.4. Shutdown

To perform a safe shutdown, execute the command shown below, wait until the "System halted." message is displayed and then disconnect the power supply.
