Console Access - mangOH Red Manual

E: Console Access
If you have two USB ports on your dev machine, you can use one of them to display the mangOH Red's diagnostic
messages when the device boots, when certain commands are run, etc.
To set up a window to display diagnostic messages:
1. Use a micro-USB cable to connect the mangOH Red's CONSOLE USB port to a USB port on the dev
machine.
2. Open a terminal window on the dev machine—This window will display the target's console messages (kernel
messages, warnings, etc.).
Note:
Depending on your desktop, a terminal window may be opened using a keyboard shortcut (e.g. Ctrl+Alt+T for
the Ubuntu Unity desktop), or an icon or menu item.
3. Connect to the target's Linux console as follows:
a. In the terminal window, enter the following command to install the minicom application on your dev
machine (if it is not already there):
$ sudo apt-get install -y minicom
Note:
'sudo' tells the dev machine to run the command as the 'superuser'. Each time you use sudo, you must
enter your dev machine's password to continue.
b. Connect to the target's Linux console via the USB serial port (which enumerated when you connected the
CONSOLE USB connector to the dev machine):
$ minicom -D /dev/ttyUSB0
A welcome message appears, and the window will show console messages when the mangOH Red
powers on in the next step.
