Target

In a terminal, run:

minicom /dev/ttyUSB0

Press enter when Minicom starts.

Sign on as root user (no password required).

Press enter when prompted for a password.

Run ifconfig. It should look something like this:

root@swi-mdm9x15:~# ifconfig

          inet addr:127.0.0.1  Mask:255.0.0.0

          RX bytes:32111 (31.3 KiB)  TX bytes:6725 (6.5 KiB)

Note that usb0 has an inet addr value. If it doesn't display an inet value, try rebooting the target and rerun ifconfig

Host

Open a new terminal on the host.

cd to your Legato directory.

Run bin/legs to set the Legato environment.

Run:

ifconfig usb0 <target ip addr> up

where the IP address subnet matches the target.

You may have to use sudo

local@LocalLinux:~$ sudo ifconfig usb0 192.168.1.20 up
[sudo] password for local:
local@LocalLinux:~$

Run ifconfig again, it should look something like this:
