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

          collisions:0 txqueuelen:1000
          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 and it's already configred, try rebooting the target and rerun ifconfig.

If USB isn't configured on a WP target, then delete /mnt/flash/ufs/etc and reboot:

# rm -rf /mnt/flash/ufs/etc
# reboot

Host

Open a new terminal on the host.

cd to your Legato directory.

Run bin/legs to set up your shell 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 192.168.2.20 up
[sudo] password for local:
local@LocalLinux:~$

Run ifconfig again, it should look something like this:
