USB
The WP85 module on a mangOH board is pre-configured to use the USB cable.
Connect serial, USB, and power cables.
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:~# ifconfiglo Link encap:Local Loopbackinet addr:127.0.0.1 Mask:255.0.0.0inet6 addr: ::1/128 Scope:HostUP LOOPBACK RUNNING MTU:16436 Metric:1RX packets:0 errors:0 dropped:0 overruns:0 frame:0TX packets:0 errors:0 dropped:0 overruns:0 carrier:0collisions:0 txqueuelen:0RX bytes:0 (0.0 B) TX bytes:0 (0.0 B)usb0 Link encap:Ethernet HWaddr 32:E4:5E:6F:C4:3Cinet addr:192.168.2.2 Bcast:192.168.2.255 Mask:255.255.255.0inet6 addr: fe80::30e4:5eff:fe6f:c43c/64 Scope:LinkUP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1RX packets:197 errors:0 dropped:0 overruns:0 frame:0TX packets:57 errors:0 dropped:0 overruns:0 carrier:0collisions:0 txqueuelen:1000RX 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 192.168.2.20 up [sudo] password for local: local@LocalLinux:~$
Run ifconfig
again, it should look something like this:

Ping target to host and vice versa to check everything is working.
