Verifying the Integration with a Host System
11.1.1.
Linux
The following descriptions are applicable for Unex software package only. For verifying
the integration of SOM-301(v2)/SOM-351 with a Linux host system, a user needs to follow
the steps below:
1
Check if the RNDIS driver has already been installed on the host system. If it has
not been installed yet, install the RNDIS driver for the host system. The driver
installation might include loading
rndis_host.ko
with
modprobe
command or
enabling
CONFIG_USB_NET_RNDIS_HOST
when compiling the Linux kernel. The detailed
instructions of installing the RNDIS driver are not included here because it may vary
from one distribution to another.
user@host:~$ lsmod | grep rndis
2
Check if the Unex device has been registered as a RNDIS device with a network
interface.
user@host:~$ dmesg | grep -i -C4 unex
3
Ping the RNDIS device IP of SOM-301(v2)/SOM-351 and check if it is alive.
user@host:~$ ping 192.168.1.3
4
Open a SSH terminal to SOM-301(v2)/SOM-351 and check if it works.
user@host:~$ ssh-keygen -R 192.168.1.3 ; ssh root@192.168.1.3
