Connect to USB ECM (Linux)

This section only applies to Linux host machines.

rity-demo-image includes a SSH server and is configured to expose an SSH port over USB CDC-ECM device by default. You can connect to USB0 port directly from a Linux host.

For Windows users, please refer to this page to re-configure the USB as an RNDIS device before continuing.

Connecting to USB CDC-ECM

Simply plug the USB0 port of your board to your Linux host machine.

  • On AIoT-i350-EVK, connect to the micro-USB port labeled as USB0

  • On i1200 Demo Board, connect to the USB-C port labeled as CON4

Connecting by using the board IP

The USB CDC-ECM interface in rity-demo-image is configured with the following static IP:

192.168.96.1

You can connect to the board using the following command:

ssh root@192.168.96.1
root@i350-evk:~#

You can also use scp programs to copy files to the board:

scp host-file.txt root@192.168.96.1:/path/to/target/directory

Connecting by using mDNS

AIoT Yocto also includes a mDNS server avahi daemon to provide device discovery.

The host name of the board is in the form <machine>.local, where <machine> is the value of MACHINE variable that was used to build the SDK.

For instance you can connect to the i350-evk board with the host name i350-evk.local by using the following command:

ssh root@i350-evk.local
root@i350-evk:~#

Hint

It is recommended to modify /etc/avahi/avahi-daemon.conf and set host-name to change the host name of the board to something unique if there are multiple boards of the same model connected to the same network. And run systemctl restart avahi-daemon to take effect.
