Requirements

  • ROCK CM3 IO
  • USB 3.0 or 2.0 male type A to male type A cable
  • Host PC running Linux OS

Software preparation

  • Kernel version

USB gadget driver must be enabled to configure usb net.

  • Stop conflicting services

So far, Type-C OTG port only supports one Gadget function. To use USB net, need to disable rockchip-adbd service. 

root@radxa-cm3-io:~# systemctl stop rockchip-adbd
root@radxa-cm3-io:~# systemctl disable rockchip-adbd
root@radxa-cm3-io:~# reboot

Load kernel module

  • Connect the Radxa CM3 IO to PC with one microUSB to Type-A cable.
  • Install kernel module on Radxa CM3 IO 
root@radxa-cm3-io:~# modprobe g_ether

root@radxa-cm3-io:~# dmesg -c

[   26.154634] g_ether gadget: high-speed config #1: CDC Ethernet (ECM)

Bring up the usb0 device

root@radxa-cm3-io:~# ifconfig usb0 up

Setup USB Network

On ROCK Pi S. 

root@radxa-cm3-io::~# IP=10.0.1.1
root@radxa-cm3-io::~# HOST_IP=10.0.1.2
root@radxa-cm3-io::~# ifconfig usb0 $IP netmask 255.255.255.0
root@radxa-cm3-io::~# route

On host PC 

radxa@x86_64_pc:~$ HOST_IP=10.0.1.2
radxa@x86_64_pc:~$ sudo ifconfig usb0 $HOST_IP netmask 255.255.255.0

Test the network, on Radxa CM3 IO 

root@radxa-cm3-io::~# ping $HOST_IP
