* 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. You need to update the kernel to at least version 4.4.143-46-rockchip.

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. You need to update the kernel to at least version 4.4.143-46-rockchip.

  • Stop conflicting services

So far, Type-C OTG port only supports one Gadget function. To use use USB net, here need to stop 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 ROCK CM3 IO to PC with a USB to USB A cable.
  • Install kernel module on ROCK CM3 IO 
root@radxa-cm3-io:modprobe g_ether

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

Remind

If you can't ping the PC or rock pi.You should check your gateway.

Here's how to check for hardware problems.If it is successful, then the hardware is ok.

In Rock CM3 IO 

root@radxa-cm3-io:~# route add -net 10.0.1.0/24 gw 10.0.1.1 dev usb0
root@radxa-cm3-io:~# iperf3 -s

In PC 

radxa@x86_64_pc:~$ radxa@x86_64_pc:~$ route add -net 10.0.1.0/24 gw 10.0.1.2 dev usb0
radxa@x86_64_pc:~$ iperf3 -c 10.0.1.1
