This document mainly introduces WOL. You will learn how to enable WOL and wake up through WOL. The first part of the document describes the usage under Ubuntu, and the second part describes the usage under Android.

The Mac address is pasted onto the back of your SBC:

If the sticker has peeled-off, you can use following Terminal commands to get the MAC Address.

Type ifconfig on terminal.

$ ifconfig
eth0      Link encap:Ethernet  HWaddr 98:aa:fc:60:46:de
          inet addr:192.168.1.142  Bcast:192.168.1.255  Mask:255.255.255.0 
          inet6 addr: fe80::9aaa:fcff:fe60:46de/64 Scope: Link

HWaddr 98:aa:fc:60:46:de corresponds to your Ethernet MAC address.

By default Wake-On-LAN is disabled. So you’ll have to use the Khadas Bootloader Instructions (KBI)to enable it.

kvim2# kbi trigger wol w 1

If you want to check the WOL status, you can input:

kvim2# kbi trigger wol r
boot wol: enable

You can enable WOL via the Applications→Wake On LAN Setting.

Select WOL mode.

You can enable WOL in the Settings–>Khadas Settings–>WOL menu.

After doing the steps above, you can test the WOL function.

1. Connect with a LAN.
2. Power off.
3. Attempt to wake up, via a Ubuntu device on the same LAN.
   1. Install the wakeonlan tool.
      

      $ sudo apt-get install wakeonlan

   2. Wake up your VIM2 using it’s MAC Address.
      

      $ wakeonlan 98:aa:fc:60:46:de
