This document mainly introduces the usage of Ethernet on M2X . The first part of the document is about how to use it under Ubuntu, and the second part is about how to use it under Android.

Please make sure you use the latest image, if not please follow Upgrade The System to upgrade your system.

Open /boot/env.txt, add m2x-eth to overlay.

$ sudo vim /boot/env.txt
 
overlays=uart3 pwm_f i2c3 os08a10 --> overlays=uart3 pwm_f i2c3 os08a10 m2x-eth

Reboot to effect.

• before you use the M2x ethernet ,you should enable m2x ethernet by two method

• Enter Droid Settings→ More settings→ Network&Internet→ Ethernet,pitch on Ethernet Port as following

• About kbi usage ,you can refer kbi guide,set command as followimg

kvim3#kbi
kbi - Khadas Bootloader Instructions sub-system
 
Usage:
kbi [function] [mode] [write|read] <value>
 
kbi version - read version information
kbi usid - read usid information
kbi powerstate - read power on state
kbi poweroff - power off device
kbi ethmac - read ethernet mac address
kbi hwver - read board hardware version
 
kbi led [systemoff|systemon] w <off|on|breathe|heartbeat> - set blue led mode
kbi led [systemoff|systemon] r - read blue led mode
 
kbi forcereset [wol|gpio] w <0|1> - disable/enable force-reset
kbi forcereset [wol|gpio] r - read state of force-reset
[notice: the wol|gpio boot trigger must be enabled if you want to enable force-reset]
 
kbi bootmode w <emmc|spi> - set bootmode to emmc or spi
kbi bootmode r - read current bootmode
 
kbi portmode w <0|1> - set port as usb3.0 or pcie
kbi portmode r - read current port mode
kbi ext_ethernet w <0|1> - set ethernet from internal or m2x
kbi ext_ethernet r - read current ethernet mode
kbi tststatus r - read TST status
kbi tststatus clear - clear TST status
 
kbi forcebootsd
kbi wolreset
 
kbi ircode [customer1|customer2] w <ircode>
kbi ircode [customer1|customer2] r
kbi trigger [wol|rtc|ir|dcin|key|gpio] w <0|1> - disable/enable boot trigger
kbi trigger [wol|rtc|ir|dcin|key|gpio] r - read mode of a boot trigger
kvim3#kbi ext_ethernet w 1
[reg_31] 0x1d9a
[reg_16] 0x40
[reg_17] 0x7fbf
[reg_19] 0x0
[reg_31] 0x0
[reg_31] 0xd40
[reg_22] 0x0
[reg_31] 0x0
set m2x ethernet
kvim3#kbi ext_ethernet r
use m2x ethernet
kvim3#

• kbi ext_ethernet w 1 is to use m2x ethernet,kbi ext_ethernet w 0 is to use internal ethernet
