About KBI usage, you can refer KBI guide, enter the following commands.

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

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
