How To Setup PCIe/USB3.0 Port

Khadas VIM3 contains a data switch to switch the “combo interface” between PCIe and USB 3.0. The default mode is USB 3.0.
You can find the block below.

There are three ways to setup the PCIe/USB3.0 port:

• Use KBI to setup the port
• Setup the port using the Android UI
• Setup the port using the Android/Ubuntu command line

Use KBI to setup the PCIe/USB3.0 port

You need to setup the serial debug tool and enter the u-boot command line.

• Initialize the KBI:

kvim3#kbi init

• Check current port mode:

kvim3#kbi portmode r
port mode is USB3.0

The default mode is USB-3.0.

• Change mode to PCIe:

kvim3#kbi portmode  w 1
set port mode to :PCIE

• Change mode to USB 3.0:

kvim3#kbi portmode w 0
set port mode to :USB3.0

Poweroff the system to bring changes into effect:

kvim3#kbi poweroff 
do_kbi_poweroff

Then press the POWER KEY to reboot the system.

Use Android UI to setup the PCIe/USB3.0 port

You’ll need to navigate to “Device Preferences” using an IR remote, mouse or attached keyboard.

Reboot the system to bring changes into effect.
