2.1 Installing with the Fastboot Mode
Follow the steps below to install Android EVK image:
Step 1
Prepare the "fastboot tool" and install the "VIA USB driver" into your Windows 10 host machine.
To get the "fastboot tool" for Windows, please refer to the "SDK Plaorm Tools release notes" chapter on the
Android developer website hps://developer.android.com/studio/releases/plaorm-tools.
To install the "VIA USB driver", right-click "android_winusb" and select "Install".
Then click "Install" when the installer opens.
When the installer nishes, it will show a conrmaon message "The operaon completed successfully".
Step 2
Connect the Windows 10 host machine and the VIA ARTiGO A3000 through the Micro USB 2.0 port using the
Micro USB cable.

Step 3
Plug in the AC-to-DC power adapter to power on the VIA ARTiGO A3000 .
If the EVK image is not installed, the VIA ARTiGO A3000 will stop at "fastboot: processing commands" as shown
in the debug console below. Proceed to step 4 directly.
Fastboot Mode
If the EVK image is already installed, use the following command to enter the Fastboot Mode on your Windows
10 host machine.
D:\platform-tools>adb shell reboot bootloader
Note:
Aer powering on the VIA ARTiGO A3000, make sure the Windows 10 host machine detects it as an ADB device.
Step 4
Extract the VIA_ARTiGO_A3000_Android_12.0_EVK.zip le on your Windows 10 host machine.
To install the image, use the following command:
D:\VIA_ARTiGO A3000_Android_12.0_EVK>set PATH=D:\platform-tools;%PATH%
D:\VIA_ARTiGO A3000_Android_12.0_EVK>viaash.exe --android
