2. Image Installaon
This secon explains the setup requirements for installing the Android evaluaon image on the VIA SOM-3000
starter kit.
The precompiled images are provided in the "Firmware" folder.
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 SOM-3000 starter kit 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 SOM-3000 starter kit.
If the EVK image is not installed, the VIA SOM-3000 starter kit 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 SOM-3000 starter kit, make sure the Windows 10 host machine detects it as an ADB
device.
Step 4
Extract the VIA_SOM-3000-STK_Android_12.0_EVK.zip le on your Windows 10 host machine.
To install the image, use the following command:
D:\VIA_SOM-3000-STK_Android_12.0_EVK>set PATH=D:\platform-tools;%PATH%

3. Hardware Funcons
This secon explains how to enable and test the hardware funcons precompiled in the VIA SOM-3000-STK
Android 12.0 EVK.
3.1 Using the Debug Console
Follow the steps below to use the debug console:
Step 1
Insert one plug connector of the 4-pin FFC cable into the J3 port labeled "UART0" on the VIA SOM-3000
module, ensuring that the gold nger of the FFC cable faces down.
UART0 Port

Step 2
Insert the other plug connector of the 4-pin FFC cable into the 4-pin FFC port located on the USB to UART
debug board, ensuring that the gold nger of the FFC cable faces down.
FCC Port
Step 3
Connect the Windows 10 host machine and the USB to UART debug board through the Micro USB 2.0 port
using the Micro USB cable.
Step 4
Use a serial port communicaon program such as PuTTY or Tera Term to connect the debug console. Set the
console Baud Rate to "921600".
Step 5
Power on the VIA SOM-3000 starter kit to iniate the boot process.
Step 6
When the VIA SOM-3000 starter kit has completed boong, log in to the debug console.
3.2 Changing the Kernel Debug Level
To disable the kernel messages, modify the debug level using the following command:
console:/ # su
console:/ # echo 3 > /proc/sys/kernel/printk
3.3 Checking the BSP Version

8
VIA SOM-3000-STK Android 12.0 EVK Quick Start Guide
To check the BSP version, use the following command:
console:/ # cat /proc/version
3.4 DVFS
To verify the DVFS (Dynamic Voltage Frequency Scaling) funcon and list all the supported features, use the
following commands:
console:/ # ls -l /sys/devices/system/cpu/cpu0/cpufreq/

3.5 Display
There is no need to set the display device. If you connect an HDMI display, HDMI output will be automacally
enabled aer boong. If you connect an LCD panel, LCD panel output will be automacally enabled aer
boong.
3.6 Camera
If a desired CSI camera module was connected correctly to the VIA SOM-3000 starter kit before boong the
VIA SOM-3000 starter kit, a "Camera" APK can be found on the Android desktop. Click to open it and test the
camera funcons.
If the CSI camera module was connected correctly before boong the VIA SOM-3000 starter kit, but there is no
"Camera" APK on the Android desktop, navigate to "Sengs > System > Reset opons" and click "Erase all data

9
VIA SOM-3000-STK Android 12.0 EVK Quick Start Guide
(factory reset)" to reboot. The "Camera" APK will be generated aer the system reboots.
3.7 MTK NeuroPilot AI APU Hardware Acceleraon
We recommend running the "PoseDetector_Image.apk" sample program for tesng MTK NeuroPilot AI APU
hardware acceleraon. To install the program, follow the steps below:
1. Copy the "PoseDetector_Image.apk" le to a USB drive and connect the USB drive to the VIA SOM-3000
starter kit.
2. Next, navigate to "Files" and click on the USB drive's name to nd "PoseDetector_Image.apk" as shown
below. Double-click the program
3. When the program opens, it will display a dialog box as shown below. Click "Connue" to conrm.
4. Aer installaon, double-click "PoseDetector" to run the program.

10
VIA SOM-3000-STK Android 12.0 EVK Quick Start Guide
5. Check the Pose Detecon inference me on the boom le corner of the program:
−If the inference me is less than 200 ms, MTK NeuroPilot AI APU hardware acceleraon is enabled
and running correctly.
−If the inference me is greater than 200 ms, MTK NeuroPilot AI APU hardware acceleraon is
disabled.
