2. Image Installaon
This secon explains the setup requirements for boong from the eMMC.
The precompiled images are provided in the "Firmware" folder.
2.1 Installing with the Fastboot Mode
The rst step is to 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 on the mouse buon to install the "android_winusb". When nished,
it will show "The operaon completed successfully".
Then connect the Windows 10 host machine and the VIA IVT01 through the USB 2.0 Type-A port using the
Male USB Type-A to Male USB Type-A cable.
USB 2.0 Type-A port diagram
Plug in the AC-to-DC power adapter to power on the VIA IVT01.
The VIA IVT01 will stop at "fastboot: processing commands" as shown in the debug console below.
Fastboot Mode
Note:
Make sure the Windows 10 host machine detects the VIA IVT01 as an Android device.

3. Hardware Funcons
This secon explains how to enable and test the hardware funcons precompiled in the Android 10.0 EVK
including using the debug console.
3.1 Using the Debug Console
Insert one plug connector of the 3-pin cable into the port labeled "CONSOLE" on the VIA IVT01.
Insert the other plug connector of the 3-pin cable into the 3-pin port located on the USB to UART debug board.
Connect the Windows 10 host machine through the Micro USB 2.0 port on the USB to UART debug board using
the Micro USB cable.
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".
Next, power on the VIA IVT01 to iniate the boot process.
When the boot process has completed, 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
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 Camera
Click the "Camera" APK on the Android desktop to verify the camera funcon.
If the CSI camera is connected correctly, but there is no "Camera" APK on the Android desktop, go to "Sengs
-> System -> Advanced -> Reset opons" and press "Erase all data (factory reset)" to restart the system.
The “Camera” APK will be generated aer the system is rebooted.

3.6 MTK NeuroPilot AI APU Hardware Acceleraon
We recommend to install the third-party APK "image_classicaon_MobileNet_app-debug.apk" for
vericaon.
To enlarge the logcat buer to 64MB, use the following command:
console:/ # logcat -G 64M
To enable the NeuroPilot relave log for geng the NN relave log in logcat, use the following command:
console:/ # su
console:/ # setprop debug.nn.vlog 1
console:/ # setprop debug.neuropilot.apu_nn.log 1
console:/ # setprop debug.neuropilot.gpu_nn.log 1
console:/ # setprop debug.neuropilot.arm_nn.log 1
Run the third-party APK "image_classicaon_MobileNet_app-debug.apk".
Then choose "Model: Quanzed" and "Device: NNAPI".
