02-Image Burnning

K2B currently provides two images: Android 12.0 and Ubuntu 22.04.

For Android 12.0, you can use a USB cable to flash the image onto the onboard eMMC.

For Ubuntu 22.04, you need to either flash the image onto an SD card and boot the system directly from the SD card or copy the system from the SD card to the eMMC.

1. Android Image Burnning

The development board comes with pre-installed images by default.

If you don't need to change the system, you can skip this step and start the system directly.

Tool Preparation

Downloading Software Tools

The software tools are divided into three parts: USB drivers, image burning tools, and system images.

All three parts can be downloaded from the cloud drive. Please contact customer service to obtain the cloud drive address.

Below is the directory structure corresponding to the tools in the cloud drive:

└── 2-System Image
    └── K2B
       	├── Android12 TV
       	├── Android12 Tablet
       	└── Ubuntu2204
└── 5-DevelopmentTools
    └── USB ImageBurnTool
    	└── PhoenixSuit.zip

Ways to Obtain System Images:

1. Download from the cloud drive.

2. Obtain through SDK compilation.

Image Descriptions:

The development board provides three images: Android 12 TV, Android 12 Tablet, and Ubuntu 20.04.

Both TV and Tablet are compiled from the Android 12.0 SDK, with only the desktop interface being different.

TV has a set-top box interface, while Tablet has a tablet interface. You can download them as needed.
