2. Compile Source

2.1 Android 14

❶ Extract Source Code

tar xvf rk3576_android14_sdk-20260528.tar.gz
cd rk3576_android14_sdk

❷ Configuration

source build/envsetup.sh
lunch boardcon_compact3576-userdebug

❸ Compile

./build.sh -AUCKu

After the command is completed, the image files will be generated in the rockdev/Image-boardcon_compact3576 directory.

Step 1, Compile U-Boot

./build.sh -U

Step 2, Compile Kernel

./build.sh -K

Step 3, Compile Android

./build.sh -A

2.2 Android 16

The Rockchip Android 16.0 SSI SDK provides only the AOSP codebase. After compilation, it generates only system-related images (system.img, system_ext.img, product.img), which are identical to Google’s GSI images. Other code modules must be compiled using the Android 14 SDK. Therefore, the Rockchip Android 16.0 SSI SDK must be used in conjunction with the Android 14 SDK. The architecture diagram of the complete SDK (comprising both the Rockchip Android 16 SSI SDK and the Android 14 SDK) is shown below:

❶ Extract Source Code

mkdir RK3676_Android16.0
tar xvf rk3576_android14_sdk-20260528.tar.gz -C RK3676_Android16.0
tar xvf Rockchip_Android16.0_SDK_RELEASE.tar.gz -C RK3676_Android16.0
cd RK3676_Android16.0/Rockchip_Android16.0_SDK_RELEASE/

❷ Configuration

source build/envsetup.sh
lunch ssi_16_arm64-bp2a-userdebug

❸ Link Android 14 SDK and configure compilation parameters
