Build System

This section covers the compilation and packaging of u-Boot, kernel, and AOSP.

Environment Setup

Ubuntu 20.04 or later is recommended.

Source Code Download

Ubuntu$

repo init -u https://github.com/radxa/manifests -b  Android14_RK3576_Radxa_rk6  -m rockchip-u-release.xml
repo sync
repo forall -c 'git lfs pull'

Image Compilation

Android system supports two compilation methods:

• Full Compilation: Used for the first build or when a complete rebuild is needed, takes longer
• Module Compilation: Used after modifying specific components, faster compilation, e.g., only the kernel module needs to be compiled when only the kernel is modified

Full Compilation

Suitable for the first build or when a complete rebuild is needed, takes longer.

Ubuntu$

source build/envsetup.sh
lunch rk3576_rock_4d-userdebug
./build.sh -UACKup

After compilation is complete, you can find the image files in the IMAGE directory.

Individual Component Compilation

Suitable for use after modifying specific components, with faster compilation speed.

U-Boot

Ubuntu$

source build/envsetup.sh
lunch rk3576_rock_4d-userdebug
./build.sh -AUup

Kernel

Ubuntu$

source build/envsetup.sh
lunch rk3576_rock_4d-userdebug
./build.sh -ACKup

AOSP

Ubuntu$

source build/envsetup.sh
lunch rk3576_rock_4d-userdebug
./build.sh -Aup

After compilation is complete, you can find the image files in the IMAGE directory.
