Compilation & Firmware Packaging

Prerequisites

• Source code acquisition and environment dependency preparation completed.
• Compile with a regular user; do not compile with the root user.

Source Code into Git

The code automatically detects whether a Git repository exists, so after extracting the code you can place it into a repository as needed. If you only need a temporary build, you can create an empty repository in the extracted code root directory first:

git init

Installing Required Environment on the Host

sudo apt install qemu-user-static qemu-user binfmt-support

Entering the Build Container

For build environment consistency, use Docker to compile.

Run the following command in the source root directory to enter the Docker environment:

docker run --privileged -it --rm --hostname $(hostname) -v $(pwd):/home/build $(whoami)/androidbuilder:u22 android

Ubuntu Version Build

build_qcs8550_lu.sh script syntax:

build_qcs8550_lu.sh user|debug version

Build the user (performance) version:

./build_qcs8550_lu.sh user 01

AidLux Version Build

Enter the ubuntu/ directory and run Aidlux_build.sh:

Aidlux_build.sh user|debug version

Build the user (performance) version:

cd ubuntu/
./Aidlux_build.sh user 01

Artifact Check

After compilation, check whether the image/firmware package has been generated in the output directory agreed upon by the project, and record the corresponding version number for later flashing.

Note

Do not compile with the root user to avoid file permission issues that may cause subsequent steps to fail.
