This guide provides step-by-step instructions for setting up a build environment, downloading the source code, building, and flashing Android 14 on the Radxa O6.
Recommend Ubuntu 22.04 64-bit as the build host. For other systems, refer to the official Android docs: Establishing a Build Environment.
- Disk Space: At least 400 GB of free space for source code checkout and build.
- RAM: At least 32 GB of RAM is strongly recommended for a smooth build experience.
$ mkdir -p ~/bin
$ wget 'https://storage.googleapis.com/git-repo-downloads/repo' -P ~/bin
$ chmod +x ~/bin/repoAndroid 14 requires OpenJDK 17. Install it and other necessary packages using the commands below.

$ mkdir cix-android14
$ cd cix-android14Then run:
$ ~/bin/repo init -u https://github.com/radxa/cix-android-manifests.git -b cix_radxa_o6_rc2 -m cix_radxa_o6_release.xml
$ repo sync -j$(nproc)
$ repo forall -c 'git lfs pull'It might take quite a bit of time to fetch the entire AOSP source code!
Download Repo
$ curl https://mirrors.tuna.tsinghua.edu.cn/git/git-repo -o repo
$ export REPO_URL='https://mirrors.tuna.tsinghua.edu.cn/git/git-repo/'You can switch AOSP downloads to the Tsinghua University mirror for faster sync:
$ cd .repo/manifests
$ git diff cix_radxa_o6_release.xml
diff --git a/cix_radxa_o6_release.xml b/cix_radxa_o6_release.xml
