### Device specific configuration to build AOSP Android 13 for Raspberry Pi 4.
|
|
|
|
***
|
|
|
|
### How to build:
|
|
|
|
1. Establish [Android build environment](https://source.android.com/setup/initializing) and install [repo](https://source.android.com/docs/setup/develop#installing-repo).
|
|
|
|
2. Install additional packages (TODO: possibly non-exhaustive):
|
|
|
|
```
|
|
sudo apt-get install bc coreutils dosfstools e2fsprogs fdisk kpartx mtools ninja-build
|
|
sudo snap install meson
|
|
pip3 install ply
|
|
```
|
|
|
|
3. Initialize repo:
|
|
|
|
```
|
|
repo init -u https://android.googlesource.com/platform/manifest -b android-13.0.0_r24
|
|
curl --create-dirs -L -o .repo/local_manifests/manifest_brcm_rpi4.xml -O -L https://raw.githubusercontent.com/raspberry-vanilla/android_local_manifest/android-13.0/manifest_brcm_rpi4.xml
|
|
```
|
|
|
|
You can also reduce download size by creating a shallow clone and removing unneeded projects (optional):
|
|
|
|
```
|
|
repo init -u https://android.googlesource.com/platform/manifest -b android-13.0.0_r24 --depth=1
|
|
curl --create-dirs -L -o .repo/local_manifests/remove_projects.xml -O -L https://raw.githubusercontent.com/raspberry-vanilla/android_local_manifest/android-13.0/remove_projects.xml
|
|
```
|
|
|
|
4. Sync source code:
|
|
|
|
```
|
|
repo sync
|
|
```
|
|
|
|
5. Compile:
|
|
|
|
```
|
|
. build/envsetup.sh
|
|
lunch aosp_rpi4-userdebug
|
|
make bootimage systemimage vendorimage -j$(nproc)
|
|
```
|
|
|
|
6. Make flashable image:
|
|
|
|
```
|
|
./rpi4-mkimg.sh
|
|
```
|
|
|
|
