3. Compile Android9.0

3.1. Download Android SDK

Since the Android SDK source code package is relatively large, you can obtain the Android 9.0 source code package in the following ways: Download link

After the download is complete, verify the MD5 code before decompression:

$ md5sum /path/to/rk3399pro_firefly_android9.0_20191126.7z.001
$ md5sum /path/to/rk3399pro_firefly_android9.0_20191126.7z.002

6e1d3969c8a0f643522727ff07800bb5  rk3399pro_firefly_android9.0_20191126.7z.001
a6b8d6a775c3d5ed28f4d41cb210a84d  rk3399pro_firefly_android9.0_20191126.7z.002

Then unzip:

cd ~/proj/
7z x ./rk3399pro_firefly_android9.0_20191126.7z.001 -oAIO-3399Pro
cd ./AIO-3399Pro
git reset --hard

The following is how to update from gitlab:

#1. Enter the SDK root directory
cd ~/proj/AIO-3399Pro

#2. Download the remote bundle warehouse
git clone https://gitlab.com/TeeFirefly/rk3399pro-pie-bundle.git .bundle

#3. If downloading the warehouse fails, the current bundle warehouse occupies a large space, so there may be stuck or failed during synchronization.
# You can download it from the Baidu Cloud link below and unzip it to the SDK root directory. The unzip command is as follows:

7z x rk3399pro-pie-bundle.7z  -r -o. && mv rk3399pro-pie-bundle/ .bundle/

#4. Update the SDK, and subsequent updates do not need to pull the remote warehouse again, just execute the following command
.bundle/update

#5. Follow the prompts to update the content to FETCH_HEAD, synchronize FETCH_HEAD to the firefly branch
git rebase FETCH_HEAD

3.2.2. Manually compile AIO-3399ProC Android 9.0

Before compiling, execute the following command to configure environment variables:

export JAVA_HOME=/usr/lib/jvm/java-8-openjdk-amd64
export PATH=$JAVA_HOME/bin:$PATH
export CLASSPATH=.:$JAVA_HOME/lib:$JAVA_HOME/lib/tools.jar
  • Compile the kernel:

cd ~/proj/AIO-3399ProC/kernel/
make ARCH=arm64 firefly_defconfig
make -j8 ARCH=arm64 BOOT_IMG=../rockdev/Image-rk3399pro_firefly_aioc/boot.img rk3399pro-firefly-aioc.img
  • Note: If you are performing kernel debugging, you need to package resource.img and kernel.img into boot.img and then burn the boot partition to take effect. Note: If you are performing kernel debugging, you need to package resource.img and kernel.img into boot.img and then burn the boot partition to take effect.

  • Compile uboot:

cd ~/proj/AIO-3399ProC/u-boot/
./make.sh rk3399pro
  • 编译 Android:

cd ~/proj/AIO-3399ProC/
source build/envsetup.sh
lunch rk3399pro_firefly_aioc-userdebug
make -j8
./mkimage.sh

3.3. Partition mirroring

  • boot.img: Android initramfs image, including the basic file system of the Android root directory, which is responsible for initializing and loading the system partition.

  • system.img: Android file system partition image in ext4 file system format.

  • kernel.img: Kernel image.

  • resource.img: Resource image, including boot image and kernel device tree.

  • misc.img: misc partition image, responsible for the switch of boot mode and the transfer of parameters in emergency mode.

  • recovery.img: Recovery mode image.

  • rk3399_loader_v1.12.112.bin: Loader file.

  • uboot.img: U-Boot image file.

  • trust.img: Arm trusted file (ATF) image file.

  • parameter.txt: partition layout and kernel command line.

  • vendor.img: TODO
