Build environment setup

Recommend build host is Ubuntu 16.04 64bit, for other hosts, refer official Android documents [Establishing a Build Environment](https://source.android.com/setup/build/initializing).

   $ mkdir -p ~/bin
   $ wget 'https://storage.googleapis.com/git-repo-downloads/repo' -P ~/bin
   $ chmod +x ~/bin/repo

In China 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/'

Android's source code primarily consists of Java, C++, and XML files. To compile the source code, you'll need to install OpenJDK 8, GNU C and C++ compilers, XML parsing libraries, ImageMagick, and several other related packages.

   $ sudo apt-get update
   $ sudo apt-get install openjdk-8-jdk python git-core gnupg flex bison gperf build-essential \
                          zip curl liblz4-tool zlib1g-dev gcc-multilib g++-multilib libc6-dev-i386 \
                          lib32ncurses5-dev x11proto-core-dev libx11-dev lib32z-dev ccache \
                          libgl1-mesa-dev libxml2-utils xsltproc unzip mtools u-boot-tools \
                          htop iotop sysstat iftop pigz bc device-tree-compiler lunzip \
                          dosfstools vim-common parted udev lzop

Configure the JAVA environment

   $ 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

Download source code

   $ mkdir rockpi4-android9
   $ cd rockpi4-android9

Then run:

   $ ~/bin/repo init -u https://github.com/radxa/manifests.git -b rockpi-box-9.0 -m rockpi-release.xml
   $ repo sync -j$(nproc) -c

It might take quite a bit of time to fetch the entire AOSP source code(around 86G)!

Build u-boot

   $ cd u-boot
   $ ./make.sh rk3399
   $ cd ..

The generated images are **rk3399_loader_v_xxx.bin** , **idbloader.img** and **uboot.img**

Building kernel

   $ cd kernel
   $ make rockchip_defconfig
   $ make rk3399-rockpi-4b.img -j$(nproc)
   $ cd ..

Building AOSP

Android TV:

   $ source build/envsetup.sh
   $ lunch rk3399_box-userdebug
   $ make -j$(nproc)

Android Tablet:

   $ source build/envsetup.sh
   $ lunch rk3399-userdebug
   $ make -j$(nproc)

It takes a long time, take a break and wait...

Generate images

   $ ln -s RKTools/linux/Linux_Pack_Firmware/rockdev/ rockdev
   $ ./mkimage.sh

The generated images under rockdev/Image are

   ├── boot.img
   ├── dtbo.img
   ├── idbloader.img
   ├── kernel.img
   ├── misc.img
   ├── oem.img
   ├── parameter.txt

   ├── pcba_whole_misc.img
   ├── recovery.img
   ├── resource.img
   ├── system.img
   ├── trust.img
   ├── uboot.img
   ├── vbmeta.img
   └── vendor.img

   $ cd rockdev
   $ ln -s Image-rk3399 Image #### Android TV (ln -s Image-rk3399_box Image)
   $ ./android-gpt.sh

The images under rockdev/Image are `gpt.img`

   ├── boot.img
   ├── gpt.img
   ├── idbloader.img
   ├── kernel.img
   ├── ......
   └── uboot.img

Installation you can use `tf card` or `emmc module`

[MicroSD Install Wiki.](https://wiki.radxa.com/Rockpi4/install/microSD) or

   $ sudo umount /dev/<Your device>*
   # mac os maybe not supprot progress
   $ sudo dd if=Image/gpt.img of=/dev/<Your device> bs=4M status=progress
   $ sync

through rockusb

  # on device u-boot
  # mmc 0 is your emmc module
  # mmc 1 is your tf card
  $ rockusb 0 mmc 1
  # on pc
  $ rkdeveloptool wl 0 Image/gpt.img

There may be some performance loss when using tf card
