New page

== 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).
<code bash>
$ mkdir -p ~/bin
$ wget 'https://storage.googleapis.com/git-repo-downloads/repo' -P ~/bin
$ chmod +x ~/bin/repo
</code>
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.
<code bash>
$ sudo apt-get update
$ sudo apt-get install openjdk-8-jdk android-tools-adb bc bison build-essential curl flex g++-multilib gcc-multilib gnupg gperf imagemagick lib32ncurses5-dev lib32readline-dev lib32z1-dev libesd0-dev liblz4-tool libncurses5-dev libsdl1.2-dev libssl-dev libwxgtk3.0-dev libxml2 libxml2-utils lzop pngcrush rsync schedtool squashfs-tools xsltproc yasm zip zlib1g-dev
</code>
Configure the JAVA environment
<code bash>
$ 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
</code>
== Download source code ==
<code bash>
$ mkdir rockpi4-android
$ cd rockpi4-android
</code>
Then run:
<code bash>
$ ~/bin/repo init -u https://github.com/radxa/rockpi4-android-tv-7.1.git -m rockchip_tv_nougat_release.xml
$ repo sync -j$(nproc) -c
</code>
It might take quite a bit of time to fetch the entire AOSP source code(around 86G)!

In China:
Download Repo
<code bash>
$ curl https://mirrors.tuna.tsinghua.edu.cn/git/git-repo -o repo
$ export REPO_URL='https://mirrors.tuna.tsinghua.edu.cn/git/git-repo/'
</code>
== Build u-boot ==
<code bash>
$ cd u-boot
$ make rock-pi-4b-rk3399_defconfig
$ ./mk-uboot.sh
$ cd ..
</code>
The generated images are **rk3399_loader_v_xxx.bin** , **idbloader.img** and **uboot.img**

== Building kernel ==
<code bash>
$ cd kernel
$ make rockchip_defconfig
$ make rk3399-rockpi-4b.img -j$(nproc)
$ cd ..
</code>
The generated images are **kernel.img** and **resource.img**:

# kernel.img, kernel with rkcrc checksum
# resource.img, contains dtb and boot logo, Rockchip format resource package

== Building AOSP ==
<code bash>
$ source build/envsetup.sh
$ lunch rk3399_box-userdebug
$ make -j$(nproc)
</code>
It takes a long time, take a break and wait...

== Generate images ==
<code bash>
$ ln -s RKTools/linux/Linux_Pack_Firmware/rockdev/ rockdev
$ ./mkimage.sh
</code>

The generated images under rockdev/Image are
<code bash>
├── boot.img

The images under rockdev/Image are `gpt.img`
<code bash>
├── boot.img
├── gpt.img
├── idbloader.img
├── kernel.img
├── ......
└── uboot.img
</code>
Installation
you can use `tf card` or `emmc module`
<code bash>
$ 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
</code>
through rockusb
<code bash>
# 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
</code>

There may be some performance loss when using tf card
