Getting Android Source Code

Step1 : To pull down the Android source tree to your working directory from the repositories as specified in the default manifest

$ mkdir myandroid
$ mkdir bin
$ cd myandroid/
$ curl https://storage.googleapis.com/git-repo-downloads/repo > ../bin/repo
$ chmod a+x ../bin/repo
$ ../bin/repo init -u http://advgitlab.eastasia.cloudapp.azure.com/Rockchip/android-manifest.git -b android-7.1.2
$ ../bin/repo sync

Build Instructions

$ 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

Build U-boot

$ cd u-boot
$ make rk3399_box_defconfig
$ make ARCHV=aarch64 -j12

Build Kernel

• Build for DS-100 platform

$ cd kernel
$ make ARCH=arm64 rockchip_defconfig
$ make ARCH=arm64 rk3399-ds100.img -j16

• Build the rk3399_box demoboard

$ make ARCH=arm64 rockchip_defconfig
$ make ARCH=arm64 rk3399-box-rev2.img -j16

Build Android

$ source build/envsetup.sh 
$ lunch rk3399_box-userdebug 
$ make -j4 2>&1 | tee build-log.txt

Push all image to rockdev folder

$ ./mkimage.sh

All image in rockdev/Image-rk3399_box ./mkimage.sh at previous step will repack boot.img and system.img, and copy other related image files to the rockdev/Image-rk3399_box/ directory. The common image files are listed below:

# boot.img : Android's initramfs, to initialize and mount system partition. 
# kernel.img : Kernel image.
# misc.img : Misc partition image, to switch boot mode and pass parameter in recovery mode.
# recovery.img : Recovery mode image.
# resource.img : Resource image, containing boot logo and kernel's device tree info.
# system.img : System partition image with ext4 filesystem format.
# trust.img ：File about sleep
# RK3399MiniLoaderAll_V1.05.bin ：Loader
# uboot.img ：uboot
