• 80G bytes free disk spaces for build image

Install Ubuntu

• IMPORTANT! You must be able to log in as root or use sudo to have root permissions during the installation.

Go to http://releases.ubuntu.com/14.04/ and download 64-bit PC (AMD64) desktop image: http://releases.ubuntu.com/14.04/ubuntu-14.04.3-desktop-amd64.iso for the installation.

Getting Android Source Code

Related version information:

$ mkdir bin
$ cd myandroid/
$ curl https://storage.googleapis.com/git-repo-downloads/repo > ../bin/repo
$ chmod a+x ../bin/repo
$ ../bin/repo init -u https://github.com/ADVANTECH-Rockchip/android-rk-manifest.git -b android-6.0.1 [ release_version.xml ]
$ ../bin/repo sync

Building Android 6.0.1 image

If your product is RSB-4680, the product name is rsb4680

$PRODUCT = rsb4680

Build Instructions

Set the $JAVA_HOME environment variable

$ export JAVA_HOME=/usr/lib/jvm/java-7-openjdk-amd64/

Set up the environment for building. This only configures the current terminal.

$ source build/envsetup.sh

Execute the Android lunch command. In this example, the setup is for the production image of Advantech RISC platfrom device with user type.  If you devices is RSB4680,  you will be send command " lunch rsb4680-userdebug

$ lunch $PRODUCT-user

To build boot loader

Perform the following command in terminal console

$ cd u-boot/
$ make rk3288_rsb4680a2_2G_defconfig
$ make -j4

The one file, RK3288UbootLoader_V2.30.10.bin, will be located in directory

To build kernel image

Perform the following command in terminal console

$ cd kernel/ 
$ make rk3288_adv_defconfig
$ make -j4 rk3288-rsb4680-a2.img

To build system image

Perform the following command in terminal console

$ make -j4
