Setup Docker

Install Docker

• Before you use Docker to develop, you have to install Docker on your platform. Please refer to Docker Installation Guide. You are able to install Docker on Linux, Cloud, Windows, and OS X. In general, you may choose to install on Ubuntu.

Get base image

To get the images we provided, you can use docker pull <IMAGE REPOSITORY> to get the images in the image list.

$ docker pull advrisc/u14.04-imx6abv4
$ docker run --name rkABV2500 -it advrisc/u14.04-imx6abv4 /bin/bash

Getting Android Source Code

Related version information:

• Android 6.0.1
• kernel 3.10.0
• U-Boot 2014-10

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 https://github.com/ADVANTECH-Rockchip/android-rk-manifest.git -b android-6.0.1 -m[ release_version.xml ]
$ ../bin/repo sync

=== The release_version.xml  is an option, the default value is default.xml        please refer :  https://github.com/ADVANTECH-Rockchip/android-rk-manifest/tree/android-6.0.1 ====

Building Android 6.0.1 image

Start Docker Container

$ docker run -it --name android6.0-build -v /home/adv/myandroid:/home/adv/android6.0:rw advrisc/u14.04-imx6abv4 /bin/bash

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 userdebug type.  If you devices is RSB4680,  you will be send command " lunch rsb4680-userdebug

$ lunch $PRODUCT-userdebug

To build boot loader

Perform the following command in terminal console

$ cd u-boot/
$ make rk3288_rsb4680a3_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-a3.img

To build system image

Perform the following command in terminal console

$ make -j4
$./mkimage.sh

all android image will be generated in rockdev/Image-rsb4680/ folder.
