Getting Android Source Code

Related version information:

• Android 6.0.1_2.1.0
• kernel Yocto-2.0
• U-Boot Yocto-2.0

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

$ 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-Corp/android-manifest.git -b m6.0.1_2.1.0-ga -m release_version.xml
$ ../bin/repo sync

$ cd myandroid/bootable/bootloader/uboot-imx/
$ patch -p1 <../../../patches_android_6.0.1/6001-Uboot_Yocto_4.1.15_1.2.0-to-Android_M6.0.1_2.1.0.patch 
$ cd myandroid/kernel_imx/ 
$ patch -p1 <../patches_android_6.0.1/6001-Linux_Yocto_4.1.15_1.2.0-to-Android_M6.0.1_2.1.0.patch 
$ cd myandroid /

Building Android 6.0.1_2.1.0 image for SD card

If your product is ROM-3420A1, the product name is rom_3420_a1

$PRODUCT = rom_3420_a1

If your product is ROM-7421A1, the product name is rom_7421_a1

$PRODUCT = rom_7421_a1

If your product is RSB-4411A1, the product name is rsb_4411_a1

$PRODUCT = rsb_4411_a1

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.s

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 RSB4411,  you will be send command " lunch rsb_4411_a1-user

$ lunch $PRODUCT-user

To build boot loader

Perform the following command in terminal console

$ make -j4 bootloader

The two files, u-boot_crc.bin & u-boot_crc.bin.crc, will be located in directory, ./out/target/product/product_name

To build boot image

Perform the following command in terminal console

$ make -j4 bootimage

To build system image

Perform the following command in terminal console

$ make -j4 systemimage

simg2img is a tool that converts a sparse system image to a raw system image on a Linux host PC and is located in myandroid/out/host/linux-x86/bin/simg2img.

$ out/host/linux-x86/bin/simg2img out/target/product/$PRODUCT/system.img out/target/product/$PRODUCT/system_raw.img
$ mv out/target/product/$PRODUCT/system_raw.img out/target/product/$PRODUCT/system.img
