Setup Advantech Android BSP In RISC Platform

The BSP contains cross toolchain, linux kernel source code, u-boot source code, Android root file system and some scripts. It is consist of three top folders: "android", "image", "scripts".

 prebuilt/gcc/linux-x86/host/   : cross toolchain
 bootable/bootloader/uboot-imx/ : u-boot source code
 kernel_imx/                    : linux kernel source code
 device
 fsl/ : Android device related settings
 fsl-proprietary/               : modules & firmware(e.g. WiFi, GPU)
 hardware/imx/                  : HAL (Hardware Abstraction Layer)
 image/                         : all built images located in
 scripts/                       : to simplify building process

Naming Rule

It is consist of the model name followed by "AB" plus version number, for example, 4410ABV5001 which "4410" stands for RSB-4410, "AB" is acronym of Android BSP, "V5001" stands for Version 5001; other model names list below:

 "4410" stands for RSB-4410-A2
 "5420" stands for ROM-5420_B1
 "4411" stands for RSB-4411-A1

Build Instructions

[Step1]  Set  the $JAVA_HOME environment variable 

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

[Step2]  Set up the environment for building.

$ source build/envsetup.sh

[Step3]  Execute the Android lunch command. If your product is RSB-4410, please send command. User mode

lunch rsb_4410_a2-user

Eng mode

lunch rsb_4410_a2-eng

If your product is ROM-5420 B1, please send command. User mode

$ lunch rom_5420_b1-user    

Eng mode

$ lunch rom_5420_b1-eng

[Step4]  Make command to generate the image

$ make 2>&1 | tee build-log.txt

Building U-Boot images

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

Building boot.img

Perform the following command in terminal console

to do build bootimage

$ make -j4 bootimage

Building system.img

Perform the following command in terminal console

to do build systemimage

$ make -j4 systemimage

$ 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

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.
The android-tools-fsutils package includes the simg2img command for Ubuntu Linux OS.

Building recovery image

Perform the following command in terminal console

to do build recoveryimage

$ make -j4 recoveryimage

Boot up from SD card or eMMC

To create a bootable SD card

Perform the following command in terminal console

 $ cd {BSPHOME}/scripts
 $ ./mksd-android.sh ${SD_DEVICE}</code>

To create a bootable SD card

Perform the following command in terminal console

 $ cd /data/mkimage/scripts
 $ sh ./mksd-android.sh ${MMC_DEVICE}
