To install JDK

Please download "jdk-6u45-linux-x64.bin" manually, put it to directory ~/FILES/ and perform the following commands:

$ cd /usr/lib
$ sudo ~/FILES/jdk-6u45-linux-x64.bin
$ sudo mkdir jvm
$ cd jvm
$ sudo mv ../jdk1.6.0_45 .
$ cd jdk1.6.0_45/

$ sudo update-alternatives --config javac
$ sudo update-alternatives --config jar
$ cd ~/
$ sudo sh -c "echo "JAVA_HOME=/usr/lib/jvm/jdk1.6.0_45" >> /etc/environment"

Introducing BSP

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".

Overview

The description of some important folders as below:

android/

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 (Please refer to 1.4 & 1.5 for details)

Naming Rule

It is consist of the model name followed by "AB" plus version number, for example, 4410ABV2080 which "4410" stands for RSB-4410, "AB" is acronym of Android BSP, "V2080" stands for Version 2.080; other model names list below:

"3420" stands for ROM-3420

"5420" stands for ROM-5420

"7420" stands for ROM-7420

"DS31" stands for UBC-DS31

"U220" stands for UBC-220

Conventions

${BOARD} : target board name (list below)

rsb_4410 / rom_3420 / rom_5420 / rom_7420 / ubc_ds31 / ubc_200

${BSPHOME} : the directory that BSP tarball extacted to

${SD_DEVICE} : device name of SD card in Ubuntu (e.g. /dev/sdf)

${MMC_DEVICE} : device name of on-board eMMC in Android (e.g. /dev/block/mmcblk0)

debug console / serial console

serial terminal program (e.g. minicom, putty, teraterm ...) that serial port is configured to 115200 8N1

terminal console

terminal program (e.g. gnome-terminal, xfce4-terminal ...)

Build Instructions

To build everything

Perform one of the following commands in terminal console

engineer version (default option)

$ cd ${BSPHOME}/scripts

$ ./mk_android.sh ${BOARD}

user version

$ cd ${BSPHOME}/scripts

$ ./mk_android.sh ${BOARD} user

To build boot loader

Perform the following command in terminal console

$ cd ${BSPHOME}/scripts

$ ./mk_bootloader.sh ${BOARD}

To build boot image

Perform the following command in terminal console

$ cd ${BSPHOME}/scripts

$ ./mk_bootimg.sh ${BOARD}

To build recovery image

Perform the following command in terminal console

$ cd ${BSPHOME}/scripts

$ ./mk_recoveryimg.sh ${BOARD}

To build system image

Perform the following command in terminal console

$ cd ${BSPHOME}/scripts

$ ./mk_systemimg.sh ${BOARD}

To build OTA image

Perform the following command in terminal console

$ cd ${BSPHOME}/scripts

$ ./mk_otapackage.sh ${BOARD}

and the OTA package, update.zip, is located in the following directory

../android/out/target/product/${BOARD}.

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}

To transfer whole system to onboard eMMC

Boot up from SD card

Perform the following commands in debug console

# cd /data/mkimage/scripts

# sh ./mksd-android.sh ${MMC_DEVICE}

Remove SD card, then target board can boot up from onboard eMMC.
