Introducing BSP

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

Overview

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)
processors/imx/ : HAL (Hardware Abstraction Layer)
image/ : all built images
scripts/ : simplify building process (refer to 1.4 & 1.5)

Naming Rule

It consists of model name + "AB" + version number.
Example: 4410ABV2080 → "4410" = RSB-4410, "AB" = Android BSP, "V2080" = version 2.080.

Other model names:

3420 → ROM-3420
5420 → ROM-5420
7420 → ROM-7420
DS31 → UBC-DS31
U220 → UBC-220

Conventions

${BOARD} : target board (rsb_4410 / rom_3420 / rom_5420 / rom_7420 / ubc_ds31 / ubc_200)
${BSPHOME} : BSP root directory
${SD_DEVICE} : SD card device in Ubuntu (e.g. /dev/sdf)
${MMC_DEVICE} : on-board eMMC device in Android (e.g. /dev/block/mmcblk0)

Debug console / serial console: serial terminal program (minicom, putty, teraterm) at 115200 8N1.
Terminal console: terminal program (gnome-terminal, xfce4-terminal).

Build Instructions

To build everything

Engineer version (default):

cd ${BSPHOME}/scripts
./mk_android.sh ${BOARD}

User version:

cd ${BSPHOME}/scripts
./mk_android.sh ${BOARD} user

To build boot loader

cd ${BSPHOME}/scripts
./mk_bootloader.sh ${BOARD}

To build boot image

cd ${BSPHOME}/scripts
./mk_bootimg.sh ${BOARD}

To build recovery image
