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 ...)

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 [] & [] 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

Creating boot-up on-board flash from prebuilt image

To create one boot-up SD card

Perform the following command in terminal console

$ gunzip -c ${PREBUILT_IMAGE | dd of=${SD_DEVICE} bs=1M

To transfer whole system to on-board flash

Boot up from SD card

Perform the following commands in debug console

# cd /mk_inand

# ./mksd-linux.sh /dev/mmcblk0

press y followed by Enter, if following message shows up:

While "[Done]" shows up means the transferring is finished.

Creating boot-up on-board flash from built sdcard image

To create one boot-up SD card

Perform the following commands in terminal console

$ pushd ${BSP_HOME}/${BDIR}/tmp/deploy/images/${MC}

$ dd if=${SDCARD_IMAGE} of=${SD_DEVICE} bs=1M

$ popd

To transfer whole system to on-board flash

Boot up from SD card

Insert USB stick that contains ${SDCARD_IMAGE}, USB stick will be auto mounted to /media/sda1.

Perform the following commands in debug console

# umount /media/mmcblk0p?

# cd /media/sda1

# dd if=${SDCARD_IMAGE} of=/dev/mmcblk0 bs=4M conv=fsync

# P2START=$(fdisk -lu | grep mmcblk0p2 | awk '{print $2}')

# echo -e "d\n2\nn\np\n2\n${P2START}\n\nw\n" | fdisk -u /dev/mmcblk0

# umount /media/mmcblk0p2

# e2fsck -f -y /dev/mmcblk0p2

# resize2fs /dev/mmcblk0p2

# poweroff
