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

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)
processors/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 consists 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, 6410 stands for RSB-6410.

Conventions

${BOARD} : target board name (list below) — rsb_4410 / rom_3420 / rom_5420 / rom_7420 / ubc_ds31 / ubc_200 / rsb_6410
${BSPHOME} : the directory that BSP tarball extracted 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):

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

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

To build system image

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

To build OTA image

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

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

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.

Software Functionality

Serial Port Test

Serial Port Setup

Click "Serial Port"
Click "Setup"
Click "Device", and choose the used device (e.g. ttymxc1)
Click "Baud rate", and choose the used baudrate (e.g. 115200)

Console Test

Open one serial console.
Click "Console"

Typing some characters (e.g. This is a test. 123456789ABCDEF) then pressing Enter in serial console, the identical message will show up in reception block as below:

On the other hand, typing some message (ex. MESSAGE from Android) in emission block, the identical message will show up in serial console as below:

Loopback Test

Plug loopback device into COM2
Click "Loopback"
The loopback test result will show up as below

Send01010101 Test

Open one serial console.
Click Send01010101.
The character "U" (01010101) will show up continuously as below:

Display Output Option

Single HDMI Display

Perform the following commands in U-Boot:

> setenv bootargs 'console=ttymxc0,115200 androidboot.console=ttymxc0 vmalloc=400M init=/init video=mxcfb0:dev=hdmi,1920x1080M@60,bpp=32 video=mxcfb1:off video=mxcfb2:off video=mxcfb3:off fbmem=28M androidboot.processors=freescale'

> reset

Single VGA Display

> setenv bootargs 'console=ttymxc0,115200 androidboot.console=ttymxc0 vmalloc=400M init=/init video=mxcfb0:dev=lcd,1920x1080M@60,bpp=32 video=mxcfb1:off video=mxcfb2:off video=mxcfb3:off fbmem=28M androidboot.processors=freescale'
> saveenv
> reset

Single LVDS Display

> setenv bootargs 'console=ttymxc0,115200 androidboot.console=ttymxc0 vmalloc=400M init=/init video=mxcfb0:dev=ldb,1024x768M@60,bpp=24 video=mxcfb1:off video=mxcfb2:off video=mxcfb3:off fbmem=28M androidboot.processors=freescale'
> saveenv
> reset

Dual Display (HDMI + VGA)

> setenv bootargs 'console=ttymxc0,115200 androidboot.console=ttymxc0 vmalloc=400M init=/init video=mxcfb0:dev=hdmi,1920x1080M@60,bpp=32 video=mxcfb1:dev=lcd,1920x1080M@60,bpp=32 video=mxcfb2:off video=mxcfb3:off fbmem=28M,28M androidboot.processors=freescale'
> saveenv
> reset

Network Setup

Wi-Fi

Click "Settings"
Turn Wi-Fi on
Choose ESSID (e.g. ESSD Testing)
Input correct password
Wi-Fi Authenticating / Connecting / Obtaining IP address
Wi-Fi connected

Ethernet

Click Settings → Ethernet configuration, then turn on Ethernet
Click Ethernet configuration
Choose Connection Type (DHCP or Static IP)

To update system

Refer to 1.4.6 to build OTA package.
Plug SD card that contains OTA package (update.zip) into SD slot.
Click Settings → About tablet → Addition system updates:
Wait for one moment, system will reboot for updating
It will take some time to update.

System Recovery

Please refer to 1.5.1 & 1.5.2 to create a bootable SD card and transfer whole system to on-board eMMC.
