This section explains the setup requirements for booting from the S I ROM with an eMMC.
A precompiled image is provided in the “EVK” folder of the BS .
2.1.Booting from the SPI ROM ith an eMMC
The Images_autoinstall_sd
Images_autoinstall_sdImages_autoinstall_sd
Images_autoinstall_sd.zip
.zip.zip
.zip includes the Android EVK system image and the installation
scripts files.
The first step is to extract Images_autoinstall_sd.zip
Images_autoinstall_sd.zipImages_autoinstall_sd.zip
Images_autoinstall_sd.zip file to make the bootable Micro SD
card. Insert a card into your Linux host machine and make sure it is not mounted. Open the
terminal on your host machine, and run the script mk_install_sd.sh
mk_install_sd.shmk_install_sd.sh
mk_install_sd.sh as shown below,
replacing <device name> with the correct value for the card, for example “sdb”.
Important:
Important:Important:
Important: Make sure you are writing to the correct device or the host system environment
could be damaged.
$ sudo ./mk_install_sd.sh /dev/<device name>
Next, on the VAB-820, set the J11 boot select jumper to the Micro SD position
shown below.

Insert the prepared Micro SD card into the VAB-820, connect an HDMI display, and power
on the VAB-820 to initiate the boot process. When the boot process is completed, you
will see the command line of Linux environment.
To install the U-Boot and Android EVK image into S I ROM and eMMC, use the following
command:
$ ./fsl-eMMC-partition.sh –f imx6q /dev/mmcblk0

Next, power on the device to initiate the boot process. When the boot process is
completed, you will see the Android desktop.
2.2. Setting up U-Boot Parameters
The first step is to connect the host machine and the VAB-820 through the COM 2
(connector J5). Use a serial port communication program such as uTTY, GtkTerm, or
Minicom, to configure the serial port setting and connect to the debug console. There you
will be able to see the U-Boot boot log and adjust settings in the U-Boot console.

2.3. Restoring Default U-Boot Parameters
If the U-Boot parameters have been modified, the “destroyenv” command in the U-Boot
console can restore the factory default settings. To restart the device, use the “reset”
command.
=> destroyenv
=> saveenv
=> reset
2.4. Using the Android Console
The first step is to connect the host machine and the VAB-820 through the COM 2
(connector J5). Use a serial port communication program such as uTTY, GtkTerm, or
Minicom, to connect to the debug console. There you will be able to see the U-Boot boot
log and adjust settings in the U-Boot console. Next, power on the VAB-820 to initiate the
boot process. When the boot process is completed you will be prompted to login.

Build Environment Setup
This section guides you through setting up the build environment for development. All
instructions are based on using Ubuntu 14.04 LTS.
To make sure that the build process completes successfully, we recommend at least
120GB of disk space, and 15GB of combined memory and swap space on the host machine.
3.1. Configuring Ubuntu
The following packages are required for the Android development environment. The
required packages can be installed using the commands below. To get more information,
please visit Google Android website at http://source.android.com/source/initializing.html

http://source.android.com/source/initializing.html.
OpenJDK 7 is not included in the Ubuntu 14.04 default installation. The first step is to add
a new server manually by use the following command:
$ sudo add-apt-repository ppa:webupd8team/java
$ sudo apt-get update
To install the OpenJDK 7, use the following command:
$ sudo apt-get install openjdk-7-jre
$ sudo apt-get install openjdk-7-jdk
The following packages are required for the Android development environment. To install
the required packages on the Ubuntu 14.04, use the following command:

The BS supports the following Wi-Fi modules
•EMIO-1533 USB Wi-Fi module
•EMIO-1541 mini CIe Wi-Fi module
•EMIO-5531 USB Bluetooth and Wi-Fi combo module
Due to the EMIO-5531 Wi-Fi driver conflicts with the other two modules, specify the
compiling parameter in order to build the EMIO-1533 and EMIO-1541 Wi-Fi driver into the
Android system image.
$ ./build_bsp.sh --wifi-vendor=atheros
If you forgot to specify the parameter when building the Android image for the first time,
you need to append the wpa-rebuild parameter as below.
$ ./build_bsp.sh --wifi-vendor=atheros --wpa-rebuild=true
