Hardware Requirements

DART-SD410 evaluation kit.

Host (PC) setup requirements

The host development environment for Android is based on Ubuntu, please install Ubuntu version 14.04 64bit LTS http://www.ubuntu.com/download/desktop At least 60GByte free space.

IMPORTANT

Do not use other Ubuntu releases, other than recommended above.

For 64-bit Ubuntu 14.04

The complete Android host requirments:  source.android.com/source/initializing.html Also you can refer to Software Build and Installation Guide, Linux Android.

The following command installs the required packages for setting up the android build host:

First:
$ sudo apt-get install git gnupg flex bison gperf build-essential \
  zip curl libc6-dev libncurses5-dev:i386 x11proto-core-dev \
  libx11-dev:i386 libreadline6-dev:i386 libgl1-mesa-glx:i386 \
  libgl1-mesa-dev g++-multilib mingw32 tofrodos \
  python-markdown libxml2-utils xsltproc zlib1g-dev:i386
$ sudo ln -s /usr/lib/i386-linux-gnu/mesa/libGL.so.1 /usr/lib/i386-linux-gnu/libGL.so

In addition to the packages requested on the Android website, the following packages are also needed:

Installing the OpenJDK

The master branch of Android in the Android Open Source Project (AOSP) requires Java 7. On Ubuntu, use OpenJDK. Be aware that you must use OpenJDK opposed to previous versions that used SUN Java.

Java 7: For the latest version of Android

$ sudo apt-get update
$ sudo apt-get install openjdk-7-jdk

Optionally, update the default Java version by running:

$ sudo update-alternatives --config java
$ sudo update-alternatives --config javac

Additional packages

In addition to the packages requested on the Android website, the following packages are also needed:

$ sudo apt-get install uuid uuid-dev
$ sudo apt-get install zlib1g-dev liblz-dev
$ sudo apt-get install liblzo2-2 liblzo2-dev
$ sudo apt-get install lzop
$ sudo apt-get install git-core curl
$ sudo apt-get install u-boot-tools
$ sudo apt-get install mtd-utils

NOTE:
The build machine should have at least 60GB of free space to complete the build process.
Please refer to the AOSP documentation for latest information and instructions for setting up other Ubuntu versions http://source.android.com/source/initializing.html

Comment for build error: If this is the first time you build on a 64bit machine you may encounter some error releated to lzo library and other. https://community.freescale.com/thread/303536 has detail information how to fix this.

Obtain Variscite's BSP

Please download Android Board Support Package file from Variscite's FTP site.
Contact Variscite support for FTP credentials.

Unpack Variscite's Android Release Package

<span style="line-height: 1.5em;">
$ mkdir ~/dart-sd410
$ cd ~/dart-sd410
$ unzip ~/Downloads/variscite_bsp_vla.br_.1.2.4-01810-8x16.0-3.zip
$ cd source/

Build Android Images

The following commands will download the full Android release from different Git repositories and build the Android images. It may take a very long time depending on Internel connection, Build machine, and remote servers. The process may fail fetching the repositories, in this case it can be started again.

Change to Android top level directory.

$ cd ~/var_ll_500_100/ll_500_100_build
$ chmod +x DB410c_build.sh
The file DB410c_build.sh can be adited and parameter $BUILD_MACHINE changed to follow the build machine. 
The best setting is number of threads of the CPU minus 2.
$ ./DB410c_build.sh
