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 repo:
First: $ sudo apt-get update $ mkdir ~/bin $ PATH=~/bin:$PATH $ curl https://storage.googleapis.com/git-repo-downloads/repo > ~/bin/repo $ chmod a+x ~/bin/repo
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
Install fastboot
$ sudo add-apt-repository ppa:nilarimogard/webupd8 $ sudo apt-get update $ sudo apt-get install android-tools-fastboot $ sudo apt-get install android-tools-adb android-tools-fastboot
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
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
$ 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.
$ 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
Flashing newly built images
The build process creates an out directory and puts all images in the following directory:
/out/target/product/msm8916_64/
The following image files are created:
emmc_appsboot.mbn - little kernel (uboot)
boot.img - kernel and dtb files
system.img - system folder
The images can be flashed one by one via fastboot.
In order to enter fastboot mode cycle the power or press Reset key with Back key pressed.
To flash the whole system
$ cd /out/target/product/msm8916_64/ $ fastboot.exe flash aboot emmc_appsboot.mbn $ fastboot.exe flash persist persist.img $ fastboot.exe flash userdata userdata.img $ fastboot.exe flash system system.img $ fastboot.exe flash recovery recovery.img $ fastboot.exe flash boot boot.img
To flash kernel and dtbs
Sometimes the changes are done only to the android kernel, in this case there is no need to flash the whole system.
The kernel and dtb files are located in boot.img file.
Flashing it is enough
$ cd /out/target/product/msm8916_64/ $ fastboot.exe flash boot boot.img
To flash little kernel
Sometimes the changes are done only to the bootloader, in this case there is no need to flash the whole system.
The kernel and dtb files are located in emmc_appsboot.mbn file.
Flashing it is enough
$ cd /out/target/product/msm8916_64/ $ fastboot.exe flash aboot emmc_appsboot.mbn
