== Host (PC) setup requirements ==
Please refer to [https://variwiki.com/index.php?title=DART-SD410_Android_Host_Install Host requirements installation.]
 
The host development environment for Android is based on Ubuntu, please install Ubuntu version 14.04 64bit LTS [http://www.ubuntu.com/download/desktop 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:  [http://source.android.com/source/initializing.html source.android.com/source/initializing.html] Also you can refer to [https://developer.qualcomm.com/qfile/28828/lm80-p0436-2_sw-build-and-install_gd_linux_android_rev_d.pdf Software Build and Installation Guide, Linux Android].
 
The following command installs the required packages for setting up the android build host:
<pre>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
</pre>
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
<pre>$ sudo apt-get update
$ sudo apt-get install openjdk-7-jdk
</pre>
Optionally, update the default Java version by running:
<pre>$ sudo update-alternatives --config java
$ sudo update-alternatives --config javac
</pre>
=== Additional packages ===
 
In addition to the packages requested on the Android website, the following packages are also needed:
<pre>$ 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
</pre>
{{note| NOTE:<br>The build machine should have at least 60GB of free space to complete the build process.</span><br>Please refer to the AOSP documentation for latest information and instructions for setting up other Ubuntu versions http://source.android.com/source/initializing.html|info}} 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.

Hardware Requirements

DART-SD410 evaluation kit.

Please refer to Host requirements installation.

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/

Download and 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. 

$ chmod +x SD410c_build.sh
The file SD410c_build.sh can be edited and parameter $BUILD_MACHINE changed to follow the build machine. 
The best setting is number of threads of the CPU minus 2.
$ ./SD410c_build.sh
The build system will ask for credentials for repo initialization.

Rebuild Android Image

To rebuild the Android run: 

$ source build/envsetup.sh 
$ lunch msm8916_64-userdebug 
$ make -j8 WITH_DEXPREOPT=true WITH_DEXPREOPT_PIC=true DEX_PREOPT_DEFAULT=nostripping | tee log.txt

You can change the number of build threads (-j parameter) to a better number to make the build faster.

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/
$ sudo fastboot flash aboot emmc_appsboot.mbn
$ sudo fastboot flash persist persist.img
$ sudo fastboot flash userdata userdata.img
$ sudo fastboot flash system system.img
$ sudo fastboot flash recovery recovery.img
$ sudo fastboot 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/
$ sudo fastboot 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 little kernel is located in emmc_appsboot.mbn file.
Flashing it is enough 

$ cd out/target/product/msm8916_64/
$ sudo fastboot flash aboot emmc_appsboot.mbn

Adding Applications

Adding Broswer

  • Download Browser.zip file from Variscite's FTP site into ~/dart-sd410/source/ directory.
  • The file is located in dart-sd410/Software/Android/AdditionalPackages/ FTP directory
  • Extract the downloaded file into your android directory
$ cd ~/dart-sd410/source/
$ unzip Browser.zip
  • Build the Android
  • Flash the new Android into the board by fastboot

Adding GPS Test

  • Download GPSTest.zip file from Variscite's FTP site into ~/dart-sd410/source/ directory.
  • The file is located in dart-sd410/Software/Android/AdditionalPackages/ FTP directory
  • Extract the downloaded file into your android directory
$ cd ~/dart-sd410/source/
$ unzip GPSTest.zip
  • Add the new package into your board configuration
$ gedit ./APQ8016_410C_LA.BR.1.2.4-01810-8x16.0_5.1.1_Lollipop_P2/device/qcom/msm8916_64/msm8916_64.mk

locate the following lines:

PRODUCT_PACKAGES += \
libqcomvisualizer \
libqcompostprocbundle \
libqcomvoiceprocessing

Add a new package to the PRODUCT_PACKAGES

PRODUCT_PACKAGES += \
libqcomvisualizer \
libqcompostprocbundle \
libqcomvoiceprocessing \
GPSTest

Save the file and exit gedit

  • Build the Android
  • Flash the new Android into the board by fastboot

Adding Geekbench

Follow the same procedure as for GPSTest to add Geekbench into your image file.

Troubleshoot

If something goes wrong check the following:

  • The downloaded files should be extracted into packages/apps/ directory verify that the new directory exists
  • Verify that the build process rebuilds the system.img image
  • Verify that the fastboot burns the system.img into system partition succsessfully

Customizing hardware

The DART-SD410 hardware customization should be done by changing DTS files.
This article is very helpful for reading about the DTS files.
The VAR-SD410CustmoBoard DTS files are located in kernel/arch/arm/boot/dts/qcom/ folder. The DTS file tree is:
