VAR-SOM-MX6 evaluation kit.
DART-SD410 evaluation kit.


== 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 12.04 64bit LTS [http://www.ubuntu.com/download/desktop http://www.ubuntu.com/download/desktop]
= <span style="line-height: 1.5em;">Obtain Variscite's BSP</span> =


<span style="line-height: 1.5em;">Please download Android Board Support Package file from Variscite's FTP site.</span> <br/>
Contact [mailto:support@variscite.com Variscite support] for FTP credentials.


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


=== IMPORTANT ===
= <span style="line-height: 1.5em;">Download and Build Android Images</span> =
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.


Do not use other Ubuntu releases, other than recommended above.
<pre>
$ 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.
</pre>


=== For 64-bit Ubuntu 12.04 ===
= Rebuild Android Image =
To rebuild the Android run:
<pre>
$ source build/envsetup.sh
$ lunch msm8916_64-userdebug
$ make -j8 WITH_DEXPREOPT=true WITH_DEXPREOPT_PIC=true DEX_PREOPT_DEFAULT=nostripping | tee log.txt


The complete Android host requirments:&nbsp; [http://source.android.com/source/initializing.html source.android.com/source/initializing.html] Also the instruction are in Freescale "Android User's Guide" manual.
You can change the number of build threads (-j parameter) to a better number to make the build faster.
</pre>


The following command installs the required packages for setting up the android build host:
= <span style="line-height: 1.5em;">Flashing newly built images</span> =
<pre>First:
The build process creates an out directory and puts all images in the following directory:</br>
$ sudo apt-get install git gnupg flex bison gperf build-essential \
''/out/target/product/msm8916_64/</br>
  zip curl libc6-dev libncurses5-dev:i386 x11proto-core-dev \
The following image files are created:</br>
  libx11-dev:i386 libreadline6-dev:i386 libgl1-mesa-glx:i386 \
'''emmc_appsboot.mbn''' - little kernel (uboot)</br>
  libgl1-mesa-dev g++-multilib mingw32 tofrodos \
'''boot.img''' - kernel and dtb files</br>
  python-markdown libxml2-utils xsltproc zlib1g-dev:i386
'''system.img''' - system folder</br>
$ sudo ln -s /usr/lib/i386-linux-gnu/mesa/libGL.so.1 /usr/lib/i386-linux-gnu/libGL.so
The images can be flashed one by one via fastboot.</br>
'''In order to enter fastboot mode cycle the power or press Reset key with Back key pressed.</br>'''
==To flash the whole system==
<pre>
$ 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
</pre>
</pre>
In addition to the packages requested on the Android website, the following packages are also needed:


=== Installing the OpenJDK ===
==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.</br>
The kernel and dtb files are located in '''boot.img''' file.</br>
Flashing it is enough
<pre>
$ cd out/target/product/msm8916_64/
$ sudo fastboot flash boot boot.img
</pre>


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.
==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.</br>
The little kernel is located in '''emmc_appsboot.mbn''' file.</br>
Flashing it is enough
<pre>
$ cd out/target/product/msm8916_64/
$ sudo fastboot flash aboot emmc_appsboot.mbn
</pre>


Java 7: For the latest version of Android
=Adding Applications=
<pre>$ sudo apt-get update
==Adding Broswer==
$ sudo apt-get install openjdk-7-jdk
*Download Browser.zip file from Variscite's FTP site into ''~/dart-sd410/source/'' directory.<br>
*The file is located in ''dart-sd410/Software/Android/AdditionalPackages/'' FTP directory<br>
*Extract the downloaded file into your android directory
<pre>
$ cd ~/dart-sd410/source/
$ unzip Browser.zip
</pre>
</pre>
Optionally, update the default Java version by running:
*Build the Android
<pre>$ sudo update-alternatives --config java
*Flash the new Android into the board by fastboot
$ sudo update-alternatives --config javac
 
==Adding GPS Test==
*Download GPSTest.zip file from Variscite's FTP site into ''~/dart-sd410/source/'' directory.<br>
*The file is located in ''dart-sd410/Software/Android/AdditionalPackages/'' FTP directory<br>
*Extract the downloaded file into your android directory
<pre>
$ cd ~/dart-sd410/source/
$ unzip GPSTest.zip
</pre>
</pre>
=== Additional packages ===
*Add the new package into your board configuration
<pre>
$ gedit ./APQ8016_410C_LA.BR.1.2.4-01810-8x16.0_5.1.1_Lollipop_P2/device/qcom/msm8916_64/msm8916_64.mk
</pre>
locate the following lines:<br>
<br>
''PRODUCT_PACKAGES += \''<br>
''    libqcomvisualizer \''<br>
''    libqcompostprocbundle \''<br>
''    libqcomvoiceprocessing''<br><br>
Add a new package to the PRODUCT_PACKAGES<br><br>
''PRODUCT_PACKAGES += \''<br>
''    libqcomvisualizer \''<br>
''    libqcompostprocbundle \''<br>
''    libqcomvoiceprocessing \ '' <br>
''    GPSTest''<br>
<br>
Save the file and exit gedit
*Build the Android
*Flash the new Android into the board by fastboot


In addition to the packages requested on the Android website, the following packages are also needed:
==Adding Geekbench==
<pre>$ sudo apt-get install uuid uuid-dev
Follow the same procedure as for GPSTest to add Geekbench into your image file.
$ sudo apt-get install zlib1g-dev liblz-dev
==Troubleshoot==
$ sudo apt-get install liblzo2-2 liblzo2-dev
If something goes wrong check the following:
$ sudo apt-get install lzop
* The downloaded files should be extracted into ''packages/apps/'' directory verify that the new directory exists
$ sudo apt-get install git-core curl
* Verify that the build process rebuilds the system.img image
$ sudo apt-get install u-boot-tools
* Verify that the fastboot burns the system.img into system partition succsessfully
$ sudo apt-get install mtd-utils
= Customizing hardware =
The DART-SD410 hardware customization should be done by changing DTS files.<br>
This [https://www.raspberrypi.org/documentation/configuration/device-tree.md article]  is very helpful for reading about the DTS files.<br>
The VAR-SD410CustmoBoard DTS files are located in ''kernel/arch/arm/boot/dts/qcom/'' folder.
The DTS file tree is:

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:
