Get merge-gnexus-blobs script

The script is available from:

http://android.git.linaro.org/gitweb?p=device/samsung/tuna.git;a=blob_plain;f=merge-gnexus-blobs;hb=linaro_android_4.1.1

or from git:

  $ git clone git://android.git.linaro.org/device/samsung/tuna.git
  $ cd tuna
  $ git checkout -b linaro_android_4.1.1 origin/linaro_android_4.1.1

Make sure your computer is connected to the Internet, since the script downloads non-free binaries and tools to extract images.

Run merge-gnexus-blobs script, giving the directory containing the .img files as its sole argument.

The script will do the remaining bits for you, including flashing the phone.

WARNING There is no guarantee whatsoever that the build will work. If it breaks your phone, you get to keep both pieces.

Install Google Apps

If you wish to use the phone as a real phone rather than a pure development device, chances are that you want to install the Google Apps on it:

• Install the Linaro Android build as described above
• Grab the current Google Apps zip for JellyBean from http://goo.im/gapps . At the time of the writing, the current version is: gapps-jb-20120726-signed.zip
• If you downloaded from a device other than your Galaxy Nexus, transfer the file to your Galaxy Nexus using: mtp-sendfile gapps-jb*.zip 8
• Turn your Galaxy Nexus off completely (remove the battery if in doubt)
• Hold down the Volume Up and Volume Down buttons at the same time, and turn on the phone
• Use the Volume Up button to select “Recovery mode”, then press the power button to launch it. Wait for recovery to come up.
• Select “install zip from sdcard”
• Select “choose zip from sdcard”
• Choose the gapps-jb zip file you downloaded earlier (it should be in the Download/ folder)
• Select “Yes – Install gapps-jb-*-signed.zip”
• Select “+++++Go Back+++++”
• Select “reboot system now”
• Enjoy your Google Apps enabled Linaro Android build!

Get artifacts

Scroll down to the ‘Downloads’ section

Save linaro_android_build_cmds.sh to where you’d like to make your build.

Run the build script

The linaro_android_build_cmds.sh script will download the source and create the build.

  $ chmod +x linaro_android_build_cmds.sh
  $ ./linaro_android_build_cmds.sh

Get linaro image tools

Run these commands to get all the dependencies for linaro-image-tools and the tip of linaro-image-tools

  $ sudo add-apt-repository ppa:linaro-maintainers/tools
  $ sudo apt-get update
  $ sudo apt-get install linaro-image-tools

If you’re using a released build (with a -release or from releases.linaro.org), skip this step. If you’re using a “tip” build do not skip the step and do the following: $ sudo apt-get install bzr $ bzr branch lp:linaro-image-tools

Create media (SD card)

Disable automount (instructions provided for Gnome)

  $ TMP1=$(dconf read /org/gnome/desktop/media-handling/automount)
  $ TMP2=$(dconf read /org/gnome/desktop/media-handling/automount-open)
  $ dconf write /org/gnome/desktop/media-handling/automount false
  $ dconf write /org/gnome/desktop/media-handling/automount-open false

Insert an SD card

Run ‘dmesg’

$ dmesg

Look for a line that looks like the following at the end of the log

[288582.790722]  sdc: sdc1 sdc2 sdc3 sdc4 < sdc5 sdc6 >

WARNING In the next step, make sure you use /dev/“whatever you see above”.
You can erase your hard drive with the wrong parameter.

Run linaro image tools

$ linaro-android-media-create --mmc /dev/sdc --dev <BOARD> --boot out/target/product/<BOARD>/boot.tar.bz2 --system out/target/product/<BOARD>/system.tar.bz2 --userdata out/target/product/<BOARD>/userdata.tar.bz2

If you’re using tip of linaro image tools

$ ./linaro-image-tools/linaro-android-media-create --mmc /dev/sdc --dev <BOARD> --boot out/target/product/<BOARD>/boot.tar.bz2 --system out/target/product/<BOARD>/system.tar.bz2 --userdata
out/target/product/<BOARD>/userdata.tar.bz2

Restore automount

  $ dconf write /org/gnome/desktop/media-handling/automount $TMP1
  $ dconf write /org/gnome/desktop/media-handling/automount-open $TMP2

Remove the SD card from the device writer and plug it into the board.

Check console output

Plug in an USB-to-serial converter and run minicom

$ minicom -D /dev/ttyUSB0 -w -C minicom.txt
