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 boot.tar.bz2 --system system.tar.bz2 --userdata 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 boot.tar.bz2 --system system.tar.bz2 --userdata userdata.tar.bz2

To find run linaro-android-media-create with a -h and read the help.

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

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 -h #To print the script usage

Most commonly used build options:

  $ ./linaro_android_build_cmds.sh -t #To build from the tip of the branch without overlay
  $ ./linaro_android_build_cmds.sh -t -o <overlay> #To build from the tip of the branch with provided overlay
  $ ./linaro_android_build_cmds.sh -m <pinned_manifest> -o <overlay> #To reproduce an exact build from pinned manifest
  $ ./linaro_android_build_cmds.sh -t -l <login-id> #Provide login/access ID to clone and build code from linaro-private repositories
