Tutorial #1 - Android running from SD card

This is a step by step video tutorial with all the commands to go from Ubuntu installation through Zoom2 Android boot up. The text for this installation is located at the bottom of the page.

Note: If you are planning to build new releases (L25.10 and above) please also follow the text guide as there are changes at few places. This guide is for L25.7 release.

Install Applications

# sudo apt-get install git-core flex bison gperf libesd0-dev 
# sudo apt-get install libwxgtk2.6-dev zlib1g-dev build-essential
# sudo apt-get install libstdc++5 tofrodos libsdl-dev zip curl x-dev 
# sudo apt-get install libx11-dev libncurses5-dev sun-java5-jdk libc6-dev g++ gcc

Install Compilers

$ firefox
This would also work with version 2008q3; which is a newer version.
//(Select ARM GNU/Linux and IA32 GNU/Linux options)
$ mkdir /home/user/bin
//copy download zip to /home/user/bin and unzip here
$ cp /home/user/Desktop/arm-2007q3-51-arm-none-linux-gnueabi-i686-pc-linux-gnu.tar.bz2 /home/user/bin/
$ cd /home/user/bin
$ tar -xjvf arm-2007q3-51-arm-none-linux-gnueabi-i686-pc-linux-gnu.tar.bz2
//Edit .bashrc shell setup
$ cd /home/user
$ gedit .bashrc
//add following to the end
export PATH=/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games
export PATH=$PATH:/home/user/bin/arm-2007q3/bin
//save and exit
//apply the path changes
$ source .bashrc
//verify path is ok for tools
$ which arm-none-linux-gnueabi-gcc
// should see /home/user/bin/arm-2007q3/bin/arm-none-linux-gnueabi-gcc

Configure Git Proxy (optional)

Use this only if you need to work with a proxy.

$ firefox
//download tar package to Desktop
$ cp /home/user/Desktop/corkscrew-2.0.tar.gz /home/user/bin
$ cd /home/user/bin
$ tar -zxvf corkscrew-2.0.tar.gz
$ cd corkscrew-2.0
$ ./configure
$ make
//add path to .bashrc
$ cd /home/user
$ gedit .bashrc
// add path
export PATH=$PATH:/home/user/bin/corkscrew-2.0 #for corkscrew
$ source .bashrc
$ cd /home/user/bin
$ gedit git-proxy
// add the following 3 lines
# exec <path to corkscrew>/corkscrew <proxy name> <proxy port> $*
exec /home/user/bin/corkscrew-2.0/corkscrew 80 $*
//save and exit
$ chmod a+x ~/bin/git-proxy
//now tell git you want to use a proxy.
//git config --global core.gitproxy '<path to proxy>/git-proxy'
$ git config --global core.gitproxy '/home/user/bin/git-proxy'

Getting the Source

// verify the directory /home/user/bin exist from COMPILER step above
$ curl >~/bin/repo
$ chmod a+x ~/bin/repo
//check manifest comments for latest release id
//in this case we see 25.7
$ mkdir /home/user/l25.7
$ mkdir /home/user/l25.7/mydroid
$ cd /home/user/l25.7/mydroid
//The following command is to instruct to download the manifests for
//the project. The manifests are documents used to select between different
//source versions. You can add a -b <branch name> to select specific branches.
// repo init -u git:// -b myBranch)
$ repo init -u git://

// enter name and password
// user
// now sync, this will download the source and will take a while about 1hour
// repo sync uses the manifest documents to select between the different source versions
$ repo sync


$ cd /home/user/l25.7/mydroid/bootloader/u-boot/
//make CROSS_COMPILE=/<path>/arm-none-linux-gnueabi- omap3430zoom2_config
