Building a ROM for Android on Ubuntu in Virtualbox

Transcription

1 Building a ROM for Android on Ubuntu in Virtualbox 1. Introduction a) Read AOSP Tour from "Embedded Android" Book b) Created Ubuntu Virtual Machine with 2 CPUs, 5GB RAM and 200GB dynamic allocation virtual disk. c) Java was not installed in Ubuntu d) Followed the instructions from e) The source code was downloaded and did not use the komban's version f) The time taken to build was easily more than 7 hours ( started the build at around 10 AM and the process was still going on by 4.30 PM - did not measure after that) g) The disk usage was around 64 GB for downloading and building AOSP. 2. Setting up Environment: JAVA SETUP a) Download Oracle Java6 JDK and JRE from b) Commands to install Java # mkdir /usr/local/java # cd /usr/local/java/ # mv /home/jevitha/downloads/jre-6u45-linux-x64.bin. # chmod +x jre-6u45-linux-x64.bin # ls -l jre-6u45-linux-x64.bin #./jre-6u45-linux-x64.bin # ls -l jre1.6.0_45/ # mv /home/jevitha/downloads/jdk-6u45-linux-x64.bin. # chmod +x jdk-6u45-linux-x64.bin #./jdk-6u45-linux-x64.bin c) Setting up JAVA in the path Add these in ~/.bashrc JAVA_HOME=/usr/local/java/jdk1.6.0_45 JRE_HOME=$JAVA_HOME/jre PATH=$PATH:$JAVA_HOME/bin:$JRE_HOME/bin export JAVA_HOME export JRE_HOME export PATH d) Test whether Java is installed properly by issuing java and javac commands. jevitha@jevitha-virtualbox:~$ java -version java version "1.6.0_45" Java(TM) SE Runtime Environment (build 1.6.0_45-b06) Java HotSpot(TM) 64-Bit Server VM (build b01, mixed mode) jevitha@jevitha-virtualbox:~$ javac -version javac 1.6.0_45 jevitha@jevitha-virtualbox:~$

2 ENVIRONMENT DETAILS gcc -v Using built-in specs.... gcc version (Ubuntu ubuntu1) make -version GNU Make Setting up the required libraries Installed the libraries mentioned for ubuntu as mentioned on #sudo apt-get install bison g++-multilib git gperf libxml2-utils 4. Configuring USB Access a) As per the instructions on the Create a file /etc/udev/rules.d/51-android.rules & copied the following lines into the file after changing the OWNER filed to the username on my machine. # adb protocol on passion (Nexus One) SUBSYSTEM=="usb", ATTR{idVendor}=="18d1", ATTR{idProduct}=="4e12", MODE="0600", OWNER="jevitha" # fastboot protocol on passion (Nexus One) SUBSYSTEM=="usb", ATTR{idVendor}=="0bb4", ATTR{idProduct}=="0fff", MODE="0600", OWNER="jevitha" # adb protocol on crespo/crespo4g (Nexus S) SUBSYSTEM=="usb", ATTR{idVendor}=="18d1", ATTR{idProduct}=="4e22", MODE="0600", OWNER="jevitha" # fastboot protocol on crespo/crespo4g (Nexus S) SUBSYSTEM=="usb", ATTR{idVendor}=="18d1", ATTR{idProduct}=="4e20", MODE="0600", OWNER="jevitha" # adb protocol on stingray/wingray (Xoom) SUBSYSTEM=="usb", ATTR{idVendor}=="22b8", ATTR{idProduct}=="70a9", MODE="0600", OWNER="jevitha" # fastboot protocol on stingray/wingray (Xoom) SUBSYSTEM=="usb", ATTR{idVendor}=="18d1", ATTR{idProduct}=="708c", MODE="0600", OWNER="jevitha" # adb protocol on maguro/toro (Galaxy Nexus) SUBSYSTEM=="usb", ATTR{idVendor}=="04e8", ATTR{idProduct}=="6860", MODE="0600", OWNER="jevitha" # fastboot protocol on maguro/toro (Galaxy Nexus) SUBSYSTEM=="usb", ATTR{idVendor}=="18d1", ATTR{idProduct}=="4e30", MODE="0600", OWNER="jevitha" # adb protocol on panda (PandaBoard) SUBSYSTEM=="usb", ATTR{idVendor}=="0451", ATTR{idProduct}=="d101", MODE="0600", OWNER="jevitha" # adb protocol on panda (PandaBoard ES) SUBSYSTEM=="usb", ATTR{idVendor}=="18d1", ATTR{idProduct}=="d002", MODE="0600", OWNER="jevitha" # fastboot protocol on panda (PandaBoard)

Did not setup ccache Since was mentioned as optional setup 6. Install Repo tool Make sure you have a bin/ directory in your home directory and that it is included in your path: $ mkdir ~/bin $ PATH=~/bin:$PATH Download the Repo tool and ensure that it is executable: $ curl > ~/bin/repo $ chmod a+x ~/bin/repo sha1sum on repo matched For version 1.21, the SHA-1 checksum for repo is b8bd1804f432ecf1bab730949c82b93b0fc5fede 7. Downloading sources $mkdir android $ cd android Run repo init to bring down the latest version of Repo with all its most recent bug fixes. $ repo init -u Figured out the build number from under SOURCE CODE TAGS AND BUILDS section. To check out a branch other than "master", specify it with -b: $ repo init -u -b android-4.4.4_r1 $ repo sync 8. Initialize Build environment Initialize the environment with the envsetup.sh script $ source build/envsetup.sh or

4 build/envsetup.sh 9. Choose a Target Choose which target to build with lunch. The exact configuration can be passed as an argument, e.g. root@jevitha-virtualbox:/usr/local/java/android# lunch You're building on Linux Lunch menu... pick a combo: 1. aosp_arm-eng 2. aosp_x86-eng 3. aosp_mips-eng 4. vbox_x86-eng 5. mini_armv7a_neon-userdebug 6. mini_mips-userdebug 7. mini_x86-userdebug 8. aosp_grouper-userdebug 9. aosp_flo-userdebug 10. aosp_deb-userdebug 11. aosp_tilapia-userdebug 12. aosp_manta-userdebug 13. aosp_hammerhead-userdebug 14. aosp_mako-userdebug Which would you like?
