Objective: Configure and Build Android on Beagle Board
Requirements:
(1) Install needed software packages At the time of this writing, note that Android requires Sun’s Java5 JDK, and doesn’t support the Java6 one.
 Install following packages as below. $ apt-get install git-core bison sun-java5-jdk flex g++ zlib1g-dev $ apt-get install libx11-dev libncurses5-dev gperf uboot-mkimage Sun JDK version 1.5 or 5 is deleted from Ubuntu 10.4 and 9.10 repositories and the version 6 has been replaced. The easiest way to install Sun JDK 5 version is add its repository from Ubuntu 9.04 to the list of repositories in 9.10 and 10.04. For this purpose, follow the steps as below.
- Open /etc/apt/sources.list with a text editor like gedit: $ sudo gedit /etc/apt/sources.list
- Add the following lines to the end of the file then save it and close: ## For sun-java5-jdk deb http://ir.archive.ubuntu.com/ubuntu jaunty-updates main multiverse
 - Update the packages lists and install sun-java5-jdk:
$ sudo aptitude update $ sudo aptitude install sun-java5-jdk (2) Android also uses its own repo script as a git front-end $ mkdir -p ~/bin $ cd ~/bin $ wget http://android.git.kernel.org/repo
 $ chmod +x repo
 (3) We are also going to need a 2007q3 Toolchain from Code Sourcerys $ cd $ wget http://www.codesourcery.com/sgpp/lite/arm/portal/package1787/public/arm-none-linux-gnueabi/arm-2007q3-51-arm-none-linux-gnueabi-i686-pc-linux-gnu.tar.bz2
 $ cd /opt $ sudo tar jxf arm-2007q3-51-arm-none-linux-gnueabi-i686-pc-linux-gnu.tar.bz2 $ cd $ wget http://free-electrons.com/pub/demos/beagleboard/android/arm-2007q3-51-arm-none-linux-gnueabi-i686-pc-linux-gnu.tar.lzma
$ cd /opt $ sudo tar --lzma -xf ~/arm-2007q3-51-arm-none-linux-gnueabi-i686-pc-linux-gnu.tar.lzma
 (4) Download resources Following instructions will create a directory in your home directory, but of course, it can be placed anywhere!$ mkdir ~/beagledroid $ cd ~/beagledroid $ repo init -u git://labs.embinux.org/repo/android/platform/beaglemanifest.git/ $ repo sync $ cd ~ $ tar --lzma -xvf beagledroid-git-20090603.tar.lzma  (5) Building Android $ make $ make -j 4 On our machine, this took about 4 hours! (6) Building the kernel $ export CC_PATH=/opt/arm-2007q3/bin/arm-none-linux-gnueabi- $ cd ~/beagledroid/kernel $ ../vendor/embinux/support-tools/beagle_build_kernel.sh
 (7) Copying the Android root file system Android’s root file system is generated in ~/beagledroid/out/target/product/generic $ cd ~/beagledroid/out/target/product/generic $ mkdir ~/beagledroid/rootfs $ cp -a root/* ~/beagledroid/rootfs/  $ cp -a system/* ~/beagledroid/rootfs/system/ $ cd ~/beagledroid/rootfs $ sudo chown -R root.root . $ sudo chmod -R a+rwX data system
 (8) Formatting an MMC/SD card First connect your card reader to your workstation, with the MMC/SD card inside. Type the dmesg command to see which device is used by your workstation. Let’s assume that this device is /dev/sdb Type the mount command to check your currently mounted partitions. If MMC/SD partitions are mounted, unmount them. In a terminal edit partitions with fdisk: $ sudo fdisk /dev/sdb Delete any existing partition with the d command. Now, create the boot partition:Command (m for help): n Command action e extended p primary partition (1-4) p Partition number (1-4): 1 First cylinder (1-239, default 1): 1 Last cylinder, +cylinders or +size{K,M,G} (1-239, default 239): +64M
Change its type to FAT32: Command (m for help): t Selected partition 1 Hex code (type L to list codes): c Changed system type of partition 1 to c (W95 FAT32 (LBA))Using the n command again, create a second partition filling up the rest of your card (just accept default values). Now, format the partitions in your card: $ sudo mkfs.vfat -n beagleboot -F 32 /dev/sdb1 $ sudo mkfs.ext3 /dev/sdb2 Remove and insert your card again. Your new partitions should be mounted automatically. Copying data to the MMC/SD card Start by copying the X-loader and U-boot on the first partition. $ cd /media/beagleboot $ wget http://free-electrons.com/pub/demos/beagleboard/android/MLO http://free-electrons.com/pub/demos/beagleboard/android/u-boot.bin $ cp ~/beagledroid/kernel/arch/arm/boot/uImage .
 $ sudo rsync -a ~/beagledroid/rootfs/ /media/disk/ Finish by unmounting your MMC/SD partitions: $ sudo umount /media/beagleboot $ sudo umount /media/disk
(9) Boot setup The last thing left to do is to specify how the board boots Linux. Plug the Beagle board on your computer, and also connect it to a DVI-D monitor. Start minicom (corresponding to Hyperterminal in Windows) on /dev/ttyS0, or on /dev/ttyUSB0 if you are using a serial to USB adapter. Power up the board.First, stop Minicom from truncating long lines by typing [Ctrl] [a] followed by z and w. In the U-boot prompt, make the board boot automatically on the MMC/SD card: # setenv bootcmd 'mmc init;fatload mmc 0 80000000 uImage;bootm 80000000' # saveenv Now set the kernel command line arguments: # setenv bootargs console=ttyS2,115200n8 noinitrd root=/dev/mmcblk0p2 video=omapfb.mode=dvi:1280x720MR-24@50 init=/init rootfstype=ext3 rw rootdelay=1 nohz=off androidboot.console=ttyS2
 Type command as below on “beagleboard prompt” as below # boot   References: [1] Build Android on Beagle Board from Free Electron website http://free-electrons.com/blog/android-beagle/[2] Solution of problem in installing sun-java5-jdk in Ubuntu 10.04 http://zebardast.ir/en/category/java/ [3] Android on BeagleBoard information page http://code.google.com/p/rowboat/wiki/BeagleBoard [4] Configure and Build http://code.google.com/p/rowboat/wiki/ConfigureAndBuild |
