Android 4.0 on BeagleBoard and Beagleboard-xM

Sola has written the instructions (in Japanese) to build Android 4.0 (ICS) for Beagleboard and Beagleboard-xM.

Here’s the same in English:
Get the source code:

$ mkdir -p /home/sola/work/ics
$ cd /home/sola/work/ics
$ export ANDROID_ROOT=$PWD
$ repo init -u https://bitbucket.org/sola/android_manifest
$ repo sync -j8

Build Android:

$ cd $ANDROID_ROOT
$ source build/envsetup.sh
$ lunch full_beagleboard_xm-eng [for BeagleBoard-xM]
$ lunch full_beagleboard-eng [for BeagleBoard]
$ time make -j8

Generate the rootfs:

$ cd $ANDROID_ROOT/out/target/product/beagleboard_xm/ [for BeagleBoard-xM]
$ cd $ANDROID_ROOT/out/target/product/beagleboard/ [for BeagleBoard]
$ mkdir rootfs
$ sudo cp -a ./root/* ./rootfs/
$ sudo cp -a ./system/* ./rootfs/system/

Build the kernel:

$ export ARCH=arm
$ export CROSS_COMPILE=$ANDROID_ROOT/prebuilt/linux-x86/toolchain/arm-eabi-4.4.3/bin/arm-eabi-
$ cd $ANDROID_ROOT/board/beagleboard/kernel
$ make omap3_beagle_android_defconfig
$ make uImage modules -j8

Partition the SD card bootloader, media, rootfs:

$ cd $ANDROID_ROOT/board/beagleboard/sdcard
$ sudo LANG=C ./mksdcard_beagle.sh /dev/sdx

where /dev/sdx depends on your setup (e.g. /dev/sda).

Generate boot.scr:

$ cd $ANDROID_ROOT/board/beagleboard/bootscript
$ ./mkbootscr

Copy MLO/u-boot.bin/uImage/rootfs to the SD card:

$ cd $ANDROID_ROOT
$ sudo cp -a board/beagleboard/x-loader/MLO /media/boot/
$ sudo cp -a board/beagleboard/u-boot/u-boot.bin /media/boot/
$ sudo cp -a board/beagleboard/bootscript/boot.scr /media/boot/
$ sudo cp -a board/beagleboard/kernel/arch/arm/boot/uImage /media/boot/
$ cd $ANDROID_ROOT/out/target/product/beagleboard_xm/ [for BeagleBoard-xM]
$ cd $ANDROID_ROOT/out/target/product/beagleboard/ [for BeagleBoard]
$ sudo cp -a ./rootfs/* /media/rootfs/
$ sudo chmod 777 -R /media/rootfs
