Prepare Root file system

     $ cd out/target/product/beagleboard     $ mkdir android_rfs     $ cp -r root/* android_rfs     $ cp -r system android_rfs     $ cd android_rfs     $ chmod -R 777 *     $ chown root.root *

prepare tar file for android_rfs directory

Prepare uImage

     $ cd <android_root_dir>/kernel     $ make ARCH=arm omap3_beagle_android_defconfig     $ export toolchain path     $ make ARCH=arm CROSS_COMPILE=arm-eabi- uImage

For enabling USB EHCI port

1. Follow the steps in the following link to compile u-boot – http://elinux.org/BeagleBoard#U-Boot
2. copy u-boot.bin in FAT partition of SD card
