Android ========== Android (www.android.com) is an open source operating system for mobile devices. This document describes configurations needed to run the Android framework on top of the Linux kernel. To see a working defconfig look at msm_defconfig or goldfish_defconfig which can be found at http://android.git.kernel.org in kernel/common.git and kernel/msm.git msm_defconfig should work on qualcomm reference design, HTC Magic and G1/ADP1. 1.1 Required enabled config options ----------------------------------- After building a standard defconfig, ensure that these options are enabled in your .config or defconfig if they are not already. Based off the msm_defconfig. You should keep the rest of the default options enabled in the defconfig unless you know what you are doing.

Then ./fastboot boot linux-msm/arch/arm/boot/zImage ramdisk.img Machine will freeze at rainbow screen for a while, be patient. ramdisk.img is required. 2.
