1. 从http://dl4.htc.com/RomCode/Source_and_Binaries/click-656120.tar.gz下载HTC官方的kernel源码，解压
2.从http://developer.android.com/sdk/ndk/index.html下载ndk并解压，主要是要用到里面的toolchains进行交叉编译
3.编辑 ～/.bashrc，在文件尾添加上export CCOMPILER=/home/ray/android-ndk-r7/toolchains/arm-linux-androideabi-4.4.3/prebuilt/linux-x86/bin/arm-linux-androideabi-
4。adb pull /proc/config.gz /home/user_name/android/kernel/cm-kernel/config.gz
cat config.gz | gunzip > .config
5.make ARCH=arm CROSS_COMPILE=$CCOMPILER menuconfig，根据需要进行选择
6. make ARCH=arm CROSS_COMPILE=$CCOMPILER -j`grep 'processor' /proc/cpuinfo | wc -l` 编译kernel，kernel生成在~/android/kernel/cm-kernel/arch/arm/boot/zImage
7. adb shell
#cat /proc/mtd dev: size erasesize name mtd0: 00040000 00020000 "misc" mtd1: 00500000 00020000 "recovery" mtd2: 00280000 00020000 "boot" mtd3: 04380000 00020000 "system" mtd4: 04380000 00020000 "cache" mtd5: 04ac0000 00020000 "userdata"
确定mtd2为boot分区
8. cat /dev/mtd/mtd2 > /sdcard/boot.img
adb pull /sdcard/boot.img .
9. ./extract-kernel.pl boot.img
./extract-ramdisk.pl boot.img
rm boot.img-kernel
cp zImage boot.img-kernel
./mkbootfs boot.img-ramdisk | gzip > ramdisk-boot
./mkbootimg --kernel boot.img-kernel --ramdisk ramdisk-boot --cmdline "no_console_suspend=1 console=null" -o myBoot.img --base 0x2E00000
10. adb push myBoot.img /sdcard
11. adb shell
flash_image boot /sdcard/myBoot.img
