如题，首先在https://github.com/raspberrypi/linux/上下载最新的内核源代码，连接如下：https://github.com/raspberrypi/linux/archive/rpi-3.2.27.zip然后安装编译工具如gcc、make、patch等，可以使用apt-get install gcc make命令
然后检查系统时间，如果时间不对，可以手动设置一下时间，也可以重新启动ntp服务，自动对时
将下载的内核文件放在随便找个目录放着，并用unzip解压它，
unzip rpi-3.2.27.zip
如果命令不成功则可能是没有安装unzip，可以使用apt-get install unzip命令安装就行了
开始编译内核，首先使用以下命令对内核进行配置
make menuconfig
载图太麻烦了，所以我直接用鼠标选了图，大家将就的看看吧。
需要说明的是在System Type --->这一项里，一定要选择合适的cpu也就是armBCM2708这个型号，其它的东西大家可以自己选择，需要什么用星号表示将这一项编译进内核，M表示编译成模块。

复制代码
选择完了后可以使用左右键来进行选择<Select> < Exit > < Help >，退出时会自己保存配置
如果你的在做make menuconfig时没有看到上面的画面，而是看到一堆英文，则一般是没有安装libncurses5-dev开发库，使用apt-get install libncurses5-dev来安装就行了
当选择完成后直接make就可以了
make程序会自己编译内核以及模块。
安装模块使用make modules_install命令
在make运行完成后需要重新生成一个镜像。这需要使用其它的工具。
在https://github.com/raspberrypi/tools上面有一个目录mkimage,这个目录下存有这些工具，将这里面的文件全部下载下来，存放在一个目录中，然后执行下面的命令：
python imagetool-uncompressed.py 你的源代码目录/arch/arm/boot/Image
很快这个命令就会执行完成，你会发现在目录下有一个kernel.img的文件，这个就是你的新内核，将它覆盖boot目录下的kernel.img文件，现在你可以使用新内核来启动你的pi了。
