Update kernel image and modules for Cubian

You have a lot of reason to replace the kernel, if you are reading this article.

First, you should setup building environment. FYI, check this if you are going to employ cross compilation.

Compile the kernel and modules using:

make uImage
make modules
make install
make modules_install

However, the later two command won’t work well on Cubian/cubieboard. We should do something ourself. That’s not very difficult.

First, replace /boot/uImage with the new.

Then copy ‘*.ko’ files into /lib/moduels/<kernel-verion>/kernel. Make the directory just like it used to be, but with new modules. I did that this way:

cp -R <directorys' names> /lib/modules/<kernel-version>/kernel/
find not -name "*.ko" -exec rm {} \;

Reboot. That’s it!

Android真机内核实验环境搭建的一种简便方法(俗称:单刷内核)

在前面的文章中提出了如何在真机中安装自己编译内核的方法：编译内核得到zImage，再用Bootimg打包得到新的Boot.img，再zip打包成ROM最后刷机的．该方法是我和徐凌云(maxwellxxx)摸索出来的土路子，通过它我们熟悉了Android系统的结构．不过操作十分繁琐，不能满足高效实验的需要．另一方面该方法的弊端在于刷机时替换了整个系统，丢失了大量系统数据．今天发现一个新的更简便的实验方案，主要是结合fastboot工具单刷内核．（之前徐凌云就一直跟我提，我也没好好试试．所以真的需要经常接受新事物 :D）
