开发板：ok6410-A
注：1）、外网网卡用的NAT方式连接，用来在window客户端用putty连接虚拟机和更新工具连上网用；
2）、第二块儿网卡用的桥接方式，用来连接开发板；
3）、串口用来在虚拟机里使用minicom连接开发板。
交叉工具：arm-linux-4.4.1.tar.gz
Minicom连接开发板：
Putty连接好虚拟机：
结束后内核能正常启动并挂载NFS系统：
接下来开始。。哈哈 ，此过程痛并快乐着。。。准备好了么？gogogo。。。。
更新最新源代码，并创建新实验分支：

新添加一个说明文件，说明一下修改源代码遵循GPL版权

注释掉默认的并新添加：
export KBUILD_BUILDHOST := $(SUBARCH)
#ARCH = $(SUBARCH)
ARCH = arm
#CROSS_COMPILE = $(CONFIG_CROSS_COMPILE:"%"=%)
CROSS_COMPILE = arm-linux
# Architecture as present in compile.h

其中的mach-mini6410.c 板子的配置与ok6410比较相似
[root@localhost mach-s3c64xx]# cp mach-mini6410.c mach-ok6410.c
修改mach-ok6410.c
/* linux/arch/arm/mach-s3c64xx/mach-ok6410.c
将文件中所有mini6410替换为ok6410
:%s/mini6410/ok6410/g
注意需要将大写的MINI6410也要替换掉（其中大部分都是输出信息，有一处与机器码有关的要更改）
