注：主要参考网上的移植，结合自己的操作，再次对参考的作者的博文表示感谢！
1、下载linux-2.6.32.2.tar.gz将其拷贝到
clx@think:/work/armlinux$ ls
linux-2.6.32.2.tar.gz
将其解压到此目录下
clx@think:/work/armlinux$ tar -zxvf linux-2.6.32.2.tar.gz
clx@think:/work/armlinux$ ls
linux-2.6.32.2 linux-2.6.32.2.tar.gz
2、指定交叉编译变量
我们移植目的是让Linux-2.6.32.2 可以在mini2440上运行。首先，我们要使得Linux-2.6.32.2 的缺省目标平台成为ARM 的平台，修改总目录下的Makefile。
用gedit打开/Makefile，定位到183行，修改如下：
#Alternatively CROSS_COMPILE can be set in the environment.
# Default value for CROSS_COMPILE is not to prefix executables
# Note: Some architectures assign CROSS_COMPILE in their arch/*/Makefile
export KBUILD_BUILDHOST := $(SUBARCH)
ARCH ?= arm
CROSS_COMPILE ?= arm-linux-
#Architecture as present in compile.h
其中，ARCH 是指定目标平台为arm，CROSS_COMPILE 是指定交叉编译器，这里指定的是系统默认的交叉编译器，如要使用其它的，则要把编译器的全路径在这里写出。注意，在arm和arm-linux-后不要留空格，否则在编译时会出现错误。
3、建立自己的目标平台
(1)、关于机器码
内核在启动时，是通过bootloader传入的机器码(MACH_TYPE)确定应启动哪种目标平台的，友善之臂已经为mini2440 申请了自己的机器码为1999，它位于linux-2.6.32.2/arch/arm/tools/mach_types文件中。如果内核的机器码和bootloader传入的不匹配，就不能正确引导内核。
linux-2.6.32.2/arch/arm/mach-s3c2440 目录下有个mach-mini2440.c 文件，它其实就是国外爱好者为mini2440 移植添加的主要内容了，但我们不用它，把它直接删除。将linux-2.6.32.2/arch/arm/mach-s3c2440/目录下的mach-smdk2440.c 复制一份。命名为mach-mini2440.c
clx@think:/work/armlinux/linux-2.6.32.2/arch/arm/mach-s3c2440$ cp -p mach-smdk2440.c mach-mini2440.c
并打开文件定位到末尾处，找到
MACHINE_START(S3C2440, "SMDK2440") ， 将其修改为
MACHINE_START(MINI2440,"Mini2440 development board")
提示：开发板运行后，在命令行终端输入：cat /proc/cpuinfo 可以看到我们添加的开发板信息，当然这个信息可以定制成我们需要的信息。
(2)、修改时钟源频率
在上面我们刚刚复制并修改过的mach-mini2440.c文件中，定位到163行附近，把其中的16934400(代表原SMDK2440 目标板的晶振是16.9344MHz)改为mini2440 开发板上实际使用的12000000(代表mini2440 开发板上的晶振12MHz，元器件标号为X2)，如下所示：
static void__init smdk2440_map_io(void)
{
s3c24xx_init_io(smdk2440_iodesc,ARRAY_SIZE(smdk2440_iodesc));
s3c24xx_init_clocks(12000000);
s3c24xx_init_uarts(smdk2440_uartcfgs,ARRAY_SIZE(smdk2440_uartcfgs));
}
(3)、从SMDK2440 到MINI2440
因为我们要制作自己的mini2440平台体系，因此把mach-mini2440.c 中所有的smdk2440字样改为mini2440，在gedit里用查找替换，比较方便，操作如下：
gedit->搜索->替换，在打开的对话框中，在搜索一栏输入“smdk2440”，在替换为一栏输入“mini2440”然后点击全部替换按钮，即可完成。
除此之外，还有一个地方需要改动，在mini2440_machine_init(void)函数中，把smdk_machine_init()函数调用注释掉，因为我们后面会编写自己的初始化函数，不需要调用smdk2440 原来的，定位到173行，修改如下：
static void__init mini2440_machine_init(void)
{
s3c24xx_fb_set_platdata(&mini2440_fb_info);
s3c_i2c0_set_platdata(NULL);
platform_add_devices(mini2440_devices,ARRAY_SIZE(mini2440_devices));
//smdk_machine_init();
}
(4)、编译测试
在 Linux 源代码根目录下执行
clx@think:/work/armlinux/linux-2.6.32.2$ make mini2440_defconfig
使用Linux 官方自带的mini2440 配置
clx@think:/work/armlinux/linux-2.6.32.2$ make zImage
编译了20多分钟
clx@think:/work/armlinux/linux-2.6.32.2/arch/arm/boot$ ls
bootp compressed Image install.sh Makefile zImage
把生成的内核文件zImage下载到板子的内存中运行。

可以看到内核已经可以正常启动了，但此时大部分硬件驱动还没加，并且也没有文件系统，因此还无法登陆。
