《Mini2440\_Linux移植开发实战指南》目录结构如下：

根据《Mini2440\_Linux移植开发实战指南》一文进行nandflash驱动  
的移植出现了不少问题。

首先按照步骤修改相关信息之后执行make zImage出现了不少错误：  
其中有代表性的错误如下：  
arch/arm/mach-s3c2440/mach-mini2440.c:189: error: array type has incomplete element type

arch/arm/mach-s3c2440/mach-mini2440.c:198: warning: excess elements in struct initializer

上面错误需要在mach－mini2440.c中加入下面头文件 (在mini2440linux移植开发实战指南.pdf》中没有提及)  
  
\#include <linux/mtd/mtd.h>  
\#include <linux/mtd/nand.h>  
\#include <linux/mtd/nand\_ecc.h>  
\#include <linux/mtd/partitions.h>  
\#include <plat/nand.h>

关于make警告：warning: ‘mini2440\_nand\_info’ defined but not used

这是也因为Linux移植开发实战指南对nandflash的移植漏了一个步骤：  
在static void \_\_init mini2440\_map\_io(void) 函数中添加以下代码：  
s3c\_device\_nand.dev.platform\_data = &mini2440\_nand\_info;  
然后再make zImage，下载到开发板即可。

结果如下：
