3.7章节

参照此手册完成本章节后，编译内核之前还应再修改两处,不然不出现很多错误，在此不列出错误内容.

1.因为这个mach-mini2440.c是从mach-smdk2440.c处复制过来的，mach-smdk2440.c中未对nand作处理，但这里我们作处理啦，所以应在文件中加入相应的头文件

#include

2.不作下面的修改之前如果编译，以然会出现一个警告

warning:

"mini2440_nand_info"definedbutnotused.

解决方法:

在staticvoid__initmini2440_map_io（void）

{

}

中加入以下代码:

s3c_device_nand.dev.platform_data=&mini2440_nand_info;

3.8章节

完全按照此章节修改好程序后，编译下载到开发板，并下载自已制作适合自已开发板（64M）的文件系统，后出现下面的问题
