在飞凌提供的BSP中，Nandflash采用的是FMD+PDD的结构，PDD主要是应对上层的接口，这里我们不需要修改，直接修改FMD就好。（至于在网上看到很多人说这个结构理论上不支持MLC的Nandflash,这个暂且不说）。
FMD部分的驱动源码在 C:\WINCE600\PLATFORM\SMDK6410\src\common\nandflash\FMD\ 这个目录下边。
FMD的目录结构：
nand.s
cfnand.h
fmd_LB.h（实际并没用到）
fmd_SB.h（实际并没用到）
nand.h
fmd.cpp
sources
makefile

这个代码是飞凌提供的，且看这一句 TARGETNAME=nandflash_lib11,经查实，FMD+PDD使用的是FMD产生的nandflash_lib.lib库文件，而不是nandflash_lib11.lib文件，这也说明飞凌在这方面留了一手，并没有直接提供可用的源码，而是给了一个lib库给我们。
在这里，我们需要把 TARGETNAME=nandflash_lib11 修改为 TARGETNAME=nandflash_lib

Module Name: S3C6410.H
Abstract: FLASH Media Driver Interface Samsung S3C6410 CPU with NAND Flash
controller.
Environment: As noted, this media driver works on behalf of the FAL to directly
access the underlying FLASH hardware. Consquently, this module
needs to be linked with FLASHFAL.LIB to produce the device driver
named FLASHDRV.DLL.
