三星的系列NandFlash有什么区别？K9F1G08/2G08/4G08/8G08.他们都是大块(2KB每页)的NAND FLASH？他们的驱动可以完全公用？ - 第3页 - 嵌入式系统 - 电子工程世界-论坛

看手册吧。。找供应商要手册。对比下他们的这几个参数
Maker ID,Device ID,tRP, tWP, tWB,tWH, tRH

不错，顶！
我们公司用K9F1208，nand flash性价比确实比较高。但经常读写的数据我们用电池+RAM的方式。

今天把代码好好看了下,算是明白了一些.那个存储NAND FLASH消息的数据结构static FlashDevSpec astNandSpec[]在 BSP/SRC/COMMON/NandFlash/FMD/cfnand.h文件里面.FMD_Init( )的时候会根据读到的Ｍake ID+Device ID去查这个数据结构表的，查到了对应的配置参数就有了，都不需要人为去控制修改什么代码，大小块的识别，读ＩＤ号就可以判断的，所以不管接什么NandFlash，程序会自动识别，自动调用对应的驱动，不要人参与的，我的6400应该是这样的！！！

//几个相关函数的调用关系为：：
EBOOT里面的OEMPlatformInit( )----调用---1.BP_Init(  )----调用-----A.FMD_Init(  )++++B.FMD_GetInfo( )
                                       2.FMD_GetInfo( )
                                       3.GetNandInfo( )

1。其中NBOOT会自己去读NAND FLASH的ID号，大块就把g_bLargeBlock标志置为TRUE，如果是真了，NAND_ReadPage(  )读扇区的操作就有附加工作要做，大块了，操作的次数就要多

2。EBOOT里面已经在OEMPlatformInit(  )函数里面用BP_Init(  )函数对所外接的NAND FLASH进行了必要的初始化，所以他可以直接调用BP_XXX(  )和FMD_XXX(  )系列函数了，并且不会出错

3。NK里面加载了NAND FLASH的驱动，所以调用FMD_XXX(  )系列函数进行文件的读/写也不会有问题了

整个工作流程应该就是这样的！！！-----我的BSP是6400的，2440就不清楚了！
