?平台：wince6 ?+ S3C6410?
BSP：友坚BSP2.1
?前些日子，有客户要求Nandflash作为 mass storage使用，不想使用同步工具传资料。下面是具体步骤：
1.勾选 Device Drivers->USB Function->USB FUnction Clients->Mass Storage
2.SMDK6410.bat ?中的
?set BSP_USBFNCLASS=SERIAL
@REM?set BSP_USBFNCLASS=MASS_STORAGE
修改为
@REM?set BSP_USBFNCLASS=SERIAL
? set BSP_USBFNCLASS=MASS_STORAGE
3.修改platform.reg中usb function注册表
#IF 0 ;add mao for usb Mass_Storage

重新sysgen 后，下载NK后，会在pc端 发现 ?可移动磁盘，
遇到的问题：
点击打开时，提示未格式磁盘，需要格式化，但格式化时会出错，或者导致系统重启后起不来，
原因是：我的Nandflash被分为了BINFS 和FAT32 两个分区，pc识别的是BINFS分区，现在我们需要将FAT32分区映射给pc，修改public下的usbfn—class -storage-block.cpp中的g_hStore = OpenStore(g_szDeviceName);为
g_hStore = OpenPartition(g_hStore,_T("Part01")); //add mao for mass storage
重新编译后，发现第一次打开时 还是提示要格式化磁盘，格式化后可以使用，为什么需要格式化在网上查到原因：
CE6设备如果使用exFAT文件系统，作为Mass Storage盘符连接win xp系统的PC后，访问这个盘符时XP会提示此盘符未格式化，需要格式化，这是因为WINDOWS桌面系统是从Vista sp1才开始支持exfat的，后边的win7等都没有问题，而win xp识别exFAT需求安装补丁955704，文件名：WindowsXP-KB955704-x86-CHS.exe

当然如果你未选中exfat文件系统组件，我估计是没有最后这个问题的，安装补丁后，就OK了。
