wince nand分区的问题
nand升级之后，对nand进行读写和擦出操作都没有问题，分区也能看到分区成功了，MBR信息读取出来也是对的，进入大容量模式之后，在PC机上会显示到两个盘符和盘符大小，但是打不开，总是弹出IO错误，MBR信息如下：

大家有没有遇到过类似问题，帮忙分析下，不胜感激。
------解决思路----------------------
应该是UOE的NOP为1导致wince无法满足的原因。
之前论坛里很多人遇到过了。都不行，换别的了。

你可以去看看他的blog。
后来还有几个人也遇到同样的问题，论坛里找找。
------解决思路----------------------
nand的主要功能无非读、写和擦出，如果读写擦出都没问题证明时序是对的，然后就是block page sector等这些参数，NOP值是决定每一页的循环读写次数的，这个同时也关系到nand分区和文件系统
------解决思路----------------------
针对U0E这一问题三星官方好像也做了声明，主要对比了U0E和U0D的区别，然后论坛上也有好多人遇到过这个问题，但是貌似都没有找到解决方法，替代的话能够兼容的片子挺多的
