注意到了麽？这个跟文档中的寄存器少了8bit ECC寄存器部分。
晕菜了吧，飞凌的这个2G 256M的BSP的Nandflash源码既然是这个样子，为什么还在那里号称8bit的ECC，还说开放源码。
靠别人都行的话，母猪都会上树啦！咱还是自己搞吧！
在上面UINT32 NFMLCBITPT; //0x40 的后面添加以下代码：
[cpp] //0x44-- 8位ECC错误状态0寄存器
UINT32 NF8ECCERR1; //0x48-- 8位ECC错误状态1寄存器
UINT32 NF8ECCERR2; //0x4c-- 8位ECC错误状态2寄存器
UINT32 NFM8ECC0; //0x50-- 生成8位ECC状态0寄存器
UINT32 NFM8ECC1; //0x54-- 生成8位ECC状态1寄存器
UINT32 NFM8ECC2; //0x58-- 生成8位ECC状态2寄存器
UINT32 NFM8ECC3; //0x5c-- 生成8位ECC状态3寄存器
UINT32 NFMLC8BITPT0; //0x60-- 8位ECC错误位模式寄存器0
UINT32 NFMLC8BITPT1; //0x64-- 8位ECC错误位模式寄存器1
