+    如果在IAR或KEIL的编辑器中阅读,请将编辑器的字体设置为新宋体(9号/五号),缩进的TAB设置为4。
+    否则,方框处出现不对齐的问题。
+
+    【待完善的地方】
+    (1)在操作NAND Flash时,如下语句是一个死循环。如果硬件出现异常,将导致软件死机
+        while( GPIO_ReadInputDataBit(GPIOG, GPIO_Pin_6) == 0 )
+
+    (2)没有增加ECC校验功能。ECC可以检查1个或2个bit错误,如果只有1个bit错误,则可以修复这个bit。如果
+        多余2个bit错误,则可能检测不到。
+
+    (3)正常写文件操作时,会导致重建LUT。目前,重建LUT的代码执行效率还不够高,有待完善。
+
+    【硬件说明】
+    安富莱STM32F103ZE-EK开发板配置的NAND Flahs为海力士的HY27UF081G2A
+    (1)NAND Flash的片选信号连接到CPU的FSMC_NCE2,这决定了NAND Flash的地址空间为 0x70000000(见CPU的数据
+        手册的FSMC章节)
+    (2)有FSMC总线上有多个总线设备(如TFT、SRAM、CH374T、NOR),因此必须确保其他总线设备的片选处于禁止
+        状态,否则将出现总线冲突问题 (参见本文件初始化FSMC GPIO的函数)
+
+
+    【NAND Flash 结构定义】
+     备用区有16x4字节,每page 1024字节,每512字节一个扇区,每个扇区对应16自己的备用区:
+
+     每个PAGE的逻辑结构,前面512Bx4是主数据区,后面16Bx4是备用区

+
+    K9F1G08U0A 和 HY27UF081G2A 是兼容的。芯片出厂时,厂商保证芯片的第1个块是好块。如果是坏块,则在该块的第1个PAGE的第1个字节
+    或者第2个PAGE(当第1个PAGE坏了无法标记为0xFF时)的第1个字节写入非0xFF值。坏块标记值是随机的,软件直接判断是否等于0xFF即可。
+
+    注意:网上有些资料说NAND Flash厂商的默认做法是将坏块标记定在第1个PAGE的第6个字节处。这个说法是错误。坏块标记在第6个字节仅针对部分小扇区(512字节)的NAND Flash
+    并不是所有的NAND Flash都是这个标准。大家在更换NAND Flash时,请仔细阅读芯片的数据手册。
+
+
+    为了便于在NAND Flash 上移植Fat文件系统,我们对16B的备用区采用以下分配方案:

+    - BI : 坏块标志(Bad Block Identifier)。每个BLOCK的第1个PAGE或者第2个PAGE的第1个字节指示该块是否坏块。0xFF表示好块,不是0xFF表示坏块。
+    - USED : 该块使用标志。0xFF表示空闲块;0xF0表示已用块。
+    - LBN0 LBN1 : 逻辑块号(Logic Block No) 。从0开始编码。只在每个BLOCK的第1个PAGE有效,其它PAGE该字段固定为0xFF FF
+    - ECC0 ~ ECC6 : 512B主数据区的ECC校验 (按照三星提供ECC算法,256字节对应3个字节的ECC)
+    - S-ECC1 S-ECC0 : LSN0和LSN2的ECC校验
+    - RSVD : 保留字节,Reserved
+
+    【坏块管理 & 磨损平衡】
+    (1) 内部全局数组s_usLUT[]按次序保存物理块号。用于物理块和逻辑块的地址映射。
+    (2) 格式化时,将98%的好块用于主数据存储。剩余的2%用于备用区(坏块替换)。
+    (3) 写扇区(512B)时,如果扇区内容为空,则直接写入,减少不必要的块擦除操作。有效提高NAND Flash的寿命和读写性能。
+    (4) 写扇区时,如果扇区内容不为空,则从末尾开始查找一个空闲块替换掉旧块,替换并改写数据完成后,将旧块擦除,并标注为空闲,之后重建LUT。
+    (5) 块复制时,充分利用NAND Flash硬件的Copy-Back功能,无需读源页到内存再写入目标页。这样可显著提高读写效率。
+    (6) 磨损平衡还存在缺陷,效果不好。ECC校验暂未实现。
