* | |
* | 扇区头 | 8K * 1
* | |
* -----------------
* | |
* | N*数据扇区 | 8K * 31

* -----------------
*
* 扇区头存储 31* zeeprom_sector_info_t个结构体
* 结构体:zeeprom_sector_info_t * 31
* uint8_t usage; // 0:空闲 1:已使用
* uint8_t opened; // 0:未打开 1:已打开
* uint8_t filename[8]; // 文件名
* int32_t sector_index_in_file; // 当前扇区中文件数据的起始地址
* int32_t datalen; // 当前扇区中文件数据的长度
* uint32_t checksum; // 文件数据的校验和
* int32_t fileuuid; // 递增，根据这个index判断文件创建的先后顺序，同时也相当于文件唯一标识
* uint8_t usrdata[20]; // 用户数据
*
*
* 文件的概念:
* 1.一个文件由一个或多个扇区组成，每个扇区的大小为8K,
* 2.同一个文件依靠fileuuid进行判定
* 3.如果想要读取文件大小，只需计算相同fileuuid的所有zeeprom_sector_info_t.datalen的和即可。
* 4.文件顺序依靠sector_index_in_file进行判断
* 5.文件名保存在sector_index_in_file为0的zeeprom_sector_info_t结构体中
*
* 扇区头的特殊性:
* 1. 扇区头常驻内存中
* 2. 如果期望掉电丢弃数据，扇区头不保存导flash中即可
