记录下RL-FLASHFS出现的问题，
写数据部分代码：

fsTime timedate;
sys_time_t* sys_time;
const uint8_t WriteText[] = {"序号,帧 类 型,ID,帧 数 据,时间\r\n"};
char frame_type[10]; // 帧类型:1:扩展数据帧,2:标准数据帧,3:标准远程帧,4:扩展远程帧
sys_time = get_sys_time();
/*
1. 打开文件，如果没有此文件会自动创建。
2. 第二个参数表示向此文件写数据都从尾部开始添加。
*/
/* 写数据，如果是第一次写数据 */
if ((FILE_SAVE_CLOSE == can_save_msg->file_state) || (0 == (can_save_msg->frame_idx%CAN_SAVE_PER)))
