sd卡连续存储文件30多个小时后死机了，

张衍波 · 发表于 2015-10-7 13:14:10

我使用的是STM32F407，通过485接收数据，将数据以txt文件的形式存储到SD卡里，每个文件是625k，可是程序在运行到存储了300多个文件的时候死机了。

下面是程序

经过设置标志位，发现程序是在建立新文件的时候死掉的
FIL File;
FIL* CreateNewFile(void)
{
__align(8) RTC_TimeTypeDef RTC_TimeStruct; //__align(8) 8字节对其
      __align(8) RTC_DateTypeDef RTC_DateStruct;

      RTC_GetTime(RTC_Format_BIN, &RTC_TimeStruct);
      RTC_GetDate(RTC_Format_BIN, &RTC_DateStruct);

      LCD_ShowNum(200, 320, ++m, 8, 16);

      sprintf(FileName, "%02d%02d%02d%02d.txt",
            RTC_DateStruct.RTC_Date,
            RTC_TimeStruct.RTC_Hours,
            RTC_TimeStruct.RTC_Minutes,
            RTC_TimeStruct.RTC_Seconds);

      LCD_ShowNum(200, 350, ++n, 8, 16);

      while(res_open!=0)
      {
            res_open = f_open(&File, FileName, FA_OPEN_ALWAYS | FA_WRITE);
            if(++open > 2)
            {
                     sprintf(CntBuf, "f_open = %d", res_open);
         LCD_ShowString(60, 80, 210, 16, 16, CntBuf);
            }
      }
      res_open = 1; open = 0;

      while(res_lseek!=0)
      {
            res_lseek = f_lseek(&File, 0);
            if(++lseek > 2)
            {
                     sprintf(CntBuf, "f_lseek = %d", res_lseek);
         LCD_ShowString(60, 110, 210, 16, 16, CntBuf);
            }
      }
res_lseek = 1; lseek = 0;

      #ifdef __SHOW_SD_PROCEDURE__
      LCD_ShowString(60, 140, 210, 16, 16, FileName);
      #endif

      LCD_ShowString(60, 170, 210, 16, 16, " CreateNewFile = ");
      LCD_ShowNum(200, 170, ++i, 8, 16);

      return &File;
}

两个标志位都进行了更新，就是说标志位前的语句没有问题，是在f_open这出问题的，可是我在程序里面写的如果打开文件多于两次就输出"f_open = %d"，可是在测试的时候没有输出，请问是哪里出问题了？
