void OutPutFile(void)
{ unsigned int a;
FILINFO finfo;
DIR dirs;
FATFS fs;
FIL fsrc;
char path[50]={""};

if (f_opendir(&dirs, path) == FR_OK)
{
    while (f_readdir(&dirs, &finfo) == FR_OK)
    {
      printf("read dir OK\n");
      if (finfo.fattrib & AM_ARC )
      {
        if(!finfo.fname[0])   break;      //?????????? ?????????á??
        printf("\r\n file name is:\n   %s\n",finfo.fname);
        res = f_open(&fsrc, finfo.fname, FA_OPEN_EXISTING | FA_READ);

  f_close(&fsrc);
      }
    }
}

程序运行到f_readdir(&dirs, &finfo) 就死机了求赐教
