     SPI1_Init();
     SPI1_Init_Advanced(_SPI_MASTER_OSC_DIV64, _SPI_DATA_SAMPLE_MIDDLE, _SPI_CLK_IDLE_LOW, _SPI_LOW_2_HIGH);
     Delay_us(10);
     
     error = MMC_Init();
     while(error == 1)
     {
      Lcd_Cmd(_LCD_CLEAR);
      Lcd_Out(1,1," CARD NOT FOUND");
      error = MMC_Init();
     }
     
     Lcd_Cmd(_LCD_CLEAR);
     Lcd_Out(1,1," CARD DETECTED!");
     Lcd_Out(2,1,"CARD INITIALIZED");
     Delay_ms(1000);
     
     SPI1_Init_Advanced(_SPI_MASTER_OSC_DIV4, _SPI_DATA_SAMPLE_MIDDLE, _SPI_CLK_IDLE_LOW, _SPI_LOW_2_HIGH);
     Mmc_Fat_Init();
      while(1);
    }
    The code is not yet complete but i don't have a display in the LCD when Mmc_Fat_Init() is being executed. When i remove Mmc_Fat_Init(), got an out in the LCD as shown below

    CARD DETECTED!
    CARD INITIALIZED
    Any suggestion is very much appreciated.
