 while(error == 1)

  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.
