    Hello Diljith,

    We have an SD Card example for the DK-TM4C129X and the board has an SD card port. This would be the best way to interface an SD card. For the LaunchPad you would need to interface the SD card with an adapter board. This would require additional software that we do not have available, so strongly recommend using the DK if you are looking for a simple solution.

    If you do try and interface with an adapter board, you would still want to reference the sd_card example from the DK board and port it to your LaunchPad. You would just need to modify the example to remove the graphic LCD and possibly adjust a couple GPIO configurations.
