    Hi,

     I just ran the fatsd_DK_TM4C129X_TI example and I was able to run it. Below is the console message after running. The first time I run the input.txt is not on the SD card and hence the input.txt file is created and then copied to output.txt. The second time the input.txt is already there and copied to the output.txt again.

    Starting the FatSD example

    Drive 0 is mounted

    Creating a new file "fat:0:input.txt"...done

    Starting file copy

    File "fat:0:input.txt" (518 B) copied to "fat:0:output.txt" (Wrote 518 B)

    This is some text to be inserted into the inputfile if there isn't

    already an existing file located on the media.

    If an inputfile already exists, or if the file was already once

    generated, then the inputfile will NOT be modified.

    Prajnith,

    Is the SD card already formatted? If not, can you format it and try again? Also can you try a different formatted SD card?

    Todd?
