    Jose,

      Your issue sounds very similar to this E2E post, which covers the SDSPI. Let me know if this solves your problem.

    Thanks Bob for your response, i tried change the connection from MOSI to MISO in the RFD22130 RFduini microSD Shiel, but i get the same error on Putty.

    the code fails in this part

    /* Open file for both reading and writing */
    src = fopen(inputfile, "w+");
    if (!src) {
    Display_printf(display, 0, 0,
    "Error: \"%s\" could not be created.\nPlease check the "
    "Getting Started Guide if additional jumpers are necessary.\n",
    inputfile);
    Display_printf(display, 0, 0, "Aborting...\n");
    while (1);
    }

    i dont know what would be the problem, i I went back and checked that all pins and jumpers were correctly set up and I think that they are.
    So there any way to test the SPI Connection??

    Thanks in advance

    I found the solution of my problem,

    it seems like the SD must be formated to "FAT16" or "FAT322 in order to work, if your SD cad have any different format, the example wont work.
    my SD card was in "exFAT" that why it does not work.
