    You have to use command line. Please take a look at the user guide. you can create a batch file and click on the batch file.

    Thank you for your anwser. Now I know how to use nowECC tool. I have another question.
    My IDE is IAR. I use the IAR to produce the file.out and file.hex, which format file should as the input file?
    In the nowECC user guide, the input file should be one of this(Extended Tektronix;Intel Hex;ASCII Hex;Motorola S;COFF;ELF). But in the nowECC user guide,there is also an example:nowecc -i file.out -f021 16M_ADD -o file_ecc.out. The input file is file.out. which input file should I choose?

    When I choose the file.out as the input file, there is no error . If I choose the file.hex as the input file, there is an error.
    My device is tms570ls3137, this is my command:nowecc -i file.hex-f021 16M_ADD -r4 -a -o file_ecc.hex.
    what's wrong with me?

    hi
    user4426369
    check the SPNU491D–April 2014 carefully, it said The output file is of the same format as the input file
    the .hex format is verified by me
    and if you try something like that :
    nowecc -i E:\project0432\project0432\Debug\project0432.hex -f021 16M_ADD -o file_ecc.hex2
    the log file will be
    This is nowECC Version 2.22
    Mapping: F021-16MB

    Ignoring the root name command since the output file is not in COFF/ELF format.
    ECC calculation from 0x00000000 to 0x0000052F
    ECC calculation from 0x00001020 to 0x0000215F
    ECC calculation from 0x00002500 to 0x00011B97
    *** Writing only ECC section to file -> file_ecc.hex4
    No Errors

    then I think now your question is answered.
