NAME
       dfu-suffix - add, check, or remove DFU firmware file suffix


SYNOPSIS
       dfu-suffix [options] --add DFU_FILE
       dfu-suffix --check DFU_FILE
       dfu-suffix --delete DFU_FILE
       dfu-suffix --help
       dfu-suffix --version


DESCRIPTION
       The  program  dfu-suffix  can be used to add, check or remove a DFU firmware file suffix, recommended for
       safely matching a firmware file and device.

       Note that a suffix is recommended by the DFU standard, but not required.  A DFU host tool  like  dfu-util
       will recognize the suffix and use it to check that the device is matching, but not transfer the suffix to
       the device.


OPTIONS
       -v, --vid vendorID
              Specify USB vendor ID (hexadecimal)

       -p, --pid productID
              Specify USB product ID (hexadecimal)

       -d, --did deviceID
              Specify USB device ID (hexadecimal)

       -S, --spec version
              Specify DFU specification version (hexadecimal)

       -h, --help
              Displays a help message.

       -V, --version
              Displays the software version.


EXAMPLES
       dfu-suffix --vid 0123 --add firmware.dfu
              Adds  a  suffix matching vendor 0x0123 and product ID 0x4567.  Since product and device ID are not
              specified, they will contain the wildcard value 0xFFFF.

       dfu-suffix --check firmware.dfu
              Checks the file firmware.dfu for a valid DFU suffix

       dfu-suffix --delete firmware.dfu
              Removes a valid DFU suffix from the file firmware.dfu


EXIT VALUES
       0      Success (also if suffix is missing)

       -64    Usage error


LIMITATIONS
       dfu-suffix can not tell a broken DFU suffix (e.g. checksum mismatch) from a non-existing suffix, so  only
       a valid suffix can be removed.
