NAME

       dfu-prefix - add, check, or remove special firmware file prefix

SYNOPSIS

       dfu-prefix [ -s address | -L ] --add DFU_FILE
       dfu-prefix [ -T | -L ] --check DFU_FILE
       dfu-prefix [ -T | -L ] --delete DFU_FILE
       dfu-prefix --help
       dfu-prefix --version

DESCRIPTION

       The  program  dfu-prefix  can  be  used  to  add, check or remove a prefix used by certain
       hardware manufacturers.  The Stellaris format from TI and  the  LPC  format  from  NXP  is
       supported.

       Note  that  a  standard  DFU firmware file has no concept of a prefix, and a DFU host tool
       like dfu-util passes the prefix on to the device as part of the normal firmware payload.

OPTIONS

       -s, --stellaris-address address
              (in combination with --add) Add TI Stellaris address prefix to file

       -T, --stellaris
              (in combination with --delete or --check) Act on TI  Stellaris  address  prefix  of
              file

       -L, --lpc-prefix
              (in combination with --add or --delete or --check) Use NXP LPC DFU prefix format

       -h, --help
              Displays a help message.

       -V, --version
              Displays the software version.

EXAMPLES

       dfu-prefix --stellaris-address 0x0100 --add firmware.dfu
              Adds a Stellaris prefix with load address 0x0100

       dfu-prefix --stellaris --check firmware.dfu
              Checks the file firmware.dfu for a Stellaris prefix

       dfu-prefix --lpc-prefix --delete firmware.dfu
              Removes a LPC prefix from the file firmware.dfu

EXIT VALUES

       0      Success (also if prefix is missing)
