       dfu-tool - dfu-tool


       This manual page documents briefly the dfu-tool command.

       dfu-tool  allows a user to write various kinds of firmware onto devices supporting the USB
       Device Firmware Upgrade protocol.  This tool can be used to switch  the  device  from  the
       normal  runtime  mode  to  `DFU  mode'  which  allows the user to read and write firmware.
       Either the whole device can be written in one operation, or individual  `targets'  can  be
       specified with the alternative name or number.

       dfu-tool  uses  the libdfu shared library to perform actions.  All synchronous actions can
       be safely cancelled and on failure will return errors with both a type and a full  textual
       description.   libdfu  supports  DFU  1.0,  DFU 1.1 and the ST DfuSe vendor extension, and
       handles many device `quirks' necessary for the real-world implementations of DFU.

       Additionally dfu-tool can be used to convert firmware from various different  formats,  or
       to  modify  details  about the elements, images and metadata contained inside the firmware
       file.  For example, you can easily convert DFU 1.1 firmware into the vendor-specific DfuSe
       format,  convert  a  Intel  HEX file into a raw file padded to a specific size, or add new
       copyright and licensing information to an existing file.  Fields such as  the  vendor  and
       product IDs can be changed, and the firmware elements can be encrypted and decrypted using
       various different methods.  Merging two DfuSe files together is  also  possible,  although
       specifying different alt-setting numbers before merging is a good idea to avoid confusion.

       Although  dfu-tool tries to provide a large number of easy-to-use commands, it may only be
       possible to do certain operations using the libdfu library directly.  This is easier  than
       it  sounds, as the library is built with GObject Introspection support making it usable in
       many languages such as C, Javascript and Python.  Furthermore, using the library is a good
       idea  if  you  want  to perform multiple operations on large firmware files, for instance,
       converting from an Intel HEX file, padding to a certain size, setting  vendor  and  adding
       licensing information and then saving to a remote location.
