NAME

       dfu-tool - write firmware to DFU devices

SYNOPSIS

       dfu-tool [CMD]

DESCRIPTION

       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.

       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.

OPTIONS

       The  dfu-tool  command  takes  various options depending on the action.  Run dfu-tool --help for the full
       list.
