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 de-
vice 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 re-
turn 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 han-
dles 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.
