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. Ei-
ther 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 im-
plementations of DFU.
OPTIONS
The dfu-tool command takes various options depending on the action. Run dfu-tool --help
for the full list.
