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.
