DFU (Device Firmware Update) is a standard mechanism provided by most microcontroller manufacturers to allow firmware updates of the device's non-volatile memory. STMicroelectronics has developed and made available for free their DFU tool, DfuSe (DFU file manager for USB devices), to allow the creation and management of firmware images specifically for STM32 microcontrollers located on USB devices.
DfuSe is an intuitive graphical user interface that allows users to easily create, modify, and program DFU files. DFU files can be used to update the firmware of an STM32 microcontroller-based USB device in the field, without requiring a debugger or specialized programming hardware. It supports multiple transfer modes such as bulk, interrupt, and isochronous, and can transfer any data type ranging from firmware binaries to control data.
Supported operating systems include Windows, Linux, and Mac OS X. DfuSe is compatible with various STM32 microcontrollers including STM32F4, STM32F7, and STM32L4.
DfuSe simplifies the firmware update process for developers and can greatly reduce the time required to update STM32-based USB devices in the field. Its ease of use and compatibility with multiple operating systems make it a popular choice among developers working with STM32 microcontrollers.
