About:
dfu-programmer is a command-line tool that implements the USB Device Firmware Upgrade class protocol. It allows users to flash, erase, and manage firmware on Atmel AVR microcontrollers via USB. The tool is essential for developers working on embedded systems and hardware projects requiring firmware updates.
Key Features:
  • Command-line interface for automation
  • Support for multiple Atmel chip families
  • USB-based firmware flashing
  • Chip erase and security bit management
Use Cases:
  • Flashing bootloaders onto AVR microcontrollers
  • Updating firmware on custom hardware prototypes
  • Automated manufacturing programming of devices
Alternatives:
  • avrdude – avrdude supports more programmers and protocols but dfu-programmer is specialized for USB DFU devices
  • atmel-dfu – Atmel's official tool is GUI-based and platform-specific, while dfu-programmer is cross-platform CLI
