Welcome

dfu-programmer is a multi-platform command-line programmer for Atmel (8051, AVR, XMEGA & AVR32) chips with a USB bootloader supporting ISP. Most Atmel devices having a USB port come pre-programmed with the bootloader, and this is a lightweight alternative to Atmel's own FLIP/BatchISP program. This is a mostly Device Firmware Update (DFU) 1.0 compliant user-space application.

News

dfu-programmer 0.7.0 released (02 Aug 2014)

This release contains a major internal reworking in several areas

dfu-programmer repository moved to GitHub (25 May 2014)

After many years hosted on SourceForge we have taken the decision to migrate the repository to GitHub. We hope users will benefit from the enhanced support for open source collaboration that is offered by GitHub, and that we will benefit from more user input.

You can find the new repository here.

Downloads will continue to be hosted by SourceForge.

Why dfu-programmer?

The need for this tool came about when I needed to flash an at89c51snd1c chip that had the USB bootloader on it, but the Atmel-provided tool (FLIP) didn't support USB flashing in linux.

After a few days of web searching and scrapping together a windows machine to do the job, I found that Atmel provided a document describing the communications protocol used. I happily spent the next week hacking together the start of dfu-programmer.
