dfu-programmer: 0.5.1 Released (SourceForge)
A linux based command-line programmer for Atmel (8051 & AVR) chips with a USB bootloader supporting ISP. This is a mostly Device Firmware Update (DFU) 1.0 compliant user-space application. Release 0.5.1 follows release 0.5.0. A command line option was added to support the AVR32 trampoline (so dfu-programmer ignores any code that might exist in the bootloader code space)."
