Client for AVR-based JTAG programmer: https://github.com/ClusterM/clujtag-avr

It's based on Lib(X)SVF (http://www.clifford.at/libxsvf/) so you can use it to flash SVF or XSVF files. Use MinGW (www.mingw.org) to compile it for Windows if need. Linux users are welome too.

How to use:

Usage: clujtag [ -v ... ] -p portname { -s svf-file | -x xsvf-file | -c }

• -p portname - use specified serial port for communication with programmer (COMxx for Windows and /dev/ttyxxx for Linux)
• -v, -vv, -vvv, -vvvv - verbose, more verbose and even more verbose
• -s svf-file - play the specified SVF file
• -x xsvf-file - play the specified XSVF file
• -c - list devices in JTAG chain

Examples:

>clujtag -p COM16 -c
