There is a tool called avrsvf that can be used to convert .hex file to .svf for JTAG programming of AVR devices. The tool, however, does not support XMEGA devices. Is there a similar tool for XMEGAs?

on this page there is a link at the bottom by someone but it might not be for the one specific device he made it for.
So I didnt find any hex-svf converter for xmega A series. I wrote a little utility (win consol): http://www.vfx.hu/avr/xmegasvf-111029.zip Supported ATxmega128A1 only.
To do: - eeprom read/verify - lock bits read/verify - TCK period handler - all chip erase
vfx.
I am not vfx nor do i know if this actually works, but it seems like using a bootloader + FLIP should work if that program doesn't. Although I assumed you can't load a bootloader onto your xmega. http://www.batsocks.co.uk/readme/XMegaExamples.htm http://www.atmel.com/images/doc8429.pdf
Good luck.

Thank you for answering! What do you mean by "seems like a bootloader+FLIP"? – avakar Feb 26 '14 at 06:42
