I am also interested in your soft- and hardware. Can you provide
some further information here?

Anton, please be sure that you have the right timing in your
software for the programming, because some fast JTAG programmer
does not program the FLASH memory the right way and the device will
lose FLASH information within a few months or years. Only the
original Atmel algorithm will provide a good programmed FLASH.
