[bug #41878] AVR Dragon JTAG: ATxmega256A3BU hangs, when programming or reading device signature

When reading device signature by issuing avrdude -px256a3bu -cdragon_jtag or programming, ATxmega256A3BU hangs and does not execute the written code.

If I reset the chip after accessing it through AVRDUDE, ATxmega256A3BU works without any problems.

I use AVRDUDE 6.1 on Linux machine (openSUSE 12.3). Feel free to ask for more details, as I am not sure what info should I provide.

I have also Windows 7 machine with Atmel Studio 6.1. There I can program ATxmega256A3BU through the same AVR Dragon normally: the code gets executed right after finishing programming.

This issue was migrated from https://savannah.nongnu.org/bugs/?41878

Can you please run with -vvvv (four options "-v"), and attach the stderr output as a file to this bug report?

Not so sure if this is linked to #365

Edit: probably not related.

This may be related to #310.

I'm not able to reproduce this issue, so I think we can close it.
