Hello,

does Arduino AVR ATMEGA2560 ADK have a debugger interface, so to use it with my JTAGICE 3 debugger & AVR STudio 5/6, like my ATxmega board ?

Which Arduinos do have such an Interface ?
And which do not have ?
I looked at the hardware photos, at
http://arduino.cc/en/Main/Hardware
, but did not check which jumpers might be the ones for a JTAG debugging interface as the ATxmega board has.

I understand that the "original" Arduino IDE does not support this kind of debugging... and will not, probably.

I consider to buy
http://arduino.cc/en/Main/Arduin...
as there is a local !free! 2-day workshop in nearby Hamburg
Attraktor e.V "2. Arduino Workshop"
http://wiki.attraktor.org/Termin...
in April 21+22th, at a true german Arduino community :-),

and the alternative to buy an Arduino Uno for half the money "just for the workshop" would mean that I might do "less" after the workshop, as I am used to the amount of RAM and Flash space of ATxmega256... ( and from former CP/M Z80 times 25 years ago, LOL ).

It does not much help to come to the workshop with my ATxmega board... ( and for simple experiments, 5Volts technology of ATmega is superior of the 3.3 volts technology of ATxmega..).

Anything specially to consider,
when buying or operating an Arduino, in comparison to my experience with my ATxmega board :-) ?! What I am not used to, what is more difficult ( ok no ASF library... ) ?!

Sincerely
Rolf

As long as PF4/5/6/7 are brought out to header pins (with nothing loading the lines that may interfere) then you should be able to connect up to do JTAG just fine (you may need to check the fuses to check that JTAGEN is enabled and this could require ISP).

This page seems to confirm that the pins you need to access are available as "analog" pins:

Thanks alot,

in this track of Arduino Forum I found a good description what to do:

Arduino ATmega2560 And AVR ONE!
