How to change the Arduino-debugger to JTAGICE mkII

Hello, as as an arduino newbie I tried to change the debugger to my JTAGICE mkII... without success.

When I create a "normal" project I can debug without any problems, when I use an arduino sketch I'm not able to switch to my JTAGICE mkII - though I set tje JTAGICE mkII to my debugger with debugWire.

But I get always this message:

Minimum Memory Usage: 201 bytes (10% of a 2048 byte maximum)
Uploading to I/O board using 'COM9'
avrdude: stk500_getsync(): not in sync: resp=0x00

How can I change this to my mkII???  Undecided

Hello,

Arduino does not so easily support debugging using native debuggers in Atmel because Atmel does not understand .ino source files. 

This is one reason why we have the serial/usb debugger. Whilst serial/sub debug does not currently provide some of the in-depth debug views provided by atmel studio it does have other benefits.

However you want to know about native debug so I will not dwell on the serial/usb debugger.

The best way to make this work right now (we are working on a better solution) is to click build on your sketch project. The latest beta will copy the .elf into the sketch output folder sketch/debug or sketch/release (the location depends on your project config as with normal atmel projects).

After you have built the .elf using the Visual Micro Arduino compiler click "File>Open object file for debugging". This will create a new atmel solution that will allow normal Atmel "start with debugging".

I believe that "Debug wire" will only work on an Arduino board if you have hacked the reset pin or removed the cap. You will read more on the web about this.

Does this make sense, sorry it's not slick yet but this is a historic problem between arduino and atmel and nothing to do with Visual Micro which currently ensures a 100% Arduino compatible project structure.

thank you very much!!!
You gave me the necessary and very helpfull information,
I did it step by step (and my arduino board was already modfified with a switch - so there is no problem with de debugwire)

and in fact: it's all okay and working fine!

All made sense!  Wink and I'm happy !

thank you very very much, even this is not a very slick solution but it works fine for me.  Cheesy

and ... of course I'm looking forward a seamless solution, but your solution will do fine!!! and it is quite good  Smiley

Great thanks for the feed back. 

It will be very useful to have you testing the new stuff when it is available. If you can please register for email notifications of new releases here http://visualmicro.codeplex.com/releases/view/105966

You will be emailed new features and will see notes about atmel native debugging when available

done..... I will keep you informed Wink

the debugger looks good, but crashed to times single-stepping through the "library-code" (eeprom) and finding references (shift-alt-F). I hope these are exceptions.... for today... Grin

I hope so too. Did you try the Atmel 6.2 beta? 

If you find time to leave a review in the atmel gallery it will be appreciated but not critical  Smiley

Thanks

Yes, I'm using v6.2 (6.2.993 beta)
I was a visitor on the 'embedded-world n�rnberg/germany' and I have seen this beta - and now I'm using it... but btw I have also v6.1 installed... atmel said v6.2 is much better for debugging, but I missed further asking about this statement.

Sorry to ask but I want to make some wiki documents showing how to add a reset switch. An easy way for people to switch between debug-wire and normal arduino upload.

Do you have a solution that you think will be useful? To disable the capacitor but then be able to enable again?

... yes .. I have an very easy solution.

I was cutting the "Reset" line, soldered two wires on to the board (to the new created reset points) and soldered a switch on the other end of the two wires and fixing this switch with hot glue to a connector... Simple, but you need some skills to do this.

For the Arduino Uno it is easy... and you can switch the two modes.

That's a good idea. I was trying to work out how to replace the capacitor with a switch. new reset points is much better!

How does the Uno switch? Using the solder pads or something even easier?

I used the solder pads, on one connector you can one pin of the reset (pin 3 on connector POWER), but this is only one pin of the two. The second pin you need is not available on a connector - so I decided to solder to wires to the "opened" pads. Maybe other boards are better to modify than the arduino Uno Rev.3. but I don't know this at the moment and I'm right now up the 3rd. day with the arduino and the VM....

This is great thanks. Most users have the boards you have so they will make great examples. Thanks again.
