Hi Chuck,

Sorry to hear that your Dragon had a fault.

I think getting such a cheap board repaired may cost more to you in labour and parts than simply buying a brand new one. Dragon costs about $45 so I think you are better off buying a new one rather than getting it repaired.

Getting a new one may also be faster so your work will not be interrupted for long.

Regards,
Cagri

My AVR Dragon seems to have died.

I programmed one board, swapped boards to program the next one and noticed
that Studio reported an error and the LMxxx regulator on the board was
getting hot.

Both boards have been programmed many times in the past.

Now when I connect the Dragon to a target board it is apparently shorting
Vcc to Gnd.  

The problem is on the Dragon board itself (as opposed to through the USB
cable) because it happens even when the USB cable is unplugged from the
Dragon.

Is there anyone that might have the capability to repair it?  I’m willing to
reimburse reasonable costs…
 
Cheers,

I have a couple of dead Dragons. Love the concept but something is delicate. While a JTAG ICE mk-II is more expensive I don't seem to blow them up. Don't think I smoked the Dragons, perhaps I can zap their firmware back to life with the mkII?

The ECROS ICE-Cube is another good one. Takes a licking and keeps on ticking. But not the Dragon.

Yea, I'm afraid you're right.  If I had the schematic there would be some
hope but I'm shooting in the dark.

Luckily I'm not at a critical point like I was when I switched from
ATMega32's to ATMega1284p's and I had to get the Dragon because my trusty
ECROS Ice Cube wouldn't handle them.

That time I paid for overnight shipping on the Dragon because I was in a
bind - the shipping cost me almost as much as the Dragon!  :-(

My board was a newer model with slightly different parts placement but
similar.  I removed the switching PS chip and installed the wire but no go.
The Dragon board still kills the 5v Vcc on my board when I plug in the
Dragon.

What is the advantage of the mk-II over the Dragon (other than the fact that
the Dragon seems fragile ... which may be enough in itself)?

Yup, my ICE-Cube is still alive and well and usable for my ATMega32 boards
but not for the ATMega128p boards :-(

Atmel should hire ECROS to consult on an improved Dragon design :-)
