I was working with dragon and suddenly one fine morning it stopped getting detected by the PC and some component on the edge got heated very badly
(i suspect it was diode by ST)

Is their a way to get the Dragon repaired or to repair it ourselves???

How is the reliablity factor of Dragon compared with other tools like JTAGICEMKII or STK500 or ISP programmer? As this is not the first dragon to die but other died of some different reasons.

Regards, Kapil +) ISP lines on MEGA128 NOT mapped on SPI +) Tiny4/5/9/10, Isolate Reset line from ISP before connecting it to +12V

if you would have done a search on AVRdragon you would have found tonns of articles that would have described your question.

also a search on "dragon slayer" would give you lots of info.

If you are lucky the original dragon slayer is still in the air and might give you some feedback on his yourney to get the dragon caged and secured for use.

regards

Yes, Dragons like to die. A common failure mode is the power regulator. Search the forum.

Stealing Proteus doesn't make you an engineer.

I've found my JTAG mkII to be very resilient to my daily abuse. Unfortunately, debugWire is somewhat glitchy with an ATtiny861 (I sometimes need to use HV programming to reset the fuses to something sane). Other than that, I have been extremely pleased with the mkII. My STK500 has also taken my abuse like a champ.

Math is cool.

Just to validate: I've fixed two dragons using that method. You essentially bypass the regulator converting the 5V from USB into the 5V used by the AVR's. For some reason Atmel decided they need that regulator, but undersized it. Both concerned Dragons are living on now.
