Just a heads up...be careful out there if you want a genuine Atmel AVR JtagIceII! The cloners have knocked off the case also now, but if you look carefully at the picture you will notice some differences

the target cable, the labeling on the case....

Ebay - NEW Emulator AVR JTAG ICE USB Atmel mega tiny w/ ISP Item number: 320114180780

http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=320114180780&ru=http%3A%2F%2Fsearch.ebay.com%3A80%2Fsearch%2Fsearch.dll%3Ffrom%3DR40%26satitle%3D320114180780%2B%26category0%3D%26fvi%3D1

doesn't mean its a bad product...but.....

wish the cloners would do something creative like an injection molded case for the Dragon rather than trying to knockoff the JtagIceII.... :twisted:

"AVR JTAG ICE (...) tiny" sounds like false advertising to me.

Now, "AVR JTAG ICE (...) w/ ISP mega tiny" would have been honest but indirect.

Hope people don't fall victim to this hoax thinking it actually allows ICE of any 'tiny' parts.

On the subject of Clone JTAG's does anyone have any reccomendations?

I have a Dragon but I am using a lot of mega64's and can't bear the idea of going back to load/debug/load/debug style programming.

PS sorry bluegoo for the subject hijack!

I have used a homemade unit for a couple of years with the M64 (on veroboard), seems to work well so far.

Hi John,

I've thought of building/modifying the IsoJtagIsp from FloppySponge.

But i'd like to be lazy!

Well then buy one :) I believe that there are some for around US$40.00 at ERE in Thailand?? Some freaks use them successfully, I built mine on an afternoon of a long weekend when I wanted one NOW..for some reason which I can't remember..must be senility, I was going to buy one but then Atmel was kind enough to send me a Dragon last year and as most of the chips I use can be debugged by it (except the M64/128) I don't really need one. I have also an AVR910 programmer for updates so I didn't build in the 2313 for upgrades.

Well, if Atmel allowed the dragon to debug all of the devices, including the mega128 and friends, it would kill all cloners. Or atleast they could opensource it!!!

I had been using satisfactorily JTAG clone from Olimex. I'm pretty happy with Mega128/64/32. Old MKI clone, though.

Let's be clear, I don't have a problem with people using the JTAG clones, as long as they know whay they're getting before they buy.

The eBay listing that daqq first mentioned seems misleading to me (it might lead an uninformed buyer to think they're getting the mkII functionality) because of the unit's appearance, and the listing's title.

Mmm...

$59 AUD for a JTAG I clone from ERE inc postage
$242 AUD for a JTAG II + STK500 from digikey inc postage

-$100 AUD to sell the STK500 on e-bay....
=$142 AUD for a JTAG II!!! sold!

OK i'll have to wait a few weeks but with the dollar so high it's worth it!

I just wanted to remind, that a MKI Ice clone can be made from a spare Butterfly. There is a patch project posted to the academy.

Can not get much cheaper than that for a clone.

Basically, a mkI clone can be made from a spare ATmega16 on a
breadboard that is clocked by a 7.372 MHz crystal. Only few
wires needed in addition to that.

But the butterfly solution is really cool!

Holy hell - crafty devils. I've emailed avr@atmel.com as a FYI - perhaps they'll get a kick out of it, or (less likely) find the source and shut them down. This is why all my designs will be locked in a bank vault somewhere, never to see the light of day...

Just a question: The dragon cannotr JTAG Mega128 and friends because of hardware issues, or is it only locked in software. IMHO if atmel released the dragon with full abilities it would kill all cloners, because: all programing and debuging modes of all avrs for $50? Not even the chinese could beat that.

dean: Well, if you actually release the hardware it is AFAIK not a problem to copy it regardless of the open/closed sourceness of your design. Just look http://www.mcu.cz/modules/news/a... and this is just one of a lot.
