Okay, my JTAG MK II has stopped working, it appears to be the flimsy cable connecting it to the EVK1104.

So I'm on the look for a new one. I see the MKIII is cheaper and appears to have a more solid connection to the interface. So what is the difference?

Is it better than the JTAG MKII

Thanks for you time...

Well., the cable is still too short for my liking, but it is more repairable than the MkII cable.

The MkIII cable is narrow, approx 10cm long, and has 2 tiny 10-pin, 1mm pitch, sockets at each end.

There is nothing on the 10-pin connectors to grip onto, which means that if you want to remove the connector from the Jtag box or the programming adapter then you must pull the cable. :(

It does program faster than the MkII. :)

Am I right in understanding that it supports the AVR2/EVK1104 dev board?

I've used the MkIII JTAG adaptor to program UC3A0256 and UC3L064 boards, so I'd expect it to work with the UC3A3256 on the EVK1104.

I think the MkIII requires the newer Studio 5 or 6. Does not work with older Eclipse based tools. Mk II will work with both.

Try taking your broken MkII apart. Screws on bottom, maybe under feet; do mot remember exactly. My cable was once loose inside. Nothing to lose!

It would be nice if there was a source for replacement cables.

Here is the spare part at Atmel Store.

I am sure you can get a length of the ribbon cable cheaper.

Or just buy a whole new debugger !
