Hi,
after not using AVR Chips for some time´I tried to fire my Olimex JTAG ICE again under Windows XP and AVR Studio 4 SVP4, but no deal. The system does not recognise the JTAG ICE, the drivers seems to work correctly. Any Ideas?
Thx, Fried

Been to Olimex and looked for updates?

As of January 15, 2018, Site fix-up work has begun! Now do your part and report any bugs or deficiencies here

No guarantees, but if we don't report problems they won't get much of  a chance to be fixed! Details/discussions at link given just above.

Yes, I've been there but didn't find anything useful except some remarks from other users asking about the same problems with their Olimex AVR-USB-JTAG, and no solutions or even reaction from Olimex.
Seems to be some crappy reversed engineered design. It's always the same, buy cheap buy twice..
So I'm going to get the Mk2 from Atmel, and be hopefully out of trouble for some time..

Received my JTAGICE Mk2 from Atmel today, all works very well.
Bye Olimex, never again!

> Seems to be some crappy reversed engineered design.

Sure, this was/is commonly known. All these cheap JTAG ICE mkI clones
were simplified circuits of the original Atmel ICE. Most of the time,
the level shifters have been omitted (they consisted of a truckload of
"chicken food" on the mkI JTAG ICE), some of the clones didn't even
connect the target reset circuitry. All these clones just copied the
circuitry, but didn't even try to understand the (proprietary) Atmel
firmware: they just implemented a bootloader talking AVR910 protocol,
so the original Atmel firmware loader (avrprog.exe) would talk to it,
and happily flash the original Atmel ICE firmware into the clone.

That's also the reason why all the clones now stop working on more
recent AVRs: Atmel abandoned development on the mkI firmware, and as
the clones never wrote their own firmware (the JTAG debugging protocol
is considered Atmel proprietary anyway), they cannot even try to
integrate support for more recent AVRs.

As for repairing your Olimex ICE, it's probably nothing more than
re-flashing the firmware using the bootloader.

yes, Jörg is right, reflashing its firmware will make it work, I just did it.
