Hi,

Can this be used as JTAG dongle?

NikWing:
alright, I'm one step closer ...
I digged in the old hardware oddments of my company's development dept and found an AVR jtag ice mk2
and it's got USB connection, yay (and even an easy to change pinout adapter was attached)
but using google I didn't find any clear information about compatibility with urjtag

can anyone tell me these 2 things: will it work with urjtag and can I safely connect to the DSO's 3V3 pin? (there's also nothing about Vref and Vsupply in the how-to, so I assume they're not connected ... or is UTST or VTST = Vref?)
that would get me a big step closer to dumping the mem ...

Marmad, where did you get the DS2000 b/w response data that extends up to 1 GHz? Was this data posted here on this board?

@neslekkim: I've seen that, along with this: http://sourceforge.net/apps/mediawiki/urjtag/index.php?title=Cables
but I'm still not smarter than before XD

ok, adapter nearly done, I don't know what the UTST or VTST pin is ... I suppose it's Vref?
(Vref is the name of the pin on the AVR jtag connector)
