Re: [Gumstix-users] JTAG for connex board?

[Heilpern, M. <mar...@au...>]

I guess it isn't exactly the wiki, but
http://pubs.gumstix.org/boards/GUMSTIX/ has a link to
http://pubs.gumstix.org/boards/GUMSTIX/testpointlocations.txt, which
contains (among other things) the signals needed on the bottom (92 pin
header side) of the connex, to bring out JTAG.

I don't have the exact signals I used for making this work; sorry. (On
the other hand, Verdex with the JTAG breakout works well with little
need for a soldering iron.) My only advice: tread lightly, because a
mistake can fry your connex.

I've seen it mentioned about attaching wires to the bottom of the=20
connex, however I've not actually been able to find anything in the Wiki

about that.  For example, I just searched for JTAG on the Wiki, went=20
through each of the pages JTAG is mentioned on, and checked for each=20
reference to JTAG and none of them tell you how to add one to the=20
Connex.  The only thing close I can find is the reference to the old G=20
rev boards and the Tweener.

Can anyone provide a direct link to the information I'm looking for?

Thanks

David
