JTAG/SWD Debugging for the Teensy

[est]

I see that this wish has been posted by others too, so I would like to add to it:
Why not enabling JTAG/SWD debugging for the Teensy?
There would be space for holes in the layout to populate by the user a standard JTAG/SWD header (2x5, e.g. http://ch.farnell.com/samtec/fts-105-01-l-d/stecker-127mm-durchloch-10kont/dp/1667728).
Plus if necessary some cut traces to the MINI54TAN.

As I did not wanted to wait for such an extension, I did it myself with soldering wires and cutting traces:

and with this I can do SWD (or JTAG with two extra wires) debugging

Thanks for consideration!
Erich

Excellent!
And the document ends with a very good suggestion on having an SWD/JTAG connection site on future Teensy boards.

While I perfectly agree to and support the idea of having access to SWD/JTAG, during the last few days, another debug option arose, that can be implemented only in software. See this thread: http://forum.pjrc.com/threads/26358-Software-Debugger-Stack?p=52434#post52434
