I'm not talking about modifying the adapters. The adapters have several
signals that (most likely) are directly controllable by OpenOCD and that
you probably have little or no use of on the board, such as nTRST, EMU0 and
EMU1. Any of those could be suitable to use as a board level reset signal
(instead of their intended function). Of course you *will* have to modify
the board, to route the chosen pin to your board level reset line in an
electrically compatible way, instead of to whatever that pin is connected
to today. That shouldn't come as a surprise.

I assumed you had a problem you wanted a solution to, why else would you
post to this mailing list? The way I interpret your first mail, the answer
to your question is yes, it should be possible. But it sounds like you
rather want the answer no, it's not possible.
