if you are not telling to anyone, and without commiting yet to the task, I 
confess that I planned to spend some time to estimate the work needed to add 
swd support to the jlink driver.

unfortunately I don't think this will be possible before 1-2 weeks.

my goal is to add support for swo tracing, similar to the one implemented in 
the Segger GDB Server (a separate socket to telnet into, where the stream of 
tracing bytes is echoed), and to integrate it in the second edition of my other 
project, the GNU ARM Eclipse Plug-in.

the article 1.2 of the Segger manual dedicated to the USB protocol states:

"The purpose of this document is to allow developers of open source software 
such as OpenOCD to write software which uses J-Link as debug interface."

so, even if the manual is incomplete, I think that Segger will not refuse us 
any further information related to the protocol. current experience with them 
was good, they replied in the same day, and I have nothing to complain about.

I have no problem to act in close liason with Segger, if needed.

regards,

Liviu
