From stmdude:
Unless you're planning to add another SWD JTAG device on the board, there's no need to even route SWO. SWO is an output, so you can daisy-chain several SWD devices together, so you can use one JTAG to debug several chips in a system at once.
I believe SWO is also for doing trace, so the processor can be observed while the system is running. Check out this video https://www.youtube.com/watch?v=XGmSCVgb6EM.
It's already routed and I'd like to try out trace some time, so I'll leave SWO connected. Should I keep the 100R resistor?
I'll say yes. Closing issue.
Should we have a 100R resistor in series with SWO? See http://community.paxinstruments.com/t/pax-instruments-multilogger/167
