J-Link SWO Viewer functionality is poorly documented and I have several questions:
1. Is it possible to run multiple channels views simultaneously ? CMSIS mentions this useful cortex-m feature but it seems like j-link polling mechanism will not like it.
2. How target could check for swo "connection" or at least for some kind of being under j-link control before trying to send to ITM ? Currently my firmware doesn't and simply hangs trying to send output when j-link isn't connected.
Thanks in advance,
Artem
