I have a problem using the STLink/v2 via SWO interface when NRST is not connected. We recently switched our hardware layout and NRST is no longer on the connector of the board. Now CrossWorks won't let me connect with the MCU reporting something like "can't stop provessor". Erasing the chip via terminal works though. If the STLink is already in "Connected" mode when attached to the board debugging works without problems.
I found this thread where the possibility of a soft reset is discussed:
I'm unable to find a file where I could configure a soft reset. Is this possible with CrossStudio?
