Why can't I connect the ST-Link/V2 to my target board when the target is self-powered? (using the SWD)
If my board is not powered and the power is provided by the ST-Link, then I can program/erase all the time without issue. However for debugging it is not useful. As soon as I connect the power to the target I loose the connection.Few thingsSWDCLK and...
