I get a swim error [30006] when trying to connect to an unmodified STM-S08-DISCO board (configured for S001J3). I viewed the SWIM signal at pin 1 of the socket and the voltage levels do not look valid.
It is powered by USB and the STLINK LED does flash when trying to connect. The shunt is installed on JP1 and there is 3.3V on pin 4 of the socket.
Attached are the error message and a scope shot of the SWIM signal.
