Can I power the board I am using (PineTime DK) from the Segger JLink Plus compact? I have the VTref connected to where the ST-Link V2 3.3v connector was. In that case it provided power and I'm not sure if I can configure the jlkink plus to supply the power.

I see this link J-Link Interface Description (segger.com) which states what it does but not if it supplies power to the board:

This is the target reference voltage. It is used to check if the target has power, to create the logic-level reference for the input comparators and to control the output logic levels to the target. It is normally fed from Vdd of the target board and must not have a series resistor
