Hi If you have a mutimeter? the 3v3 comes from a diode to the right of the CPU just check for 3v3 its on the cathode end which is marked with a white band

If you are using an active Jtag there should be a red wire on the lead. If it is a passive type(resistors only-non buffered) no Vcc is required.
