  • Greetings,

    The yellow LED indicates your target board is powered up. Is your board connected with power?

    Pin 3 is a no-connect. The configuration on BDM is:

    Pin 1 = BKGD
    Pin 2 = GND
    Pin 4 = RESET
    Pin 6 = VDD

    So you should measure VDD and GND to check for any short. The most popular issue is people do not connect the VDD line, however this is a necessary connection as the multilink has no reference voltage to know highs and lows in the BKGD and RESET lines.
