    You always need to power up your target board when using an EPB in ICP mode : the EPB uses the application VDD as voltage reference signal to provide the right voltage level on the ICCCLK and ICCDATA pins. The EPB Vdd pin has not been designed to power user's application boards.

    Take care,
