MCP5777C-416DS power supply

I am trying to get along with the MPC5777C family device. I have the daughter board as stated in the topic (intending to use it as a standalone solution). I have put the controller into the socket, matching the 1st pin (ball on the package) with the small triangle on the socket. I would be grateful, if you could give me answer to the following problems:
1. Using 12V 500mA transformer-based power supply, I am having the following results on the board: the D5, D6, D7 (5VSR, 3.3V, 1.25V) LEDs light, the D512 LED lights, and the D8 diode blinks rapidly couple of times, then all diodes go out. I have not found any particular information on the diodes behavior, but I am almost sure, that the board is not powered properly.

2. What kind of high density connectors should I use in order to get to the chosen pins of the controller in standalone mode?
I can give more information on jumpers setting, if required.

Best regards,
