I try to program my MCU S08QE8 with cyclone pro but i have error message when i try to connect emulator to MCU

Error: Can not enter background mode.

I check my RESET (Pin 1 of MCU) and BKGD (pin 2 of MCU) signals
On Pin 1 i have 0.4V i thonk OK to do reset.
On pin 2, i have 0.7V!!!
In fact i directly connect PIN 1 of BDM connector from Cyclone to Pin 2 of MCU. Is it correct?
I used an external power to supply MCU but i connect GND of MCU to Pin 2 of BDM connector
 
Somebody ou somewhere can i find some descriptions, explanation about connections between cyclone emulator and MCU S08QE8?
 
thanks
