Arduino DUE as ISP programmer

Hi guys,

sorry if the question has been already asked but I've looked for an answer on the forum without success.

I've read the ArduinoISP tutorial and I correctly uploaded the sketch on my Arduino DUE.
Then I've done the wiring between the Arduino DUE (the programmer) and my Arduino UNO clone (with an Atmega328P-U, the target micro).
The target micro is powered at 3.3V by the programmer (Arduino DUE).

I connected:
Arduino DUE pin (ICSP) <-> Arduino UNO pin
MISO <-> 11
MOSI <-> 12
SCK <-> 13
3.3 V <-> 5 V
GND <-> GND
10 <-> RESET

And now the questions:

  • should I use the native or the programming port of Arduino DUE?
  • should I modify the ArduinoISP sketch to use the SerialUSB virtual port (I've read it here but it could be outdated....)?

I've tried both the ports and I've tried also to change Serial with SerialUSB without success.
Using the native port and changing the ArduinoISP sketch (Serial with SerialUSB) I get this error:

avrdude: Yikes!  Invalid device signature.
         Double check connections and try again, or use -F to override

avrdude done.  Thank you.

In all other cases the programmer doesn't respond, so I think that I should use the native port and apply the modify to the sketch.

Have I done anything wrong?
Do you see any evident error?
I've checked the wires and done some attempts without success. Any suggestions?
Thank you in advance for your collaboration.
