w5500 EVB and Arduino nano

Hi guys, I want to interface Arduino(I tried also with a Leonardo) nano with the Wiznet w5500 evaluation board. I've only one problem: when I plug the Arduino nano SPI wires on the w5500 I can see from the serial(TeraTerm) that,even with a blank sketch running on the Arduino nano, the IP,Gateway,DNS,MAC and port are reset to 0. If the Arduino nano is unplugged all the parameters are assigned correctly. It clearly seems an hardware pinning related problem, I checked 20 times the pinning and the electrical continuity between cables. The project is really similar to the Arduino ethernet shield, the evaluation board is shield compatible, so the ports that I'm using are 10(SS),11(MOSI),12(MISO),12(SCK), GND. Any suggestion, why is resetting? Thanks!

You can't use D11 to D13 for SPI on a Leonardo. The SPI data lines are available only on the ICSP pins.

With the nano, I don't know exactly what this means. This is from the nano hardware page;

SPI: 10 (SS), 11 (MOSI), 12 (MISO), 13 (SCK). These pins support SPI communication, which, although provided by the underlying hardware, is not currently included in the Arduino language.


Ok thanks, I want to understand clearly that sentence, it’s really confusing, how can i make an SPI communication then?
