MKRZERO with W5100 Ethernet modul as gateway, Not working



  • Hi all,
    I am trying to get a MRKZero and a W5100 Ethernet module working as a gateway, but its not working.
    Tried as a first step to get a web-server running on this combo, but the sketch reports "Ethernet shield not found".
    If i get the web-server running i should be able to get the Ethernet gateway running too.

    I seen lots of samples and instructions for the Arduino UNO, but am not able to translate these to the MKRZero.

    I hope there is someone who can help me with this.

    Connections between the Arduino and the Ethernet modul:

    W5100                  MKRZero   
    1    GND                 GND
    2    5V                  5V
    3    Reset
    4    SS                  ???
    5    SCK                 SCK
    6    MOSI                MOSI
    7    MISO                MISO
    8    GND
    9    POE+
    10   POE-
    

    Code:

    /*
      Web Server
    
     A simple web server that shows the value of the analog input pins.
     using an Arduino Wiznet Ethernet shield.
    
     Circuit:
     * Ethernet shield attached to pins 10, 11, 12, 13
     * Analog inputs attached to pins A0 through A5 (optional)
