You are right, inserting the sd into the slot is stopping Server ethernet...

Does anyone knows why about this fact ?

Bump

[Reply #32 on:]

I just spent a painful 20 hours banging on an arduino ethernet shield with an SD card trying to get them to work together.  This thread, ladyada's tutorial - all resulting in arduino crashing when switching between ethernet and SD - nothing worked.

Reason: I was using the Arduino IDE 1.0.1 - everything works when I went back to 1.0

Symptoms - garbage spat out into serial, setup() restarting, not being able to open the files, etc.

I want my weekend back

Mine works fine together using IDE v1.0.1. I use this setup with dhcp for the w5100:

Code:

#include <SD.h>
#include <SPI.h>
#include <Ethernet.h>
byte mac[] = { 0xDE, 0xAD, 0xBE, 0xEF, 0xFE, 0xED };

void setup() {
  Serial.begin(9600);

  // disable w5100 while setting up SD
  pinMode(10,OUTPUT);
  digitalWrite(10,HIGH);

  Serial.print("Starting SD..");
  if(!SD.begin(4)) Serial.println("failed");
  else Serial.println("ok");

  Serial.print("Starting ethernet..");
  if(!Ethernet.begin(mac)) Serial.println("failed");
  else Serial.println("ok");
  // Ethernet.begin() returns with its SPI enabled, so disable it
  digitalWrite(10,HIGH);
}

void loop() {
}

What does the serial monitor say? ok or failed?
I can't give you your weekend back.

Thank you my friend.I had many problems but your setup process worked first time.
