ARDUINO MEGA rev 3

I have bought Arduino MEGA.
I compile SD example, changing pin from 10 to 53, but mi Ethernet Shiedl fail to found the SD card.

The same shield on arduino UNO rev 3 works.

What's must i change?

I have also tried to modify #define MEGA_SOFT_SPI 0 to 1.

Can you help me?
Thanks

There must be problem in ur wiring.
I had experienced also to intagrate mega n lan eth shield.

Wiring all the icsp, then wiring from pin 4(mega) to pin 4(eth) and pin 10 to pin 10 :grin:

Why? The shield's SD SS is hard-wired to pin 4. You don't change the chip select assignments when using the MEGA.

However, you should in setup() still set:
pinMode(53, OUTPUT)

Pin 53 is the on-chip SPI controller SS pin which needs to be set to OUTPUT to work properly, even though pin 53 of the MEGA isn't used by the Ethernet shield.

Change it back.
