I'm using a Sparkfun Ethernet Pro V11 (discontinued). This card has a AtMega328 on it but does not have an SD card like most of the new shields. I have an Adafruit Sd card that works very well when connected to my UNO, using the Sd.h library and the cardInfo example.
When I try to connect the Sd to my Sparkfun Ethernet Pro, I get an initialization failed error.
I have tried using several different pins as the chipSelect but none work.
I know that the Ethernet shield uses pin 10 to select the onboard Ethernet chip and I even pulled it HIGH to make sure the internal chip was not selected.
Can someone help?
Thanks
Robert
