I have a sparkfun Mega Pro 3.3V(https://www.sparkfun.com/products/10744) and a sparkfun SD breakout board (https://www.sparkfun.com/products/544). I followed the tutorial on adafruit to connect my 2gb SD card to the arduino, and used their SD library,  But I always get "Initialization Failed" in the serial monitor. I verified the breakout board is getting power and all pins connect to the proper pins on the arduino, but I still get this error. The card was formatted to FAT16 by the formatting tool adafruit linked to. I read online that you have to change a line on the "Sd2card.h" file. I changed

Code:

#define MEGA_SOFT_SPI 0

to

Code:

#define MEGA_SOFT_SPI 1)

and it still doesn't work. I also edited the pin numbers on the "Cardinfo" code to

Code:

pinMode(53, OUTPUT);   const int chipSelect = 53;

 What else can I try?

You say you followed 'tutorial on adafruit'.... and 'all pins connect to proper pins on arduino'........ The adafruit SD libraries work fine....


Confirm your connections thus :-
