Micro SD shield problem with chip kit Max32

[mmp131316]

Hello everybody i am trying to use chip kit max32 with the sd card shield (this is the shield https://www.sparkfun.com/tutorials/172)
I am making the following connections
chip kit sd shield
pin 50 - pin 12
pin 51 - pin 11
pin 52 - pin 13
pin 53 - pin 4
and pin 10 from the chip kit is connected to the pin 10 from the shield
and of course the vcc from 3.3 v from chip kit to the shields 3.3 v and the ground also
With this configuration and the following code I am receiving the initialization failed message

/*
 #include <SD.h>

File myFile;

void setup()
{
  Serial.begin(9600);
  Serial.print("Initializing SD card...");
 
  pinMode(10, OUTPUT);
   
  if (!SD.begin(53)) {
    Serial.println("initialization failed!");
    return;
  }
  Serial.println("initialization done.");
  
  // open the file. note that only one file can be open at a time,
  // so you have to close this one before opening another.
  myFile = SD.open("test.txt", FILE_WRITE);
  
  // if the file opened okay, write to it:
  if (myFile) {
    Serial.print("Writing to test.txt...");
    myFile.println("lala th city guy.");
	// close the file:
    myFile.close();
    Serial.println("done.");
  } else {
    // if the file didn't open, print an error:
    Serial.println("error opening test.txt");
  }
  
  // re-open the file for reading:
  myFile = SD.open("test.txt");
  if (myFile) {
    Serial.println("test.txt:");
    
    // read from the file until there's nothing else in it:
    while (myFile.available()) {
    	Serial.write(myFile.read());
    }
    // close the file:
    myFile.close();
  } else {
  	// if the file didn't open, print an error:
    Serial.println("error opening test.txt");
  }
}

void loop()
{
	// nothing happens after setup
}

Please give any suggestions regarding why does this work properly !

Thanks for your time. Cheers ;-)

I actually came across a different pinout for the MEGA Arduinos for SPI shields:

You can get this shield to work with the Arduino Mega. For those who have tried and failed, here is how. You do not need to change anything software-wise.
The SPI pins for Arduino Mega are located elsewhere (pin 50-53 instead of 10-13). Simply bend out pins 10, 11, 12 and 13 on the shield so that they do not go into the Mega. Stick the shield in. Put a jumper wire in the headers of pin 10-13 and route them as follows:
Shield pin 10 —> Mega pin 53
Shield pin 11 —> Mega pin 51
Shield pin 12 —> Mega pin 50
Shield pin 13 —> Mega pin 52
This applies to all SPI shields.

Arduino Ethernet Shield MEGA hack

However, these guidelines may not work with the chipKIT MAX32.
