Cannot make a SD card reader working with Arduino Due

Hi, I'm triing to program a datalogger function into an S-function in Simulink R2017a for an Arduino Due but impossible to make it working.

My program is working good if I use it with ArduinoIDE, It was also working with simulink on an arduino UNO. I have the last simulink package

I have tried to use lot of differents library (No need to select some libraries in ArduinoIDE but it's needed in simulink and finaly I have taken the last Libraries I find on the computer (SD.h; SD.cpp; File.cpp; SPI.cpp;SPI.h). Before I had an error on SPIsetting when triing to compil with other library but know it's ok. My program run good but it never see the Sd card.

My code here:

Libraries:

 #ifndef MATLAB_MEX_FILE

 #include "SPI.cpp"
 #include "SPI.h"

 #include "SD.cpp"
 #include "SD.h"

 #include "file.cpp"

 const int chipSelect = 10;

 File logfile;

 #endif

Discrete Update:

 if (xD[0]!=1) {

    # ifndef MATLAB_MEX_FILE

    // initialize the SD card
    if(!SD.begin(chipSelect)){
        // fail if card is not present
        return;
    }

    // create a new file
    char filename[]="LOGGER00.CSV";
    for (uint8_t i = 0; i < 100; i++) 
    {
        filename[6] = i/10 + '0';
        filename[7] = i%10 + '0';
        if (! SD.exists(filename)) 
        {
            // only open a new file if it doesn't exist
            logfile = SD.open(filename, FILE_WRITE);
            break; // leave the loop!
        }
    }

    logfile.println("Time,Sensor1");

    # endif

    xD[0]=1;
}

Outputs:

 if (xD[0]==1){

    #ifndef MATLAB_MEX_FILE

    // log milliseconds since starting
    uint32_t m = millis();
    logfile.print(m); // milliseconds since start
    logfile.print(", ");

    // log sensors
    logfile.print(sensor1[0]);

    logfile.println();

    logfile.flush();

    #endif

 }

Before to have #include file.cpp the simulation was blocked at time 0 but know all the other function work fine. To see where the problem I had an output status and I see that the program was doing a loop at the begening:

    // initialize the SD card
    if(!SD.begin(chipSelect)){
        // fail if card is not present
        return;
    }

I think it's a bug on the arduino library on simulink but I will be really happy if you have a solution. I was searching for 7days and today I think I had test all I can.

Thank you all

Regards
