SD Card reading on DUE

[powersoft]

Hello,

I need to read data from a file.
The data format is like

x,y,"Item",magnitude,etc



I have run the self test and all is working perfect.

To read the contence of this file I have tried to use the SDFat library.
As ss I use port 9.
This is not working.

Is the GD2 software able to open the data file, and read the items as above?

BTW the SDFat is working wit the Arduino Uno.

Thanks for any help.
