SD interface = SPI interface.
You should be able to use the following mbed code for your project:
https://developer.mbed.org/teams/mbed/code/SDFileSystem/
// Access the filesystem on an SD Card using SPI
#include "mbed.h"
#include "SDFileSystem.h"
// change the port pins to suit the SPI port pins on your target board
SDFileSystem sd(p5, p6, p7, p12, "sd"); // mosi, miso, sclk, cs
int main() {
FILE *fp = fopen("/sd/myfile.txt", "w");
fprintf(fp, "Hello World!\n");
fclose(fp);
}
