Hi, I am working with stellaris Lauchpad based on LM4F120H5QR ( default of launchpad) and using an SDCard as storage device. I started my project using the example of sdcard () and it compiled perfectly. Since we are working with filesymtem we need a specific drive for the sdcard, when we verify the dual-disk-driver.c we didn´t found this definition
#ifdef DISK0_EK_LM4f232
#define DRIVE0_DRIVER "mmc-ek-lm4f232.c"
#define DRIVE0_TIMERPROC
that is needed for us to access the processor. Then my question is which drive is the sdcard example using? And where it was defined the drive to be used?
About my project, the compilation detected the following problems:
**** Build of configuration Debug for project SPI_TESTE ****

And in my code is defined:

#include "inc/hw_types.h"
#include "driverlib/fpu.h"
#include "driverlib/gpio.h"

#include "third_party/fatfs/src/ff.h"
#include "third_party/fatfs/src/diskio.h"

Why are these erros apearing since the includes are well defined? Thanks a lot, best regards
