Hello, I would like to write an application using the internal storage of the K64F (512KiB, or even better 768KiB if possible) as USB MSD.
The intended use is for the user to move files to the MSD, which the program will then use.
Enabling USB MSD compiles okay it seems, but setting
//#define SDCARD_SUPPORT // SD-card interface
#define FLASH_FAT // FAT in internal flash
//#define SPI_FLASH_FAT // FAT in external SPI flash
#define FAT_EMULATION
Does not compile.
I get:

Is there a specific way I can accomplish my goal easily?
And is the source code for the
USB-MSD with SD card, internal Flash disk and external SPI-Flash disk
example on the Kinetis landing page available (So I can strip out the SD-Card and SPI-Flash code)?
