Try http://www.utasker.com/kinetis/FRDM-K64F.html

There are binary files that allow reading/writing the SD card on the FRDM-K64 (on DOS like interface via UART, USB-CDC or Telnet) and also for USB-MSD-SD card and FTP and web-server. The code is available on GitHub (uTasker project) and it can be fully simulated in Visual Studio for study purposes.
The same is also possible with memory stick (or both memory stick and SD card at the same time).

Dear Anju Antony,

You can also download the fatfs sdcard example from the SDK (https://mcuxpresso.nxp.com/en/welcome) this example implements the "create directory/read directory/create file/write file/read file" operation.

Best regards,

Felipe
