Version

FatFs R0.13a - October 27,2017

Summary

FatFs is provided as source & pre-built libraries with few modifications to allow for integration with SimpleLink SDK. Unmodified source can be found at Elm-Chan FatFs. Changes are as follows:

• The source directory has been removed. All FatFs source files have been moved up a directory (to third_party/fatfs) alongside documents & lib directories.

• ff.c:

  • Applied patch ff_13a_p1.

• ffconf.h:

  • Set FF_USE_MKFS to 1; this enables the f_mkfs() API.
  • Changed FF_VOLUMES to 4.
  • Set FF_FS_REENTRANT to 1; enable reentrancy support.
  • Defined FF_SYNC_t to (void *); synchronization object type.

• ffsystem.c:

  • Changed synchronization & memory management function implementations to use SimpleLink SDK APIs.

• diskio.h:

  • Added diskio_fxns struct, disk_register() & disk_unregister() in order to allow disk_* APIs to call media specific functions.

• diskio.c:

  • Changed diskio APIs to call media specific functions registered during disk_register().

• Added ffcio.c/.h:

  • APIs to hook FatFs into the TI Compiler's stdio.h APIs.

• Added ramdisk.c:

  • RAM disk layer for FatFs.

• Added utils directory:

  • Miscellaneous utilities for manipulating RAM disk images. These are provided as reference & are not compiled as part of the FatFs library.
