Introduction

This page provides details related to the xilffs library.

The LibXil fat file system (FFS) library consists of a file system and a glue layer. This FAT file system can be used with an interface supported in the glue layer.
The file system code is open source and is used as it is. Glue layer implementation supports SD/eMMC interface presently.
Application should make use of APIs provided in ff.h. These file system APIs access the driver functions through the glue layer.
