А это не подойдет? The included LFM archive file contains the 'C' source code for Intel LFM
(Linear file system [LFS] File Manager), a reference code version of Intel's flash media manager for LFS. LFS is a PCMCIA defined partition format that is well suited for simple flash media managers (such as LFM) and execute-in-place(XIP) operation. The LFM reference code allows you to implement a simple, custom flash media manager/file system in your application without having to expend the effort to develop all of the Flash file system code. It handlesgeneral flash file manager functions including but not limited to: File Open, File Close, File Delete, File Seek, Reclaim, and Power-off Recovery. You need only code the low level hardware specific interface and the high level interface to your code and/or your operating system.
