Compact Flash File System - Ben Popoola - 16:11 05-01-04



I need to port a compact flash file system to Forth to use in an 
embedded FPGA project.

Can anyone provide me with C source code or any other documents that I 
can get started with. A useful document would be the file structure of 
DOS file system.


Cheers
Ben

CompactFlash is a storage medium.  The data on a CompactFlash can be
accessed 3 different ways.  There are many possible filesystems that
can be put on that CompactFlash.

Perhaps you should figure out what you need, the steps to get there,
and then ask questions about each of those steps after searching
Google and Google Groups.

Google for fatgen102.pdf .
It is a "Hardware White Paper" from Microsoft
entitled "FAT: General Overview of On-Disk Format"

That should get you started on the file system
structure.

Hi Ben,

 I'm going open source by the end of January with the a project
 that has the FreeDOS filesystems (FAT16). If you are in a hurry
 though, send me an email an I will send you the source files
 and a project compiled for MSVC.

A filing system in Forth is supplied with our Forth 6 cross
compilers. It is being used with CF cards. For more details,
see our web site or contact me directly.
