Hello 
everybody,
    is there 
a file system available for eCos?
TIA,

Hi Maurizio,

Currently there are no open source file systems supported by eCos. This is
certainly something that we intend to remedy in the near future. Third
parties such as EBS (www.etcbin.com) can provide Flash, PCMCIA and IDE fs
support that may meet your needs.

Paul.

True.  As our copyright notice says, if the GPL on code that we wrote
is a problem for someone, come talk to us about it-- maybe just buy us
a beer!  Obviously, we can't change any GPL on code we didn't write
(eg Linux filesystems), but of course the BSD ffs is not GPL'ed.

The OSKit ( http://www.cs.utah.edu/flux/oskit/ ) would probably be a
good place from which to grab a filesys.  Since the main point of the
OSKit is to produce components that are easily usable in *other*
operating systems, it should be relatively easy to get one of its many
file systems to work with eCos.  You'd have to write the glue code to
map the normalized OSKit execution environment to the eCos one; there
are examples and lots of docs, and we'd help out if needed.

File systems in the OSKit's current bag of components include all the
Linux-supported filesystems (ext2, msdos, vfat, and iso9660 have been
tested), the standard BSD "ffs" filesystem, and a simple memory
filesys.  Since the OSKit wraps essentially unchanged code from the
original OS's (except for the memory fs), its file systems are more
reliable and speedy than if we'd been foolish enough to reimplement
them.

But they are probably also GPLd then. This may be a problem for some
people since eCos is linked to the application code and thus require
the application code to be GPLd as well.
