FAT32 for embedded
basically for logger of information.
The CPU used is a LPC2294
The implementations that i look (freeDOS, eCos, Rtems) seem be too much
complex for my application.
can somebody give me information about some free implementation more
simple?
Thanks in advance

Try searching the message archives yet? There has been a lot
discussed regarding SD/MMC filesystems in the recent past.

or the one from ELM at http://elm-chan.org/fsw/ff/00index_e.html
Both of these are targeted for SD cards, though you could modify them to
suit. I have been using EFSL with some success, but there are a number of
bugs.

I need a simple but fast access to a IDE, so, the ELM seem be good. I
will test it.

create one large file, figure out where it's located and just write
to that area. I did that for an MMC logging system and it works
great, very little code needed.

Can you tell us what bugs, you found in EFSL.
I have tested it for 6 months, and putting it on one of our product.

as bug reports to the sourceforge project, so look for the details
there.
One that I haven't been able to nail down yet, is random file
corruption, even if not writing to the disk. This could be a
hardware problem, but as yet, I have found no explanation for it.
If you have been using the library for 6 months, then probably there
are few bugs in the features you are using. Obviously I am using
different features, as I have had to fix the code in a couple places.

OK, its about appending to a file. I am not appending any file so need not
worry.

Once or twice, The entire file system refuse to work (No write possible),
but then every thing was OK, when MMC was formatted with PC.
You are right, I need to update library.

The MMC / SD / Compact Flash memories are all formatted, off-the-shelf,
as FAT16 not FAT32.
