Hello,
I'm aware of the wearing problem of FAT and I don't think it's very
suitable format at all nor for data logging - that is what I want to do.
But I also must assume that not everybody is running linux
and is capable of mounting a MMC card or access it bytewise.
The card is a cheap (in terms of uC hardware, and PC hardware
and needed software ->SPI, protocol)) way of transferring data, or?
Transferring via
RS232 - too slow
USB - uC hardware complicated.
IrDa - software protocol stack, etc... often cannot get this running
with out of the box windows and two laptops seems like nightmare.
wireless - huh... EMC, FCC ....
smthing else?
Just tried the romfs. There's a working windows driver out there
that could mount a romfs formated floppy.
Descriptions of the fs structure can be found here:
http://lxr.linux.no/source/Documentation/filesystems/romfs.txt
Good idea Garst!

do you write FAT filesystem or a custom format and is your code open
source?
At present there is no filesystem, it just writes 512 byte blocks, but
it skips the first one. If I need a fs, I I'll probably use romfs, found
on linux.
Hi,
I heard some rumours that M$ is going to change their attitude to the usage
of FAT. It seems they want to turn down everything/everyone that does not
pay for a licence in future.
I was loooking into the MMC part too, and therefore was looking for a
suitable
fs. It should be free and easier to write. But it should also be somehow
read/write-able by various OSes. Did really find anything yet.
Greetzs,
Georg
