Hi Gary,
I will do this in a day or 2 . Nice if you can incorporate this for others
to use.

This would be very interesting. If you wouldn't mind sending it to me,
I'll give it a look and see what it will take to get it into the main
sources.
(In case you aren't aware, I am one of the main developers of eCos and
have such access to the repository)

I know that several of my customers would be interested.
They'd like to use CF devices for logging data to be analyzed
on a Windows or Unix host system. FAT16 would work just fine
for that.

Hi,
It would be very useful if could make it available at least as a third party
project.
We thank you in advance for you kindness.

Hi,
I can post you the code (Fat16) we have developed and are using. While I can
say it is working fine, I can't guarantee that it will work straight out for
you and you may need to adapt it. It does have short comings - there is no
caching etc.
There is no support for Fat 12 ( I think) and Other Fats.
We are using this with PCMCIA compact Flash with ATA command set (Sandisk).
So let me know if any one is interested.

A MultiMediaCard (digital cameras and MP3 players often uses MMC cards)
is similar to SmartMedia but have a serial interface witch make it
a good solution for high capacity storage device for small uC based systems.
The 3
wire interface can be used in two manners: SPI communication or MMC protocol
communication.
The first one reaches 1 Mb/S the seccond one 20 Mb/S but requires a
dedicated interfacing
component witch at the moment isn't available, so you have to implement it
on a FPGA or
emulating it by SW. The next generation of MultiMediaCards are called SD
Cards.

Hi all,
I am new to eCos,
I've to add a MultiMediaCard Driver to eCos. The driver works fine but,
to make the MMC readable for "standard" MMC readers,
a FAT12/16 file-system should be used.
Is there someone who has wrote a FAT16 support for eCos? If yes, it
would be possible to receive the necessary source code ?
Best regards, Joel Brenner
