RE: [ECOS] FAT/VFAT support on ECOS

[ramanabv]

Hi,
I had previously offered to provide our version of FAT16. I did provide it
but it was rejected since this doesn't conform to the ecos standards.
 However if any of you want to have it let me know. I will send this to you
in as is where is condition.
As of now it only has root directory support and FAT16 and works with
SANDISK CF with custom PCMCIA interface (not using ecos PCMCIA Driver)
regards
ramana

 Yes, here I am. I have written the FAT code for the NEC uC to acces FAT
 formatted MMCards. If you are interested, I can provide few documents that
 are quite good.

 Unfortunately I can't provide the sourcecode, since it has been created
 during my job time and will loose the job. If you are interested I am ready
 to be helpful as much as I can. For better discussions you can reach me via
 ICQ. I will send my number to your personal e-mail, when requested.

 regards,Igor

RE: [ECOS] FAT/VFAT support on ECOS

[Holtzclaw, Kris]

Paul,
I too was hoping to avoid re-inventing that wheel... to no avail... There doesn't seem to be any FAT code for ecos(that's available anyway)... I have looked into the possibility of porting Linux FAT code(a big job untangling as you mentioned) or even using the ECOS JFFS2, DEVFS or RAMFS code as templates to develop FAT code, but our project schedule won't allow the time for that at this point. We are running an X86 SBC with a Compact flash attached via an IDE port. I have ported the IDE drivers from redboot, so I can at least read/write sectors. Was hoping to find some ECOS FAT code that I could modify and install quickly, I've searched everywhere... So now at this point we are planning to use a "nuts and bolts" file storage/retrieval design that simply uses a data structure and sector read/writes.
Sure would like to find some basic FAT code too... If you happen to run across something usable, a heads up would be appreciated!
Regards and best of luck!
Kris H.

Hello:

   There have been various postings about support for MS FAT/VFAT file system
and ECOS -- one with source, as I recall.

   I'm working to put up a basic facility for accessing FAT16/VFAT formated
media.  The interface (ATA/Compact Flash) is built and working.  The need is
for the logic to handle FAT and clusters to create, write and read files.  Seems
like this wheel has got to have been re-invented many times. 

 I've looked at the Linux & FreeBSD code -- it is all tangled with inodes and
the unix end of file systems.

 Does anyone out there know of any "just the basics" VFAT code?

Thanks in advance,

Paul Davis

[ECOS] FAT/VFAT support on ECOS

[Paul Davis]

Hello:

   There have been various postings about support for MS FAT/VFAT file system
and ECOS -- one with source, as I recall.

   I'm working to put up a basic facility for accessing FAT16/VFAT formated
media.  The interface (ATA/Compact Flash) is built and working.  The need is
for the logic to handle FAT and clusters to create, write and read files.  Seems
like this wheel has got to have been re-invented many times. 

 I've looked at the Linux & FreeBSD code -- it is all tangled with inodes and
the unix end of file systems.

 Does anyone out there know of any "just the basics" VFAT code?

Thanks in advance,

Paul Davis
