Yeah, it would be great to collaborate on that. I was out for the last
two days but now I'll start working on that. Do you have the code you
were talking about?
Question: Should the code be put in libfs/src/dosfs OR as a little
librarie that you link with RTEMS?
Have a nice day.

I was on vacation until today, so am joining you all a bit late.
I have code and some resources for a FAT12/FAT16 format but it is not
under RTEMS. I also plan to port this code into RTEMS for my project in
approximately the same time frame as Thomas.
Shall we collaborate? I also have a MIPS-based CSB350 which can be used
to carry out tests.
To start with, here are some references:
My code is based on Philip Erdelsky's "Reentrant DOS Compatible File
System v2.0": http://alumnus.caltech.edu/~pje/rdcf2.txt
I have extended it in the following ways:
+ Extended FAT16 support to 2GB
+ Implemented dynamic BPB parameter generation based on Microsoft's
+ specifications. Implemented bad sector detection and mapping (useful
+ for NAND flash).
Let me know if you are interested in code snippets from my project (It
wont use RTEMS function calls, but RDCF2 function calls, etc.).
Also, what RTEMS distribution are you all working off of? (Probably the
CVS tree-right? I have been working with the official 4.6.1 patched
with the CSB350 BSP from Jay.
