Lately I was working on developing a filesystem which would support
filesystems stored either in the internal FLASH memory, or an external
device via interface like I2C, SPI.
Each system is supported by a different set of I/O functions. The set of
functions for the internal FLASH is written but I haven't written yet the
functions for the SPI or I2C.
If you think you can write the support functions I could send you the
sources.
The filesystem actually is similar to the FAT fs. It can support upto 64K
or 16M images. Filename size is configurable. It has functions like:
fget, fread, fput, fwrite, fopen, fclose, fstat, ftell. You can also scan the
directory listing. It does not support sub-directories.
