filesystem in eeprom

[А. Панфилов]

Hello. I've read some documentation on your website and i've discovered a possibility of creating filesystem on the eeprom device. Unfortunately, i couldn't find a good example of using this feauture. I've tried to write my own app similar to this example: http://wiki.rtems.org/wiki/index.php/Using_the_RTEMS_DOS_File_System#NV_Diskin which I want to use the highest half of my eeprom (which size is 1mb) as a storage with filesystem.But nothing works. Here's my code:http://pastebin.com/cVuikdt2
I've got unusual eeprom device, for which i've written special read/write functions (eeprom_read/write in my code). These functions are working fine, but when I try to use them in my code, they are never called. Probably, I'm doing something wrong and I would really appreciate if anyone could give me an advice or working example.
Thanks in advance.
