Pstorage for writing in eeprom or sd card

[krt]

how should i replace pstorage from sdk so as to write data to eeprom or sd card instead of flash(as defined in SDK).

I don't quite understand what you want to do. Do you want to modify Pstorage to use external eeprom or SD card? Or do you really mean replace? What kind of interface do you have to the eeprom or SD card? I think you should edit your question and try to elaborate quite a lot.
