[avr-gcc-list] EEPROM handler/manager

[Torsten Mohr]

Hi,

i hope this is not too off-topic, but i'm searching
for smoe kind of software that manages the EEPROM
in a way that:

- whenever voltage goes down (not controlled by software)
  no inconsistent state of the data in the EEPROM can
  occurr

- some kind of checksum insures that the data in the
  EEPROM are consistent.  It would be fine if this
  checksum could also correct simple bit/byte errors.

- i can make some kind of "transactions" or "atomic"
  changes, when the EEPROM is in a certain state and
  i change some of its values and the voltage goes down,
  i want to have EITHER the old state OR the new state,
  NO inconsistent inbetween state.

This is some kind of standard problem that the writers
of filesystem code also need to take care of, so i assume
there could be several solutions to this problem available.



Has anybody got some hints for me?


Best regards,
Torsten.
