Hi all. I'm using the sector 7 of flash to storage some data. This data is update rarely by the user, not by an event.

The problem is that some devices is losing this data and in other cases, this data is changed. But the firmware funtion that do this is called only with the interface programming, so in normal use it should not occur.

Is there any other way to erase or change this data? I thought about EMI or something like that, but it should change all the flash not only this sector.
