Hi,

I am trying to interface serial NOR flash with SAME70.

Now while trying to write to the flash IC, i mean whenever I do a  page write, contents in that page gets written in every page in that sector.

Page side is 256 bytes & sector size is 64kB

ie, if I clear any page in my sector, then the entire sector gets cleared and if I write "Hi" in any page at any position, then I can read "Hi" from that position from every page in that sector.

I really don't understand like what is happening.
Any clues on this issues?

What did I miss?

This topic has a solution.

Figured out the issue.

In one location i used '>' operator instead of '>>' operator while sending second nibble of memory address for almost every operation.

My bad.

sad

Anyway, thanks for the support.
