I’m using aTC299 and in my software I have functions to read and write inside Data Flash. In one of my boards I can’t read anymore a Data Flash location because bus error, the reason is that this location does not pass ECC check due an unrecoverable error. Even if I erase the sector I still have the same issue, so it seems a permanent damage.
My question is how is it possible to damage a Flash location? Just writing too may time or is it possible to damage it in other way, just for example a power down during a writing operation?
