Is that actually a read from our flash - are those numbers believable? We put a scope on the chip select of the flash chip put couldn't trigger a signal, so we're in doubt.
I still can't erase or write the flash even though I tried your unlock commands. I am trying to figure out if those addresses work for the S29GL01GP - I don't think you mentioned your exact chip - could you please let me know your spansion model number?
Still trying to dig into the 12.2 spec section ;-) .
Thanks! Robert
