Well after playing a bunch of option bingo I got here:

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
