Did you test erase separately?
If write/erase is only working on the top 64 kByte, we probably have to
unlock the rest of the chip as well. Since our Pm49FL004 code already
has unlocking routines, we probably need a board enable for you.
Do you have a multimeter or continuity tester?

We can try.

The P49FL004 should be supported just fine. CK804 is OK as well.
Definitely a board enable issue.
