That is because the test for 512k+ was the wrong way around in the read
Non-mapped memory also reads as ff (same as erased) using mmap method.
The erase also needed the Block Protection to be disabled, on power-up
the Block protection defaults to on (but, maybe not with the chips on
your board.. What type?).
See my re-worked and re-re-worked patches.
