Здравствуйте! :)

Thank you for your report.
The reason why you see the "EN25B64" and "EN25B64T" variants be detect
is that they have the same RDID as the EN25P64, which is not uncommon.
However if I interpret your email correctly, then you have written your
EN25P64 successfully and without warnings or error messages by using
the flash chip definition of EN25B64. This is confusing for me because
it should actually not work. The EN25P64 and EN25B64 have very
different block layouts. The P variant has a unified sector size of
64kB while the B variants have "Two 4-Kbyte, one 8-Kbyte, one 16-Kbyte,
one 32-Kbyte, and one hundred twenty-seven 64-Kbyte sectors".

Did I miss something?
