Thank you very much for this information. I had to guess the device IDs
because they are not mentioned in the datasheet.
The AT25F1024A has 0x60, the AT25F512A has 0x65, the AT25F025B has
0x6500... but apparently assuming at least some sanity has failed to
reflect the truth.

So, according to your verbose log your AT25F512 has the same ID as the
AT25F1024A (according to its datasheet). *sigh*
Before I'll make some changes to the code I'll try to find someone with
a AT25F1024 chip to test.
Kind regards/Mit freundlichen Grüßen, Stefan Tauner
