How does the erase fail?

What map configuration is selected? Where are the hybrid blocks, at the bottom
or at the top of the address space?

Does the erase fail even when address is aligned with 64k and the size multiple
of 64k? Does the following fail?

$ mtd_debug erase /dev/your_mtd 0 65536

The non-uniform erase will fail if it can't select a sequence of commands that
can erase the entire requested chunk.

Cheers,
