This is bad. Version 0.9.3 (-r1204) first tries to erase the whole chip,
and only if that succeeds, it writes the new contents. In your case, it
has erased 15*64k of the flash chip successfully, and choked on the last
64k, so your ROM chip is *mostly* *empty* now. Please get at least
revision 1224 (via svn or snapshots) which adds partial writes and
leaves unchanged parts of the ROM unchanged and write a backup of your
ROM (I hope you made one) with that version.

That's interesting. Our current info about xw9400 is that they tie the
"top block lock" pin of the flash chip to "locked" in hardware, so
erasing/rewriting the last 64k can never work on these systems, unless
you override this hardware lock by shorting the two solder points next
to "F2" to make the boot block writeable.
