That's unfortunate. Do you have an external programmer (something like
a buspirate) that can be used in case things go wrong? Can you tell if
there is anything written to the lower half of the chip? It could be
as simple as concatenating the 256KB image to itself to create a 512KB
image. But I wouldn't recommend trying that unless you have a good
means of recovering.
