Ah, OK. In that case I don't know why it didn't finish writing then, unless my temporary connections between RasPi and flash moved a little bit or just aren't tight enough for a good signal. Cable length maybe - signal path is RasPi -> 40pin IDE cable -> hookup wires (15cm) soldered to the pads on the chip. Now that I've got more female-female jumper wires I can go direct to the Pi to shorten the distance drastically.
That makes a huge difference for the quality of the signals :)
Just hooking up now.
Currently I've got the flash hooked up to a parallel port on an old desktop so I can use SPIPGMW which has just dumped the whole 16mb to disk so I can try writing it back to see if it fails indicating a bad area in flash.
That will be quite slow, but in any case please report back with a complete verbose log (-o write.txt creates one easily).
Interestingly SPIPGMW wrote back all 16mb without complaining but the board doesn't boot at all so once I've got the Pi writing again I'll let you know what happens.
