Yes. There is another flash between the two. The chip is bootblock-protected unless PIN30 is pulled up to 12V. I forgot that and flashrom failed to complete flashing. I flashed again with that PIN wired to 12V and send you the log of the successful flash. So I guess flashrom only flashed bootblock this time.
