It almost seems like there is a cache issue. If the processor isn't
actually writing the info the FLASH, but actually has it in the data
cache, then a read back of the addresses in question would show no
difference as it was reading from cache, not from the actual address in
FLASH.
Of course it has been years since I looked at how the FLASH drivers are
actually writing to FLASH and how redboot is reading from it, so the
cache may actually be disabled during these operations.
