And make sure no exceptions occur. That means no page faults,
stack faults etc. Note that while you have interrupts off,
nothing else (including the OS timer) will run. Keeping in mind
that the operation can take several *seconds* to complete (the
erase, anyway) the system can be disabled for quite a long time.
To do this properly is a far more difficult task than what you
probably have in mind.
IIRC some flash memories (Intel's strata flash?) allows you to suspend
and then resume delete operations and this will allow you to re-enable
interrupts often. Obviously this will slow down the process and will
made also the task more complex.
You should consider also that an error during the upgrade operation
may leave the device in a "bricked" state unless you provide and
alternate OS image that can be booted or other upgrade mechanism.
