>> The address you mention is in ROM. Perhaps your value gets written to cache, and then evicted. Of course it is flash ROM, so you could overwrite it if you really wanted, but down that road lies void warranties and expensive paperweights.That's fine. Being able to overwrite ROM to modify originals meens I can always revert back by restoring it.
On the other hand, from what I understood, set_parameters_data uses ROM to store variables. So, if the hardware checks control sum, how it knows what pages to check? Are those pages somehow marked? If this done on software, where is such code?
Anyway, if community feels that my proposed "sacrifice" is useless, then I rest my case.
