Yeah, we can do that.  I need to amend the patch a bit to prevent the protected range lock from being lifted unintentionally and will add some debug statements if/when any write/erase cycles fail.

write/erase cycle is unsuccessfully tried, is it? This way, it would also

make chasing the root cause easier.
