Why?

A power-on reset is "harder" than NVIC_SystemReset()...

But you don't want to use that? Why?

Tie a open drain GPIO pin to NRST and set it low to hard reset the chip.

Perhaps stash a magic value in RAM at the 5 minutes reset, and flag to yourself not to do that again when you recognize that at start up.
