Enabling over-drive on F7

I am having trouble enabling regulator over-drive on a Nucleo-F767ZI.


I have now simplified my code down to just trying to enable OD right away after power up, which should be possible since system clock source is HSI by default, and no peripheral clocks are enabled?


After setting the ODEN bit in PWR_CR1 to 1, I still read back zero. Also, the ODRDY bit in PWR_CSR1 never gets set.


Am I missing something?
