I am flashing a hex file that has power management that enables the low power stop modes On version 2.17 everything works fine, but when I upgrade to version 2.20 it starts to freeze ~2mins and 11s after flashing. 

I have been flashing using the CLI.

I have tried multiple times on v2.20 and when I downgrade back to v2.17, it starts working again.

I know that it works on v2.15 as well.

Download the contents of the flash and compare them. The chip doesn't know what version of software was used to flash it. If the flash is the same, behavior should be the same.
