I’m on the openmv M7. I like to keep the RTC of the stm32m7xx battery powered to retain the time if the openmv is in stop mode.
Acccording to the schematics VDD and VBAT are connected.
That means I will draw my battery if no other power supply is given.
That means I cannot power the battery domain in openmv m7 sepeately to keep RTC information while the openMV has no access to main power supply.
Is this correct?
