The RTC does not work properly in this scenario (interrupts are not occurring, clock resetting, MCU is being powered via the CR1025 battery).
See not_working.png
It works fine if I use two separate batteries like below:
see working.png
Is the design flawed? I want to run the RTC if any one of the batteries is present or use a supercapacitor instead of the CR1025 as a backup.
Thank you
Please series in resistor around 300OHM between battery and diode and try to test again.
Some wrong about open your pictures,could you please attached them again?
@guoweisun I uploaded the images again.
