I’ve got a problem with my RTC on Q2686. In trial, the RTC works fine, but now the system is installed outdoor for further tests and now, the RTC stops sometime.
The stoptime is random.
My system is supplyed by Li-Ion akku and Solarzells, so it’s imposible to have peaks on supply voltage. The backup battery is installed (instead the akku is connected at all time).
I supose it’s because of the temperature of -5°C… but i have a Class B (-40°C to +85°C storage and operating -20°C to 60°C)
Does anybody have some experience?
It can’t be the software, it works at room temperature
