On our application the pyboard is powered by a 3,6V Battery/Power supply connected through a hardware switch which shuts down the power completely.
In rare cases the RTC is not running after power on and start up sequence. If I plug in the USB cable and connect by VCP time.time() is just returning 0. It seems like the only solution to get out of this state this is to unplug and plug in all power cables again.
We would like to solve this issue.
Has anybody
- similar experiences?
- any idea to fix this?
- any idea for further testing to delimit the problem?
