I had no VBAT. I guess I did not get enough solder on the ground pad for the battery. Re soldered the ground pad (without taking the bat holder off, tricky) but I have VBAT and the clock now holds through a power cycle.
Just finished building one of 2 controllers yesterday, bench tested all night no problems but the clock is not saved through power cycle/outage. Also if you do not use NTP or due to internet outage, where is the option to set the clock?
