Time stops ticking when power is lost #39

Closed bkacjios closed 4 years ago

bkacjios commented 4 years ago

I recently bought one of these kits and flashed it with this custom firmware. One thing I noticed is that even with a battery installed, when I stop supplying power, the clock will resume at the exact time it was unplugged. The battery is brand new showing 3.3v, and I know it's working since the ram is keeping when unplugged for a long amount of time. Is this just a normal issue with my version?

Here's the schematics if that helps.

Welp.. I reseated the battery, since it seemed a little loose, and that completely fixed the problem..
