Does the Firefly RK3288 have no battery to power the Real-Time Clock (RTC) when the power is unplugged?
The schematic for the board shows a battery connected to VCC_RTC, but the actual board just has two unpopulated pads. If true, this means that the board loses track of time every time it is unplugged, which is consistent with my experience. The only solution would be to use a network connection, but a network connection is not always available.
you can solder wires and add a battery if you need

Indeed. I am actually using this board as a proxy for a few RK3288-based devices, so my larger concern is that the various devices seem to not have any RTC batteries either. Even if those devices did have VCC_RTC pads, I would have to open each one up and modify it.
Firefly RK3288 Reloaded has an RTC battery socket
This is so good, I’m liking it immediately. Hope I perform well in the CPGP new practice questions files exam – wish me luck!
