RTC Battery on RockPi 4C+

#1

Hello,

I just wanted to be sure about the following: does RockPi 4C+ has any kind of RTC battery soldered in?
I’m asking that because it seems that it doesn’t have a RTC connector slot.

Thanks.

#2

No. ROCK 4C+ doesn’t have RTC on board.

#3

I think I’ll go with 4B+ then.

Thanks Jack.

@jack is is really true? The wiki said, V1.2 and V1.41 has a rk809 chip, which has a RTC. My kernel found a rk808 and it seems to work. (V1.2 HW)

[ 0.985481] rk808-rtc rk808-rtc.3.auto: registered as rtc0

However, as it has no battery connector, its use is limited.
