Hi

Im having difficulties enablling RTC in my revpi connect. I set up time using:

sudo timedatectl set-time "2019-09-11 19:50:00"

but still after this

Code: Select all

timedatectl

shows

Code: Select all

pi@RevPi11201:~ $ timedatectl
      Local time: Wed 2019-09-11 19:50:25 CST
  Universal time: Wed 2019-09-11 11:50:25 UTC
        RTC time: n/a
       Time zone: Asia/Shanghai (CST, +0800)
 Network time on: no
NTP synchronized: no
 RTC in local TZ: no

What could be the problem

Hi tmehtonen, there is no problem at all. The command "timedatectl" you are using is the right way to set the RTC. Maybe you expected the "NTP Synchronized: no" and "RTC in local TZ: no" to be "yes", right?
This is normal that the RTC is not synchronized via NTP. And the clock is always synchronized according to UTC so this explains the TZ output.

Hi,
I doubt whether the rtc chip has been successfully initiated.
To confirm this, could you pls send the output of "sudo vcdbg log msg" and "dmesg"
