I’ve installed the RTC battery and run the configuration script to set the time on the RTC. I don’t think it’s working correctly as I’ve run the following checks…
Running sudo hwclock -r --verbose
I get the following output…
hwclock from util-linux 2.36.1
System Time: 1660171681.701987
Trying to open: /dev/rtc0
Trying to open: /dev/rtc
Trying to open: /dev/misc/rtc
No usable clock interface found.
hwclock: Cannot access the Hardware Clock via any known method.
Running timedatectl
, I get the following output…
Local time: Wed 2022-08-10 18:49:44 EDT
Universal time: Wed 2022-08-10 22:49:44 UTC
RTC time: n/a
Time zone: America/New_York (EDT, -0400)
System clock synchronized: yes
NTP service: active
RTC in local TZ: no
Note that RTC time shows “n/a” for a status.
I’ve found various steps on numerous sites that say to disable the fake-hwclock
, adding a line to /boot/config.txt
to enable to RTC’s hardware, editing /lib/udev/hwclock-set
to comment out various lines, etc. I also found a few postings here with steps to follow but after doing all of these things, I still end up with the two statuses above.
Does anyone know the definitive steps to both set up and verify that the EON’s RTC is correctly configured and actually working? I’d really appreciate some guidance with this.
Thanks.
