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…
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.
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.
