Is the EON RTC supposed to show up as a device (/dev/rtc)?

I just got my EON and am in the process of setting it up. I want to make sure the RTC is working properly before installing OMV.

When I first booted the system after installing Raspberry Pi OS Lite (64-bit), I noticed that the date was WAY off. Something like 2050-04-11 02:33:25.

I fixed this by setting the date manually:
$ sudo date -s “25 May 2023 15:35:30”

I have also set my timezone so I now get this:
$ timedatectl status
Local time: Thu 2023-05-25 15:36:19 MST
Universal time: Thu 2023-05-25 22:36:19 UTC
RTC time: n/a
Time zone: US/Arizona (MST, -0700)
System clock synchronized: yes
NTP service: active
RTC in local TZ: no

I have installed a CR1225 battery. But I am worried that the battery backed RTC is not working.

I don’t see a device for the RTC in /dev and I don’t see any information about the RTC in /proc/driver. I also don’t see anything in the dmesg output about any rtc or any i2c devices getting probed.

Is there supposed to be a device node for the RTC? Am I missing something here?


The “official” way is to use the argon scripts to access and get/set the rtc.
But you can add
to your /boot/config.txt to use it as /dev/rtc as well. You can’t use the rtcconfig script from argon then (schedules as well) and should not run argoneond.
