It showed as 1st of Jan 2000 and the time was counting up from 0 seconds. I then remarked out the dtoverlay entry, rebooted, and ran get time py file. dev/rtc0 to read time failed: invalid argument. Running hwclock -r now gets me that same error message I got the first time around. I left it unpowered for a couple of hours and booted it up to check it again. I did the dtoverlay=i2c-rtc,rv3028,backup-switchover-mode=1 config.txt edit and rebooted. I’m pretty well back to where I was after the two steps back.

And to sort out how to actually set it up as a RTC in Raspbian.
If it also works that means all I need is a battery. If that breakout checks out OK I’ll swap the battery over to the other one, set the time in it, and leave it sit unpowered overnight. I’m going to try and leave it idle with no power for at least 12 hours. My next step is to leave the Pi unplugged tonight and check it tomorrow some time. Then swap the battery over to the other one and wash rinse and repeat.ĮDIT: So far so good, both RV3028’s are keeping thier time. I’ll reinstall the Pimoroni software, and check it again to see if it has kept time. It will have been siting for 30+ minutes with no power. There is a note to that effect in the set time and get time files.

Looking at the python code it only uses the battery if Vin drops below 2V. I’m going to check it one more time after I’m done reflashing my SD card. They both work and the one thats plugged in right now is keeping its time.
That gets control back to me and lets me run the Pimoroni set time get time python files. I remarked out the rtc dtoverly entry in config.txt and rebooted. If it works its likey a hardware issue with the other one. I’m going to leave the second RV3028 in and power down, then check it in a few hours.
This Pi is not connected to the internet. I had checked this second one yesterday and its been sitting unplugged since then. Bad battery maybe? I powered down and swapped in my other RV3028 and it read the correct time. It showed yesterdays time and hwclock -r gets me that error message above. But after leaving it unpowered overnight its not working anymore. After about a 15 minute shutdown with no power to the Pi it was Ok. I reset it to the correct time, and tested it once. dev/rtc0 to read time failed: invalid argument And running sudo hwclock -r gets me that error message. I booted up that Pi yesterday and the time was off. It now craps out if left for any amount of time. On boot up the displayed time is the time it was shut down at, but get-time.py shows the correct time is stored in the RV3028? Raspbian isn’t getting the correct time from the RTC though.Īs a test I let Raspbian sync its time online, ran set-time.py and verified it with get-time.py.ĭisconnected from the Internet and shut down.

I ran sudo pip install rv3028 and sudo pip3 install rv3028.
