They come installed in ubuntu and Raspbian and even Windows. Here is how to get the real deal: raspberrypi.stackexchange.com/questions/68811/…? | |

@Milliways The documentation I am using is /boot/overlays/README which is good but perhaps not rigorous. dtoverlay=i2c-rtc,<param>=<val> is perhaps ambiguous.

@joan if you'll edit your response to omit the =1, then I'll accept it as a solution.

OK, that worked fine. @Milliways @Joan the =1 is not required. Thank you guys.

dtoverlay=i2c-rtc,ds3231 should work (it is what I use), not sure about the "=1" which is not mentioned in documentation.

dtoverlay=i2c-rtc,ds3231 has already been added to /boot/config.txt, and hwclock works as expected.
