Brian has shared his resolution on customizing the GENERIC kernel here https://lists.freebsd.org/archives/freebsd-arm/2022-February/001024.html which allows to free-up the i2c address 0x68 which by default is being used by the MAX77620 RTC driver from the SOC_NVIDIA_TEGRA210. So, you need to add these lines in your kernel (I assume it's still the GENERIC otherwise use your existing config), include GENERIC ident GENERIC-PI nooptions SOC_NVIDIA_TEGRA210 and then recompile. Keep your /boot/msdos/config.txt and /boot/msdos/overlays/ds1307.dtbo files intact. After recompiling and rebooting, you can check the dmesg if the ds1307 driver is loaded, otherwise invoke "kldload ds1307" and see if it's detected. Add a line into your /boot/loader.conf with ds1307_enable="YES" if necessary. Lastly, kindly backup your data before recompiling for safety. This is the way I do it with my ds3231 driver, hope you will get the same result.

The clock stops and goes back to the time when you set it. This b= ehavior is observable when my RPi system is rebooted or shutdown.

I tried loading ds1307.ko in the loader but it has no effect on the result = - still shows up as a MAX77620 for me.

I haven't tested pulling the power yet as I'm remote from it.

Did you re-compile your kernel? Brian has shared = his resolution on customizing the GENERIC kernel here https://lists.freebsd.org/archives/freebsd-arm/2022-February/001024.= html which allows to free-up the i2c address 0x68 which by default is b= eing used by the=20 MAX77620 RTC driver from the SOC_NVIDIA_TEGRA210. So, you need to add these lines in you= r kernel (I assume it's still the GENERIC otherwise use your existing c= onfig),

include =C2=A0 =C2=A0 =C2=A0 =C2=A0 GENERIC
ident =C2=A0 =C2=A0 =C2=A0= =C2=A0 =C2=A0=C2=A0=C2=A0 GENERIC-PI
nooptions =C2=A0 =C2=A0 SOC_NVIDIA= _TEGRA210

and then recompile. Keep your /boot/msdos/config.txt and=20 /boot/msdos/overlays/ds1307.dtbo files intact. After recompiling and reboot= ing, you can check the dmesg if the ds1307 driver is loaded, otherwise invo= ke "kldload ds1307" and see if it's detected. Add a line into= your /boot/loader.conf with ds1307_enable=3D"YES" if necessary. = Lastly, kindly backup your data before recompiling for safety.

This is the wa= y I do it with my ds3231 driver, hope you will get the same result.
