DS3231 not save time

[thaksa]

I have enabled i2c and checked with i2cdetect and it is showing 68 . 

Try with Cracnkshaft, DS3231 is working properly.

Try with sudo hwclock -r show as below:
hwclock: Cannot access the Hardware Clock via any known method. 
hwclock: Use the --debug option to see the details of our search for an access method.

Did you try to use bwsrtc command in order to configure your RTC?

I had the same problem and I must have done 20 hours of work to fix it, changing GPIOs, changing rtc modules, reinstalling, re-flashing, updates, etc; check your module's battery! Replace it even if it looks like it works/has correct voltage.
