RTC running on current Armbian release??

[Scott Ksander]

I am unable to get any RTC installed on a C2 with current Armbian.  i2cdetect sees the device ID but no joy getting anything to talk to it.   Yes, I know these are very old but they were donated to a non-profit and I am trying to help set them up for a project.  Current Armbian runs great and perfect for our need.  I need an RTC.  I have tried both the Odroid PCF8563 (0x51 seen) and DS3231.  I have tried all the online blog posts, rebuilt the Device Tree, etc. but can't seem to get things to work.  Any pointers would be much appreciate.
