Armbian Buster and RTC DS3231

[mbo]

Hi!

 

Can someone point me to a tutorial/documentation on how to setup a DS3231 RTC module on Armbian Buster?

I'm currently using a Tinker Board S with Armbian 5.9.14. My RTC is correctly connected to my board. It is detected:

 

sudo i2cdetect -y 1
     0  1  2  3  4  5  6  7  8  9  a  b  c  d  e  f
00:          -- -- -- -- -- -- -- -- -- -- -- -- -- 
10: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- 
20: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- 
30: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- 
40: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- 
50: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- 
60: -- -- -- -- -- -- -- -- 68 -- -- -- -- -- -- -- 
70: -- -- -- -- -- -- -- -- 

 

I've followed these posts:

without success (no UU )

 

Thank you

Thanks but found out that "overlay are not supported on Rockchip"...
