Hello,

 

Hello, I have connected a pcf6523 RTC module to my OrangePI plus 2E and I can not get it to work.

 

 

The   i2cdetect -y 0  command gives me the following answer:

     0  1  2  3  4  5  6  7  8  9  a  b  c  d  e  f
00:          -- 04 -- -- -- -- -- -- -- -- -- -- --
10: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- --
20: 20 21 22 23 24 -- -- -- -- -- -- -- -- -- -- --
30: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- --
40: 40 41 42 -- -- -- -- -- -- -- -- -- -- -- -- --
50: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- --
60: -- -- -- -- -- -- -- -- 68 -- -- -- -- -- -- --
70: 70 -- -- -- -- -- -- --

 

The next thing I have to do is insert the sudo echo pcf8523 0x68 > /sys/class/i2c-adapter/i2c-0/new device command to activate /dev/rtc1 but this does not work.

 

 

I think the problem is that my system does not have the driver for the module because in the folder /lib/modules/4.19.17-sunxi/kernel/drivers/rtc I do not have the file rtc-pcf8523.ko y have rtc-pcf8563.ko

 

How can I add the correct driver for my rtc module?

 

Thanks for your help

By building yourself a new kernel ...

... or wait new build when with this driver will added ...

Thanks martinayotte,

 

I've never done anything like that. Any help on how to do it?
