I am currently using the PCF8523 for the Raspberry Pi in my Raspberry Pi 3B+ with the lastest Raspbian Stretch Lite (October 2018). I used this guide to set up: https://learn.adafruit.com/adding-a-rea ... d-test-i2c. Everything worked perfectly fine. After a random amount of time i cannot read the time from the RTC anymore. This error appeared when i type in
Code: Select all
hwlock -r
ioctl(RTC_RD_TIME) to /dev/rtc to read the time failed
