Jasem,

I installed the ds3231 module on my RPI3 (running Ubunto MATE). I read how you had to modify some of the boot and config files to let the RPI3 know its there, but the system still doesn't read the hardware clock from the ds3231 when it boots. e.g., when I first got things going, it was on July 1st, but when I came back a few days later on July 3rd, and typed the date command, it still had July 1st. It I typed hdwclk -r, it read the correct date and time on July 3rd. Somehow, the date and time is still not getting loaded into the system during bootup. I can fix the problem pretty quickly by just typing the "hdwclk -s" command and then the system time & date agrees with the ds3231 time & date. I may have missed a step when installing the clock.
