I have a DS3231 real-time clock connected to my Beagelbone Black. I have these lines in /etc/rc.local to initialize the system time from the RTC:
echo ds1307 0x68 > /sys/class/i2c-adapter/i2c-1/new_device sleep 5 /sbin/hwclock -s -f /dev/rtc1 /sbin/hwclock -w It almost always works correctly however: Infrequently at boot up the hwclock commands fail and then the rest of rc.local doesn't run. Here's the error output I captured from rc.local: hwclock: Timed out waiting for time change. hwclock: The Hardware Clock does not contain a valid time, so we cannot set the System Time from it. Unable to set system clock. Any idea on what could cause this error?
