Re: Re: NOOB needs help with RTC service

[iDoug]

Here is my addition to the /etc/rc.local file:

#	Get date-time from Internet (Write to BeagleBone Black BBB).

ntpdate -b -s -u pool.ntp.org

#	Write date-time to the RTC on OpenSprinkler OSBo.

sudo hwclock -w



#	Write the date-time from the OSBo to BBB.

#	(Just in case the Internet is not available and the battery

#	is working.)

echo ds1307 0x68 > /sys/class/i2c-adapter/i2c-1/new_device

sudo hwclock -s



exit 0

Please, let me know if you see any potential issues. This does seem to work, even on a OSBo that does not have the date-time initially.
