Done ntp is already the newest version. This can cause stability problems. Fortunately the I2C bus lets us interoperate with 3.
As it syncs the time from a time server it writes that time to disk. When the BBB comes back up without an internet connection, running date at the command line should show you the incorrect date you set above.
How to Change Your BeagleBone’s Hostname and Password - Fortunately the I2C bus lets us interoperate with 3.
They might be helpful for other devices or other Linux flavors but some things are likely to be different. This device is available from a bunch of different sources but the design is exactly the same. The second problem is that the Tiny RTC is designed as a 5V device but the BBB is a 3. Fortunately the I2C bus lets us interoperate with 3. This can cause stability problems. If you plan to use the square wave output, remove R8 too. Connecting to the Beaglebone Refer to one of the many available on the web. This may be different on other devices, which would change many things below. Most of the following instructions came from with a few details filled in or tweaked for my specific environment. Add the RTC to the device tree To make the kernel aware of the RTC device and to have it enabled at boot, we need to add it to the device tree. Create a file named i2c2-rtc-ds1307. Now we need to tell the kernel to load that device overlay on boot. RTC0 is the built-in hardware clock in the BBB but it has no battery backup. RTC1 is the DS1307 that we connected to the BBB, so now we have two hardware clocks available. Make our RTC the default We can add a udev rule that will symlink to our battery-backed RTC instead. The systemd-timesyncd service is responsible for time syncing in this build of Debian. As it syncs the time from a time server it writes that time to disk. We need to set the system time from our RTC before systemd-timesyncd checks it, and we can do that by creating a new systemd service. When the BBB comes back up without an internet connection, running date at the command line should show you the incorrect date you set above. This tells us that the date was loaded from the DS1307 on boot, which is what we want. This tells us that the system clock was synced from the time server and the updated time was also copied to both hardware clocks, which is what we want. If you walk through these instructions and find errors or clarifications, leave a comment below.
