For the version sold in China, we will install CR1220 button cell (RTC backup power supply) by default when shipping. In this way, the system can be guaranteed to have an uninterrupted and reliable clock, which is not affected by factors such as equipment power down. The default shipping system image will integrate the RTC automatic synchronization service we wrote, so guests can automatically synchronize the clock without setting it, and can use RTC without feeling. The general principle is: When the system is turned on, the service automatically reads the saved time from RTC and synchronizes it to the system time.

If there is an Internet connection, the system will automatically synchronize the time from the NTP server and update the local system time with Internet time. When the system is shut down, the service automatically writes the system time into RTC and updates the RTC time. Because of the installation of button cell, although CM4 Sensing is powered off, RTC is still working and timing. In this way, we can ensure that our time is accurate and reliable. WARNING If it is the first time to boot, because there is no effective time in RTC, synchronization may fail, so just restart it directly. When rebooting, the system time will be written into RTC for normal use. 4.5 RTC • • • • Device 56:6A:59:B0:1C:D1 Lefun Device 34:12:F9:91:FF:68 test pair 34:12:F9:91:FF:68 Attempting to pair with 34:12:F9:91:FF:68 [CHG] Device 34:12:F9:91:FF:68 ServicesResolved: yes [CHG] Device 34:12:F9:91:FF:68 Paired: yes Pairing successful trust 34:12:F9:91:FF:68 [CHG] Device 34:12:F9:91:FF:68 Trusted: yes Changing 34:12:F9:91:FF:68 trust succeeded sh sh ED-IPC2000 Email: sales@edatec.cn / support@edatec.cn Web: www.edatec.cn | Phone: +86-15921483028(China) | +86-18217351262(Overseas) If you don’t want to use this service, you can turn it off manually: Re-enable this service： Read RTC manually： Manually synchronize RTC time to the system: Write the system time into RTC Trouble Shooting Please first check whether there is an rtc device (/dev/rtc0) mount: if not, maybe you used the official standard system, but didn’t install our BSP package.
