Compute Module 4 Real Time Clock

Making Your Raspberry Pi Use the Real Time Clock You will need to add the RTC kernel module to the file etcmodules so it is loaded when the Raspberry Pi boots. In a terminal window run sudo nano etcmodules and add rtc-ds1307 at the end of the file

I've been experimenting with the early release of Hirsute Gorilla and it works with the CM4 real time clock. So my conclusion is that the 20.10 kernelmodules do not fully support the Compute Module 4 and that this feature appears to be working in 21.04.

The Raspberry Pi Compute Module 4 CM4 has taken the maker and developer community by storm with its versatility, compact form factor, and powerful performance. While the CM4 is widely used for everything from industrial automation to IoT projects, one of its often-overlooked but essential capabilities is clock synchronisation.

I'm trying to use the CM4 IO board's Real-Time Clock RTC to persist datetime changes from within a docker container, so whenever the device reboots, it remembers the newly set datetime. By defau

In this Raspberry Pi RTC tutorial, we will show you how to add the PCF8523, DSL1307 or DS3231 real time clock modules to the Raspberry Pi.

Today, we will discuss the Interfacing of RTC module with Raspberry Pi 4 to provide real-time Control, we will create both a real-time clock and a stopwatch.

Includes real-time clock with battery socket and ability to wake Compute Module 4 Compact size of 124.5 x 108.8 mm Ages 14 The Raspberry Pi Compute Module 4 IO Board for CM4 w PoE Feature Type B is an ideal choice for evaluating the Raspberry Pi CM4 or for integration into final products.

Hello, I got my CM4 module up and running and would like to use the RTC functionality of the CM4 IO board. 1gt I assume it is not enabled detected by default on the RPi OS? 2gt Have updated the config.txt dtparami2c_vcon added The RTC then will be on i2c-10 address 0x51 7bit address Verified that RTC is on the i2c bus via sudo i2cdetect -y 10 My question is how the RTC time is set, how it

However, your Pi isn't going to have an internet connection and you want to maitain accurate time keeping--especially if it's not on all the time--then you need to add an RTC module.
