My jetson orin nano with jetpack 6.0 L4T36.3. I connected battery and set time for RTC0 and RTC1. However on a power cycle RTC0, RTC1 reset their clocks to 1970. I have set the time several times via the CLI, however when the computer discharges fully the clocks reset. Addition I found having or not the battery affects to the power on of jetson. Maybe RTC-battery is supported for power management IC.
How did you connect a battery? Are all necessary components on your board as below showing?
Is it Orin nano dev kit? Your board looks not. What’s the part number of your board?
What are the result of dmesg |grep rtc and ls -al /dev/rtc?
You may need to check with the board vendor for your RTC battery connection and confirm how to implement RTC function correctly.
