→Q: How to enter RTC mode?
=== Q: How to enter RTC mode? ===
By default, iMX6 RTC driver is built into the Linux kernel. Upon power-up, it prints informational messages that look like this.
<pre>
[ 2.017007] snvs_rtc 20cc034.snvs-rtc-lp: rtc core: registered 20cc034.snvs-rtc-lp as rtc0
[ 234.876402] System halted.
</pre>
If a coin call battery is connected to PMIC_LICELL, RTC will be kept alive even if 3V3VIN voltage is removed. Please refer to [[Integration_guide_(Axel)#Real-time_clock_.28RTC.29|these important issues]] related to RTC power handling.
