After going through the TRM and the TWL4030 datasheet, I
understand that the TPS69590/TWL4030 used with the Overo Earth has a
real-time clock subsystem.
I've seen a TWL4030 32Khz RTC clock option in the linux kernel. When
you use the Overo Earth + Palo43 combination, is the RTC function
active and enabled to regulate time.
Is there a separate pin for a small battery just to keep supplying
power to the RTC module, to preserve the system time between reboots.
