Hello,

In order to implement RTC You may use scheme, based on i.MX6 reference design,

and follow Development Guide recommendations :

If VDD_SNVS_IN is directly supplied by a coin cell, a schottky diode is required between

VDD_HIGH_IN and VDD_SNVS_IN. The cathode is connected to VDD_SNVS_IN.

From the Datasheet, Table 9 (Stop Mode Current and Power Consumption), there is

SNVS Only mode, when VDD_SNVS_IN powered and all other supplies off, and SRTC

is running.
