IMX6Q svns RTC loosing time across power cycles.

Hello,

 

I'm using a variscite DART-MX6 (i.MX6Q).  I'm trying to test the svns rtc.  I can set and read back time, but with a power cycle it looses its settings.

 

Currently my system is open (SEC_CONFIG = 0). 

cat /sys/fsl_otp/HW_OCOTP_CFG5
0x0

 

Assuming power is properly applied, does the system need to be closed (SEC_CONFIG[1]=1) in order for RTC to keep time across power cycle?

 

Thank you,

 

Marco
