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
