I am working with an inventek ISM43362_M3G. We have a board that keeps a supercap charged and attached to the VBAT line.
In 3.3.1, time was preserved through power cycling for a period of time (at least 20 minutes). I updated to 3.5.2 and enabled WICED_ENBALE_MCU_RTC.
I set the RTC with platform_rtc_set_time and read with platform_rtc_get_time in app, and it works fine, but on a momentary power cycle, it reset to 0 (Jan 2000).
Has something changed in 3.5.2 with the RTC, or am I missing something?

Ok, just found it.
had an extra call to platform_rtc_init() being called before the internal oscillator was being set up.
