On our variant of the i.Mx51 BBG and on the EVK the date & time (RTC) is randomly reset back to 1-1-1970. Sometimes only the time is reset/changed - other times the time & date are reset. This is obviously a critical issue when interacting with the outside world. The EVK and our design uses the MC13892 PMIC.
I understand there may be irrecoverable PMIC RTC issues that result in RTC reset. If this is true or not, Please confirm. And provide any Work-arounds which may be employed.
PS I have seen some MX53 and WinCE tweaks - but so far none applicable to this platform.
