On one of my boards that use the SPWF04 module I have started to see Win7: Configuration Failure:4 which from the manual indicates the RTC cannot be initialised.
For these errors my approach was to hold the device in reset, power cycle it then bring out of reset.
I'm seeing the "Wind2: Reset" indicating the board is now back, but immediate I then get the same Configuration Failure:4.
This will repeat for as long as I'm willing to leave it, then maybe after an hour it will start up correctly.
Does anyone have any pointers as to the reasons why the device RTC may be having problems?
