Hi, I'm using the M52210DEMO board and the RTC in the processor runs fine, but when the board hasn't been powered in a long time and then is powered the RTC clock just doesnt work. Values can't even be written to the registers. The only thing I can think of is that it has to wait for the Supercap to charge. Because after active for I donno 10 mins the clock begins to run again.
Anyone know how to prevent this?
