Problem with RTC initialization

Hi, I tried to run this project on 2 different boards On one with black reset button (I dont remember revision know) is running perfectly and even without ethernet, the clock starts counting. On the second one(this one http://img-europe.electrocomponents.com/largeimages/R7039238-01.jpg) clock just stays in 00:00:00. I am planning to investigate it during the weekend. Could it be something with RTC or do you have other idea?

Thank you. Michal

Make sure there is HT (3.3v) on the VBATTERY connection (pin 19), check sheet 2 of the diagram. You may also have to set the RTC for it to start.
