RTC and RAM backup on RCM4300

Hi all,

I am new to RCM4300. I have been working for few days trying to figure out why my RCM4300 does not backup RTC and RAM even battery is connected?

Any solutions, anyone?


Hello, There is a Connection for user-supplied backup battery
(to support RTC and data SRAM). If you are testing this on the Rabbit dev board, you should be able to run the RTC samples. Take a look at the RCM4300 Users manual, and the samples in the RTCLOCK folder in Dynamic C.
