... speaking of which, the main glitch in that RTC code (other than lack of features, like RTC alarm) is that the RTC reports 12-hour times with no way to examine its internal AM/PM indicator. Which means that the typical "load system wall clock from RTC on boot" scenario will produce system clocks that are wrong, about half the time, as will asking the RTC for the current time. It's maybe best not to use this RTC at all. I just thought I'd highlight that fact, in case anyone's in a position to update that MSP430 firmware to have reasonable RTC support. - Dave _______________________________________________ Davinci-linux-open-source mailing list [email protected] http://linux.davincidsp.com/mailman/listinfo/davinci-linux-open-source
