Because DUE's reset connects NRSTB pin, pressing reset will reset the chip including the Backup region (RTC, RTT and Supply Controller), that means RTC's time will be set 2007.1.1 and etc. But in SAM3x, there is another NRST Pin, if reset connect this pin, it will not reset the Backup region (RTC, RTTand Supply Controller), thus, I suggest arduino due make some changes to avoid the RTC's reset.
Your right about the reset, but I doubt that will ever be changed. If you can wait 6 months my board allows both types of reset ______Rob
What if i turn off taiji-uino by powering off and turn on again? Will doing this cause rtc reset?
