Hi,
My customer is evaluating AM3354 RTC and checked the accuracy of the calendar.
He found +15min differences in 6 hours. (6 hours in real time vs 6 hours 15min in RTC)
This is more than 4% error and I think it is too much.
The RTC clock is RTC32KCLK(32k_aux_clk) from Peripheral PLL.
The RTC is running in Functional mode.
What are potential causes of such big errors?
Thanks and regards,
Koichiro Tashiro
