I use an STM32F407 microcontroller for my project that i use RTC on it. The RTC is clocked from LSE. It works normally when the power is on. But when i switch off and on the device, the RTC falls behind the time. To make it clear i switched off and on the device 10 times and the time was nearly 8 seconds back from the time that i first configured. How can i fix this problem?
