STM32L476G-Disco LSE Startup Problem

Hi everyone,

I want to use RTC module and LSE crystal which is default on board 32768KHz. I generate the code via STM32Cube because I couldn't find any example of RTC that used via LSE. After generated, the code doesn't pass the LSE ready check. I guess the reason for that issue isn't hardware because the code is running on discovery board. I have tried firmware 1.10 and 1.9 libraries for stm32l4 but the result is same. Where am I doing wrong?

Luckily you can use other sources of the clock for RTC...
