Kindly support us for resolving the issue

Hello,

Not sure what do you mean by "During flashing the software, it is failed to configure LSE crystal with internal RTC enabled". ?

Do you mean that the RTC failed to be configured at your application startup? and what is the symptom? enable to write to a register or what?
