I am using bluepill. I can see 32khz signal on 32khz xtal using oscilloscope when power is turned off, however this xtal is turned off when mcu is booted.
My problem is my hse is not accurate and my clock is drifting when I applied power to circuit, it is stable when powered off. So, I wanted to use LSE allways. I read the library but couldn't find a setting for this, instead it looks like it is setting LSE so there should be a bug or something around there.
