LPTimer counts only to 1 if running on LSE

[Felix_livetec]

Hi,

I'm using on a STM32L4R9 a LPTimer1 in interrupt mode. If i use it with the PCLK1, HSI or LSI as clocksource it works as expected. It counts to the ARR value and then the interrupt occours. If i use the LSE as clocksource the LPTimer seems only to count to 1 and the interrupt happens way to often (propably also at 1).

The LSE is also used for the RTC, which works fine.

Of course not. I completely overlooked it. Probably because I didn't expect that the compiler wouldn't have an error here.

Thank you

Felix
