Hi when trying to get some of the examples for the STM32WL devkit (Nucleo-WL55JC1) working for LL LPUART serial with the external 32kHz crystal, I've noticed that LL_RCC_LSE_EnablePropagation() is never called in SystemClock_Config. It looks like this is needed for LPUART to use the crystal as its clock?
I also can't seem to find an option in CubeMX to enable LSE as a system clock for LPUART
The examples I've tried from STM32Cube_FW_WL_V1.0.0:
Examples_LL -> LPUART -> LPUART_WakeUpFromStop_Init
Examples_LL -> USART -> USART_Communication_TxRx_DMA_Init
