Hi, 

I'm working with a STM32WL5MOC with the STM32Cube FW_WL V1.4.0. In my main.c I have this initialization:

 MX_GPIO_Init();
 MX_DMA_Init();
 MX_RTC_Init();
 MX_LPUART1_UART_Init();
 MX_USART1_UART_Init();
 MX_ADC_Init();
 MX_CRC_Init();
 MX_SPI1_Init();
 MX_LoRaWAN_Init();

 I put the MX_LoRaWAN_Init after all inizialization. However, I noticed that the code get stacked in MX_RTC_Init();, in particular on here if (HAL_RTCEx_SetSSRU_IT(&hrtc) != HAL_OK).

I attach the ioc file and the main.

Thanks.
