Issue with STM32Cube generating HAL_RTCEx_SetWakeUpTimer_IT in MX_RTC_Init. Configuration issue or bug?

[Chasqui]

Dear ST community, I am new developing firmware for stm32s. I am trying to enable the interrupt for RTC wakeup for a nucleoL476RG board using STM32CubeIDE 1.7.0 (which is using STM32CubeMX 6.3.0-RC5). I am selecting WakeUp: Internal WakeUp. I am also enabling RTC wake-up interrupt through EXTI line 20 and selecting Generate IRQ handler and Call HAL handler.

However, the  HAL_RTCEx_SetWakeUpTimer_IT call is not been created in MX_RTC_Init. Interestingly,  the alternate HAL_RTCEx_SetWakeUpTimer does get generated if I select Internal WakeUp but without enabling the interrupt.

Am I missing something in my configuration or is there a bug in STM32Cube? Help would be appreciated!

Hello @Chasqui​ and welcome to the Community :)

Thanks to have reported this issue.

You are right the MX_RTC_Init () is missing HAL_RTCEx_SetWakeUpTimer_IT () with STM32CubeMX version 6.3.0.

Our team are working to resolve this issue in the coming releases of STM32CubeMX.

(Internal Ticket 111366: this is an internal tracking number and is not accessible or usable by customers)

Meanwhile, you can use the STM32CubeMX version 6.2.1 as the HAL_RTCEx_SetWakeUpTimer_IT () is correctly generated in MX_RTC_Init () with this previous release.

Thank you for your contribution and your patience while we work to fix this issue.
