STM32U535 HAL UART Wake-up register callback missing
I'm unsure whether this is a software issue or wake-up callback is by default not present for UART on STM32U535 microcontroller. The rest of callbacks seems to be in place.

Hi
On STM32U5xx serie, there's no WakeupCallback (no WUF/WUS settings). So UART_HandleTypeDef type definition is correct.
On the other hand, the value HAL_UART_WAKEUP_CB_ID could then be removed from HAL_UART_CallbackIDTypeDef enumeration, for clarity's sake.
ST will raise a internal ticket to get this solved.
Thanks for pointing this.
Regards
