How to configure stm32u5 watchdog timer in a project that contains the custom bootloader and user application part?

[Mohamed Aymen HZAMI]

Hello @MTapu.1​ and welcome to the community,

For the watchdog timer configuration you can refer to both examples under the STM32U5 Firmware:

• STM32Cube_FW_U5_V1.2.0\Projects\NUCLEO-U575ZI-Q\Examples\IWDG
• STM32Cube_FW_U5_V1.2.0\Projects\NUCLEO-U575ZI-Q\Examples\WWDG

If you don't have the STM32U5 Firmware you can downloaded from here
