PS2: I found my mistake that is Window value and Reload value are NOT set correctly. So questions are deleted. Thank you.
Attachment is a project which I reworked WWDG_Example of STM32F072RB-Nucleo (STM32Cube_FW_F0_V1.8.0) with STM32CubeMX. I use SW4STM32 IDE.
After compile this project, board debugging (F8) is not possible. That is debugger stopped at HAL_Init().
Commenting only main.c WWDG_API (L93, L128) will work normally (F8 works).
Please teach me why, I cannot understand.
HAL_WWGD_Start () is missing in HAL Library.
Is it WWDG start automatically after HAL_WWDG_Init ()?
PS: These are the same troubles, even if I change WWDG_Example to IWDG_Example.
Thank you very much in advance.
