STM32H7A3ZIT6 Custom Board Development

Hello,

I am currently trying to develop a custom target for the stm32H7A3ZIT6 mcu. I understand there exists a custom target for the NUCLEO-STM32H7A3ZI-Q board. I am not quite sure but it seems the mcu used on the NUCLEO is the same chip. I am having difficulty setting up the custom target for the H7A3ZIT6 mcu as I am unsure if I can just inherit the same MCU SUBFAMILY and MCU as the NUCLEO-STM32H7A3ZI-Q board. I am relatively new to Mbed and embedding programming in general, any help would be much appreciated. Thank you in advance!

Thank you for the help. I have already seen these links and it did not really answer my question.
