Which board part no to select for nucleo-h755zi-q

[Sanjeev-Hegde]

Hi,
I have nucleo board Nucleo-h755zi-q.
If I select Nucleo-144, i don't see the specific board whereas if I select generic stm32h755xx, i don't see specific board part.
If I use the default board part selected STM32H743XI and upload the code, interrupts are not working. I don't see exact alternative boards from usermanual that i can use like NUCLEOH745ZI-Q and NUCLEO-H7A3ZI-Q. Should I use STM32H745XI or STM32H7A3ZITxQ instead?

I am new to stm32, please help me on this

Hi @Sanjeev-Hegde
This simply means the board was never added.
It have to be added to be able to use this board.
