Pinout and software compatibility

Hi, STM32H725ZGT6 and STM32H743ZIT6 are pinout compatible? Can i use the same code for both?

If you are using a subset of the features of both, then yes. But these chips have different capabilities and flash sizes. Perhaps look into more specifically what your code does and uses to determine compatibility. In particular, look at program size and clock settings.

The peripherals and pin muxing can be different, subtle at times. See OSPI, SPIM

I'd be cautious using the same code. Diff the startup file.

CubeMX should give you a good idea how similar the pin out is.

You can determine which IC and stepping you're running from, and perhaps adjust, or manage a hybrid image.
