It looks like you have a custom board definition, and you have not configured it correctly. Please share your board configuration files to make progress here with debugging.

You can't use this object representation with double precision float (which the H750 has).

I suggest just removing this line and using the default object representation A. (You'll also need to remove the 4 lines after it as well.)

Hello, after deletion, it does work properly. But I would like to ask this object representation with double precision float (which the H750 has).What does it mean, and how can I avoid similar problems the next time I want to continue compiling the firmware. Will there be a description of the questions in the data sheet of the chip?

Hello klora-sun, would you mind, if i ask you for your port for stm32h750 board?

The problem looks to have been resolved, will close this issue.
Information about the MicroPython object model can be found in https://docs.micropython.org/en/latest/develop/memorymgt.html#the-object-model and in py/mpconfig.h in the codebase.
