compilation error for the processor STM32H7

[gauix4]

Hello I'm having trouble compiling for a processor STM32H7
if anyone has a little idea it would be great thanks in advance :)

Hi, seems you not use the correct arm gcc. The one you used seems old and does not support cortex m7.
What is your environnement?
How do you install the core?

[fpistm]

Any update? Else I will close this as this is only issue with arm gcc used by end user.

thanks for your answer sorry i did not have time to start bending over it so i just try again now and i have a new problem
the Arduino IDE environment

Hi @gauix4
It seems you have an environment installation issue.
Don't know exactly which one but not linked to the core itself but how you deal with core installation in Arduino IDE.
the stm32l4xx_hal_conf.h is in the variant selected. Here the NUCLEO_L412KB.
So, I guess your environnnment is not proper.
Start from a fresh install and use the board manager.
