Default system clock on NUCLEO-F767ZI

GGran.2 · ‎2024-09-27

Good morning,

in the user manual "STM32 Nucleo-144 boards" is written that the HSE clock is linked to a 8 MHz oscillator. But when I enable the HSE clock in the .ioc file, the value is 25 MHz. I don't understand if the HSE clock is 8 MHz or 25 MHz.

Thank you

Yes, but now I generated from a board on CubeIDE 1.15.1 and the result is the same:

Sorry I didn't reproduce the behavior:

File -> New -> STM32 Project -> Board selector -> Find and select NUCLEO-F767ZI -> Next -> Name a project -> Unselect Use default Location -> Select location -> Finish -> "Initialize all periph ... Mode?" -> Yes

These are the steps you need to follow.

This is the view I'm getting with these steps:

I reproduced the behavior and getting the same screenshot as you got.

Seems you selected to Start from the MCU part number and not from the board and this is normal behavior.

The default clock source is HSI.

Hope I answered your question.

You are right! I didn't select the board, but I selected the MCU! Thank you very much for your patience. I didn't understand why my program runs with a wrong value of the clock, but it doesn't matter.

Thanks
