CubeIDE Issue - H755 LDO/SMPS settings missing

Hello,

I have found a strong isssue in:

STM32CubeIDE

Version: 1.15.1
Build: 21094_20240412_1041 (UTC)

(C) 2024 STMicroelectronics ALL RIGHTS RESERVED

The IOC configurator for the STM32H755 lacks an option in the RCC configuration

Power Parameters -> SupplySource

The PWR_DIRECT_SMPS_SUPPLY setting is missing.

This setting is required for the NUCLEO-H755ZI-Q board which default supply configuration:
the SMPS feeds the core without using the LDO.

Regards.

Hello,
thank you for this pertinent remark.
But there's a very simple explanantion.
The screen shot was taken after I reduces the core frequency to 400 MHz.
Setting the core frequency above 400 MHz makes the setting disappear.
Where I was wrong was thinking of that as an issue.
It's a normal behavior, running above 400 MHz does rquire to use the LDO.
Thank you again for your answers.
May this post help other users to avoid them doing the same mistake.

Hello,

your screen shot is from 1.14.1 not 1.15.1.

The attached screen shot to my original post shows that the item is missing.

I upgraded to 1.15.1 form a rather old version because the IOC has strong issue rendring the H755 configuration (blank screen).

Then I created a project for the Nucleo board and got a warning saying that the power option (SMPS DIRECT) was not valid.

Do you suggest that I should fully remoce CubeIDE and do a fresh install ?

In this case, is backuping the workspace, clearing the folder, installing a fresh copy and restoring the workspace form the backup a safe solution?

Thx

the latest version of CubeMX does show the option.
