Since Updating to new Version is always a lot of manual work i would kindly ask for a Change Log compared to the Major Version 6.4.0.

The new Features / Improvements may justify/not justify the move from 6.4.0 -> 6.4.1.

Hello @StefanH1,

A post is available on the homepage of the ST Motor control forum (as for MCSDK6.4.0) for main changes description.

This post is not available for the MCSDK6.4.1 version. Once downloaded, refer to the V6.4.1 main changes chapter in the Release Notes documentation available through Workbench tool > About > Documentations.

Thanks for your answer. I hoped for a easier solution than downloading and installing the latest version to get that Information.

i extracted release notes and posting here:

V6.4.1 / 11-July-2025

Main Changes

This version of the new Motor Control SDK 6 series (X-CUBE-MCDSK) is a bug fix release of the version 6.4.0.

Please note that the MCSDK executable is provided as a ST digitally signed executable.

Taking the opportunity of this new release, several topics reported through ST Community have been fixed :

Description ST Community links

TIM8 configuration does not work with 6step projectMCSDK6.3.2 GenerateCode Error about TIM8
BEMF ADC sampling time not taken from MCWBWhy are 3 ADC pins configured in 6-step BLDC SDK, but only Channel 13 is used in injected mode?
Hall sensor not working on 6.4Hall sensor not working on 6.4
Speed Loop PID Tuning in ESC001V1Speed Loop PID Tuning in ESC001V1

In addition to the fixes mentioned above, this delivery brings the following improvements :

  • 6Step algorithm:

    • Fixed issue for HALL sensors usage for a 6Step project.
  • FOC algorithm:

    • Fixed issue on ADC polarization affecting 1shunt topology for cortex M0/M0+ series (STM32C0, STM32G0, STM32F0)

    • Added ability to use Encoder and Hall sensors at the same time (main and auxiliary) (functionality available on specific B-G473E-ZEST1S board)

    • Hall sensors are not locked anymore in "Not Reliable" state if they are back on track. It allows a smooth STO-PLL -> Hall sensors dynamic transition.

Specific changes introduced in the ST Motor Control Workbench

  • Fixed 3shunt and 1 ADC Max Modulation Index computation.

Specific changes introduced in the ST Motor Control Board Manager

  • No changes.

Specific changes introduced in the ST Motor Control Board Designer

  • Improved MCU clock source management.

Specific changes introduced in the ST Motor Pilot

  • Fixed the display of board's thumbnails in profiler UI
