STM32 MCUs Software development tools

An issue has been identified in STM32CubeIDE 1.19.0 and earlier versions where a download error pop-up may appear during data updates. This issue does not prevent STM32CubeIDE from functioning properly. To continue: click OK twice.  STM32CubeIDE should then operate normally.  Optional workaround If this pop-up impacts your workflow, you can disable the Auto-Refresh feature: Go to Window → Preferences In the search field, type Firmware Updater Select: Offline Mode No Auto-Refresh at Application start  Notes If Auto-Refresh is disabled, STM32CubeIDE will use the local cube-finder-db.zip file and will not automatically retrieve updates.  Manual update If needed, you can manually update the data via: Help → STM32Cube Updates → Check for Target Selector Device Database Updates  

Dear ST Community members, At the moment, STM32CubeMX2 uses the latest packs available on the public server.A script is available for a specific use case if you prefer not to start a project with the most recently published pack version.This script can be used when a project needs to be created or maintained with the STM32C5 v2.0.0 packs, instead of the most recent version available.If this matches your situation, feel free to use the script as an alternative.Where to get the script: check How to start with previous versions of HAL2 For more details on how to use it, please check the README. If you have any feedback, please don’t hesitate to share it with us in the:  STM32CubeMX2 (MCUs) - STMicroelectronics Community  The STM32CubeMX2 Team

An issue has been identified in which STM32CubeMX displays a download error pop-up during data updates.  This issue does not prevent STM32CubeMX from working properly. To continue: Click OK  twice. After these steps, STM32CubeMX can operate normally. If this pop-up affects your workflow, disable the Auto-Refresh feature: In Help → Connection and Updates, select No Auto- Refresh at Application start.  Please note that if Auto-Refresh is disabled, STM32CubeMX uses the local cube-finder-db.zip file and does not retrieve updates automatically. If needed, manually update the data: Help → Refresh Data A fix is in progress in a future version.

Dear STM32CubeProgrammer Community, I hope you are all doing well.   Over the past months, you may have received an email from me, either through the STM32CubeProgrammer survey or on other topics like CSAT or Raspberry Pi support. First, I would like to thank you a lot for all your contributions and feedback, we highly appreciate them, your voice matters !   We’re currently working on improving STM32CubeProgrammer’s usability and would like to 1. reduce the number of repetitive / low added value actions you have to perform, and 2. provide you with clearer error messages.   We need your contributions to address priority scenarios.   Could you please share in the comments which improvements, use cases, or automated actions you would like to see in the tool to make your daily work easier ? This includes typical errors you often get that you think the tool could prevent or handle automatically, as well as any “why do I have to do this myself every time?” situation you e
