STM32CubeMX2 v1.2.0 released

We’re happy to announce that STM32CubeMX2 v1.2.0 has been released and is now available.

 

This release includes updates and improvements aimed at enhancing the user experience and supporting your development workflow with STM32.

 

What’s new

  • Improved robustness during project creation and opening, with earlier error detection and clearer notifications for Peripherals, NVIC, and EXTI
  • Improved robustness against missing or corrupted packs and resources, with initial error inventory coverage in DMA, Clock, EXTI, NVIC, and Project Creation
  • Improved overall user experience across Parts, Middleware, Pack Manager, Software Configuration, and Peripherals, including responsive design improvements
  • Added peripheral search and filtering, and text search in most configuration views
  • Added direct navigation from used EXTI lines to their corresponding configuration
  • Improved management of configurable parts composing a module, with more granular selection and control
  • Added middleware user experience enhancements and middleware version selection
  • Added pin label visibility from configuration views and restored board pinout constraints
  • Added support to install packs from an EmbSW package
  • Added one-step pack and dependency update
  • Added support for project update to newer compatible pack versions with breaking changes
  • Added access to installed pack license terms directly from disk
  • Added portable installation support
  • Added build profile selection in GUI (Debug/Release/Both)
  • Added STM32CubeMX2 Project Export support for raw format (without IDE project format)
  • Improved the project format naming to better identify targeted IDE
  • Added user preferences management through command-line interface (CLI), and improved user preferences maintainability
  • Added spread-spectrum clock support for supported STM32 devices
  • Improved overall performance and robustness
  • Customer-reported fixed issues:
    • Command-line interface (CLI) does not generate the build preset in CMake even though the project is generated successfully
    • FDCAN1 RX GPIO configuration not loading after peripheral configuration changes
    • Enhanced user experience related to pack update for already existing project
    • Missing validation for ADC clock frequencies above 36 MHz on STM32C5 devices
    • Improved access to EWARM patches in generated IAR projects
  • Other major fixed issues:
    • NMI IRQ line retrieval in the FLASH panel didn’t work anymore
    • Missing Timer selection option in HAL Time Base for projects created with earlier C5 packs
    • Incorrect red highlighting of DMA code in Code Preview after a second change
    • Dynamic mode for Code Preview not functional anymore
