  • Smarter ELF debugging

    Improved external ELF file debugging, with source views and debug-only project creation for CI/CD pipelines or other toolchains. 

  • New RTOS awareness plugins

    Extended support for Zephyr RTOS, PX5, Cesium OS3, and Cesium OS2. 

  • New device support

    Expanded coverage including Raspberry Pi, ST, NXP, Renesas, Texas Instruments, Analog Devices, Microchip, GigaDevice, Nuvoton, AutoChips, SemiDrive, ABOV, Lanshan, Puya, TMC, XHSC, YTMicro, and ZhiXin.

Version: 9.60.4
  • Improved CMake support

    CMake files can now be directly read by the IAR Embedded Workbench IDE to populate the project manager view, allowing the flexibility of CMake to be mirrored in IAR Embedded Workbench and empowering the user with the IAR C-SPY debug experience as well as building. Enables support for importing, building, and debugging projects based on CMake in IAR Embedded Workbench.

  • Cortex-M52 support
  • C-STAT support for MISRA C:2023

    MISRA C:2023, also known as MISRA C Third Edition, Second Revision, is now supported. It incorporates MISRA C:2012 amendments 2 (AMD2), 3 (AMD3) and 4 (AMD4), plus technical corrigendum 2 (TC2). MISRA C:2023 incorporates support for C11 and C18 language features.
