A firsthand report from Embedded World 2025 in Nuremberg highlights five major trends reshaping embedded software development. Commercial tools like IAR are integrating with open-source frameworks such as Zephyr RTOS and modern DevSecOps pipelines. Zephyr 4.1 is gaining dominance with 700+ contributors and significant performance improvements including 46% faster preemptive scheduling. AI is pervasive across the show floor, from automated fuzz testing to schematic generation and edge NPUs. Multicore architectures with dedicated Neural Processing Units (e.g., STM32N6 with 600 GOPS) are becoming standard. DevOps and CI/CD practices, including hardware-in-the-loop testing and automated MISRA compliance, are finally going mainstream in embedded development.
