Michal Smola developed and enhanced embedded hardware support across multiple Zephyr repositories, focusing on NXP MCXL and MCXC platforms. He implemented device tree and driver updates in C and CMake to enable new board bring-up, improved clock and pin control, and expanded DMA-based testing. In nrfconnect/sdk-zephyr and kholia/zephyr, Michal addressed test harness reliability and introduced features like split-role interrupt support for I2C drivers, ensuring compatibility across diverse SoCs. His work included firmware and configuration management, hardware abstraction, and CI integration, resulting in robust, repeatable flashing, streamlined onboarding, and broader hardware validation for Zephyr-based embedded systems.
February 2026: Delivered targeted NXP hardware support enhancements for Zephyr and expanded DMA-based test coverage on FRDM-MCXC242, complemented by a Zephyr-compatibility macro in the HAL to align with linker constraints. These changes improve early SoC enablement, driver compatibility, and testing breadth across NXP platforms, driving faster onboarding and more robust validation.

In December 2025, delivered end-to-end MCXL family support across Zephyr forks (zephyrproject-rtos/hal_nxp and nxp-upstream/zephyr). Implemented hardware control and initialization for MCXL25x-based platforms, including pinctrl, device-tree, and clock management, integrated MCXL support into HAL_NXP, and added basic FRDM_MCXL255 board support. The work enables customers to use MCXL MCUs with Zephyr, aligns with Kconfig/CMake CI, and improves scalability for MCXL-based solutions.

July 2025 monthly summary for nrfconnect/sdk-zephyr: Delivered targeted improvements to expand hardware compatibility and stabilize test harnesses. Key feature delivered: i2c_mcux_lpi2c driver now supports split-role interrupts, enabling proper interrupt handling for SoCs with separate controller and target IRQ lines, broadening compatibility across NXP devices. Major bug fixed: accel_trig sample harness corrected configuration to avoid the 'no regex patterns configured' error, ensuring reliable harness interpretation after fixture additions. Overall impact: improved cross-SOC interoperability, reduced CI/test noise, and faster integration for customers using NXP platforms. Technologies demonstrated: embedded I2C (LPI2C) driver work, interrupt architecture, test harness customization (regex and one_line types), and CI stability practices.

December 2024 monthly summary focusing on delivering a critical bug fix to the LinkServer flashing loop in telink-semi/zephyr, enabling reliable and repeatable flashing across devices. The change adjusted the MCU security state from fully secure (0xFF) to less secure (0xFE), implemented via device tree and flash configuration, enabling repeated flash cycles and reducing manual intervention. This work strengthens CI/test reliability and accelerates hardware bring-up.
