PROFILE
Bohdan Hunko
Worked on the zephyrproject-rtos/trusted-firmware-m repository, delivering features and fixes that enhanced platform portability, build reliability, and secure firmware development. Leveraged C, CMake, and embedded systems expertise to implement configurable stack sizes, optimize build processes, and integrate secure metadata management aligned with Infineon extensions. Improved debugging by refining exception logging and integrating non-secure log systems, while also addressing compiler warnings and stabilizing CI pipelines. Refactored build system logic for cross-platform compatibility and streamlined BSP configuration, reducing maintenance overhead. The work demonstrated depth in system programming, configuration management, and secure software practices, supporting robust multi-platform firmware integration and maintainability.

Feb 1, 2026February 2026 highlights: Delivered essential platform and security enhancements for trusted-firmware-m in zephyrproject-rtos. Key work focused on four feature areas that drive business value: (1) Zephyr Non-Secure log system integration improving observability and debugging across secure/non-secure domains by configuring SCB and related memory map/pin/interrupt settings; (2) Cacheable FPU settings with user overrides enabling flexible platform tuning at build time; (3) Platform SVC added to retrieve original psa_call vectors, exposing original base addresses and lengths for SRF service functionality; (4) Infineon platform updates with crypto acceleration and platform-specific optimizations. There were no explicit bug fixes recorded this month; the emphasis was on feature delivery and platform readiness to accelerate integration with Zephyr and SRF workflows. Commit-level references are provided for traceability.

Jan 1, 2026January 2026: Delivered BSP Config Header Portability Enhancement in trusted-firmware-m, enabling uniform cross-platform handling and simplifying platform porting. The change moves BSP config header handling into a common install.cmake, reducing per-platform CMake logic and improving maintainability. No major bugs fixed this month; stabilization efforts continue. Impact: faster onboarding of new platforms, reduced maintenance, and clearer build configuration across Zephyr Trusted Firmware integration. Technologies demonstrated include CMake, cross-platform build automation, target_compile_definitions, and install script-based porting.

Dec 1, 2024December 2024 — zephyrproject-rtos/trusted-firmware-m monthly summary focused on stabilizing the Platform Build System (PS HAL) integration and improving build reliability. A syntax error in CMakeLists.txt was fixed by correcting the conditional that includes tfm_hal_ps.c based on PLATFORM_DEFAULT_PS_HAL, ensuring proper behavior when PLATFORM_DEFAULT_PS_HAL=OFF. This change was tracked under commit 3a302974298d0dca9a2b305c6efac4be4d55d93e (Build: Fix Cmake syntax).

Oct 1, 20242024-10 monthly summary for zephyrproject-rtos/trusted-firmware-m. Key deliverables focused on configurability and developer productivity, enabling broader platform support and faster debugging cycles. Delivered two primary improvements: (1) Configurable SPM thread stack size by making CONFIG_TFM_SPM_THREAD_STACK_SIZE re-definable in the configuration template, enabling platform-specific memory management across hardware variants; and (2) Improved exception logging readability by refactoring the logging format for callee-saved registers (added a newline before the register list) to streamline crash analysis. Impact: Greater platform portability and faster debugging with clearer crash reports, reducing time-to-tune memory settings and diagnose faults in multi-variant deployments. Note: No explicit major bugs fixed were reported for this period; the logging improvement and stack-size configurability contribute to stability and maintainability.
