PROFILE

Karkadiusz

Worked on expanding and stabilizing cross-architecture test automation for the phoenix-rtos-tests and phoenix-rtos-project repositories, focusing on the aarch64a53-zynqmp-qemu target. Enhanced CI/CD pipelines and system integration by updating workflow matrices, tuning test harness timeouts, and improving build system configuration. Addressed reliability issues by fixing 64-bit pointer formatting in C, introducing dynamic test loop configuration, and excluding flaky test cases to reduce CI noise. Leveraged C, Python, and YAML to deliver robust embedded systems testing, submodule management, and system programming improvements, resulting in faster feedback cycles, more reliable emulator-based validation, and improved build and test infrastructure across the project.

In Aug 2025, stabilized QEMU tests for the aarch64a53-zynqmp target in phoenix-rtos-tests by tuning the test harness timeouts and aligning the emulated target initialization time with the slower performance observed on this configuration. This work reduced premature test failures and improved feedback quality for CI on constrained or slower emulated targets.
