PROFILE

Andrzej Tlomak

Worked extensively on the Phoenix-RTOS ecosystem, delivering fourteen features and resolving critical bugs across core repositories such as phoenix-rtos-project and phoenix-rtos-devices. Focus areas included embedded networking, SpaceWire driver development, and robust build system enhancements. Leveraged C, Makefile, and YAML to implement device driver modularization, CI/CD automation, and hardware configuration for platforms like sparcv8leon-gr740-mini and riscv64-gr765-vcu118. Improved system reliability by introducing compile-time checks, memory safety assertions, and expanded test coverage in phoenix-rtos-tests. Emphasized maintainability and traceability by aligning code changes with Jira issues, updating submodules, and refining validation logic for hardware initialization and runtime stability.

Apr 1, 2026

April 2026 monthly summary for phoenix-rtos-project: Implemented RISC-V board configuration and SpaceWire SPWRTR enhancements to improve initialization reliability and runtime stability. The work focused on adding SPWRTR port count and AMBA count constants, introducing a clock divider for run-state in submodules, and enforcing stricter port number checks in spacewire/grspwrtr. Updated submodules reflect these changes, aligning with JIRA CSAT-225. These improvements reduce configuration errors, accelerate board bring-up, and strengthen SPWRTR reliability across supported hardware platforms.

Oct 1, 2025

2025-10 monthly summary: Delivered SPW_MAX_PACKET_LEN configuration for riscv64-gr765-vcu118 to enable reliable SPW data transmission; refreshed Phoenix-RTOS submodules (libphoenix, phoenix-rtos-build, phoenix-rtos-lwip, phoenix-rtos-ports) with fixes and enhancements including better floating-point formatting and architecture-specific build configurations; driver logic improvements across the stack. No major bugs fixed this month; emphasis on feature delivery, stability, and maintainability.

September 2025

14 Commits • 7 Features

Sep 1, 2025

September 2025 monthly summary for Phoenix-RTOS across repositories (phoenix-rtos-project, phoenix-rtos-build, phoenix-rtos-tests, phoenix-rtos-kernel, phoenix-rtos-devices). Focused on SpaceWire enhancements, router/device reliability, test infrastructure expansion, and build-system optimization. Key outcomes include optimized SpaceWire resource usage, expanded driver and test coverage for SPWR2/SPWRTR, stronger memory-safety checks, and faster CI/build cycles driven by LWIP integration and an EU-binutils mirror.

August 2025

Aug 1, 2025

August 2025 delivered foundational networking support and hardware identifiers across Phoenix-RTOS projects, enabling production-ready networking on a new platform and expanding kernel hardware support. Key outcomes include lwIP + GRETH integration for sparcv8leon-gr740-mini and a GRSPW2 DMA identifier in ambapp.h (CSAT-157, CSAT-160). No major bugs fixed this month; focus was on platform readiness, code quality, and maintainability. Business value: broader device interoperability, faster time-to-market for new hardware, and a solid base for future network features. Technologies demonstrated: embedded networking (lwIP), GRETH Ethernet, AMBAPP header updates, and platform export-path considerations.
