PROFILE
Felix Monninger
Worked on the esrlabs/openbsw repository, delivering features and reliability improvements for embedded transport and network systems over five months. Developed cross-bus routing configurability and enhanced build stability using C++ and CMake, enabling flexible deployment across CAN, SELFDIAG, and Ethernet buses. Integrated Rust components by wrapping C-based stdout functions for modular I/O, and unified transport configuration testing with Python scripting and code refactoring. Addressed protocol scheduling bugs and streamlined dependencies to reduce maintenance overhead. Introduced tester address translation for multi-bus compatibility and improved repository hygiene with version control best practices, focusing on maintainable, portable solutions for embedded and networked environments.

May 1, 2026May 2026 monthly summary focusing on delivering cross-bus compatibility improvements, repository hygiene, and tooling improvements that reduce integration risk and maintenance burden. Key outcomes include cross-bus tester address translation for the transport router, a Rustfmt treefmt workflow wrapper to improve formatting usability, and repository housekeeping by ignoring build artifacts. Business value highlights: - Enhanced interoperability between 1-byte and 2-byte tester addressing across CAN, SELFDIAG, and DoIP buses, reducing integration effort and enabling seamless ETH <-> SELFDIAG testing. - Cleaner codebase and build hygiene through targeted refactoring and documentation alignment, improving maintainability and onboarding. - Resilient formatting workflow and CI configuration to prevent formatting-related failures in environments where rustfmt is unavailable.

Mar 1, 2026In March 2026, completed a targeted bug fix in esrlabs/openbsw to correct the DoIpServerSystem protocol send job count, improving reliability and scheduling accuracy for DoIp communications. The change updates the DoIpServerSystem header to reflect the actual number of protocol send jobs, reducing risk of mis-scheduling and processing delays. This work was delivered via a focused patch and tracked with the commit resolving the issue.

Feb 1, 2026February 2026 (2026-02) monthly summary for esrlabs/openbsw: Implemented a cross-language stdout abstraction and Rust integration to enable robust Rust-based I/O within the application. Delivered a new console_out Rust crate that wraps the C function for standard output behind core::fmt::Write, ported from the openbsw-console-out artifact, and integrated it with rust_hello_world. Updated rust_hello_world staticlib to depend on console_out and expose a rust_hello_world() FFI function that prints 'Hello from Rust!' to stdout, invoked from app.cpp when BUILD_RUST is enabled. Ported the crate into libs/rust and aligned the build with the BUILD_RUST flag to enable opt-in Rust paths.

Jan 1, 2026January 2026: Delivered key features and stability fixes for esrlabs/openbsw, focusing on cross-bus routing configurability and build-time stability. Key outcomes include enabling Flexible Ethernet support with conditional Ethernet bus routing to support CAN and SELFDIAG buses even when Ethernet is disabled, and improving DoIP/ETHERNET build stability by removing a problematic include and replacing estd::array with etl::array for better compatibility. These changes reduce build failures in Ethernet-disabled configurations and broaden the portability of the transport router across projects, delivering tangible business value for multi-bus deployment scenarios.
