Worked on enhancing the Zephyr SDK installer in the nrfconnect/sdk-zephyr repository by improving cross-distribution support, specifically targeting Arch Linux environments. Addressed a setup reliability issue by adding the 'which' utility to Arch Linux dependencies, enabling the installer’s shell script to accurately verify the presence of CMake and wget. This change reduced false negatives during SDK initialization and streamlined onboarding for Arch-based developers. The work involved shell scripting, dependency management, and thorough documentation updates to ensure maintainability. Demonstrated a methodical approach to cross-distro compatibility, focusing on robust scripting practices and clear communication of changes for future scalability.
