January 2026 monthly summary for zephyrproject-rtos/zephyr. Key feature delivered: West interface now includes a reset command that reboots the board and integrates with the J-Link GDB reset flow, significantly improving debugging reliability and repeatability. Commit reference: 36ffd6350084cba61baca49c5209a9e678c64604. This work updates west command definitions and the runner to support the new reset capability, enabling developers to quickly reinitialize target hardware during tests. Major bugs fixed: None reported for this period. Overall impact and accomplishments: The new reset capability strengthens the Zephyr development workflow by providing a consistent, scriptable reboot path synchronized with J-Link GDB resets. This reduces time spent on debugging hangs related to incomplete resets and improves issue reproducibility across hardware targets. The change demonstrates effective cross-tool integration (West CLI, J-Link runner) and contributes to faster development cycles with more reliable board resets. Technologies/skills demonstrated: West CLI enhancements, J-Link GDB integration, scripting and tooling updates, version-controlled feature delivery, and clear commit hygiene (single clearly labeled commit).
