The Arm CMSIS Debugger extension pack for VS Code is a powerful, GDB/MI-based debug platform for Arm Cortex-M devices.
Key Features: - Supports single and multi-core systems - Built-in RTOS awareness: FreeRTOS, RTX, ThreadX, Zephyr - Works with a wide range of debug adapters: CMSIS-DAP (ULink, MCULink, NuLink), J-Link, ST-Link - Can be combined with other VS Code debug extensions (e.g. Linux app debugging)
Why This Matters: VS Code debug tools for Cortex-M are fragmented and incomplete. Arm’s open-source extensions aim to close these gaps by delivering a robust foundation that is extensible with domain specific features for device configuration, Edge AI, and more.
