A Visual Studio Code extension that enhances debugging for ARM Cortex-M microcontrollers and other embedded targets via GDB servers like J-Link, OpenOCD, pyOCD, and ST-LINK. It adds SWO/RTT decoding, live ITM data graphing, RTOS thread awareness, disassembly support, and multi-core debugging.

Use cases

• debug firmware on an STM32 with ST-LINK from VS Code
• decode SWO/ITM output and graph variables live while debugging a Cortex-M board
• debug RTOS threads and call stacks on an embedded target
• use SEGGER RTT console output during embedded debugging
• step through disassembly and set instruction breakpoints on a microcontroller
• debug RISC-V or Xtensa embedded targets through a GDB server

When to choose

• you develop Cortex-M (or similar embedded) firmware and want rich debugging inside VS Code
• you need SWO, ITM, or RTT decoding and live graphing of target data
• you need multi-core or RTOS-aware debugging with J-Link, OpenOCD, or pyOCD

When to avoid

• you debug only desktop or web applications with no embedded hardware
• you use a debugger or probe not supported by any of the integrated GDB servers
• you need ETM trace over SWO, which is not supported
