A VS Code extension for quickly flashing firmware using pyOCD. The extension auto-discovers ELF files in the workspace, provides target selection, and offers a one-click flash workflow.
Features
Status bar ⚡ Flash button to start flashing with a single click.
Auto-detects .elf files in the workspace (prefers build/**).
If no target is configured, prompts to select one and continues flashing.
Shows a loading notification while fetching pyOCD targets.
Reuses a terminal named PyOCD Loader to keep flash output history.
Requirements
pyocd must be installed and available on PATH (install with pip install pyocd).
Python 3 is recommended.
Usage
Run PyOCD: Select Target from the command palette to choose your board target. If you run PyOCD: Flash without a configured target, the extension will prompt you to select one.
Build your project to produce a .elf file (commonly under build/).
Click the ⚡ Flash status bar button on the right or run PyOCD: Flash, pick the ELF file, and wait for the flashing to complete.
Configuration
pyocd-one-click-loader.target (string): Target name to use for pyOCD (e.g. stm32f407vgtx). Stored at workspace level.
Troubleshooting
No .elf files found: build the project or ensure your ELF is in the workspace (check build/).
pyOCD not found: run pyocd --version in a terminal to verify installation.
