Nuclei Studio VSCode

Nuclei Studio VSCode is a Visual Studio Code extension for developing, building, and debugging embedded applications on Nuclei RISC-V processors. It works on top of the Nuclei Studio IDE, bringing its toolchains, SDKs, and debug servers into VS Code.

Features

Project Management

• Create projects from templates (Hello World C/C++, board/SoC-based projects)
• Import, export, rename, and switch between projects in the workspace view
• Project content view with file operations, per-file build settings, and build configurations (Debug/Release)

Build & Debug

• Build, clean, and rebuild projects with one click
• Debug on hardware or simulators via OpenOCD, J-Link, QEMU, or Nuclei Model, with launch file management
• Live Watch view for real-time variable monitoring, plotting, and CSV logging during debug

SDK & Package Management

• Manage SDKs and install NPK component packages (SDK/SSP/BSP)
• Open projects in a terminal or Git Bash

Quick Start

1. Download and install the Nuclei Studio IDE.
2. Install this extension, then open the Nuclei Studio VSCode view in the activity bar and follow the Get Started with Nuclei Studio VSCode walkthrough.
3. Set nucleiStudio.installFolder to your Nuclei Studio installation folder — toolchain, OpenOCD, and build tool paths are derived from it automatically.
4. Install the NPK packages your project needs via NPK Package Management, then create or import a project and start building and debugging.

Requirements

• Nuclei Studio IDE installed; Nuclei Studio VSCode works on top of it
• A Nuclei RISC-V toolchain (GCC / Clang / ZCC) and OpenOCD, configurable via the extension settings
• Companion extensions (installed automatically from the Marketplace): ms-vscode.vscode-serial-monitor, eclipse-cdt.cdt-gdb-vscode, eclipse-cdt.memory-inspector, eclipse-cdt.peripheral-inspector

Extension Settings

This extension contributes the following settings:

• nucleiStudio.installFolder: Nuclei Studio IDE installation folder
• nucleiStudio.buildToolsFolder: Build tools folder
• nucleiStudio.riscvToolchain.*.path: Paths to the various RISC-V toolchains
• nucleiStudio.openocd_path / nucleiStudio.openocd_executable: OpenOCD location
• nucleiStudio.jlink_path / nucleiStudio.jlink_gdbserver: SEGGER J-Link location
• nucleiStudio.nucleimodel_path / nucleiStudio.nucleimodel_executable: Nuclei Model location
• nucleiStudio.npk.globalPath / nucleiStudio.npk.userPath: NPK package paths
• nucleiStudio.liveWatch.*: Live Watch sampling interval, variable/plot limits, and CSV auto-save options

Release Notes

0.3.0

First official release of Nuclei Studio VSCode, released together with Nuclei Studio 2026.10 (0.3.0 is the extension version; 2026.10 is the version of the whole Nuclei Studio package, including the IDE, toolchain, OpenOCD, QEMU, and Nuclei Model):
