RuyiSDK Community Weekly Digest (August 21 Edition)

[myal]

RuyiSDK Overview

RuyiSDK is an open-source project initiated by PLCT Lab, designed to provide RISC-V developers with a convenient and comprehensive development environment. It offers:

• Latest hardware information and software support
• Supported devices list
• Software resources including OS images (e.g. RevyOS), toolchains, package managers

​Core Objectives:

1. Establish a complete development ecosystem for RISC-V
2. Promote RISC-V as a mainstream architecture
3. Build an active developer community
4. Internationalize RuyiSDK for global RISC-V developers

PLCT Lab aims to lead in open-source compilation technology, driving innovation in toolchains and runtime systems while cultivating 10,000 top-tier compilation experts.
