CORE-V SDK is a packaged IDE and quick-start environment for importing, building, and debugging CORE-V sample applications. It brings together GDB/OpenOCD or QEMU launch configurations, register views, an integrated terminal, and FreeRTOS-aware task and queue inspection. The project is now inactive and its documented host matrix is limited to older x86 Windows and Linux versions with no Arm-host support, so it is best used to reproduce its original workflow rather than as the default SDK for a new project.

Verified adoption, contributor and lineage records, educational use, presentations, articles, and ecosystem data will be added incrementally from named sources.
corev-gcc is OpenHW's development fork of GCC for CORE-V-specific compiler work. It contains the complete GCC source tree and uses a development branch as the integration point for CORE-V changes, so it is relevant to toolchain maintainers investigating those patches rather than to application developers looking for a packaged compiler. The repository is inactive and is not the upstream GCC project; new standard RISC-V compiler work should normally begin with current upstream GCC.
corev-binutils-gdb is OpenHW's development fork of GNU Binutils and GDB for CORE-V-specific assembler, linker, binary-tool, and debugger changes. Its development branch tracks upstream Binutils while carrying CORE-V work intended for possible upstream submission. This inactive repository is useful when maintaining or auditing the historical CORE-V GNU toolchain, but it is not an official upstream distribution or a current end-user tool package.
CORE-V MCU DevKit contains the hardware-design artifacts for an evaluation board built around CORE-V MCU and the CV32E40P v1.0.0 core. The board combines a QuickLogic ArcticPro2 embedded FPGA, flash, on-board JTAG/debug, expansion and sensor interfaces, camera support, and AWS IoT ExpressLink connectivity; the repository provides KiCad sources and schematics rather than processor RTL. It is most useful to board designers and bring-up engineers who need a concrete hardware platform for the CORE-V MCU ecosystem.
