HiFive1 Rev B is an upgrade to our low-cost development board featuring the Freedom E310. It’s the best way to start prototyping and developing your RISC‑V applications.
HiFive1 is a low-cost, Arduino-compatible development board featuring the Freedom E310. It’s the best way to start prototyping and developing your RISC‑V applications.
HiFive Unleashed is the ultimate RISC‑V development board. Featuring the Freedom U540—the world’s first-and-only Linux-capable, multi-core, RISC‑V processor—the HiFive Unleashed ushers in a brand-new era for RISC‑V.
Freedom E SDK
The Freedom E SDK is a repository of demo programs, industry standard benchmarks, and board support packages (BSPs) for our hardware platforms. Running benchmark code on our development boards is as easy as building a single Makefile target.
Freedom Studio is the fastest way to get started programming with your SiFive hardware. Freedom Studio is built on top of the popular Eclipse IDE and packaged with a prebuilt toolchain and example projects from the Freedom E SDK. Freedom Studio is compatible with all SiFive RISC-V development boards.
We highly recommend downloading and reviewing the Freedom Studio User Manual before downloading and installing Freedom Studio. This manual has important information about preparing your host system to help you get up and running as quickly as possible. Please note that the Freedom Studio IDE no longer runs on CentOS 6.
GCC Toolchain and Emulator
Save time by using one of our prebuilt toolchains which contain all the tools necessary to compile and debug programs on SiFive products. No hardware, no problem as the QEMU emulator packages can be used to test software applications without hardware. Our toolchain and emulator distributions have been carefully packaged to support both 32-bit & 64-bit ISAs.
Freedom U SDK
The Freedom U SDK is a repository containing everything needed to build a Linux-based board support packages (BSP) targeting SiFive hardware and emulation platforms.
A vibrant third-party ecosystem has evolved around the free and open RISC‑V ISA. The following tools are not developed nor maintained by SiFive, but may be worth considering for your next project.
Ashling is a world-class technology partner offering integrated solutions, tools, and design services that are at the heart of the embedded environment. Ashling RiscFree™ C/C++ for RISC-V, is a fully integrated development tool environment that includes an IDE, compiler, debugger, and Opella-XD JTAG probe ready to use with SiFive’s RISC-V Core IP products. A single download and install provides out of the box functionality and support for SiFive IP cores. Ashling brings in the added value of offering tools customization of any ISA extension, for both compiler and debugger, to support SiFive’s customer base.
GNU MCU Eclipse
GNU MCU Eclipse is an open source project that includes a family of Eclipse plug-ins and tools for multi-platform embedded development, based on GNU toolchains. The RISC‑V architecture is fully supported, and the Eclipse plug‑ins allow users to create and build C/C++ projects. The debugging plug-ins support SEGGER J‑Link, OpenOCD, and QEMU—and include a detailed peripheral register viewer.
