Freedom Studio

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 development boards.

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.

Completely Open Source
