Software

Dream it.
Build it.

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 Studio

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.
