Arty Z7 Buildroot - Part Two

Buildroot Digilent Arty-Z7 - Part 2

In our last post we went over how we can create Linux image for the Arty Z7 using buildroot. The obvious next step is to build our firmware using buildroot. However this is not something that is just available. So let’s add this to our buildroot setup!

Start of a journey

What started as a wild idea a few months ago is suddenly turning into a real idea. We are starting our journey to try spread some knowledge gathered through consulting, R&D and enthousiasm. Our goal is to share as much of our technical endevours as possible be it firmware, hardware schematics or software.

Everything will or should at some point be available on Github
