From the project

testing the cgra chip

This repo provides firmware examples, flash programming and diagnostic tools for testing Open MPW and chipIgnite projects using Caravel. It also provides schematics, layout and gerber files for PCB evaluation and breakout boards.

To program Caravel, connect the evaluation board using a USB micro B connector.
