LiteX Build Environment

The LiteX Build Environment is a tool for easily developing LiteX based systems. It was originally designed to make the TimVideos' HDMI2USB easy to develop, but has now expanded to support multiple projects.

Projects using LiteX Build Environment:
- HDMI2USB - The HDMI2USB project develops affordable hardware options to record and stream HD videos (from HDMI & DisplayPort sources) for conferences, meetings and user groups.
- FuPy - The aim of the FuPy project is to make MicroPython run on FPGAs using the LiteX & Migen+MiSoC technologies. This allows you to do full stack development (FPGA gateware & soft CPU firmware) in Python!

Important Terminology

Gateware - The FPGA configuration.
Soft CPU - A CPU running inside the FPGA.
Firmware - The software running on the soft CPU inside the FPGA.

Boards

The LiteX Build Environment supports a large number of FPGA boards, but not all boards can be used for all projects.

Firmware

HDMI2USB - The firmware currently used for the HDMI2USB project.
Bare Metal - Your own firmware running directly on the soft CPU in the FPGA.
Zephyr - Support for Zephyr RTOS.
Linux - Support for Linux.
