fx2lafw is an open-source firmware for Cypress FX2 chips which makes them usable as simple logic analyzer hardware.

It is licensed under the terms of the GNU GPL (version 2, or later) and written in C, using sdcc as compiler, and fx2lib as helper library.

Note: This is work in progress. It does NOT work, yet!

Hardware overview

The fx2lafw firmware is meant to work on any FX2-based hardware, including logic analyzers, FX2 eval boards, or other hardware which has this chip on-board.

Here's a quick overview of some of the relevant hardware information we have about the various devices:
