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.
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:

All devices use a 24MHz crystal.
Download
$ git clone git://sigrok.git.sourceforge.net/gitroot/sigrok/fx2lafw
Usage
Building sigrok
- Build and install latest git head sigrok for your platform, see e.g. Linux.
- When building libsigrok, instead of ./configure do
$ ./configure --enable-fx2lafw --disable-saleae-logic
- Follow all other steps as normal.
Install udev rules file
These steps prevent the need to run sigrok as superuser.
- Copy the udev rules from sigrok/libsigrok/contrib/z60_libsigrok.rules to /etc/udev/rules.d/.
- Restart udev: sudo /etc/init.d/udev restart.
Building fx2lafw
$ cd fx2lafw $ git clone git://github.com/mulicheng/fx2lib.git $ make $ sudo cp build/*.fw /usr/local/share/libsigrok/firmware/
Where /usr/local is your installation prefix.
Test
$ sigrok-cli -D
If everything has worked, sigrok can now see your fx2lafw device, ready for use.
