fx2lafw is a free/libre/open-source firmware for logic analyzers based on
the Cypress EZ-USB FX2(LP) chip.
-It is licensed under the terms of the GNU GPL (version 2 or later).
+It is licensed under the terms of the GNU GPL (version 2 or later), and uses
+additional helper code (fx2lib), licensed under the GNU LGPL (version 2.1
+or later).

Requirements
------------
-In order to build fx2lafw you need the 'sdcc' compiler.
-
-On Debian you can install it via:
+ - In order to build fx2lafw you need the 'sdcc' compiler.
+ On Debian you can install it via:
- $ apt-get install sdcc
+ $ apt-get install sdcc
-In order to transfer the firmware onto the FX2 chip, you can use cycfx2prog:
+ - You need libsigrok >= 0.1.1 in order to make use of fx2lafw. Earlier
+ versions didn't have support for FX2 devices using this firmware.
- $ apt-get install cycfx2prog
Building
--------
$ git clone git://sigrok.git.sourceforge.net/gitroot/sigrok/fx2lafw
$ cd fx2lafw
- $ git clone git://github.com/mulicheng/fx2lib.git
$ make
-Usage
------
- $ cycfx2prog -id=vvvv:pppp prg:<device>.ihx reset run delay:100
+Installation
+------------
+
+ $ sudo make install
+
+The generated *.fw files are installed into /usr/local/share/sigrok-firmware.
+
+You can override the install location like this:
+
+ $ sudo make install DESTDIR=/usr/share/sigrok-firmware
+
+
+fx2lib
+------
+
+The fx2lafw code uses a (slightly modified) "fx2lib" helper library.
+
+It was imported into fx2lafw from
+
+ git://github.com/ubixum/fx2lib.git
+
+as of Feb 12, 2012 (git hash "416c104cbd").
-You have to provide the USB VID/PID of the FX2 device (before firmware
-upload) using the -id parameter.
+The following files/directories were removed, as they're not needed
+for our purposes: CHANGELOG, COPYING*, docs/, examples/, fw/, and utils/.
-Replace <device>.ihx with the respective .ihx file from the
-hw/*/build/ directory, e.g. hw/saleae-logic/build/fx2lafw-saleae-logic.ihx.
