5 fx2lafw is a free/libre/open-source firmware for logic analyzers based on
6 the Cypress EZ-USB FX2(LP) chip.
8 It is licensed under the terms of the GNU GPL (version 2 or later), and uses
9 additional helper code (fx2lib), licensed under the GNU LGPL (version 2.1
16 - In order to build fx2lafw you need the 'sdcc' compiler.
17 On Debian you can install it via:
19 $ apt-get install sdcc
21 - You need libsigrok >= 0.1.1 in order to make use of fx2lafw. Earlier
22 versions didn't have support for FX2 devices using this firmware.
28 $ git clone git://sigrok.git.sourceforge.net/gitroot/sigrok/fx2lafw
36 Copy the generated *.fw file for your device (e.g. fx2lafw-saleae-logic.fw)
37 into the $prefix/share/sigrok-firmware directory (create it, if needed).
39 Replace $prefix with the install prefix of sigrok, e.g. /usr or /usr/local.
41 Example (assuming /usr/local as $prefix):
43 $ sudo mkdir /usr/local/share/sigrok-firmware
45 $ sudo cp hw/saleae-logic/build/fx2lafw-saleae-logic.fw \
46 /usr/local/share/sigrok-firmware
48 The sigrok frontends (command-line or GUI) will automatically search for
49 firmware files there and automatically use/upload them.
55 The fx2lafw code uses a (slightly modified) "fx2lib" helper library.
57 It was imported into fx2lafw from
59 git://github.com/ubixum/fx2lib.git
61 as of Feb 12, 2012 (git hash "416c104cbd").
63 The following files/directories were removed, as they're not needed
64 for our purposes: CHANGELOG, COPYING*, docs/, examples/, fw/, and utils/.
