fx2lafw is a free/libre/open-source firmware for logic analyzers based on
the Cypress EZ-USB FX2(LP) chip.

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 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:build/fx2lafw.ihx reset run delay:100
+Copy the generated *.fw file for your device (e.g. fx2lafw-saleae-logic.fw)
+into the $prefix/share/sigrok-firmware directory (create it, if needed).
+
+Replace $prefix with the install prefix of sigrok, e.g. /usr or /usr/local.
+
+Example (assuming /usr/local as $prefix):
+
+ $ sudo mkdir /usr/local/share/sigrok-firmware
+
+ $ sudo cp hw/saleae-logic/build/fx2lafw-saleae-logic.fw \
+ /usr/local/share/sigrok-firmware
-You have to provide the USB VID/PID of the FX2 device (before firmware
-upload) using the -id parameter.
+The sigrok frontends (command-line or GUI) will automatically search for
+firmware files there and automatically use/upload them.
