fx2lafw
------------------------------------------------------------------------------

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).

Requirements
------------

In order to build fx2lafw you need the 'sdcc' compiler.

On Debian you can install it via:

  $ apt-get install sdcc

In order to transfer the firmware onto the FX2 chip, you can use cycfx2prog:

  $ 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

You have to provide the USB VID/PID of the FX2 device (before firmware
upload) using the -id parameter.

Replace <device>.ihx with the respective .ihx file from the
hw/*/build/ directory, e.g. hw/saleae-logic/build/fx2lafw-saleae-logic.ihx.
