5 | The sigrok project aims at creating a portable, cross-platform, | |
6 | Free/Libre/Open-Source signal analysis software suite that supports various | |
7 | device types (such as logic analyzers, oscilloscopes, multimeters, and more). | |
8 | ||
9 | sigrok-firmware-fx2lafw is a Free/Libre/Open-source firmware for logic | |
10 | analyzers based on the Cypress EZ-USB FX2(LP) chip. | |
11 | ||
12 | ||
13 | Status | |
14 | ------ | |
15 | ||
16 | sigrok-firmware-fx2lafw is in a usable state and has had official | |
17 | tarball releases. | |
18 | ||
19 | ||
20 | Requirements | |
21 | ------------ | |
22 | ||
23 | - git | |
24 | - make | |
25 | - autoconf >= 2.63 | |
26 | - automake >= 1.11 | |
27 | - sdcc (>= 2.9.0) | |
28 | ||
29 | Notes: | |
30 | ||
31 | - In order to build fx2lafw you need the 'sdcc' compiler (>= 2.9.0). | |
32 | On Debian you can install it via: | |
33 | ||
34 | $ apt-get install sdcc | |
35 | ||
36 | This project has been tested to work with sdcc 2.9, 3.0, 3.1, and 3.2. | |
37 | ||
38 | - You need libsigrok >= 0.1.1 in order to make use of fx2lafw. Earlier | |
39 | versions didn't have support for FX2 devices using this firmware. | |
40 | ||
41 | ||
42 | Building and installing | |
43 | ----------------------- | |
44 | ||
45 | In order to get the sigrok-firmware-fx2lafw source code and build it, run: | |
46 | ||
47 | $ git clone git://sigrok.org/sigrok-firmware-fx2lafw | |
48 | $ cd sigrok-firmware-fx2lafw | |
49 | $ ./autogen.sh | |
50 | $ ./configure | |
51 | $ make | |
52 | ||
53 | For installing sigrok-firmware-fx2lafw: | |
54 | ||
55 | $ make install | |
56 | ||
57 | The generated *.fw files are installed into /usr/local/share/sigrok-firmware. | |
58 | ||
59 | You can override the install location like this: | |
60 | ||
61 | $ ./configure --prefix=/usr | |
62 | ||
63 | See INSTALL or the following wiki page for more (OS-specific) instructions: | |

66 | ||
67 | ||
68 | Pre-built firmware files | |
69 | ------------------------ | |
70 | ||
71 | There are also pre-built firmware files that can be used without having | |
72 | to build them from source. You can download those from SourceForge: | |
73 | ||
74 | http://sourceforge.net/projects/sigrok/files/binary/sigrok-firmware-fx2lafw/ | |
75 | ||
76 | ||
77 | fx2lib | |
78 | ------ | |
79 | ||
80 | The fx2lafw code uses a (slightly modified) "fx2lib" helper library. | |
81 | ||
82 | It was imported into fx2lafw from | |
83 | ||
84 | git://github.com/ubixum/fx2lib.git | |
85 | ||
86 | as of Feb 12, 2012 (git hash "416c104cbd"). | |
87 | ||
88 | The following files/directories were removed, as they're not needed | |
89 | for our purposes: CHANGELOG, COPYING*, docs/, examples/, fw/, and utils/. | |
