BrightSign Source Code
Corresponding to brightsign-v3.8.34 binary release
2012-04-05

* Introduction

Parts of the firmware for this BrightSign product make use of "Open Source"
software under various different licenses. Under the terms of some of these
licenses we are required to provide the source code used to generate the
binaries we distribute. This file describes the components and where the
source code can be found.

Note that the firmware also contains many other proprietary parts from
BrightSign and third parties. The source code for these parts is not
provided.


* Toolchain

Different parts of the firmware are compiled using different
toolchains. Some parts are compiled with ELDK-4.0 and some with a custom
built toolchain.

The binary distribution of ELDK-4.0 for x86 is included in the file
ELDK-4.0-mips-2006-01-17.tar.bz2 and the sources are provided in the file
ELDK-4.0-mips-200601-17-source.tar.bz2. This also includes the source code
for the C library and other runtime components.

The stock glibc source used as part of the custom toolchain is included in
the file glibc-*.tar.bz2 and our patches are provided in the file
glibc-*-brightsign-3.8.34-patches.tar.bz2.


* Linux kernel, buildroot, u-boot and other GPL sources

These are provided in the form of a build system with overlays and patches
against a series of tarballs. You can find the GPL sources in the file
stb225-gpl-brightsign-3.8.34.tar.bz2, sources under other open source
licenses required in order to compile the GPL sources in the file
stb225-open-brightsign-3.8.34.tar.bz2 and the tarballs required to build
the software in stb225-tarballs-brightsign-3.8.34.tar.

Unless otherwise marked files that originate from the tarball named
stb225-gpl-brightsign-3.8.34.tar.bz2 are licensed under GPL v2 - see
stb225/etc/licensing/gpl/gpl-2.0.txt.

Unless otherwise marked files that originate from the tarball named
stb225-open-brightsign-3.8.34.tar.bz2 are licensed under NXP BSD - see
stb225/etc/licensing/nxp_bsd.txt.

The easiest way to reveal the full source code is to untar the two .tar.bz2
files into a directory and the tarballs .tar file into a subdirectory
thereof named stb225_tarballs. Please see the build instructions in
stb225/etc/licensing/README_gpl.txt. You may wish to set the MIPSTOOLS
environment variable to point at your toolchain before following the
instructions.


* libhzip

This is a customised version of Mathias Hasselmann's libzip code partially
renamed to avoid confusion with other libraries named libzip. The Makefile
now generates a shared library too. The source code can be found in
libhzip-brightsign-3.8.34.tar.bz2. This library is licensed under the
GNU LGPL v2.1 - see the file COPYING within the tarball.


* iguanaIR

This is a stock version of the IguanaWorks USB IR transceiver driver
tarball. BrightSign uses this component unchanged. See
http://iguanaworks.net/ . Parts are licenses under the GNU GPL v2 and parts
are licensed under the GNU LGPL v2.1 - see the files COPYING and
COPYING-LGPL within the release.


* libmicrohttpd

BrightSign uses a lightly patched version of the libmicrohttpd library. It
is licensed under the GNU LGPL v2.1 - see the file COPYING within the
tarball. Patch files accompany the tarball.

* open-zwave

This is a customised version of the open-zwave library (subversion revision 164), 
that has been slightly extended for our purposes. We have added another linux "example" 
program that allows for the controlling of lamp modules. The source code can be found in
openzwave-brightsign-3.8.34.tar.bz2. This library is licensed under the
GNU LGPL 3.0 - see the source files within the tarball.
