Hello,
The following license is BSD but with an extra clause regarding binary
distribution, it should be okay I think but I just want confirmation it's not a
problem:
================================================================================
FatFs License
FatFs has being developped as a personal project of the author, ChaN. It is
free from the code anyone else wrote at current release. Following code block
shows a copy of the FatFs license document that heading the source files.
/*----------------------------------------------------------------------------/
/ FatFs - Generic FAT Filesystem Module Rx.xx /
/-----------------------------------------------------------------------------/
/
/ Copyright (C) 20xx, ChaN, all right reserved.
/
/ FatFs module is an open source software. Redistribution and use of FatFs in
/ source and binary forms, with or without modification, are permitted provided
/ that the following condition is met:
/
/ 1. Redistributions of source code must retain the above copyright notice,
/ this condition and the following disclaimer.
/
/ This software is provided by the copyright holder and contributors "AS IS"
/ and any warranties related to this software are DISCLAIMED.
/ The copyright owner or contributors be NOT LIABLE for any damages caused
/ by use of this software.
/----------------------------------------------------------------------------*/
Therefore FatFs license is one of the BSD-style licenses but there is a
significant feature. FatFs is mainly intended for embedded systems. In order to
extend the usability for commercial products, the redistributions of FatFs in
binary form, such as embedded code, binary library and any forms without source
code, does not need to include about FatFs in the documentations. This is
equivalent to the 1-clause BSD license. Of course FatFs is compatible with the
most of open source software licenses including GNU GPL. When you redistribute
the FatFs source code with any changes or create a fork, the license can also
be changed to GNU GPL, BSD-style license or any open source software license
that not conflict with FatFs license.
