- COPYING
- =======
- Describes the terms under which Nuttx is distributed. A copy of the BSD-
- style licensing is included in this file. In my words -- I believe that you
- should free to use NuttX in any environment, private, private, commercial,
- open, closed, etc. provided only that you respect the modest copyright
- notices as described in license (below), respect Trademarks, and include a
- copy of the BSD license. Please feel free to contact me if you have any
- icensing concerns.
- Tool Licenses
- -------------
- Tools under the nuttx/tools directory are not intended for binary
- distribution. You may find other licensing on individual tools in that
- directory. If you intend to redistribute these tools in binary form, please
- respect the individual license of each tool as identified in the file header
- of the tool source files.
- Copyright Date Notation
- -----------------------
- Copyright information is provided in the header of each file. This
- copyright information includes the name of the copyright holder and the
- year(s) in which copyrighted additions to the file were made to the file.
- A comma (',') is used to separate years in the list of years. A hyphen ('-')
- is used as a more compact notation when additions were made over several
- consecutive years. So for example, "2007, 2011" would mean that copyrighted
- additions were made during the years of 2007 and 2011 whereas "2007-2011"
- would indicate copyrighted additions in the years 2007, 2008, 2009, 2010,

- FAT Long File Names
- ===================
- NOTE: If CONFIG_FAT_LFN is defined in your NuttX configuration file, then
- there may be some legal, patent issues. The following was extracted from
- the entry "File Allocation Table from Wikipedia, the free encyclopedia:
- "On December 3, 2003 Microsoft announced it would be offering licenses
- for use of its FAT specification and 'associated intellectual property',
- at the cost of a US$0.25 royalty per unit sold, with a $250,000 maximum
- royalty per license agreement.
- o "U.S. Patent 5,745,902 (http://www.google.com/patents?vid=5745902) -
- Method and system for accessing a file using file names having
- different file name formats. ...
- o "U.S. Patent 5,579,517 (http://www.google.com/patents?vid=5579517) -
- Common name space for long and short filenames. ...
- o "U.S. Patent 5,758,352 (http://www.google.com/patents?vid=5758352) -
- Common name space for long and short filenames. ...
- o "U.S. Patent 6,286,013 (http://www.google.com/patents?vid=6286013) -
- Method and system for providing a common name space for long and
- short file names in an operating system. ...
- "Many technical commentators have concluded that these patents only cover
- FAT implementations that include support for long filenames, and that
- removable solid state media and consumer devices only using short names
- would be unaffected. ..."
- This Wikipedia entry has been updated with recent legal decisions in favor
- of Microsoft. Refer to:
- https://en.wikipedia.org/wiki/File_Allocation_Table#Patents
- So you have been forewarned: Use the long filename at your own risk!
- uIP
- ===
- Many lower-level networking components of NuttX derive from uIP which
- has a similar BSD style license:

- Rhombus Math Library
- ====================
- The math library used in NuttX derives from the Rhombus OS by Nick Johnson
- (with many, many addtions). The Rhombus OS is/was distributed under the ISC
- license. The ISC licsense is a permissive license that allows people do
- anything with your code with proper attribution and without warranty. The
- ISC license is functionally equivalent to the BSD 2-Clause and MIT licenses,
- removing some language that is no longer necessary.

- ======
- If you enable floating point conversions with CONFIG_LIBC_FLOATINGPOINT,
- then some files with an unmodified BSD license will be included. That
- license is similar to the above (modified) BSD license, but has an
- additional requirement that I state the following:
- "This product includes software developed by the University of

- libc/string/lib_vikmemcpy.c
- ===========================
- If you enable CONFIG_MEMCPY_VIK, then you will build with the optimized
- version of memcpy from Daniel Vik. Licensing information for that version
- of memcpy() follows:

- libs/libc/math
- ==============
- If you enable CONFIG_LIB, you will build the math library at libc/math.
- This library was taken from the math library developed for the Rhombus
- OS by Nick Johnson (https://github.com/nickbjohnson4224/rhombus). This
- port was contributed by Darcy Gong. The Rhombus math library has this

- ====================
- WARNING: Some of the information in the data tables in this file came
- from other projects with conflicting licenses: Linux and ArduCAM. Those
- both have GPL licenses. I am not sure if it is proper or not to lift the
- content of those tables and still retain this BSD license. I am guessing
- so, but I am not a copyright attorney so you should use this driver in
- products at your own risk.
