The FreeRTOS GPL Exception Text:
Any FreeRTOS source code, whether modi
fi
ed or in it’s original release
form, or whether in whole or in part, can only be distributed by you
under the terms of the GNU General Public License plus this exception.
An independent module is a module which is not derived from or based
on FreeRTOS.
Clause 1:
Linking FreeRTOS statically or dynamically with other modules is
making a combined work based on FreeRTOS. Thus, the terms
and conditions of the GNU General Public License cover the whole
combination.
As a special exception, the copyright holder of FreeRTOS gives
you permission to link FreeRTOS with independent modules that
communicate with FreeRTOS solely through the FreeRTOS API
interface, regardless of the license terms of these independent
modules, and to copy and distribute the resulting combined work under
terms of your choice, provided that
+ Every copy of the combined work is accompanied by a written
statement that details to the recipient the version of FreeRTOS
used and an offer by yourself to provide the FreeRTOS source
code (including any modi
fi
cations you may have made) should
the recipient request it.
+ The combined work is not itself an RTOS, scheduler, kernel or
related product.
+ The independent modules add signi
fi
cant and primary
functionality to FreeRTOS and do not merely extend the existing
functionality already present in FreeRTOS.
Clause 2:
FreeRTOS may not be used for any competitive or comparative
purpose, including the publication of any form of run time or compile
time metric, without the express permission of Real Time Engineers
Ltd. (this is the norm within the industry and is intended to ensure
information accuracy).

The standard GPL exception text:
GNU GENERAL PUBLIC LICENSE
Version 2, June 1991
Copyright (C) 1989, 1991 Free Software Foundation, Inc. 59 Temple
Place, Suite 330, Boston, MA 02111-1307 USA
Everyone is permitted to copy and distribute verbatim copies of this
license document, but changing it is not allowed.
Preamble
The licenses for most software are designed to take away your
freedom to share and change it. By contrast, the GNU General Public
License is intended to guarantee your freedom to share and change
free software--to make sure the software is free for all its users.
This General Public License applies to most of the Free Software
Foundation’s software and to any other program whose authors commit
to using it. (Some other Free Software Foundation software is covered
by the GNU Library General Public License instead.) You can apply it to
your programs, too.
When we speak of free software, we are referring to freedom, not
price. Our General Public Licenses are designed to make sure that you
have the freedom to distribute copies of free software (and charge for
this service if you wish), that you receive source code or can get it if
you want it, that you can change the software or use pieces of it in new
free programs; and that you know you can do these things.
To protect your rights, we need to make restrictions that forbid
anyone to deny you these rights or to ask you to surrender the rights.
These restrictions translate to certain responsibilities for you if you
distribute copies of the software, or if you modify it.
For example, if you distribute copies of such a program, whether
gratis or for a fee, you must give the recipients all the rights that you
have. You must make sure that they, too, receive or can get the source
code. And you must show them these terms so they know their rights.
We protect your rights with two steps: (1) copyright the software,
and (2) offer you this license which gives you legal permission to copy,
distribute and/or modify the software.
Also, for each author’s protection and ours, we want to make
certain that everyone understands that there is no warranty for this free
software. If the software is modi
fi
ed by someone else and passed on,
we want its recipients to know that what they have is not the original,
so that any problems introduced by others will not re
fl
ect on the original
authors’ reputations.
Finally, any free program is threatened constantly by software
patents. We wish to avoid the danger that redistributors of a free
program will individually obtain patent licenses, in effect making the
program proprietary. To prevent this, we have made it clear that any
patent must be licensed for everyone’s free use or not licensed at all.
The precise terms and conditions for copying, distribution and
modi
fi
cation follow.
GNU GENERAL PUBLIC LICENSE
TERMS AND CONDITIONS FOR COPYING,
DISTRIBUTION AND MODIFICATION
0. This License applies to any program or other work which contains
a notice placed by the copyright holder saying it may be distributed
under the terms of this General Public License. The “Program”,
below, refers to any such program or work, and a “work based on the
Program” means either the Program or any derivative work under
copyright law: that is to say, a work containing the Program or a portion
of it, either verbatim or with modi
fi
cations and/or translated into another
language. (Hereinafter, translation is included without limitation in the
term “modi
fi
cation”.) Each licensee is addressed as “you”.
Activities other than copying, distribution and modi
fi
cation are not
covered by this License; they are outside its scope. The act of running
the Program is not restricted, and the output from the Program is
covered only if its contents constitute a work based on the Program
(independent of having been made by running the Program).
Whether that is true depends on what the Program does.
1. You may copy and distribute verbatim copies of the Program’s
source code as you receive it, in any medium, provided that you
conspicuously and appropriately publish on each copy an appropriate
copyright notice and disclaimer of warranty; keep intact all the notices
that refer to this License and to the absence of any warranty; and give
any other recipients of the Program a copy of this License along with
the Program.
You may charge a fee for the physical act of transferring a copy, and
you may at your option offer warranty protection in exchange for a fee.
2. You may modify your copy or copies of the Program or any
portion of it, thus forming a work based on the Program, and copy
and distribute such modi
fi
cations or work under the terms of Section 1
above, provided that you also meet all of these conditions:
a) You must cause the modi
fi
ed
fi
les to carry prominent notices
stating that you changed the
fi
les and the date of any change.
b) You must cause any work that you distribute or publish, that in
whole or in part contains or is derived from the Program or any part
thereof, to be licensed as a whole at no charge to all third parties
under the terms of this License.
c) If the modi
fi
ed program normally reads commands interactively
when run, you must cause it, when started running for such
nteractive use in the most ordinary way, to print or display an
announcement including an appropriate copyright notice and a
notice that there is no warranty (or else, saying that you provide a
warranty) and that users may redistribute the program under these
Copyright
