Licensing
|
|
^^^^^^^^^
|
|
|
|
This directory contains miscellaneous NuttX add-ons and utilities.
|
|
NuttX is retained separately for maintenance and licensing reasons.
|
|
NuttX has a BSD-style license. However, the contents of this
|
|
directory have have other license restrictions.
|
|
|
|
The licensing of the components of this directory are summarized
|
|
below:
|
|
|
|
buildroot:
|
|
Description: GNU toolchain build environment. Derived from
|
|
http://buildroot.uclibc.org/
|
|
License: GPLv2
|
|
|
|
pascal:
|
|
Description: Pascal compiler with NuttX runtime add-on.
|
|
License: BSD
|
|
|
|
sims:
|
|
Description: This is a repository of instruction set simulators
|
|
that were used to verify NuttX. The licensing of the
|
|
instruction set simulators vary
|
|
|
|
sims/z80sim:
|
|
You are well comecom to use the source files provided in
|
|
this directory for any purpose. However, the core of the Z80
|
|
emulation is based on a proprietary-but-free-to-use
|
|
instruction set emulator. That emulation is not included
|
|
in this directory, but is automatically downloaded when
|
|
z80sim is built.
|
|
|
|
drivers:
|
|
Descriptions: This is a folder of drivers that are not included
|
|
in the main NuttX source tree due to licensing or other concerns.
|
|
Compatibly licensed drivers (BSD or MIT) are included in the main
|
|
source tree. These drivers have incompatible licesnes. They
|
|
may, as an example, have been leveraged from Linux and, hence,
|
|
inherit a GPL license. By installing this driver package you
|
|
agree to the licensing terms of the individual drivers.
|
|
|
|
rtl8187x
|
|
This is a USB host driver for the RTL8187x wireless LAN. Some
|
|
of the critical logic in this driver derives from Linux and,
|
|
hence, is GPLv2.
