KSDK1.2 License question ?

neilhancock — Tue, 29 Sep 2015 18:42:19 GMT

An open source product micropython.org part of the Python project has no Freescale software in it supporting Freescale Kinetis Processors.

I'd like to make a contribution to this open source software for some specific Kinetis processors - but I'd like to check the KSDK 1.2 /KDS3 licensing conditions allows this.

Can anybody at Freescale tell me if it would or WOULD NOT be considered part of the license - or is a grey area with unknown risk,...

I’m proposing to develop a community product “middle ware” from Freescale derived KSDK 1.x as part of an “Authorized System” for a Freescale FRDM-K64F board to glue open source software “micropython.org” developed in a “software commons” (like github.com).

The “middle ware” derived from the Freescale Licensed Software granted to me as part of KSDK 1.x download would only be part of a larger "Authorized System" –meeting a license condition - and only distributed as part of that system . The small part specifically enabling the choice of Kinetis MK64F processor.

The “middleware” as part of a larger system would contain Freescale software license as stated in each file but would NOT require other software developers to acknowledge that or any other licenses should they choose to use the software.

The “middle ware” would be of value to potential Freescale customers who purchase FRDM-K64F or MK64FN family products.

The “middleware” would likely be further developed by a community of software developers – and where it would be freely available and maintained in a “software commons” (like github.com).

The proposed “middle ware” if developed would by its nature of being “Freescale KSDK1.2 HAL and drivers” only run and drive targeted Freescale MK64FN ARM processor.

The micropython.org is a project to supply a version of the Python on embedded ARM boards, and is developed and maintained by a community of software developers and organizations all using the open source GCC ARM tools (https://launchpad.net/gcc-arm-embedded Simplified BSD Licence, GNU GPL v2, GNU GPL v3, GNU LGPL v2.1, GNU LGPL v3, MIT / X / Expat Licence).

Python Programming Language is sponsored by Python Software Foundation (PSF) a non-profit legal entity that holds and protects the intellectual property rights behind Python, keeping it free and open for all to use. ( https://www.python.org/psf/summary/ )

Micropython was initially launched by a kickstarter project with the rewards supplying a practical implementation on an STC STM32F processor.

Micropython has since been ported to other processors including STC and Texas Instruments.

However Micropython has only been ported to one version of a Freescale processor the MK20DX using open source PJRC.com software implemented on a PRJC product called the Teensy3x.

The development of a version of the software to run on Freescale processors is only possible if using the added value of the community open source development known as micropython.

I personally propose to use the resulting enhanced middleware in a product containing a Freescale MK26FNxxx processor. This product is targeted at outdoor environmental monitoring of environments that contain endangered species (as identified in the US), and likely to be open source hardware. The micropython capability would greatly enhance the usefulness of the product to scientists and other developers working in this field.

My reading of the Freescale license granted me by downloading KSDK1.2 and KDS3 (and I’m not a lawyer) is it is allowed if

a) included in Middleware that may be further copied and reproduced as part of that “Authorized System” and not on a standalone basis, as defined by the KSDK1.2 license 2.2a & 2.2c below

b) contains the language in the software source code

c) the software is not defined as Third Party in the table at the end

KSDK 1.2 (Kinetis Software Development Kit) and KDS3 (Kinetis Design Studio V3.0) license language

2.2.

I guess this has become a KSDK1.3 license question.

Further findings from different sources

On installing the KSDK1.3 on KSD300 license says

Special Source Distribution Rights Freescale also grants to you the additional right to

prepare derivative works of and to distribute Compilable Software, which is explicity marked with the

text "SOURCE DISTRIBUTION PERMISSIBLE as directed in EULA", in source form and only as part

of your own software programs that add substantial value to the Compilable Software. You may only

distribute the Compilable Software for execution on a Freescale Processor.

However this is not the same as the BSD 3 license language that is defined in some of the FTF presentations

While not legal language, marketing intention in these recent presentations

https://community.freescale.com/docs/DOC-104240 SDK Quick Start and Demo, 2015 Mar

Re: KSDK1.2 License question ?

Hi, Neil,

KSDK v1.3 (latest at the time of this writing) includes several software components, all with individual licensing. The license attributed to each component is outlined in the Software Content Register (SCR) and pasted below. The intention for the peripheral drivers and as much of the software that runs directly on the Freescale hardware is to enable them with very permissive licenses. We chose the BSD 3-Clause license such that the HAL and peripheral drivers could be used by other projects, such as micropython. Note that the KSDK is used today as the lowest layer of the ARM mbed software platform support for Kinetis -- a very similar usage to what is being proposed here.

in summary, you can take any of the BSD licensed software in KSDK and use them in other projects as long as the license requirements (the 3 clauses) are meet. Easy enough!

Many thanks for the detail.

I realized it was complex - and clear when it was the MQX and uC/OS - but hadn't realized the implications for the USB stack.

It would helpful for system design if this summary was included with KDSK releases.

Re: KSDK1.2 License question ?

mnorman — Thu, 29 Oct 2015 18:23:40 GMT

No problem. i just copied and pasted the license details from the Software Content Register that comes with Kinetis SDK today. See "SW-Content-Register-KSDK-1.3.0.txt" in the root KSDK_1.3.0 folder of your installation.
