1. Our implementations will be open source or not?
The FreeRTOS license is very liberal, and only effects changes and/or additions to the scheduler itself. In your case it sounds like your modifications are directly related to the scheduler, and therefore will be open source.
2. Can we distribute our implementation (source code) at FreeRTOS website ?
if yes then : 2.1. Can we distribute it as a part of FreeRTOS or as a separate plugin?
if no then : 2.2. Can we distribute it at our own website?
It is unlikely that this type of change would get its way into the core kernel code, but you can still distribute it on the FreeRTOS web site by using the FreeRTOS Interactive forums. See http://interactive.freertos.org . You can also distribute it on your own web site without having to worry about any licensing issue.s
3. Is FreeRTOS owned by the company(like google chrome: which is open source but
company will not distribute any kind of patches from others) or is it totally free.
I’m not sure I understand the question. The IP is owned by my company - Real Time Engineers Ltd - but it is also completely free. I don’t see these as being conflicting attributes. The code base origin and quality is tightly controlled to ensure people have a good experience, and to ensure that commercial licenses can be sold where appropriate. See:
