Confused about licence

[bobc]

Hi,

In http://www.chibios.org/dokuwiki/doku.ph ... os:license states that there is a pure-GPLv3 licence option, but then in the table under "Pure GPL3" it says "Can I use ChibiOS/RT in my commercial embedded product? : no "

The GPLv3 licence allows commercial use, so the two statements conflict. Either ChibiOS has a pure GPLv3 licence option which allows commercial use, or it does not have a pure GPLv3 licence option. Which is correct?

From http://www.gnu.org/licenses/gpl-faq.html

I'd like to license my code under the GPL, but I'd also like to make it clear that it can't be used for military and/or commercial uses. Can I do this?

No, because those two goals contradict each other. The GNU GPL is designed specifically to prevent the addition of further restrictions. GPLv3 allows a very limited set of them, in section 7, but any other added restriction can be removed by the user.

The FSF is right of course it could be used in a commercial product, I should have stated "closed source commercial product" but I thought this was clear from the context.

Thanks for your clarification.

The context is far from clear, because the next line under "Pure GPL3" says "Do I have to release my source code? yes ". Therefore the context is the opposite, the context is open source commercial product.

ETA: ok, I see you have updated the page. The two conditions "can I use in closed source..." / "Do I have to release source code" are basically now saying the same thing in opposite ways.

Hello
I have a small commercial project using ChibiOS and ChibiOS-GFX.
I use GPL3 with Exception license ChibiOS. I do not want to open my code.
In describing the "Do I have to document that my product uses ChibiOS / RT?" what should I do?
Can I use the logos and names of reports that the inside is Chibios and / or GFX?.
Thank you.

Hi,

A mention that you use ChibiOS on your web site would be enough, a link even better, I would link back to your product. You may use the logo if you want.
