Hi Martin, All,
Further to the GPL questions, I had a chat with a couple of folk who
have worked in the space a bit as well;
Our intuitive view remains that in practice, you're probably ok. The ST
license seems to be about ensuring their IP/copyright isn't subverted or
used cut and paste style where it shouldn't be.
We speculate that "merely" having your source code referring to register
definitions and/or function calls that are in ST header files oughtn't
be an issue.
Again, none of us are lawyers...
If you'd like to ask someone who really knows, the crew at the Software
Freedom Law Center can likely give a definitive answer
If you are so disposed, it may be worth flagging that you're open to
other Free/Open Source licenses if the GPL isn't the best choice in your
case. SFLC will have a bit of an emphasis on the GPL of course :)
You could also ask ST directly, but that may take longer.
I'm not sure what the plans are on the hardware side, but last time I
dug into it in detail, the TAPR Open Hardware License seemed to be the
best combo of openness and ability to commercialise, but respect that
you may be preferring to keep the hardware IP private.
I'm also mindful that others on this list will have had far greater
experience than I when it comes to releasing hardware designs :)
So in closing, personally I think you're ok, but this is as much about
risk assessment as it is about formal legal opinion :)
