If eCosCentric owns the copyright, they can change the license at any time. If you make a contribution under GPL, I believe they still require an assignment statement if it's not a standalone piece of code (please correct me if I'm wrong here). > I have looked at the files in eCos Pro, and majority of it has > the GPL license with the linking exception.

So in the case of the tree that I have with ARM EABI support, it was derived from an eCosPro tree. I was considering putting parts of that code back into anon CVS, but I thought about it for a while, and this is what I arrived at: In my opinion, eCosCentric as an entity, is doing the most to help and support eCos at the moment. They rely on people paying them for eCosPro in order to put food on the table. I am in the situation where I can do enhancements to eCos as part of my job, but it's not my primary job, and I get paid either way. I want to help the community at large, but not at the expense of hurting eCosCentric, as I think that will hurt everyone in the long run. Without eCosCentric, there'd be nowhere to go for eCos support when you really need it. Sure, something else could spring up in their place, but it would face all of the same issues. In an ideal world, the publicly available eCos could have all the features of eCosPro and people would still pay eCosCentric for support. Unfortunately though, things don't really seem to go that way. If people can get something entirely for free (as in beer), that's usually the end of it. As I understand it, they have the intention of releasing the code back into anon CVS at some point, but they need to recoup their development costs on it first. It's not an ideal situation from all perspectives, but it's reality. What I've elected to do instead is to honor a sort of gentlemen's agreement, where I'm not releasing the GPL'd bits from eCosPro back into the tree. When eCosCentric feels the time is right, I'll let them do it. This includes the enhancements that I've made. I've contributed them back to eCosCentric if they wish to include them. I don't think their fees are in any way egregious compared to what you'd pay for a commercial RTOS ($40K+ USD for a base license), so I'm happy to continue to support them. Anyhow, that's my $.02 on the issue. --Chris -- Before posting, please read the FAQ: http://ecos.sourceware.org/fom/ecos and search the list archive: http://ecos.sourceware.org/ml/ecos-discuss
