Well, it's a question of methodology.

I would start with a list of third-party software used, draw a dependency graph, attach licensing labels. It'll be readily apparent which license combinations need to be assessed and which parts are ready for immediate release.

1.) Boot code (if applicable) will not depend on anything and a source release depends on the pertinent licensing terms. If there is source, as opposed to some binary blobs.

2.) FreeRTOS is MIT-licensed. No problem.

3.) Anything from ST Microelectronics depends on how it's used. If linked against/called from FreeRTOS, no problem.

4.) Free42 (including SwissMicros derived shell) falls under the GPL.

5.) ???

I don't believe that sorting out the licensing issues is that difficult, but I'm making assumptions about how the firmware is structured.

A question that comes to mind is why SwissMicros hasn't done a partial release. I don't see a good reason why they're not publishing what they can (and must) right now and fill in the blanks in a reasonable amount of time.

Perhaps worse than the legal issues is the lack of communication.
