Hi everyone, GPL with linking exception seems relevant in this discussion -- especially since eCOS, which is also a well-known embedded OS, uses this license.
As a side note, but highly related: at Embedded World yesterday, we met with the Eclipse Foundation  guys. RIOT is now officially invited to become an Eclipse project. There are a number of advantages to be under the Eclipse umbrella: they provide legal services, and the IoT part of this umbrella  is actively helping communities such as RIOT to grow organically: in particular they promise promotion, and matchmaking with other FOSS communities and relevant industrial partners. There are however strings attached: Eclipse has good reputation as far as I can tell, but nevertheless some of our independence is lost if we join, and we have to use the Eclipse Public License . In any case, the Eclipse Foundation guys were stressing that CLAs  are crucial, whatever we do, whether we join Eclipse Foundation or not.
