See especially Sections 3.a and 3.b. These and the following sections describe the obligations placed on those who distribute source and/or object code embodying or associated with GPL code, and therefore apply to all who use Yaffs under GPL.
Linking Yaffs to other software creates a derived work and our interpretation of linking includes dynamic and runtime linking. The derived work has the usual GPL obligation to release source code to anyone who asks. This remains true if you use Yaffs with another, or no, OS.
Commercial licensing
Aleph One, as owners of Yaffs, sell commercial Licences for the use of Yaffs which do NOT carry the obligations of GPL.
Contributing modifications of Yaffs code to the mainline code does not alter its Licence status.
Commercial Yaffs licences are non-exclusive, perpetual, world-wide, royalty-free and paid for with a single fee for one product. A commercial Licence entitles you to most further development and improvement of the Yaffs code.
The base price for a Licence for a single Product is GB£10,000. Sterling
