Folks,
There has not been enough clarity about the terms on which people can use Yaffs and the conditions attached to different Licences. We have therefore made our position clear in the following form:

Yaffs is the property of Aleph One Limited.

Yaffs is available free of charge under the terms of the GNU Public License version 2, GPL2 given at:- http://www.gnu.org/licenses/gpl-2.0.html
See especially Sections 4, 5 and 6. These 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 static and 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.

Aleph One, as owners of Yaffs, sell 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.

This text will be posted to the list every few months to help new readers understand the situation.

Readers may also wish to look at the significant changes that have occurred at http://www.yaffs.net recently. In particular we have added videos to help people understand how to compile Yaffs into Linux, and how to get in place the tools needed to do that compilation.

Any licence-holder who would like to have their logo on the Home page should get in touch with us, please. The page displays a selection from a larger group which changes every few minutes.
