Yaffs is the property of Aleph One Limited, and VxWorks is the property of Wind River.
Source Code for Yaffs is available to those who buy a Licence from Aleph One, at the base price of GBP10000.
To make using VxWorks easier we have written an extension of the code. It contains no WindRiver nor VxWorks code, but only our own code. It costs GBP3000. for those who have a Licence from us for Yaffs use.
The extension is now undergoing extensive testing by large companies in avionics and in industrial control; we shall report what they find.
If you would like us to describe what they report, without identifying you, please send an email request to sales@aleph1.co.uk
