| Yaffs Licence SampleWhile the Yaffs code is available free of charge under GNU General Public Licence, version 2, that entails the obligation to disclose Source Code for your application using Yaffs. An Aleph One Licence does not impose that obligation and so is attractive for proprietary projects. This sample Licence provides an example of the points we expect a Licence to cover. | ||

| Considerations in Choosing a Flash File SystemFailures in an embedded File System in a product are much more serious to the user than failures in an office computer.

| Using Yaffs with VxWorks or other RTOSs Yaffs is provided under two licences, GPLv2 and Commercial. The GPLv2 licence lets you use Yaffs freely but places you under an obligation to release your source code and OS code to your customers. Where this is not possible or you wish to avoid disclosing your source, then a Commercial Licence is needed to distribute your software which uses Yaffs. This note discusses this situation further. |
