YAFFS

Details of Dec 2001 state of nand driver, and overview of how drivers fit together for use with different hardware and filesystems. Not really intended for public consumption, but a useful backgrounder and explanation of the evolution of YAFFS.

YAFFS is, and will remain, a free-software project. That's why it is licensed under the GPL, to ensure it remains free. However, we also want to make YAFFS available to as many people as possible, and some people who wanted to use it found that they couldn't if it was GPLed. Consideration of the best way to take YAFFS forward has resulted in a dual-licensing scheme, similar to that used by MySQL AB and others. Here we explain how the various components are licensed and our reasoning for doing it this way.

While the YAFFS code is available free of charge under GPL, 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.
