Yaffs is fully supported...
Yaffs support is available through the Yaffs community but for those problems that aren't suitable for a public forum, we offer consultancy with direct access to our developers.
Yaffs is a safe choice...
Yaffs has a long history, coupled with continuing development. There are thousands of developers who have used it, and it's deployed in many millions of devices.
For closed source projects - try before you buy...
If you think that Yaffs might be what you need, you can test it without buying a licence.
Suitable for open and closed source projects...
If you want to use Yaffs on an Open Source project, then go ahead and download the GNU General Public Licence, version 2 form now. It is also available under a commercial Licence without the obligations entailed in the GNU GPL version.
How Yaffs works
This document gives an explanation of most of the core mechanisms that make Yaffs work. As of the time of writing this, the Yaffs2 code base includes approximately 19,000 lines of code making a very detailed discussion impractical. This document is the starting point for understanding Yaffs. Further detailed questions and discussions are welcomed on the Yaffs discussion list.
An active community...
There's an active community of people who use Yaffs and who have developed with Yaffs, just a click or two away.
Booting is fast...
It is important for a Flash filesystem to boot fast, so boot speed was a fundamental consideration in the design of Yaffs.
Tried and tested in millions of devices...
Yaffs is widely used in Linux and proprietary commercial RTOSs. It's been included in hundreds of devices, and shipped as part of Google's Android, with millions of units sold.
Yaffs is Open Source...
You can have a look at the code at any time. Download it now! And it's suitable for GPL and commercially licensed projects.
A robust flash file system...
After more than 100,000 random power-failures during reading or writing, a test file showed NO data corruption at all!
