How does YAFFS work?
HOWTO incorporate YAFFS in Linux
Posted May 23rd, 2005 by AdminYAFFS Direct User Guide
Posted July 26th, 2006 by WookeyYAFFS has been designed in a very modular way, with the file-system-specific code kept separate from the main YAFFS file system code. This allowes YAFFS to be ported quite cleanly to other operating systems through operating system personality modules. One such personality module is the YAFFS Direct Interface (YDI) which allows YAFFS to be simply integrated with embedded systems, with or without an RTOS.
This document describes how to use the YAFFS Direct Interface with your OS/Environment, as well as providing sufficient information to allow a preliminary evaluation of YAFFS.
YAFFS: the NAND-specific flash file system - Introductory Article
Posted July 26th, 2006 by WookeyYAFFS stands for "yet another flash file system"(*). As far as I am aware, YAFFS is the only file system, under any operating system, that has been designed specifically for use with NAND flash. YAFFS is thus designed to work within the constraints of, and exploit the features of, NAND flash to maximise performance. YAFFS uses journaling, error correction and verification techniques tuned to the way NAND typically fails, to enhance robustness. The result is a file system that exploits low-cost NAND chips and is both fast and robust. YAFFS is highly portable and runs under Linux, ucLinux and Windows CE. YAFFS is an open source project.
YAFFS Debugging
Posted September 15th, 2006 by WookeyYAFFS provides a debugging mechanism which can be controlled at runtime, or set at build time. This page descirbes the options available and how to use them, for when you need to do some troubleshooting.

Using GIT
Posted March 18th, 2010 by JennyWe now operate a GIT server for our active projects. Here we give details of the setup:-
If you just want to browse or download code then it's easiest to access the repository over the web.
If you want to use GIT directly from the command line then public read-only access is available, using the (bash) command:
git clonegit://www.aleph1.co.uk/yaffs2
