Hi folks

One piece of the yaffs2 puzzle that has been missing forever is some means of 
extracting/loading images from/to flash and being able to manipiulate these 
on the host.

This is generally thwarted by different flash drivers having different ecc 
layouts.

What I have in development is something called ymemtool which is intended to 
do all the nandread/nandwrite functions with a yaffs slant.

In the fullness of time, ymemtool will be able to do all of:

1) Tell us info about the flash including the oob layout.
2) Read the contents of flash, apply the oob layout and so write an image file 
in a consistent format.
3) Read a consistently formatted image file, apply the oob layout and write to 
nand.

At this stage, (1) works and (2,3) are work in progress.

Then a host-side program will be able to read/write the consistently formatted 
image file.
