Betreff: [Yaffs] Re: problem in creating yaffs image
Thanks, that makes life a bit easier.

But what about that mkyaffs2image? What's its purpose all about, if it
does not work? I tried to solve the problem that the image does not get
created properly, but looking through the code, I have no idea where to
do what..
