Hi Jürgen,
I think you need to discuss these things with eCosCentric. I don't work for
them, I just recommend them because I know they provide very good service.
As I said before, they provide a supported version of JFFS2 for eCos. I
don't have the time right now to go and fix up the one in the public
repository.
