Hm, I take it then that you don't have any header/footer information
per-sector.. Does this mean you cannot detect the start of a JFFS
partition on a flash?

What I have always done is to use the first erase sector as a boot loader,
in every device I use this sector is mapped into some location that makes
this possible. The file system must always start at the second erase
sector. With FFS2 this was no problem, just find the right headers.. I was
hoping the same for JFFS?
