[Yaffs] Re: YAFFS fs images not working the way I expect

[Robert Szabo]

Hi!

Also, keep in mind that NAND Flashes are not error free and that they 
are at random places. Using dd (or other, OOB supported util) to preload 
an image on other NAND flash than it was dumped from is risky. Image 
might contain valid, live blocks where NAND has faults.

Robbie
