Hi Marco,

I just had the same problem.
See whether in

drivers/mtd/maps/mb_auto.c

around line 45

#define BUS_WIDTH 2

is wrongly set to 4 instead of 2 ?

If not, search the last two weeks for "problems with flatfs" and netflash not 
working. I needed to rease the flash before I could load a new working image 
to flash.

greetings, Sigi
