It looks like a very low-level problem, either with flash character driver or
the hardware itself. If I try to read the contents of flash (i.e. dd
if=/dev/mtd0 of=test count=2000) I get all zeroes, which obviously isn't true:
I'm loading u-boot from NAND, therefore it has to be there (and I've erased the
rest, so it should be all 0xFF). At the kernel loading the flash is detected
though:
