Hi all,

iam Michaela and iam a young Student from Germany (Ulm).
Iam writing my Diploma work about YAFFS2 to integrate in the

real time operation system INTEGRITY-178B from Greenhills.
I have four NAND chips K9K4G08U0M from Samsung, which are

complete one Device.

I think i understand this main working about yaffs2 but iam a little

bit confuse about how to mark bad blocks. Is it a real mark on the

chip like yaffs1 or is it only a intern thing from yaffs2 ? I have this
PackedTags2 with fields SequenceNumber, ObjectID, ChunkID and

byteCount but where is this field for state??

So what i have to do exactly in this function markNANDBlockBad?

Real Byte set on the device or only change this variable state of this block?

A other question is, i read YAFFS2 need this Block 0 for intern works.
So what exactly yaffs safe in this block?

Thanks very much !!

Michaela
