Hello All on list

I am doing some tests with yaffs at the moment and have a question regarding
the sequence number.

in the docs howyaffsworks it states

Sequence Number: As each block is allocated, the file system's sequence
number is incremented and each chunk
in the block is marked with that sequence number. The sequence number thus
provides a way of organising the log
in chronological order

However when I am identifying items in the an image they are all returning
with the same sequence number

Directory: ./, Size: -1, ParentID 1,ChunkID 0, ObjectID 1, SequenceID 4096.
Directory: .//test3, Size: -1, ParentID 1,ChunkID 0, ObjectID 257,
SequenceID 4096.
Filename: test2.txt, Size: 10, ParentID 257,ChunkID 1, ObjectID 258,
SequenceID 4096.
Filename: test, Size: 9, ParentID 1,ChunkID 1, ObjectID 259, SequenceID
4096.
Filename: test4.txt, Size: 11, ParentID 1,ChunkID 1, ObjectID 260,
SequenceID 4096.
Directory: .//test5, Size: -1, ParentID 1,ChunkID 0, ObjectID 261,
SequenceID 4096.
Filename: test7.txt, Size: 11, ParentID 261,ChunkID 1, ObjectID 262,
SequenceID 4096.

I have based my code on wunyaffs which uses unyaffs from googlecode.

I would have thought each chunk received a unique sequence number but it
looks like it is block?.
