JFFS2 writes a node at offset 0x0000e770.

After the second echo, it obsolets the old data node.

And writes the new node at 0x0000e7fc
But your messages show that the write goes to the same place.
May be (guessing):
1. Your messages are invalid?
2. Something goes on with JFFS2 wbuf and it is committed to the same
page (unlikely)?
3. Your flash driver is incorrect?
