Hi, I just want to make sure I understand this right (I use
yaffs-direct):
The function QueryNandBlock in my low-level driver gets a pointer to
sequence number and blockstate. So I suppose those are the two values
that I must determine by reading the OOB on the chip.
Blockstate according to what I saw in the code will be either
NEEDS_SCANNING or DEAD or UNKNOWN (if the read operation failed).
Sequence can be anything in a new device depending on how the tags are
packed, but will propably be 0xffffffff which is allready higher that
the default max YAFFS_HIGHEST_SEQUENCE_NUMBER.
This causes yaffs to mark that block for later scanning, or any other
block which have the same sequence number, during boot in the function
scanBackwards and this, I think, is my problem. I see no 'format'
type of function for a new file system on a new device, so what should
I do?
Regards
