Hi Charles,
  Thanks for your response.
   
  As per your suggestion I tried with empty partition. 
   
  I mounted a partition as
   
  mount -t yaffs2 /dev/mtdblock1 /mnt1
   
  then created a file using "vi" and put some contents in it.
   
  After this I save the file and then umount /mnt1
   
  When I try to mount again I get messages as "Partially written block 1 being set for retirement"
   
  When I looked in to the code I found that it is complaining because it thinks the block was retired in between. As I am new to yaffs2 I cannot understand what might be the issue.
   
  Any help/pointers in this regard would be highly appreciated.
   
  regards,
  shivas

the mkyaffsimage process does not work correctly at presents for yaffs2. This 
is mainly due to the hassles trying to get the oob data to flow correctly 
through the process.

I suggest you first try get going starting from an empty partition.
