  for development, yaffs2 may be not a _standard_ file system for Android.
  but for marketing, it is realy used as a common file system.
  as far as I know:
    some of HTC phone use it.
    some embedded developement board use it.
    it is well known in embedded area (can find many documents about it)

  thank you for your suggestions.
  I will integrate yaffs2 to my current using kernel.

  welcome any members to reply, thanks.


  and additional consult:
    is it suitable to integrate yaffs2 into upstream kernel ?

  :-)


  thanks.
