[Yaffs] [Yaffs-archive] about yaffs on NOR

[guxm]

Dear all,
    I have integrate yaffs into our system for NOR flash. It did work well. 
    
    But I noticed a serious issue : In yaffs, if a page is deleted, yaffs_DeleteChunk will write a spare data with pageStatus=0 to flash. But the spare region has already had old data, how can you rewrite a null spare to flash? 
    
    Is this the physical feature of NAND flash? Can NAND flash spare region be rewritted for more than one times? Then how can I use YAFFS on NOR flash?

Best Regards
guxm
