 Dear All,

    How can I restore the 0xFF in the OOB[5]?   i understood the oob[5] is
 the bad block indicator. The YAFFS set accidentally the byte to 0x00 . I
 want to use JFFS2 but the eraseall command said they are invalid block. I
am
 sure that the block is health . So, I want to force set the oob[5] to oxFF,
 pls. how can i do? Thank you.

 Paul
