<P>I think it may be a fault of nand control signal. you have to check the control signal timing by osiloscope. all operation are needed timing check.<BR>

<BR>
Hi, <BR>
<BR>
I am trying to put yaffs2 on to the Samsung K9F1G08 nand. I am using <BR>
2.6.10 kernel. <BR>
<BR>
I observed that all blocks used by the yaffs are being marked bad <BR>
block by mtd, and as per the info i got from mailing list, I commented <BR>
out the bad block marking part in the mtd. With this yaffs2 is <BR>
mounting. <BR>
<BR>
And when yaffs tries to write to nand flash, the mtd nand_write <BR>
function modifies the ecc part and the oobdata gets modified. So I <BR>
modified the nand_write not to recalculate the ecc, but to just write <BR>
same oobdata from yaffs to the nand. <BR>
<BR>
<BR>
Are these methods correct? Is there better way or patches available for these ? <BR>
<BR>
How does the yaffs2 handle a genuine bad block in the nand flash? <BR>
<BR>
Thanks, <BR>
Naushad <BR>
