Subject: NAND oob bad blocks
Date: Wed, 07 Jun 2006 15:30:35 +0800	[thread overview]
Message-ID: <4486809B.6050600@singnet.com.sg> (raw)

Hi,

I'm using 2.6.11 kernel with the MTD drivers from kernel.org. On my 
board, u-boot is reporting 2 bad blocks while the kernel is reporting 
only 1 bad block.

Looking at the MTD Nand Driver Programming Interface, it says the bad 
block marker only applies fo the first page in a block. However, both 
u-boot and the Samsung documentation(K9F1208X0B)says that either the 1st 
  or 2nd page of every initial block has non-FFh data at the column 
address of 517.

What am I missing here or is this a case of old code/documentation?

Thanks,
Terence.
