Subject: Way to clear nand bad block table
Date: Thu, 26 Jul 2012 18:25:24 +1000	[thread overview]
Message-ID: <002601cd6b08$37498d50$a5dca7f0$@cpdesign.com.au> (raw)

Hi,

Is there a way to clear the nand bad block table?

I'm not sure what happened, but I was playing around with barebox init and
didn't register the nand device - then when I booted the kernel there were a
stack of UBI errors. 
I assume this also did something to the bbt as subsequent barebox startups
give a heap of bad block messages. Note not all blocks are bad - tested with
nandtest and there's still some R/W going on.
All the code I looked at seemed to indicate that once a block is marked bad
you can't go back.

Any ideas much appreciated.

Cheers,
Marc
