Hi everyone,
I have two questions. First, I lost all the files when I umount a
yaffs2 partition. I read somewhere in this mailing list that it was an
known issue from mtd. May I know if there is a quick fix for it?
Second, I tried to dd a file containing all zeros of ~155MB to the
yaffs2 partition.
~ # dd if=/dev/zero of=/mnt/mtd/zeros bs=128k count=2000
And after that, all block in that partition became bad block. I don't
think the nand had that many bad block all of a sudden. So is there a
way to "retrieve" those bad block (BTW, I know which block was bad
before this incidence)? flash_erase/all didn't help because it was
skipping all the bad block. I am using 2.6.12-rc1 kernel (from San
People for Atmel AT91RM9200). It is Samsung K9F2G08U0M (256MB, 128k
sector) Please help me! thanx.
