hmmm, interesting. Further means as far as noticing nandtest seems to
trash the manufacturers info. Doh, I should have realised that.
And this whilst mounting jffs2:
JFFS2: Erase block at 0x00014000 is not formatted. It will be
erased nand_read_ecc: from = 0x00016000, len =
4096 nand_read_ecc: Failed ECC read,
page 0x000000b1
mtdblock_release
nand_sync: called
ok
mount: Mounting /dev/mtdblock0 on /mnt/jffs2 failed: Invalid argument
Which is where I believe I had a genuine bad block. I thought JFFS2 is
supposed to handle bad blocks? Or have I got the wrong impression...
