Well struggled. It is often worth the eductaional side effects.

That is precisely what I do and I comment out the MTD whinge. It is =
clearly important that SOMEONE does the ECC and it is a mild pity that =
the MTD layer assumes that only it is competant to do so.

It is probably that yaffs should get the MTD layer to do its ecc =
eventually as standard.
