Unlucky :( Bear in mind the read disturb issue if/when you start getting weird failures in the field. They will be fixable by rewrite of the NANDs. > So as I understand I am on my own regarding this issue.

Not all that many people want to do such a big update to firmware already in the field - they either do incremental bugfixes or there is such high churn that they're already end-of-lifing it and selling the next thing. That's my impression, anyway. > Anyway, I will continue to work on it and hope to provide a > patch to others who may want it. It may be as simple as copying (and refactoring) the OOB layout structs, and associated tweaks; platform data and such. Figuring out how that stuff fits together is the time-consuming bit though if it's your first time grubbing around in the guts of MTD.
