Depends on what you want to do. It makes sense. In fact, I have asked our production software team multiple times to store the bad-block information at the factory for each device, so we can theoretically restore that information for any given device. I don't know the status of it, though. > Can the "factory BBT" be recreated using JTAG? not if you erase all inline and OOB data by something like 'nand scrub' of u-boot.
