Dear "Cote, Sylvain", I re-added the mailing list, as others might be interested, too.
Also, please don't top post / full quore. Please read http://www.netmeister.org/news/learn2quote.html In message <579b119545daef4689c8fbeefec5793f01d4fdf6e...@atlmbx.verint.corp.verintsystems.com> you wrote: > The NAND layout you mean is: > > SPL (in first nand block) > u-boot config (N blocks depending on spare place allocated) > nand u-boot This is one of the options - but you can chose those as you like. > Can we do or is it a good idea to do: > > SPL > Nand u-boot > u-boot config You can of course do that as well. > Maybe in the second layout there are chances to overwrite config in > case that at some moment new bad block occurs (after few u-boot > update). In each and evary configuration you should leave some room for spare blocks in case you need them. Even better, don't use such a fixed block mapping, but use UBI instead. [Hoewver, booting from a UBI volume might be a challenge if your NAND controller reads only a small initial block like 4 KiB...] Please keep in mind that you must not use NAND like you used to use hard disk drives. Please see for example http://download.micron.com/pdf/technotes/nand/tn2917.pdf - this explains nicely why you want UBI.
