Sure. In case it's not clear, let me clarify what the issue was: the MTD partition has one size in Linux (4072 EB) and another size in U-Boot (4076 EB). When the map was built by Linux's Fastmap, it contained a number of PEBs that conflicted with the number of PEBs U-Boot's Fastmap code was expecting (becase Linux EB != U-Boot EB). Not sure how you would detect such a mismatch, but it was a very good idea to print a noisy warning :-) We were effectively running without fastmap so far, becasue neither U-Boot nor Linux could find a proper fastmap and attach the UBI partition using it. Hope it's clear. -- Ezequiel García, VanguardiaSur www.vanguardiasur.com.ar _______________________________________________ U-Boot mailing list U-Boot@lists.denx.de http://lists.denx.de/mailman/listinfo/u-boot
