Depending on what the NAND controller driver requests, it could be trying to create an on-chip bad block table. If your flash is read only, then do not set NAND_USE_FLASH_BBT in the options -- or if you want to use an existing BBT but not create one if absent, provide a BBT description that lacks the NAND_BBT_CREATE option. If that's not it, then tell us which controller it is, and what sort of errors you're getting. -Scott _______________________________________________ U-Boot mailing list U-Boot@lists.denx.de http://lists.denx.de/mailman/listinfo/u-boot
