It is set in the BBT descriptor struct. Which NAND driver are you using? In order for it not to be set, the driver would have to use a non-default BBT descriptor (for bbt_td/bbt_md, not badblock_pattern) and leave out that flag. I don't see any upstream drivers (at least not under drivers/mtd/nand) that do that, so it should just be a matter of whether the driver specifies NAND_USE_FLASH_BBT in chip->options. -Scott _______________________________________________ U-Boot mailing list U-Boot@lists.denx.de http://lists.denx.de/mailman/listinfo/u-boot
