As Wolfgang pointed out, the best way is probably using scripting (and certainly not by hacking up main_loop()), and thus you won't be calling nand_raed_skip_bad() directly. But that still requires NAND to have been initialized. You need a NAND controller driver. This driver supplies board_nand_init(), or in some cases may be called by board_nand_init() that platform code supplies. I'm not familiar with OMAP chips, but perhaps drivers/mtd/nand/omap_gpmc.c is the driver you want? In which case your board config file needs to define CONFIG_NAND_OMAP_GPMC, as well as any driver-specific defines there may be. -Scott _______________________________________________ U-Boot mailing list U-Boot@lists.denx.de http://lists.denx.de/mailman/listinfo/u-boot
