Can anyone give some advice?
How about using something like the following: > #undef CONFIG_SYS_USE_UBI /* Define to use UBI */ > #undef CONFIG_SYS_USE_UBIFS /* Define to Use UBIFS */ > #define CONFIG_CMD_JFFS2 /* Turn on the "fsload", "ls", and > "fsinfo" commands */ > > > #ifdef CONFIG_SYS_USE_UBIFS > > #define CONFIG_CMD_UBIFS /* Turn on the "ubifsmount", > "ubifsls", */ > /* and "ubifsload" commands. */ > #define CONFIG_LZO /* Use LZO library - needed for UBIFS > */ > #define CONFIG_SYS_USE_UBI /* Use UBI */ > > #endif /* CONFIG_SYS_USE_UBIFS */ > > > #ifdef CONFIG_SYS_USE_UBI > > #ifdef CONFIG_SYS_MALLOC_LEN > #undef CONFIG_SYS_MALLOC_LEN > #endif > #define CONFIG_SYS_MALLOC_LEN (CONFIG_ENV_SIZE + 1 * (1024 * 1024)) > > #define CONFIG_CMD_UBI /* Turn on the "ubi" command */ > #define CONFIG_RBTREE /* Red-black tree support - needed > for UBI */ > #define CONFIG_MTD_UBI_DEBUG /* Enable UBI debugging */ > #define CONFIG_MTD_PARTITIONS /* Support MTD partitions */ > > #endif /* CONFIG_SYS_USE_UBI */ > > > #ifdef CONFIG_CMD_JFFS2 > #ifndef CONFIG_MTD_PARTITIONS > #define CONFIG_MTD_PARTITIONS /* Support MTD partitions */ > #define CONFIG_MTD_DEVICE /* Support MTD devices */ > #endif /* CONFIG_MTD_PARTITIONS */ > #endif /* CONFIG_CMD_JFFS2 */ > > > #ifdef CONFIG_MTD_PARTITIONS > > /* MTD partition support */ > #define CONFIG_FLASH_CFI_MTD /* Export CFI flash to the MTD layer */ > #define CONFIG_CMD_MTDPARTS /* Turn on the "chpart" and "mtdparts" > commands */ > > /* Default MTD partition table */ > #define MTDIDS_DEFAULT "nor0=yourBoard-0" > #define MTDPARTS_DEFAULT "mtdparts=yourBoard-0:" \ > "384k(U-Boot),128k(U-Boot Env)," \ > "384k(Backup U-Boot),128k(Backup U-Boot Env)," \ > "13m(FIT Image)," \ > "2m(Backup JFFS),112m(Data JFFS);" > > #endif /* CONFIG_MTD_PARTITIONS */ _______________________________________________ U-Boot mailing list [email protected] http://lists.denx.de/mailman/listinfo/u-boot
