Hi all,

I am trying to execute some commands stored in environment as below

#define CONFIG_EXTRA_ENV_SETTINGS \ "boot_mmc=" \ "if mmcinit && " \ "fatload mmc 0 ${ramfs_addr} ${ramfs_file} && " \ "fatload mmc 0 ${loadaddr} ${bootfile}; " \ "then " \ "run ramargs fixedip addtty set_ramfs;" \ "setenv bootargs ${bootargs} ${othbootargs};" \ "bootm ${loadaddr}" \ "fi\0" \

My board config is as below

<snip> <snip>

/* * Command line configuration. * */ #include <config_cmd_default.h>

#if defined(CONFIG_MMC)

/* User serviceable stuff */ #define CONFIG_DOS_PARTITION 1

#define CONFIG_CMD_MMC //#define CONFIG_CMD_EXT2 #define CONFIG_CMD_FAT #endif

#undef CONFIG_CMD_AUTOSCRIPT #undef CONFIG_CMD_CONSOLE #undef CONFIG_CMD_ECHO #undef CONFIG_CMD_FPGA #undef CONFIG_CMD_IMLS #undef CONFIG_CMD_ITEST #undef CONFIG_CMD_LOADS #undef CONFIG_CMD_MISC #undef CONFIG_CMD_SETGETDCR #undef CONFIG_CMD_XIMG

#define CONFIG_BOOTDELAY 3 /* autoboot after 3 seconds */ #define CONFIG_BOOTCOMMAND "run rom_boot" #undef CONFIG_BOOTARGS /* the boot command will set bootargs */ #define CONFIG_TIMESTAMP /* Print image info with timestamp */

fom the command console when i type

uboot #> if Unknown command 'if' - try 'help' LC69 #> run boot_mmc Unknown command 'if' - try 'help' Unknown command 'then' - try 'help' ## Booting image at 0300000f ... Bad Magic Number uboot #>

Kindly let me know what i need to enable for this to work.

Thanks in advance
