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

/*
* 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

Regards
Gururaja

Hi Markus Klotzbuecher,

i did and enabled,

/*
* Miscellaneous configurable options
*/
#define CFG_HUSH_PARSER 1
#define CFG_PROMPT_HUSH_PS2 "> "

#ifdef CFG_HUSH_PARSER
#define CFG_PROMPT "uboot$ " /* Monitor Command Prompt */
#else
#define CFG_PROMPT "#> " /* Monitor Command Prompt */
#endif

#define CFG_LONGHELP 1 /* undef to save memory */

#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"	\

and now when i execute the command as

uboot$ run boot_mmc
syntax error

uboot$ printenv
<snip>
<snip>
<snip>
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 stdin=serial
<snip>
<snip>
<snip>

even from command line if i give

uboot$ if mmcinit then echo fi

Quoted 1 line

i get above option

now i hvae to press ctrl+c to interrupt and come back to prompt

Quoted 1 line

<INTERRUPT>

uboot$ if mmcinit then echo fi

I think you forgot a semicolon before the "fi" or respectively after the "bootm ${loadaddr}"

Please also check out the excellent documentation:

Maybe you should learn shell syntax ?
