No effect of CONFIG_BOOTCOMMAND

Hi,
I have a problem with CONFIG_BOOTCOMMAND

//#define CONFIG_BOOTCOMMAND "run bootcmd_usb; usb stop; run bootcmd_pogo; reset"
#define CONFIG_BOOTCOMMAND "mmc init"

I'm booting ...

Jeff's u-boot is comming up and I load my new u-boot in memory.

Ok and here is the new one.

At this point u-boot should do "mmc init" but the normal steps from flash are running.

u-boot ignored my CONFIG_BOOTCOMMAND.
So what can it be, I have no idea.
Have you a suggestion?

Thanks a lot, joc

CONFIG_BOOTCMD only sets the default bootcmd value. If 'bootcmd' is already defined in your environment, then uBoot will use that instead.

jeff, thank you for your response.

I searched the directory for all files with bootcmd.
All entries that I found reference to CONFIG_BOOTCOMMAND and that is defined in include/configs/sheevaplug.h
I have also adapted CONFIG_BOOTDELAY 10
but the counter starts at 3 on boot.
The change in CONFIG_IDENT_STRING is used.
Very strange the whole thing, but surely a simple explanation.

I have a unflashed DockStar and make it work.

I think the DockStar with your uboot in flash loads bootcmd from flash, for whatever reason.
The only question is why.
A possible clue

*** Warning - bad CRC or NAND, using default environment

The boot process is looking in NAND for environment settings and
on the flashed DockStar it finds the environment settings and use them and not my default settings.
Is there a key to disable that?

Yes! I have found it.
As i wrote a simple explanation.

If defined
#define CONFIG_CMD_NAND

/*
 *  Environment variables configurations
 */
#ifdef CONFIG_CMD_NAND
#define CONFIG_ENV_IS_IN_NAND           1
#define CONFIG_ENV_SECT_SIZE            0x20000 /* 128K */
#else
#define CONFIG_ENV_IS_NOWHERE           1       /* if env in SDRAM */
#endif

uboot looks and use allways the environment in NAND.

If it disabled the default environment will be used.
