the autobooting function of uboot is not functioning properly on my

I have set the bootcmd and bootdelay variables, but I still can't get it to
work. I can watch the countdown hit zero, and I do not hit any buttons and
then the whole process just stops at the prompt.
If I disconnect the serial cable from the computer, it still fails to
proceed with the boot process.
Below is the dump of 'printenv' any suggestions?
Marvell>> printenv
autostart=yes
baudrate=115200
bootargs=console=ttyS0,115200
bootargs_console=console=ttyS0,115200
bootcmd=setenv bootargs $(bootargs_console); run bootcmd_mmc; bootm
0x00800000 0x01100000
bootcmd_mmc=mmc init; ext2load mmc 0:1 0x00800000 /uImage; ext2load mmc 0:1
0x01100000 /uInitrd
Can you load your uImage and uInitrd from the mmc? What version of
uboot are you running? Nowadays 'mmc init' is 'mmc rescan'.
Try to type the commands individually:
$ mmc rescan
$ ext2load mmc 0:1 0x.... /uImage
$ ext2load mmc 0:1 0x.... /uInitrd
$ bootm
and see where it stops working.
