the autobooting function of uboot is not functioning properly on my sheevaplug with debian.

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.
