 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.
