Hi - thanks - 

I feel this isn't the case, because the boot procedure stalls before u-boot
even starts. As I understand it, u-boot is supposed to load from nand and
then launch bootcmd.scr which searches for a kernel on the sd card. However,
when I have a bootable sd card inserted u-boot doesn't even display its
initial message. I just get a short garbled message similar to:


�tذb�
$U

However its worth a try so I made a card with the newest linaro (12.02). I
don't know what version of MLO this is but it must be pretty new. It didn't
help.

I understand its not possible to just copy a new version of MLO over it
because MLO has to be on the very first sector of the card.

I don't know how to find out what version the MLO binaries I have are. the
'file' command just reports them as 'data'

I can still manually load linux from the card by typing the commands from
bootcmd.scr
