Hi,

wow, thanks. bootm worked fine. :)

*** Next step, booting from disk
I created a root fs on USB drive and tried to boot it.

usb start
ext2load usb 0:1 0x02000000 /boot/kernel-DUO-1.0.22
bootm

this works, but the kernel doesn't know where to find the root partition.
how do I have to pass the root= parameter to linux kernel?

this didn't work:
set bootargs console=ttyS0,115200 root=/dev/sda1

How do I find out the correct root device?

Or do I have to boot the "real" system after booting from initrd?


*** Last step: save settings setting for automated boot up.

I tried to save, it writes something, but after issuing "reset" it's 
back to initial values. what's wrong?

Marvell>> saveenv
Saving Environment to NAND...
Erasing Nand...Writing to Nand... done



thanks,

JPT
