that would be:

drwxrwxrwx          0 .
drwxrwxrwx          0 ..
- -rwxrwxrwx       1230 config
drwxrwxrwx          0 bin

contents of /env/bin is:

- -rwxrwxrwx        817 _update_help
- -rwxrwxrwx        447 update_nfs
- -rwxrwxrwx       1362 update
- -rwxrwxrwx        285 mv
- -rwxrwxrwx       3445 boot
- -rwxrwxrwx        590 init
- -rwxrwxrwx         21 hush_hack
- -rwxrwxrwx        571 _boot_help
- -rwxrwxrwx        702 _update

and ls -l /dev prints:

cr-------- 4294967295 zero
crw-------  536870912 ram0
crw-------      11108 defaultenv
crw------- 4294967295 mem

crw-------    7340032 nor0.kernel

well, have tried to make an barebox.bin start disk with the cat
barebox.bin > /dev/sdX, but not sure how to proceed to run from sd-card.

On a different try, I copied barebox.bin on a fat12 sd partition and
tried to update on the mounted partion:

update -t barebox -d nor -f barebox.bin

but the syntax is:

type update -t barebox -d <nor|nand> [-m tftp|xmodem|nfs] [-f
imagename] to update barebox into flash

"-m" does not give my disk as source, so I guess I have to get tftp to
work..

On CD there is basically buildroot and the config files for barebox I
have attached to this mail.


Just to recall: my problem is that i do not know how to provide
"root=" parameter to my barebox environemnt. I load the zImage by
mounting partition by hand and running "bootm".

Thanks for help, Greetings,

Adam
