Here is how I did my kernel and root partitions, following this steps :=

addpart /dev/nand0 300k(barebox)ro,128k(bareboxenv),2700k(kernel),= -(root)
nand -a /dev/nand0.*
update -t kernel -d nand
update -t ro= otfs -d nand

Is there any specific command to erase the nand before flashing it ?

A raw image does not have any magic number you could check, so the bo= otu
command relies on the user passing the correct image.

Sorry, I meant the output of 'ls -l /dev/nand0.*' to check th= e sizes of
your partitions.
