I tried with a zImage, here is what I'm getting :

barebox:/ bootz /dev/nand0.kernel.bb
invalid magic 0x00002018

And here the ls -l /dev/nand0.* output :

 barebox:/ ls -l /dev/nand0.*
crw-------     393216 /dev/nand0.barebox.bb
crw-------     131072 /dev/nand0.bareboxenv.bb
crw-------    2883584 /dev/nand0.kernel.bb
crw-------  533200896 /dev/nand0.root.bb
crw-------  533667840 /dev/nand0.root
crw-------    2764800 /dev/nand0.kernel
crw-------     131072 /dev/nand0.bareboxenv
crw-------     307200 /dev/nand0.barebox

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 rootfs -d nand

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