I have an addpart tool as you can see but i cannot create a partition. In 
the /dev folder is also no /dev/nand0

Hi,

is there a /dev/nand0 device?

/env/bin/init call "addpart /dev/nand0 $nand_parts" and create these 
partitions.
Or maybe the command is not available?

do you have the partition definition in your /env/config file ?
