Here is the default configuration for bootcmd and bootargs :

bootcmd=nand read 0x6400000 0x400000 0x400000; bootm 0x6400000                                                                                           
bootargs=console=ttyS0,115200 $mtdparts ubi.mtd=2 root=ubi0:rootfs rootfstype=ubifs   

You have full printenv default value in this post :,4037.0.html

Hopes it can help you
