The bootelf command boots from an ELF image in memory, where address is the load 
address of the ELF image.

bootelf [address]

The bootm command boots an application image stored in memory, passing any entered 
arguments to the called application. When booting a Linux kernel, arg can be the address of 
an initrd image. If addr is not specified, the environment variable loadaddr is used as the 
default.

bootm [addr [arg …]]

The bootp command boots an image via a network connection using the BootP/TFTP pro-
tocol. If loadaddress or bootfilename is not specified, the environment variables loadaddr 
and bootfile are used as the default.

bootp [loadAddress] [bootfilename]

The bootv command checks the checksum on the primary image (in Flash) and boots it, if 
valid. If it is not valid, it checks the checksum on the secondary image (in Flash) and boots it, 
if valid. If neither checksum is valid, the command returns back to the monitor prompt.

Verify bootup.

bootv

Write image to Flash and update NVRAM.

bootv <primary|secondary> write <source> <dest> <size>
