To update the secondary bootloader (U-Boot), enter the following command: Specify IP address of the 
server being used as <server> parameter. For updates that utilize FTP or SCP server, enter a username 
(<user> parameter) and a password (<password> parameter). Specify the name of the secondary 
bootloader onto the server as <file_name> parameter (when using SCP, the full path must be as <folder>
parameter). When the command is executed, router will copy the file into its internal memory, perform 
data integrity check and save it into non-volatile memory.
