Flashing Firmware via Network
*****************************

Requirements:
  * root privileges
  * tftp-server (eg. tftpd-hpa)
  * working serial connection

Setup the router:
  1. start the serial terminal
  2. boot the router
  3. when the router shows "Press space key to stop auto run" press space
  4. enter "c" to change bootline parameters and set the following
	Board IP address                :[192.168.1.1:ffffff00]:
	Host IP address                 :[192.168.1.100]:
	Gateway IP address              :[]:
	Run from flash/host (f/h)       :[f]:
	Default host run file name      :[run.img]:
	Default host flash file name    :[bcmRTA770W_fs_kernel]:  
	Boot delay (1-9 seconds)        :[1]:

Steps:
  1. start the serial terminal and interrupt the routers boot by pressing space
  2. connect the router directly to the pc network interface
  3. set the ip address on the interface to 192.168.1.100
  4. copy the image you want to flash to /tftpboot/firmware.bin (no symlink,
     some tftp-servers do not allow this)
  5. type on the routers prompt: flashimage firmware.bin

You're done. The CFE will tell you if it was successful. If there is a message
like: ** Image information not found. **, than you're image is missing the
header information.
