+//! <h1>Ethernet Boot Loader Demo (boot_demo_emac_flash)</h1>

+//!

+//! An example to demonstrate the use of remote update signaling with the

+//! flash-based Ethernet boot loader.  This application configures the Ethernet

+//! controller and acquires an IP address which is displayed on the screen

+//! along with the board's MAC address.  It then listens for a ``magic packet''

+//! telling it that a firmware upgrade request is being made and, when this

+//! packet is received, transfers control into the boot loader to perform the

+//! upgrade.

+//!

+//! This application is intended for use with flash-based ethernet boot

+//! loader (boot_emac_flash).

+//! 

+//! The link address for this application is set to 0x4000, the link address

+//! has to be multiple of the flash erase block size(16KB=0x4000).

+//! You may change this address to a 16KB boundary higher than the last

+//! address occupied by the boot loader binary as long as you also rebuild the

+//! boot loader itself after modifying its bl_config.h file to set

+//! APP_START_ADDRESS to the same value.

+//!

+//! The boot_demo_flash application can be used along with this application to

+//! easily demonstrate that the boot loader is actually updating the on-chip

+//! flash.
