+Get the ip address assigned to eth0 and convert to hexadecimal, for example 192.168.1.2
+becomes 0xC0A80102, than configure CONFIG_NETINIT_IPADDR and CONFIG_EXAMPLES_TELNETD_IPADDR,
+also configure the router address, in this example it woukd be 0xC0A80101. After theses changes
+rebuild and load the new firmware on your board::

+ * Description:
+ *   Reset board.  Support for this function is required by board-level

+ * Input Parameters:

+ *            meaning of this status information is board-specific.  If not
+ *            used by a board, the value zero may be provided in calls to
+ *            board_reset().
+ *
+ * Returned Value:
+ *   If this function returns, then it was not possible to power-off the
+ *   board due to some constraints.  The return value int this case is a
+ *   board-specific reason for the failure to shutdown.
