2.2 Network Accessing

To support application development and operational requirements for various boot strategies,

the NetBootLoader provides several functions for gaining access to network services. These

functions include: access to DHCP/BOOTP servers, accessing TFTP servers, accessing FTP

servers, and having access to the target CPU from remote locations.

To achieve this, certain network parameters must first be configured. This can be done manu-

ally via a terminal (primary serial port) or dynamically via the network (an Ethernet port). If the

required parameters are known, they can be set with the NET command. Otherwise, the com-

mand DHCP makes it possible to download such parameters and to configure an Ethernet port

for network operation. Once the Ethernet port is configured, the commands TFTP and FTP are

available to download bootable images and other files as required. For remote access to the

CPU module, either telnet or the Serial Over LAN feature may be used.

The following table provides an overview of available TFTP/FTP server and remote accessing

functions.

SCRIPT - NBL command scripting Contents are executed only during boot up

SETCORE - Set or display core number For CPUs with multicore processors

SPEED - Set or display fast booting

SQ Boot Sequence Set or display boot sequence Defines the image boot order

SWAP - Set or display NBL Flash usage For CPUs with two NBL Flashes
