5.3.5 Motorola S-Records
The NetBootLoader provides one function for acquiring Motorola S-Records. The following ta-
ble provides an overview of this function.
5.4 Operating the NetBootLoader
5.4.1 Initial Setup
The AM4100 is delivered with the NetBootLoader already installed in the NBL Flash memory
and is ready for operation. However, in order for the AM4100 to be used in a system, applica-
tion software must be made available for use. This may be accomplished by programming such
an image also to the NBL Flash memory where the NetBootLoader is located.
Upon initial power up the NetBootLoader is started automatically. As soon as the NetBootLoad-
er has completed initialization of the AM4100, it initiates a command interpreter which the op-
erator can access either via the SER0 or an Ethernet interface. As long as the command
interpreter is available, the operator has the opportunity to program an image.
Prior to programming an image it may be necessary to configure the NetBootLoader or perform
other functions depending on the user’s application development environment or application
requirements. Once this has been accomplished and the image has been programmed, the
AM4100 is ready for operation.
The following chapters provide information on how to set up and operate the NetBootLoader
itself, initiation of the telnet interface, and how to program an image to the NBL Flash memory.
5.4.2 Accessing the NetBootLoader
Initial access to the NetBootLoader can only be achieved via the SER0 interface. Prior to using
the telnet interface, the Ethernet port parameters must be set and this can only be accom-
plished initially via the SER0 interface.
The operator must either manually set the parameters using the net command or dynamically
via the DHCP command. Prior to using the DHCP command, the IP address of the AM4100
must be set to 255.255.255.255 using the net command.
Once valid Ethernet port parameters and the telnet login password have been set, the telnet
interface is available for operation.
Use of the SER0 interface requires either a terminal or a terminal emulator. Use of the telnet
interface requires a remote telnet login to the NetBootLoader.
Availability of the command interpreter depends on the system status. If a valid image is not
available, the command interpreter is active as long as the operator requires it. If a valid image
is available, the command interpreter is only active for the duration of the boot wait time. If the
operator requires the command interpreter for a longer time he must terminate the boot oper-
ation before the boot wait time is exceeded.
