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 VMP3 is delivered with the NetBootLoader already installed in the onboard soldered
FLASH and is ready for operation. However, in order for the CPU board to be used in a system,
application software must be made available for use. This is accomplished by programming the
application also to the onboard soldered 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 CPU board, it checks to see if there is a valid application
programmed in FLASH and at the same time initiates a command interpreter which the opera-
tor can access either via the TERM or the Ethernet port FCC1 (FE) interfaces. If there is not a
valid application in memory, the NetBootLoader terminates the boot operation, and waits for op-
erator intervention. As this is the case when the CPU board is first powered up, the operator
now has the opportunity to program an application.
Prior to programming an application it may be necessary to configure the NetBootLoader or
perform other functions depending on the user’s application development environment or ap-
plication requirements. Once this has be accomplished and the application has been pro-
grammed, the CPU board 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 application to FLASH.
5.4.2 Accessing the NetBootLoader
Initial access to the NetBootLoader can only be achieved via the TERM interface. Prior to using
the telnet interface, the Ethernet port parameters must be set and this can only be accom-
plished initially via the TERM 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 VMP3 must
be set to 255.255.255.255 using the "net" command.
Once valid Ethernet port parameters and the telnet login password have be set, the telnet in-
terface is available for operation.
Use of the TERM 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 there is no valid appli-
cation programmed, the command interpreter is available as long as the operator requires it. If
