using the default wdbpipe back end (see 5.2 Configuring and Starting a Target Server,
p.128).
The target agent can receive requests over any device for which a VxWorks
network interface driver is installed. The typical case is to use the device from
which the target was booted; however, any device can be used by specifying its IP
address to the target server.
Configuring the Target Agent for Network Connection
The default VxWorks system image is configured for a networked target. See
4.6 Configuring the Target-Host Communication Interface, p.137 for information about
configuring VxWorks for various target agent communications interfaces.
2.5.2 END Connections
An END (Enhanced Network Driver) connection supports dual mode agent
execution. This connection can only be used if the BSP uses an END driver (which
has a polled interface). With an END connection, the agent uses an END driver
directly, rather than going through the UDP/IP protocol stack.
Configuring the Target Agent for END Connection
See Configuration for an END Driver Connection, p.138 for information about
configuring the VxWorks target agent for an END connection.
2.5.3 Serial-Line Connections
A raw serial connection has some advantages over an IP connection. The raw serial
connection allows you to scale down the VxWorks system (even during
development) for memory-constrained applications that do not require
networking: you can remove the VxWorks network code from the target system.
When working over a serial link, use the fastest possible line speed. The Tornado
tools—especially the browser and the debugger—make it easy to set up system
snapshots that are periodically refreshed. Refreshing such snapshots requires
continuing traffic between host and target. On a serial connection, the line speed
can be a bottleneck in this situation. If your Tornado tools seem unresponsive over
