Introduction
The xPC Target Embedded Option allows you to boot the xPC Target kernel
from not only a floppy disk drive, but also from other devices, including a flash
disk or a hard disk drive. By using xPC Target Embedded Option, you can
configure target PCs to automatically start execution of your embedded
application for continuous operation each time the system is booted. You use
this capability to deploy your own real-time applications on target PC
hardware.
The xPC Target Embedded Option extends the xPC Target base product by
adding two additional modes of operation:
•DOSLoader — This mode of operation is used to start the kernel on the
target PC from not only a floppy disk, but optionally start it from a flash disk
or a hard disk. The target PC then waits for the host computer to download
a real-time application either using the RS232 serial connection or using
TCP/IP network communication. Control and setting of starting, stopping,
parameters, tracing, and other properties can be achieved from either the
host PC of from the target PC.
•StandAlone — This mode extends the DOSLoader mode. After starting the
kernel on the target PC, StandAlone mode automatically starts execution of
your target application for complete stand-alone operation. This eliminates
the need for using a host computer and allows you to deploy real-time
applications on PC hardware environments.
Whether you are using the xPC Target Embedded Option with the
DOSLoader
mode or the
StandAlone mode, you initially boot your target PC with DOS
from virtually any boot device. Then the kernel is invoked from DOS.
Note The xPC Target Embedded Option requires a boot device with DOS
installed. DOS software and license are not included with xPC Target or with
the xPC Target Embedded Option.
During setup of either the
DOSLoader mode or StandAlone mode, the xPC
Target Setup window allows you to create files for installation on the target
boot device. One of these files is an
autoexec.bat file. When DOS starts, it
