Is There Communication Between Your PCs?
Use the following MATLAB commands from the host PC to validate the
host/target setup:
•
xpctargetping
• xpctest
The xpc tar getping command performs a basic communication check between
the host and target PC. This command returns
success only if the xPC
Target kernel is loaded and is running and the communication between host
and target PC is working properly. Use this command for a quick check of the
communication between the h ost PC and target PC.
The
xpctest command performs a series of tests on your xPC Target system.
These tests range from performing a basic communication check to building
and running target applications. At the end of each test, the command
returns an
OK or failure message. If the test is inappropriate for your setup,
the command returns a
SKIPPED message. Use this command for a thorough
check of your xPC Target installation.
Communication errors might also occur in the following i ns tances:
• The target PC is running an old xPC Target boot disk or boot image that is
not in sync with the xPC Target release installed on the host PC. Create
a new boot disk or image for each new release.
