General Troubleshooting Hints and Tips
12-5
• USB support — Disable all USB support, including general USB and USB
keyboard support. Failure to do this will cause occasional long task execution
times (TET).
• PCI boards — Do not detect PCI boards with class code
0xff in the target PC
BIOS. Set this option to
Off to enable the BIOS to detect and configure all
boards.
What PCI Boards Are Installed on Your System?
Use the getxpcpci MATLAB command to determine what PCI boards are
installed in your xPC Target system. For example,
getxpcpci('all')
How to Get Updated xPC Target Releases
1 Start Simulink -> xPC Target -> Product News (Web).
2 Look for the section on downloading software and select the version you
want.
Are You Working with a New xPC Target Release?
If you are working with a new xPC Target release, either one you download
from The MathWorks Web site (
http://www.mathworks.com/web_downloads/)
or one you install from a CD, you must do the following:
• At the MATLAB Command Window, invoke
xpcexplr.
• Recreate your xPC Target environment (see “Serial Communication” or
“Network Communication” in Chapter 2 of the xPC Target getting started
documentation).
• Create a new boot disk. Use a new 3.5 inch disk.
• Rebuild target applications on that new xPC Target release.
What Does the Target PC Display?
From the host PC, you can view the target PC monitor with the MATLAB
xpctargetspy command.
