Testing the Installation from a Boot Disk Test 1, Ping Target System Standard Ping Test 2, Ping Target System xPC Target™ Ping Test 3, Reboot Target Using Direct Call |
This topic describes how to install software on a target PC, boot that PC, and test the installation and connection between the host PC and the target PC. The xPC Target™ software uses a test script to test the entire installation. After you install the software, set the environment settings, and create a target boot disk, you can test your installation. This procedure assumes that you have set environment settings with xPC Target Explorer. See Environment Properties for Serial Communication or Environment Properties for Network Communication.
Insert your target boot disk into a target PC disk drive. This target boot disk contains the software to run a target PC.
To reboot the target PC, press the reset button on the PC.
After loading the BIOS, the software boots the kernel and displays the following on the target PC monitor.
If you have a keyboard attached to the target PC, you can activate that keyboard by typing C, and press the Page Up and Page Down keys to page up and down the target PC monitor.
In the MATLAB® Current Directory window, select a directory outside the MATLAB root directory.
In the MATLAB Command Window, type
xpctest
MATLAB runs the test script for the default target PC and displays messages indicating the success or failure of a test. If you use RS-232 communication, the first test is skipped.
### xPC Target Test Suite 3.4 ### Host-Target interface is: RS232 COM1 ### Test 1, Ping target system using standard ping: ... SKIPPED ### Test 2, Ping target system using xpctargetping: ... OK ### Test 3, Reboot target using direct call: ....... OK ### Test 4, Build and download xPC Target application: ... OK ### Test 5, Check host-target communication for commands: .. OK ### Test 6, Download xPC Target application using OOP: ... OK ### Test 7, Execute xPC Target application for 0.2s: ... OK ### Test 8, Upload logged data and compare with simulation:. OK ### Test Suite successfully finished
If all of the tests succeed, you are ready to build and download a target application to the target PC. See Basic Tutorial.
If any of the tests fails, see the appropriate test section:
Note This topic describes tests 1 to 4. For further details on these tests, or for a description of tests 5 to 8, see Troubleshooting xpctest Results in the Troubleshooting chapter of the xPC Target™ User's Guide. |
If you are using a network connection, this is a standard system ping to your target computer. If this test fails, try troubleshooting with the following procedure:
Open a DOS shell and type the IP address of the target computer:
ping xxx.xxx.xxx.xxx
DOS should display a message similar to the following:
Pinging xxx.xxx.xxx.xxx with 32 bytes of data: Replay form xxx.xxx.xxx.xxx: bytes-32 time<10 ms TTL=59
Check the messages on your screen.
Ping command fails — If the DOS shell displays the following message,
Pinging xxx.xxx.xxx.xxx with 32 byte of data: Request timed out.
the ping command failed, and the problem might be with your network cables.
To solve this problem, check your network cables. You might have a faulty network cable, or if you are using a coaxial cable, the terminators might be missing.
Ping command fails, but cables are okay — If the cables are okay, the problem might be that you entered an incorrect property in xPC Target Explorer.
To solve this problem, in the MATLAB window, type
xpcexplr
For the problem target PC, check that Target PC IP address, LAN subnet mask address, and TcpIp gateway address have the correct values. Change the TCP/IP options as necessary, then create a new boot floppy disk. On the target PC, reboot with the new boot floppy disk.
For a PCI bus,
Check that TcpIp target bus type is set to PCI instead of ISA.
For an ISA bus,
Check that TcpIp target bus type is set to ISA instead of PCI.
Check that TcpIp target ISA memory port is set to the correct I/O port base address and check that the address does not lead to a conflict with another hardware resource.
Check that TcpIp target ISA IRQ number is set to the correct IRQ line and check that the line number does not lead to a conflict with another hardware resource.
If the target PC motherboard contains a PCI chip set, check whether the IRQ line used by the ISA bus Ethernet card is reserved within the BIOS setup.
Ping succeeds, but test 1 with the command xpctest fails — The problem might be that you have incorrect IP and gateway addresses entered in xPC Target Explorer.
To solve this problem, in the MATLAB window, type
xpcexplr
For the problem target PCs, enter the correct addresses. Recreate the target boot disk by inserting a floppy disk into the host disk drive, and then clicking the Create BootDisk button.

This test is an xPC Target ping to your target computer. If this test fails, try troubleshooting with the following procedure:
tg=xpctarget.xpc('argument-list')where argument-list is the connection information that indicates which target PC you are working with. If you do not specify any arguments, the software assumes that you are communicating with the default target PC.
Check the messages in the MATLAB window.
MATLAB should respond with the following messages:
xPC Object Connected = Yes Application = loader
Target object does not connect — If you do not get the preceding messages, the problem might be that you have a bad target boot disk.
To solve this problem, create another target boot disk with a new floppy disk. See Target Boot Disk.
See also xpctest: Test 2 Fails in Troubleshooting in the xPC Target User's Guide. If you still cannot solve your problem, see If You Need More Help.
This test tries to boot your target computer using an xPC Target command. If this test fails, try troubleshooting with the following procedure. This procedure assumes that you have set environment settings with xPC Target Explorer. See Environment Properties for Serial Communication or Environment Properties for Network Communication.
xpctest noreboot
This command reruns the test without using the reboot command and displays the message
### Test 3, Reboot target using direct call: ... SKIPPED
Observe the messages in the MATLAB window during the build process.
Reboot fails, but build okay when reboot skipped — If the command xpctest skips the reboot command but successfully builds and loads the target application, the problem could be that some target hardware does not support the xPC Target reboot command. In this case, you cannot use this command to reboot your target computer. You need to reboot using a hardware reset button.
See also xpctest: Test 3 Fails in Troubleshooting in the xPC Target User's Guide. If you still cannot solve your problem, see If You Need More Help.
This test tries to build and download the model xpcosc.mdl. If this test fails, try troubleshooting with the following procedure:
In the MATLAB window, check the error messages.
These messages help you locate where there is a problem.
xPC Target loader not ready
Reboot your target computer. This error message is sometimes displayed even if the target screen shows the loader is ready.
