This chapter provides troubleshooting suggestions that help you to
resolve general problems in setting up the target platform and testing
devices.
If the PTC does not link to the target platform properly
(Digital display of PTC is not "XX10")
Description
When the target platform powers up, the four-digit display on the test
card indicates the state of the internal link state machine.
The two digits on the right indicate the linking state of the PTC and the
target platform. If the display settles at any other numbers than "XX10",
an error has occurred. See "Appendix" on page 5-1 for a list of all
possible states of the internal link machine.
Please try the following:
• Make sure that the PCI Express slot of the target platform is configured
as a x1 PCI Express connection.
• To make sure that the linking problem is not caused by the DUT, check
the linking state of the PTC only (in case of AIC test mode with a
plugged in DUT):
Power down the target platform, pull out the DUT and power up the
system again.
If the PTC is still not linked correctly, proceed with the next step in
this list.
• Check whether the PTC was found by the target platform:
Linux: Open a terminal window and enter lspci to get a list of all PCI
devices connected to the target platform.
