TUSB7340: PCIE communication failure

Part Number: TUSB7340

Hi team,

My customer found that host couldn't communicate with TUSB7340 through PCIE after running 4~5 hours. Failure rate: 1/20.

When restart the system, the communication became normal, but after 4~5 hours, the communication became failed again, error message is below:

Processor: OpenPower. OS: Redhat7.7.

Could you help to analyze the root cause and solution? Thanks.

  • Hi Miranda,

    Can the customer confirm that power to the device was stable at the time of the failure? Also If you replace the part on the bad board do you see the same failure? If you place the failing part on a "good" board does the failure arise?
