Hi,


Can you please make sure that, whether LMI interface signal can be used for root port configuration space register write operation?

  • LMI Write operations are provided for AER header logging, and debugging purposes only if refer to the user guide


From what I understand, the lmi_ack (Acknowledge signal) normally will sent back when execution is complete.

Can you please check back is anything wrong with the execution part?

    Hi Wincent_Intel,

    • LMI Write operations are provided for AER header logging, and debugging purposes only if refer to the user guide

    But we are using LMI write for Root port configuration space register operation, may be for that reason it is not working??
