Hi
We are facing following unexpected behavior of XIO2001IZGU.
The following is our HW configuraion.
[CPU] - (PCIe) - 【XIO2001】 - (pci) - [PCI device]
[Problem]
While in aging test, CPU detects bus error suddenly and fails to communicate with PCI device.
①CPU detects error from register in PCIe module.
②Timeout occurs
③ Error registers are cleared by software
④ CPU detects error again
① to ④ situation is repeated.
And the followings are impelmented for avoiding errata.
・MSI_EN is set to 0 for not using MSI message.
・ASLPMC of XIO2001 is set to 00 for the setting of active state PM disabled
What should we check to indentify the error cause?
I appreciate if you have advice.
BestRegards
