Hi Sean. We made PcieRpDetectTimeoutMs = 50 (0x32) in three places: 1. Stage2BoardInitLib.c: STATIC VOID FspUpdatePcieRpPolicy ( IN FSPS_UPD *FspsUpd ) { .... other code.... for (Index = 0; Index < MaxPcieRootPorts; Index++) { .... other code .... *FspsUpd->FspsConfig.PcieRpDetectTimeoutMs[Index] = 0x32;* .... other code.... } .... other code.... } 2. System Agent (Post-Mem): 3. PCH (Post-Mem): But we still see the same timeout error followed by the same exceptions. What do you suggest? Thanks, cheers! -=-=-=-=-=-=-=-=-=-=-=- Groups.io Links: You receive all messages sent to this group.
