PCIe EP device getting failed to enumerate always
I have a pcie EP(Endpoint) device & host Linux PC is acting as RC(Root-Complex).
Setup Info: For Linkup, I turn on the host PC & then turn on EP device (as the clock is coming from host PC) & run pll-lock script for EP device & then I restart the PC(without full power-cycle).
Issue: Now, my EP will be enumerated sometimes only(3 out of 10) times but once link-up,restarting the host PC or power-cycling the EP device will result in linkup always.
Is this related to BIOS/PCIe bus syncing? What may be the cause?Any suggestions.
