Hi,
Our customized carrier board with NX SOM often shows the following pcie error messages while it is booting. System gets stuck at these error messages without entering Desktop.

Here is the full boot log:
boot_stuck_pciex1_0323.log (61.1 KB)
According to the “pcieport 0004:00:00.0: PCIe Bus Error” in log, we use a PCIe switch on the PCIE1 bus(Ctrl #4, PCIe x1). We are not sure if this boot failure issue is caused by it.
Could you help advise how to debug this kind of PCIe issue?
