I need to use a pciex4 to connect to the Intel i350am4 network controller. How do I configure it to enable pciex4。

Booting is an error：

Excuse me,How can I modify to implement the requirements？
Thanks

There is AER errors in logs. most likely it is due to physical interface issue.

Please share complete details how you are connecting Intel network card to Jetson Nano’s PCIe M2 port

@omp
I only used the NANO core module, the motherboard of my own design.

If LIN0~4 of PCIe#0 is used, but PCIe#0 Lane 0 of M.2 is included in it, will the physical interface error occur?
Do I need to provide any other information?
Thanks

No, PCIe#0 supports Lane0-3, so it should not cause physical errors.

Please share,

  1. Complete kernel logs.
  2. “sudo lspci -vvv” output.
  3. i350am4 schematic page. I want to verify PCIe signal connections.

Thanks,

Hi zhangxin2289,

There is no update from you for a period, assuming this is not an issue any more.
Hence we are closing this topic. If need further support, please open a new one. Thanks
