After the module is up, the pcie device cannot be found, only the pcie bridge is found, as follows:

The kernel information is as follows:

Is this what is the reason？

Hello,

Welcome to the NVIDIA Developer forums! Your topic will be best served in the Jetson category.

It’s ok. Please note: AC Capacitors required on SoC RX lines (Device TX lines) on carrier board if connected directly to device. They are not placed on the carrier board if connected to a PCIe or M.2 connector. In those cases, the AC caps are on the adapter board plugged into those connectors.
