We have a MINIPCIE connector on our custom Jetson ORIN NX/Nano carrier board.
Minicard connector is connected to PCIE2_RX1, PCIE2_TX1 PCIe lanes and also to USB interface.
It work well with a PCIE bus based card.But when with a USB bus based card(a LTE module card) it can not work.
The cause of the problem is the PEX_RST is low after system boot complete. The USB bus-based card use the PEX_RST signal as a reset input.
Can you please suggest how to keep the PEX_RST high when there is no PCIE end points detected.
