I use NX as an endpoint to connect to the host. After NX successfully starts EP mode, I cannot see the corresponding RAM memory on the host after using the lspci command. I suspect that the following command may not have been used:
setpci -s 0005:01:00,0 COMMAND=0x02
But in fact, using the command will result in an error: setpci: Warning: No devices selected for “COMMAND=0x02”.
I guess it may be necessary to replace 0005:01:00,0 with the corresponding PCIe bridge, but at the same time, when I use lspci-v on NX, it does not display the PCIe bridge connected to the host, only the connected WiFi module.
0005:01:00.0 means this PCIe device is on controller C5.
But Orin NX does not have PCIe C5… Your EP is probably on C4…
