i am currently trying to evaluate a mini PCIe Wifi Module (Silex SX-PCEAC2) for use with a Xavier NX. To do that I am using a Xavier NX Developer Kit with a DeLock 62848 M.2 Key A+E male > 1 x Mini PCIe Slot half size adapter.
When I tried that on regular x86 PCs the module always worked.
lspci 02:00.0 Network controller: Qualcomm Atheros QCA6174 802.11ac Wireless Network Adapter (rev 32)
But when I try this with the Xavier NX the module does not even show up in lspci. When using lsusb I can see the Bluetooth Interface that is also on that module.
Is there anything special about the M.2 Key A + E interface on the Xavier NX ( or the Dev Board ) that could cause that?
