I am trying to connect an LTE modem via the mini PCIe port on the board, compiling Linux 4.9 with AOSP (Android 9).
lspci does not list any devices, and
dmesg doesn’t show that anything has been found, while showing that PCIe host is enabled.
The modem is Huawei ME906E which is connected via a mini PCIe to M.2 connector.
I’ve also tried connecting Quectel EC25-E (forgive me for not linking, new users are limited to 2 links), which I know works (runs on my RPi) directly to the mini PCIe port and get the same result – nothing listed in
lspci and no mention in
I wonder if there is any gotcha that I am missing, or if there are some sources that I could modify for debugging or for integration.
Any help would be appreciated
