Which system do you use? Android, Ubuntu, OOWOW or others?

Android

Which version of system do you use? Please provide the version of the system here:

Android 14 AOSP

Please describe your issue below:

I have a PCIe data module and have reviewed the USB3/PCIe SWITCH page. According to the documentation, the PCIe/USB3 interface can be configured using the Ubuntu system.

Can the M2X WWAN extension be configured to use PCIe mode for Android OS?

PS. I am working on bringing up the PCIe data module and will implement it myself.

Thanks.

The AOSP firmware does not support the M2X interface function. Sorry, you can use the Android 9 firmware to use it

Hi,

Thanks for your reply.

I have used the M2X WWAN extensiion on Android 12/13/14 AOSP, and it can works on USB mode.
But I just hope the M2X WWAN extensiion interface can force on PCIe mode.

Please help :slight_smile:
