[VIM3][AOSP] How to configure the "M2X WWAN extension" to PCIe mode by default

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:
