EG25-G LTE module integration with AM62 2GB

Hello,

I am currently working on AM62 SoM 2GB + Dahlia Carrier Board Rev 1.1 with torizoncore OS 6

I am unable to integrate the Quectel EG25-G LTE using the developer documentation.
The modem is still unrecognized.

Can you share relevant information or have a short call to get the modem working?

In my company we have working device with EC21. Could you provide lsusb and dmesg output?
LTE modem info should be visible.

You probably need to do following steps:

  1. Check if modem is recognized by lsusb command
  2. Check in dmesg output if the modem is recognized by kernel and appropriate driver is loaded
  • if not:
    You need to enable driver:
    CONFIG_USB_SERIAL_OPTION
    You also need to patch kernel and add your modem model to /drivers/usb/serial/option.c driver and do other minor modifications. see here:
  1. You need ppp package and quectel-ppp scripts
    See this meta-layer:

it consists also patches for linux-yocto and raspberrypi patches. You need similar in your kernel
