Omega2s+ and EG25-G Interface error: ifconfig: SIOCGIFFLAGS: No such device error

[naveen_kumar]

Hi,

I am trying to run EG25-G on custom board. Used below method to install the LTE driver.

1. opkg install - Success
2. opkg install omega2-lte-base - Success
3. o2lte apn "www"

Setting APN to www
Done

1. o2lte data enable

Enabling LTE data connection
ifconfig: SIOCGIFFLAGS: No such device
/etc/rc.common: line 1: can't create /sys/class/net/wwan0/qmi/raw_ip: nonexistent directory
Done

Does anyone have any idea about what is going wrong. Do I need to add anything in the network config /etc/config/network

No, when you run o2lte apn "www" the o2lte script will make the required changes to the network configuration. See the relevant functions on Github.

After you run o2lte data enable, this line:

/etc/rc.common: line 1: can't create /sys/class/net/wwan0/qmi/raw_ip: nonexistent directory

Suggests that there is no /sys/class/net/wwan0/qmi directory. This means the OS isn't detecting the modem over USB.

Since this is a custom board, my guess is there is an issue the USB line routing.
Please see section 3.3.2 in the Omega2S Hardware Design Guide for recommendations on PCB layout for USB data lines.

@Lazar-Demin Thanks. we had issue with USB detection.
