Hi,

I have a barix ipam400 module, the development is done with Yocto. Recently I managed to modify and include the needed kernel modules into the kernel with Yocto.
However it still doesnt work. Both module work seemleslly and out of the box with a RaspberryPi, but not with this ipam400 modul. The kernel is 4.10.

The latest issue is that when I try to pull up an internet connection the error message is this:
device lo not available because device is strictly unmanage

These are the kernel module which I have included with bitbake -c menuconfig linux, they are all on the target device now:

* 

Do you guys have any idea whats wrong with this setup. I've read the out-of-tree kernel module yocto dokumentation, I did my best and had many suggestions on the forum as well.

what does NetworkManager.conf look like on the device ?
especially mark managed=true and see if that helps

Hi Khem,

There is no NetworkManager.conf file on the device. Shoudl I create one?

I'm reading the Quectel dokumentation, and it say that a *GobiNet* driver should be included as well. But there is no Yocto recipe for that
