OsmocomBB

Motorola C188 with Osmocombb firmwre (RAM version) can't scan out any base stations.
I tried to install Osmocombb on my single board computer (OrangePi Zero). By the way, There is not this problem on the virtual machine which bases on my x64 laptop.
When I try to upload the firmware to C118, no error

----------------------------------------

Then I opened a new terminal window, tried to scan base station, and got stuck at this notice.

Layer2 socket failed
-----------------------------------------

I lost my patience and removed connector from the USB port, and show a notification:"layer2 socket failed "
Before this step, I never had any errors. All steps were compiled successfully.

Environment:
Single board computer:OrangePi zero
Processor:Allwinner H2+(armhf)
OS:ArmBian Ubuntu 3.4.113 (xenial 16.04)

other useful information:
1.GnuArmToolchain:gnu-arm-build.3.sh(gcc-4.8.2/binutils-2.21.1a/newlib-1.19.0)
2.libosmocore osmocom-bb are both from the official git website.

In addition, my C188 had changed filters.

There are some other details that are not in it. But if you want to know, you can reply.
I am a new one in this website. Thank to everyone who can help me.:lol
