I have a device on a20, I tried to start an image from Cubietruck, everything works, but I am interested how it is possible to disconnect an error

sun7i-dwmac 1c50000.ethernet: Failed to reset the dma. 

There is no Internet connector on the Board

 

I attach the log

 

 

Apparently the script is constantly trying to raise the connection, but I do not know how to disable it. I would be grateful if someone can tell how to do it

Tell me how to get rid of these errors. My Board does not have an Internet adapter. Any help?

 

I use Armbian_5.59_Cubietruck_Ubuntu_bionic_next_4.14.65 image

My device looks like this

 

Other images

 

There is no Internet adapter in it, I do not know how to remove the initialization of this equipment, it constantly tries to turn on and adds errors to the log
