I'm running into a problem using the second interface with my Clearfog Base. I don't have an SFP to test the third interface, but the first works fine, though the second does not. I've tried images with 3.x and 4.x kernels from both SolidRun and Armbian and they all have the same behavior.

 

My first concern is whether this has worked for anyone else so that I can rule out faulty hardware. Can anyone chime in with whether they've successfully used the 2nd copper interface on a Clearfog Base?  If so, did it work out of the box, or did it require any extra steps?

 

Next, can someone more familiar with ARM SOCs and device trees comment as to whether the same device tree for the Pro should work for the Base?

 

In case it helps, here is some output I cherry-picked from the boot sequence that seems related to the NICs:

I think I found a workaround for this.

 

Is there a way to make the existing Clearfog images handle both boards? Should there be distinct images for the Base and Pro versions of the Clearfog boards?
