Hi,
I have read this thread as I'm currently having this problem happening to
me on a BeagleBone Green.
According to this thread, recent kernel versions should not have a problem
as there is code that should be able to workaround the hardware problem.
I am currently running:
- U-Boot 2016.09-00002-g03e9979
- Kernel 4.4.26-ti-r59
- The image is a derivative of Debian Image 2016-09-04
When not working:

When working as expected:

When it's not working, there is no light on the ethernet port at all and we
can see the following later in kern.log that would suggest it to be working:

Still no lights on the eth port.
So my question, is there a patch that is not applied in the kernel that you
built and that is install when using /opt/scripts/tools/update_kernel.sh
that should be applied ? Or am I missing something for the workaround to
actually work ?
What am I missing ?
Any help would be appreciated
