[meta-xilinx] Ethernet Issues on Custom Board using PS GEM?

[Giordon Stark]

Hi all,

We're using a custom board with the ZC706 chip.

Device Tree is here:
https://github.com/kratsg/meta-l1calo/blob/940fa27aa6c9a456ccca7ec60351c26287f9f671/conf/machine/boards/preprototype/system.dts

Notice that we had to modify it from the dts generated by Xilinx SDK since
it didn't have any details about the PHY chip (not sure if that was
intentional or not;
https://github.com/kratsg/meta-l1calo/commit/940fa27aa6c9a456ccca7ec60351c26287f9f671
).

Here is the log of the board's bootup:
https://gist.github.com/anonymous/64ab1f335514ff246d14

Notice line 163 (
https://gist.github.com/anonymous/64ab1f335514ff246d14#file-gistfile1-txt-L163)
and lines 234-238 (
https://gist.github.com/anonymous/64ab1f335514ff246d14#file-gistfile1-txt-L234-L238)
seem to point to issues with the ethernet.

At line 325, we looked at ifconfig (
https://gist.github.com/anonymous/64ab1f335514ff246d14#file-gistfile1-txt-L325)
which seems like it's showing up.

Tried assigning an IP address at line 362 (
https://gist.github.com/anonymous/64ab1f335514ff246d14#file-gistfile1-txt-L362
).

Lines 382-388 show the failed pings (
https://gist.github.com/anonymous/64ab1f335514ff246d14#file-gistfile1-txt-L382-L388)
- we have the board plugged into a router along with a computer at
192.168.0.3.

Closer to the end, we tried restarting the networking interfaces which
seems to have failed.

 I saw a previous posting here with changes that I'm going to try applying:
https://lists.yoctoproject.org/pipermail/meta-xilinx/2015-April/000959.html
which
is the following commit in my project (
https://github.com/kratsg/meta-l1calo/commit/69d89d1fc9e2489e90676569c8095509f9167226
).

If anyone has any more information about what's happening, that would be
helpful, thanks!
