My system has the xps_ethernetlite instantiated. I did run petalinux-copy-autoconfig prior building the kernel. And I do have driver entry for the emac in .mss file. I think I figured the problem after I sent my question. I had to enable the "Xilinx 10/100 OPB emaclite" option under the device driver->network device support->Ethernet page in the config menu. In addition the default option "Xilinx 10/100 OPB emac" must be disabled. Otherwise it will be picked up instead of the emaclite. Now I can compile through the kernel. But I still have not tried running on hardware yet. Hopefully this will work.

Some things to check, from most to least obvious
1. Does your system have an opb_emac controller in it?
2. Have you run the "petalinux-copy-autoconfig' script from within your
HW project
3. Does your MSS file have a driver entry for the EMAC( even just
"generic" driver).
Regards,
John
