eth0 and usb don't work running Poplar recovery image

[apkopper]

Hello,
I'm new to the poplar board. I followed the exact instruction here "Building Poplar System Recovery Media From Source", cloned the source code and toolchains from linaro, built and ran recovery image on poplar board. However neither eth0 nor usb device worked on the board. No modules were loaded. I'd appreciate any suggestions/directions/actions to take, what to look for to resolve this. Thank you.

I noticed some failure on console during board boot up:

I attached the build output and board boot up console log.
