Hi Tim,
Have you got "USB 2.0 EHCI debug dongle support" compiled on the 
coreboot side? If so, did you select "NET20DC and compatible" or 

What kernel is the phone running? I assume because you have the EHCI 
debug gadget complied in the Android gadget is not? How does your phone 
react to the missing Android gadget?

I gave up with that and purchased a BeagleBone Black in the end.

Perhaps Kyösti can help or explain why this isn't going to work?
