I'm looking for instructions/guides on getting the Beaglebone Black to load 
and run U-Boot from DHCP/TFTP (No SD and No eMMC). 
(

)

Currently, I have the Beaglebone Black looking in the correct /tftpboot 
directory, it finds the u-boot spl file and loads it, but stops with the 
following error: 

U-Boot SPL 2013.04-dirty (Jun 19 2013 - 09:57:14)

### ERROR ### Please RESET the board ###   

I'm using the latest Angstrom Beaglebone Black distribution, all I've done 
is strip the header from the MLO in order to create a U-Boot SPL file that 
the RBL will recognize. 
I'm guessing that I will need to do some customization of the U-Boot SPL in 
order to prevent it from going into USB Host mode.
 
Since I haven't built a custom U-Boot, or Kernel before, I can only 
speculate on what I'm seeing.   

Any info or guidance in this would be much appreciated!
Thanks!
