Hi Ed,

Im not sure why the boot didnt continue for you - i had a fair bit of 
trouble getting things going initially with the load address and entry 
point stuff but those settings worked for me - but the looks of things 
you have done everything as I did - im not sure why you cant get it to 
go any further - tbh I think after various randomish attempts and hints 
from the mips list found the correct load address.

I ran into some other problems with what I had planned for the omega2 
and unsupported bits so have put it aside for the time being so dont 
have the build vm I was using to create the mips rootfs but maybe worth 
a go from scratch with a current version of the freebsd src?

Just checking are your trying this on the Omega2 or the Omega2Plus? Also 
I was using a ral (editmax) wifi usb dongle and a usb hub - I cant 
remember if I removed the usb memory key before booting but maybe worth 
messing with usb devices after loading stuff from the memory key and 
before booting.

Also I seem to recall messing with the serial console perhaps - maybe 
restart you serial terminal emulator perhaps something funny there at 
boot? am pretty sure the dts stuff setup the console on the correct com 
port and didnt need to mess with that and i got console output from 
kernel boot start.

Sorry to be a bit vague but I havent messed with this for a little while 
now.

Mike.
