Robert, did you fix the previous issue or reverted back the branch?
sorry, your post got snagged by my spam filter ... refresh my
memory, what was the previous issue? there have been so many.

not sure what previous issue this was, but i've made a few updates
to my barebox pages here:
http://www.crashcourse.ca/wiki/index.php/Barebox_pages
and you can see how simple it is to configure and build the barebox
bootloader for your beagle here:

at this point, if i have time today, i want to grab a kernel and
rootfs from somewhere and see if it boots fully. if anyone is feeling
particularly ambitious and wants to try that, let me know how it
works. it really shouldn't be that hard to finish this off.
