No one has made a Buffallo monitor for the ARM .
you cant start an ARM , its missing to much essential firmware . Vendors want you to NOT know their h/w so they steer you into a 50 MegaByte i.D.E. , to keep you distracted , and detour you away from learning the essence of the ARM mcu .
You must use a helper host PC , which burrys too many bugs, because you dont have hands on with h/w , you are running thru a host .
Thats why Forth is stil argued at COMP.LANG.FORTH. because the people in a hurry to develope h/w , know there is only one fast way . and it is NOT software !! to operate the h/w imediately and with some s/w that does not distract you away from that h/w .
I will give a free Op Sys for ARM , it has not text , it boots in 0.1 second and has softkeys to program it in seconds . you can create new code frags in 3 seconds , test them in 5 seconds .
