Benny, part of the reason for moving from 1.0.0 to 1.1.1 was that the *only* place that could compile the original 1.0.0 code which was being burned on those original stix was Gordon's laptop (which just died two weeks ago actually). When I moved us over to a "real" build system, it was much easier to get 1.1.1 working than trying to reproduce the system Gordon had under cygwin on his machine. At the time, I was testing releases against both the original and the F gumstix, and it was working -- though I have to admit I haven't tested a -orig for a while now, and something may have broken. Could you try -r48, which is on sf.net and see if that works -- I think that was the first release we did for the new u-boot, and was tested on an original stix.
