Actually, Chris did give you some valuable feedback.  You had
the basic stuff going using VirtualBox, albeit with problems.
Now that you've tried CygWin, you can't even get that far.
Not surprising given all the troubles folks have had with
CygWin over time.

Go back to VirtualBox and _really_ try to figure out what your
trouble is.  This does work - has for many folks - so you must
just have something setup wrong, most likely the actual serial
connection to your board.

One question - when you originally reported that you could
get the RedBoot prompt in your minicom window and then had
trouble getting code to download via GDB, did you still have
the minicom window open?
