Then I came across this one thread in Sparkfun. The change seems
to make sense as well so I gave it a try.
http://forum.sparkfun.com/viewtopic.php?f=18&t=24946
It does not seem to help either.
But then I find out actually my V8 J-Link works once in about 3 times for
EK-LM3S1968 demo board. It works even though that there are still
quite a bit of error message but it seems to work.
With the on-board TI/Luminary interface, OpenOCD always works.
