I don’t think Error launching external scanner info generator is too much to worry about, I always have it. I think it’s from not having gcc included on windows path.
The debugging issues need more information, can you run openocd from the command line and have it find your hardware?
I resolved the “Error launching external scanner info generator” but still having other issues.Also,i tried to run openocd using command line but it doesn’t work.(i am using cygwin on windows for eclipse IDE).
