I tried using Build and Debug load with Ashling IDE. following this video exactly.

I got the terminal to display 'Hello World' a couple of times but then couldnt repeat it.
I had to make a C Project like the video.
If I tried to make a C++ project , it threw an error and wouldn't compile - another bug, It wanted to use MinGW Makefiles even though the Cmake configuration called up UNIX Makefiles!
Thats another issue though.
It really does look like Nios V is flaky along with its build tools.
