Nios II console disappeared

[Altera_Forum]

hello I'm using QuartusII9.1sp2 and NiosII 9.1(Eclipse) 

 I could use NiosII normally until one day. since that day, I could not see stdout on my console in any project.  my NiosII may work finely, coz other responses give result like LED lights.  I recognized on NiosII console is always toggled off when I run niosii program.  does anyone have any idea?  thaks

Probably you changed the perspective or inadvertently saved the current one without the console window. 

In the IDE, select the Window menu, then "Open perspective" and choose the right one, if is still there. If not, select Window menu -> "Show view" -> Console  You may add other panes. When you are satisfied, select Window menu -> Save perspective as...
