SOPC warning- Quartus 12.0-

[Altera_Forum]

In my sopc builder I don't use any custom component. But it shows the following error msg.  

 cpu_0:Custom Instruction components can be edited through the component editor  Is this a problem? In nios ii IDE it doesn't work well (says Leaving target processor paused)  Thanks in advance.

Hi, you are new to NIOS II, aren't you ? 

SOPC will be unsupported. It is replaced with QSYS, quite similar. Both get still bugs (path, script, missing...)  Do you work with an Altera developpment board ? DE2-2C35 ;-) ?     --- Quote Start ---  cpu_0:Custom Instruction components can be edited through the component editor  --- Quote End ---   could you post you SOPC (image or file) ?     --- Quote Start ---  (says Leaving target processor paused)  --- Quote End ---   After programming flash, it is normal. You can "start" the processor by :  resetting your board, then the proceessor will boot, usually, at the boot sector in a Flash memory entering "nios2-terminal -g" something like that in a Nios Shell.
