Running and Debugging Projects

To terminate all processes simultaneously, select the multiprocessor collection

process in the Debug view, and click

Terminate.

Note: A debug process for a multiprocessor collection remains active as long

as any of the associated Nios II hardware target configuration processes are

active. If one of the debug processes fails to start correctly or terminates early,

the other processes will continue running. You must terminate all processes

before attempting to start debugging the multiprocessor collection again.

Other debug commands, such as Suspend and Step, are not available for multiprocessor

collection process. You can control individual processors by selecting the appropriate

process in the Debug view and then using the normal debug commands, such as Resume,

Suspend, and Terminate.

Note: The buttons in the Debug view are context sensitive, depending on the process

selected. Be sure you have the correct process selected when using debug commands.

Clicking Debug does not work to restart multiprocessor collections. The button only

restarts the most recently launched Nios II hardware target configuration, not the whole

multiprocessor collection.

To navigate source code in the debugger:

The Debug view provides a convenient mechanism to jump directly to the line of code

where a processor suspends. When you suspend a process, the editor automatically

displays the source file in which the processor stopped.

Note that selecting a different process in the Debug view does not automatically change

the file displayed in the editor. You can double-click on the top-most function in the stack

trace to open the source file in the editor and display the suspended line of code.

To switch the Console view between active target connections:

Depending on the target connection settings for each of the Nios II hardware target

configurations, each processor can communicate character I/O with the Console view. An

independent terminal connection exists for each target processor, but the Console view

displays only one connection at a time. To switch between the active target connections:

1. Click

Unpin Console from the Console view's toolbar.

2. Click

Display Selected Console and select a Nios II Terminal Window item

corresponding to the desired processor.
