Nios II IDE Help System

Note: You must click in the margin to the left of the line of code. Clicking

within the editor does not affect breakpoints.

7. Click Resume in the Debug view. The processor resumes and then suspends

just before executing the line of code with the breakpoint. The editor displays an

arrow in the margin next to the suspended line of code. It might take a moment

for the program to execute to the breakpoint. Resume again to iterate through the

loop another time.

To remove a breakpoint:

Double-click the

breakpoint symbol in the margin. You can also right-click the

breakpoint symbol, and then click Toggle Breakpoint.

To disable a breakpoint:

Right-click the

breakpoint symbol, and then click Disable Breakpoint. Disabling

temporarily prevents a breakpoint from suspending the processor while leaving it in place

for future reference.

To use Breakpoints view:

1. Click the Breakpoints tab in the upper-right pane of the Debug perspective to

display the Breakpoints view. This view displays the location and status of all

breakpoints you have previously set on specific lines in the code every time the

processor hits a breakpoint or suspends. Values that have changed since the last

time the processor suspended display in red.

2. Right-click a breakpoint in the list, and then click Enable, Disable, or Remove to

change the status of the breakpoint.

The Breakpoints view also displays watchpoints. Refer to Related Topics

for more

information about debugging with watchpoints.

Several default views in the Debug perspective help you to organize, navigate, and analyze

your project during a debug session. The Nios II IDE updates each view every time the

processor hits a breakpoint or suspends. Values that have changed since the last time the

processor suspended display in red.

To view disassembly:

When the processor suspends, Disassembly view automatically appears. You can also open

the Disassembly view from the Window menu by pointing to Show View, and clicking

Disassembly. This view displays the assembly language instructions interleaved with the

C/C++ source code.
