Nios II IDE Help System

Click the Memory tab in the upper-right pane of the Debug perspective to display the

Memory view. You can also point to Show View on the Window menu, and then click

Memory. This view displays the contents of memory.

The Memory view allows you to track multiple locations in memory without having to

continually type in addresses by hand. You can track constants and expressions, which

allows you to search for a memory location by symbolic name.

The following steps demonstrate various uses of the Memory view:

1. If the processor is running, click Thread [0] (Running) in the Debug view, and

then click Suspend.

2. In the Memory view, click Add Memory Monitor.

3. Type 0x00 and click Ok. Note the contents.

4. Right-click in the memory contents area, and click Format....

5. Select Column Size, and then click 2. Note how the display changes.

6. Click

Add Memory Monitor a second time.

7. Type &count and click Ok. This displays memory contents at the location where

variable count is stored.

8. Click on the highlighted values in the memory contents area and highlight just the

two digits representing the eight bit value for count.

9. Type a value, such as 66, and press Enter. Note the memory contents in the

Memory view and the value of count in the Variables view change.

10. Click

Add Rendering at the upper-right of the view.

11. Click ASCII and then click Ok. Note the additional tab displaying memory

contents in ASCII format.

Note: If the memory region displayed is located in read-only memory, the Nios II IDE

does not respond to attempts to edit the memory content.
