B.8 Exploring the Code|Lab Debug Windows

This section discusses some basics of the debug environment. Some of these windows an d concepts

have been dealt with during previous exercises in this man ual. However, many new window s are also

discussed and basic interaction exercises are given. Begin this section by launching the Code|Lab

Debugger environment and connection via the JTAG port.

B.8.1 Toolbar Icons

Placing the mouse arrow on any icon displays the text functio n of that icon. When the icon l aunches a

special window (i.e., Watch, Memory, Call Trace, etc.), the icon brings that window up on the first

click and removes the window when pressed again.

B.8.2 Workspace Window

Click on the Workspace icon. Click on the Files and Brow se tabs and examine the contents. Note that

there are more files than the original source files. When you doub le-click on the source files, blink.c

and led.c, the source window appears for that file. When you double-click o n an included file, the

debugger is not be able to find the file.

B.8.3 Source Code

The source code windows are opened by double-clicking on the source files in th e Workspace

window under the files tab. Viewing o f mixed Assembly and C code or C code only, is controlled by

the tabs at the bottom of these windows.

B.8.4 4 Debug and Console Windows

The Debug window displays d ebugger activity messages whi le the Debug tab is displayed. S cript

commands can be entered manually at the top o f the window. Serial output is displayed while the

Console tab is active. Command s for the running application can be entered at the top of th is window.

B.8.5 Memory Window

Click on the Memory window icon. Change the address at the t op of the window to 0xffffe100 and

click on the green arrow to the righ t (or press Enter). This changes the viewable star ting address of the

Memory window. The ATU header begins at 0xffffe100 and contains a known numb er (8086). Also

look at the base and limit re gisters for the memory and Flash devices, at 0xffffe508 and ffffe688

respectively, since they were initialized by RedBoot. Use the Intel® 80332 I/O Processor Developer’s

Manual, to see what the values mean.

Note: The tabs at the bottom allow the selection of two memory regions to observe.
