Kit Operation

3.4.3

Debugging a Project using Breakpoints

After programming a project, it is possible to debug it in CYW954907AEVAL1F EVK using the built in
debugger.

Note that the scan example used in

3.4.1 Building and Programming a Project for CYW954907AE-

VAL1F in WICED Studio IDE

section is also used here. Steps outlined in

3.4.1 Building and Program-

ming a Project for CYW954907AEVAL1F in WICED Studio IDE

should be first followed with a slight

change (adding -debug to the

Make Target command and removing run). Instead of

snip.scan-CYW954907AEVAL1F download run

The following make command should be used:

snip.scan-CYW954907AEVAL1F-debug download

If

-debug

is not added then it will be built for release. The important difference between the debug

and release configurations is optimization. Debug is built with no optimization and release is built
with optimization. It is possible to debug without using

debug

as well, but with many variables and

lines optimized away, many breakpoints might not get hit.

It should be noted that Breakpoints must be placed after starting a debug session in WICED Studio
5.0 or later. If there are any breakpoints that were created prior to the start of debug session, their
properties must be changed to be enabled for all Threads.

Perform these steps to debug the project:
1. Execute the make target described above to download the project to the device.
2. Click the arrow next to the

Debug

icon as shown in

Figure 3-7

and select

43xxx-Wi-Fi_De-

bug_Windows

. The Confirm Perspective Switch dialog appears; click the

Yes

button. The Debug

session starts and halts in the

start_GCC.s

file.

Note:

■

The Confirm Perspective Switch dialog is not displayed if you have previously selected the

Remember my decision checkbox

in the Confirm Perspective Switch dialog.

■

If any MakeFile/Build error occurs, then clean (using the

Clean

make target), re-build, and down-

load to the CYW954907AEVAL1F EVK again. The Debug session starts and halts in the

start_GCC.s

file.

■

In the Debug Perspective, the Project explorer window goes away by default. To view the source
files, switch back to the "C/C++" perspective.

■

To switch between perspectives, use the "C/C++" or "Debug" icon at the top right corner of
screen.
