On device debugging - Nokia E-50
Friday, 10 August 2007
Carbide C++ tools provide developers comprehensive features
for debugging S60 applications on pc using an emulator. Most of the issues are
resolved with emulator debugging. The behaviour of emulator is very much
similar to device, but some times when we have to test certain features which
are not supported by emulator, like making a phone call, accessing phone's
camera and radio, then we need to debug applications on the device.
Carbide.C++ developer and professional editions both support
on-device-debugging on S60 3rd edition devices. I'll explain you the steps
which I followed to debug a simple HelloWorld application on my E50.
I assume you're familiar with carbide.c++ enivironment.
What You Need?
- S60
3rd edition mobile phone - E-50 in my case. - Nokia
pc suite, I have v6.83.14.1 installed on my machine. - OR:
you can use bluetooth for on-device-debugging too. But for that your
mobile must be connected at serial port. - TRK
sisx. (It can be found @ C:/Program Files/Nokia/Carbide.c++
v1.1/plugins/com.nokia.carbide.trk.support_1.1.0.5/trk) - Carbide.c++
IDE, I installed v1.1 developer edition.
Nokia PC-suite installation:
- Install
Nokia pc suite on your machine. You can find latest version of pc suite
from Nokia's website. - Attach
your phone with pc using usb cabel. ( Data Cabel mode on mobile should be
"pc suite" mode). - Nokia
pc suite on your pc detects and installs drivers for your device. - So
please attach your phone and start the process.
PC port settings:
- OS:
Windows Xp - Go
to Control Panel->System->Hardware Tab->device manager
Expand ports(COM
& LPT) and you can find "Nokia E50 USB (COM20), like image below;
Carbide.c++ application creation and debug settings:
Create a symbian application through;
File->New->C++ application for S60 project. Now name
your project and press next to choose template "S60 3.x GUI
application", press next to select your sdk. I used S60_3rd_MR.
The rest is done by IDE and you can now find your created
application in carbide.c++.
You can find three configuration, If you see the picture
below;
1. S60 3.0 Emulator
Debug[S60_3rd_MR] - It is used for emulator build, debug purpose.
2. S60 3.0 Phone
(GCCE) Debug[S60_3rd_MR] - The one we need here to debug application on phone.
3. S60 3.0 Phone
(GCCE) Release[S60_3rd_MR] - creates sisx for release.
After selecting current active project settings, you need to
build project atleast once.
Now insert a break point by double clicking or right
clicking on desired line, I inserted in HandleCommandL function.
Mobile device settings:
Please install App TRK from C:/Program
Files/Nokia/Carbide.c++ v1.1/plugins/com.nokia.carbide.trk.support_1.1.0.5/trk
on your mobile phone using pc suite.
Start App TRK and go to Options->settings and select USB
in connection options. Please adjust your setting as shown in image below;
When done press back and Options->connect. You should
have a similar screen as below;
Carbide.c++ debug settings for On-device-debugging:
Right Click on project->debug as->debug
Select "Symbian OS App TRK" and select
"New" button located at bottom ( one time process).
The image below displays it;
You can also uncheck E32Main breakpoint as shown below;
Important:
Please make sure that port setting in 'debugger' tab of
debug are similar to 'Computer port settings', as show below;
Now press 'Debug' button to start the process.
Carbide.c++ creates sisx and installs it on device like
below;
As mentioned earlier, I inserted break point in
HandleCommandL function. So press Options (on your mobile) and select any
command to display a "Hello World!" either from a file or a resource.
And here you are paused at breakpoint inserted line in your Carbide.c++ IDE.
You can see it below;
Thanks for reading this article now enjoy coding symbian c++
with carbide.c++.
