Breakpoints not working

Hi all,
I have a simple test application just now and I can't get the debugger to stop at break points. The code is compiled as debug and I can see the debugger starting but it just carries on even if I insert break points.
Am I missing something in my build?
Cheers,
Dave...

Sometimes, the compiler flag -gdwarf-2 disappears.
At Navigator window, right-click on name of your project.
In the context menu, select Properties.
At Properties window, select C/C++ Build, then Settings, then tab Tool Settings, then GNU C Compiler.
Verify, that the compiler command line includes: -gdwarf-2
The generic way of restoring the default project setting is to create the new project, verify the breakpoints are operating, and then import your own source files.

Verify, the compiler command line has the following include (for mod5270):
-I"C:\nburn\mod5270\include"

All of the above is correct for my MOD5234.
I'll create a new project and try it that way. This is just some test code so no big issue to go this extra step.

OK, I created a new project with defaults only and still it won't debug the breakpoints.
I have recently upgraded to the latest Rel24 RC2 and suspect this may be the issue.

My wizard-generated simple project has breakpoint feature fully operational.
I use Rel24_rc2.

Can you set breakpoints in UserMain?
I had it working yesterday at one point with the same project but it is not consistent and I can't breakpoint anything before the while loop in UserMain.

My mentioned simple project has correctly operational breakpoints in UserMain() function before the while loop.
The source code is at

If you need, the project files can be sent as well.
Verify check of "Network debug" while generation of the example project with NetBurner wizard.

Hi there,
Yes, network debugging was checked and the code to enable the debugger is called within UserMain. I have a printf to confirm this.
Is strange that I can set some parts to breakpoint but others can not.!!

Dave, try putting a delay after the call to InitializeNetworkGDB_and_Wait(), like this:
Code: Select all
InitializeNetworkGDB_and_Wait();
OSTimeDly (TICKS_PER_SECOND * 2);
I ran into this problem not long after I started using the Netburner a few months ago. I haven't investigated it any further, as the simple delay fixed the problem for me. I had noticed that breakpoints deep in the code worked, and placing breakpoints during runtime also worked, but not breakpoints appearing shortly after the InitializeNetworkGDB call.
