BUG? - Cannot place breakpoints in PSoC Creator 4.1

roger.2 Jul 5, 2017 9:42 AM

I have found that under certain peculiar circumstances I cannot set a breakpoint in PSoC creator 4.1. I am using a PSoC 4200 - this may not be relevant. The IDE says ...

Programming started for device: 'PSoC 4200 CY8C4245AX*-483'.

Device 'PSoC 4200 CY8C4245AX*-483' was successfully programmed at 07/05/2017 17:27:52.

Warning: Cannot set breakpoint: 'C:\PSoC Projects\Workspace1\BreakpointTest.cydsn\File1.c:16'. Encountered error (No line 16 in C:\PSoC Projects\Workspace1\BreakpointTest.cydsn\File1.c).
Warning: Cannot set breakpoint: 'C:\PSoC Projects\Workspace1\BreakpointTest.cydsn\File1.c:16'. Encountered error (No line 16 in C:\PSoC Projects\Workspace1\BreakpointTest.cydsn\File1.c).

This shows that I can single step through line 16 of File1.c but it refuses to set a breakpoint for me. I can set a breakpoint in the disassembly window by address, rather than line number. I can also set normal breakpoints in main.c.

After much head banging it appears that this peculiarity seems related to the inclusion of a file referencing C varargs functionality, as provided by stdarg.h even if this functionality is not called.

I include an offending project, stripped down to its bare essentials.

Can anybody help?

I made a few changes to have your project looking similar to my standards. Main reason seems to be the "external" in your prototype definitions. Even the keyword external in "pico_printf.h" hindered the breakpoint. The .h file for the File1.c was missing. I changed the device to a PSoC4-M which just was at hand...

I agree, your project for some reason allows breakpoints. I left out the File1.h as I added an external declaration to main.c in my original and I wanted to kieep it simple.

I have modified the your project changes slightly to include a call to the varargs function while removing all "external" keywords.

I believe these are implicit, in any case: linkage is either external or static,the default being external unless specified in declarations.

The new modified project is still not working. Thanks for your efforts though!

I enclose the new version. I know the method of calling the varargs function is not as it would be in practice.(va_start, va_end macros required).

The larger project from which this was taken does it all correctly and the pattern has worked fine in earlier versions of PSoC creator. I suspect it's something to do with the GCC toolchain.

Regards

Roger.

Try changing in Project -> Build settings -> Arm -> Compiler options -> Optimization to "none".

I have the same issue.

PSoC Creator 4.1 cannot set the breakpoint, but with the same code PSoC Creator 4.0 - can.

Welcome in the forum.

Can you please post your complete project so that we all can have a look at all of your settings. To do so, use
Creator->File->Create Workspace Bundle (minimal)
and attach the resulting file.

Having a similar problem. Am able to step through the file line by line, including stepping through the lines that I am trying to set the breakpoint on, but any attempt to set a breakpoint on a line in a file results in "Warning: Cannot set breakpoint: <file path>. Encountered error (No line xxx in <file path>).

I am able to set the breakpoints fine by function name for the functions in the file, btw.

The Same problem also for me. Everything was fine in version 4.0

Same problem here. It was working great in 4.1, now suddenly it's not. I've cleaned, wiped all non-essential files and started over from a minimal archive and I can't even set a breakpoint in main(). And yet, the debugger will stop at the beginning of main(), and single-step works fine.

Same problem for me. I Updated to 4.1 and did a clean compile. Breakpoints don't work anymore. I'm back on 4.0 now and wait for a solution.

What I see, is that I can set a breakpoint while in edit mode, but as soon as I start debug mode (F5), then the breakpoint changes to another type of breakpoint. See attached images.

Breakpoint while debug has started and stopped at main.JPG 11.8 K

Breakpoint while in edit mode.JPG 10.5 K

Same for me. I can set breakpoints in main.c, but not in other .c source code files.

Same problem. I've counseled by colleagues to postpone upgrading to PSoC Creator 4.1 until this is fixed.

Is there a straightforward way to revert projects to PSoC Creator 4.0? I cannot open the projects any longer with the older version. When I try to swap out with the old project file from before I upgraded, I get a bunch of nasty internal errors when trying to build, for example:

The breakpoint defect is fixed in PSoC Creator 4.1 Update 1. This is now available on the web or through your update manager. Sorry for the pain we caused - we failed to spot a change in the GNU C compiler that broke instruction breakpoints in our debugger.
