Not able to put breakpoint

Sandeep Krishnaswamy

Hi Champs,

Using the makefile we are buiding the libraries and then linking in the application to finally get the executables. But once i load the executables, i am not able to put breakpoint in the application as well as in the driver code.

If I can try to put breakpoint in the disassembly, it works. Even i can step through the code, bt not able to put breakpoint on a perticular line in teh source file.

I am using the same machine to build and debug the binary, even the path are same.

Tools are being used,

CCS :4.2.3.00004

DSP CG Tool: 7.3.0B3

Binary format : Coff

Any help would be appreciated.

Hi Sandeep,

Can you describe what exactly happens? Do you get some message? does it move the breakpoint to the start of the function? does it set a disabled breakpoint? When you open the breakpoints view, is there any reference to the breakpoint you tried to set?

Looks like you are not building with -g. That could impact your ability to set source line breakpoints.

Hi Ki --

I was on WebEx with Sandeep trying to get to bottom of this and we couldn't figure it out, so I asked him to post here.

He is using --symdebug:dwarf. Isn't this same as -g? I suppose he could try adding -g.

If he sets breakpoint on the symbol in the disassembly window, it correctly shows corresponding blue-dot/b/p in the .c window, but he cannot set breakpoints in the source file itself. He is using 4.2.3.

whoops. You're right. I messed that. sorry

Sandeep - can you select the show fullpath option in the breakpoints view? click on the little triangle icon at the top right of the breakpoint view. Or click on the goto toolbar icon in the breakpoint view. This should open the source file that this breakpoint is assigned to.

Just to confirm, you are building outside of CCS, correct?

0 Karl Wechsler over 14 years ago in reply to Ki

TI__Mastermind 20805 points

Yes. Building with external makefile. Outside CCS.

Hi Ki,

Yes, I am building the binaries outside the CCS. There is no CCS projcet to build the binaries. The CCS is only being used to debug the binaries.

If I put a breakpoint in the source code, it shows, ! mark with yellow background. If I move the cursor there it will show the file name with the path and also the line number, which is 100% correct.

Thanks and Regards,

Sandeep K

How did you point CCS to the location of the source files?

I am not doing anything extra for this in CCS.

Till now, my psp was RTSC compliant, but the psp which i am using now is not. Since it is not RTSC compliant, do i need to do any extra settings in the CCS or in the build?

Hi Ki,

Do i need to specify the PSP path to the CCS anywhere?

If I move the cursor on the file or on the breakpoint (with '!' mark on this), it is properly showing the PSP path. I do not know what is the problem.

Hi Sandeep

I had similar problems. See my post and analysis with a simple project example:
